Where to find FDEs and what signals matter

FDEs rarely have that exact title. You are hunting for people who blur the line between engineer and customer.

Start with engineers who have done consulting, implementation, or solutions work at AI-native companies. Look for people who have shipped code inside a customer's environment, not just their own company's repo. The best FDEs have client-facing scar tissue: they know what breaks when a sales team over-promises, and they know how to fix it at 11pm without escalating.

In LATAM specifically, target engineers from MercadoLibre, Globant, Avature, and Totvs who have US client exposure. Colombia's Ruta N corridor in Medellin produces strong candidates. Brazil's FAANG alumni who moved back after remote-first opened up are underpriced for what they can do.

LinkedIn

5+ years, current Engineer title. Filter for Palantir, Scale AI, Databricks, Snowflake, and Weights and Biases alumni. Connection to "customer" or "enterprise" in the experience description is a hard filter.

GitHub

Public LLM orchestration, RAG, and production AI repos. Active contributors with stars greater than 50 and followers greater than 100. Commit history matters more than follower count.

Communities

Hugging Face forums, LangChain Discord, Latent Space Slack, and the MLOps Community. Post a specific problem and watch who gives the most useful answer. That person is your candidate.

LATAM specifically

Colombia: Ruta N Medellin, Universidad de los Andes alumni. Brazil: FAANG returnees, Nubank and Itau tech alumni. Argentina: MercadoLibre and Globant engineering alumni.

2Boolean strings

Copy-paste sourcing strings

Use these on LinkedIn Recruiter, GitHub, and X. Tweak the company names to match your stack.

LinkedIn primary string
("Forward Deployed Engineer" OR "Solutions Engineer" OR "Implementation Engineer" OR "Staff Engineer") AND ("LLM" OR "generative AI" OR "large language model" OR "AI deployment") AND ("Python" OR "JavaScript") AND ("customer" OR "enterprise" OR "production")
LinkedIn for AI-native company alumni
("Software Engineer" OR "ML Engineer") AND ("Anthropic" OR "OpenAI" OR "Cohere" OR "Mistral" OR "Hugging Face" OR "Scale AI") AND ("deployment" OR "integration" OR "customer" OR "production rollout")
GitHub search
language:Python language:JavaScript topic:llm topic:ai-deployment stars:>50 followers:>100
LATAM-specific LinkedIn string
("Ingeniero de Software" OR "Software Engineer" OR "Solutions Engineer") AND ("LLM" OR "Python" OR "integración" OR "despliegue") AND ("cliente" OR "customer" OR "enterprise") location:"Colombia" OR "Brazil" OR "Argentina" OR "Mexico"

Time-saving move: Run the GitHub string first and find 5 to 10 active contributors, then look them up on LinkedIn. GitHub activity filters out people who only talk about AI and actually shows you people who build with it.

3Initial screen

The 30-minute call that cuts 70% of candidates

Run this yourself or delegate to a senior recruiter. Goal is not to evaluate depth. Goal is to confirm this person has lived in production with customers.

Most candidates who apply to FDE roles have never actually done FDE work. They are backend engineers who want to try something new or solutions engineers who want to code more. The screen below reveals that fast. You are looking for specific stories, not general claims.

Screen questions
Question 1
Walk me through the last time you deployed something into a customer's production environment. What was the stack, what went wrong, and how did you fix it?
You are screening for real deployment experience, not sandbox demos. Vague answers here mean they have not done it.
Pass signal: Specific customer name (or description), specific technical failure, specific fix with a timeline.
Question 2
Tell me about a time a customer pushed back hard on your technical approach. What did they want, what did you want, and what actually shipped?
FDEs need to hold their ground technically while keeping the customer relationship intact. This question reveals both.
Pass signal: Candidate can articulate both sides clearly. Red flag if they always just did what the customer wanted.
Question 3
Rate yourself 1 to 10 on Python, JavaScript, and SQL. Then prove one of those ratings to me in 60 seconds.
Self-assessment calibration plus a live pressure test. You want honest raters who can back it up, not 8s who freeze.
Pass signal: Honest score (6 or 7 with a good explanation beats a 9 who stumbles). Can explain a real technique or pattern on the spot.
Question 4
What does your relationship with a customer's engineering team look like 90 days in? Who do you talk to, how often, and about what?
Tests whether they understand the ongoing nature of FDE work vs treating it as a project with an end date.
Pass signal: Describes specific touchpoints, mentions both business and technical stakeholders, shows awareness of trust-building over time.

Red flags in the screen

  • Cannot name a specific customer or project
  • Describes work in vague team terms ("we built...")
  • Has never shipped into a customer's environment directly
  • Treats the role as a step toward a pure IC engineering role
  • Gets defensive when asked to prove a technical claim

Green flags in the screen

  • Names specific customers and specific problems
  • Uses "I" not "we" when describing decisions
  • Has opinions about what good FDE work looks like
  • Asks smart questions about your customers and their stack
  • Can move between technical detail and business context fluidly
4Hiring manager interview

The 60-minute depth eval

This is where you separate people who talk about production from people who have lived in it. Block 60 minutes. Go deep on two or three areas rather than covering everything.

Technical depth questions
Question 5
Walk me through how you would architect a RAG system for a B2B SaaS customer that has 50,000 support tickets and wants AI-powered search. What would you build, what would you buy, and what would you avoid?
Tests practical AI architecture judgment and whether they default to over-engineering or pragmatic solutions.
Pass signal: Asks clarifying questions before answering. Mentions tradeoffs not just a stack. References real tools they have actually used.
Question 6
A customer's LLM integration is hallucinating 15% of the time in production. It shipped last week. Walk me through your first 48 hours.
Real production incident response. Tests both technical chops and customer communication skills simultaneously.
Pass signal: Immediately mentions communicating with the customer before fixing the code. Has a debugging methodology. Does not pretend this is a solvable problem in 48 hours.
Question 7
What is the most important thing a non-technical customer success manager needs to understand about how LLMs actually work? How would you explain it?
Tests communication ability to non-technical stakeholders. FDEs fail here when they cannot translate.
Pass signal: Uses a clear analogy. Does not condescend. Gets to the practical implication for the customer's business.
Customer and scope questions
Question 8
Tell me about the most demanding customer you have ever worked with. What did they want that was unreasonable, and how did you handle it?
Pass signal: Has a real story. Shows they pushed back professionally. Did not just do what the customer wanted at the expense of the product or team.
Question 9
How do you decide when to write custom code for a customer vs pushing them toward the standard product path?
Pass signal: Mentions internal alignment with product or engineering. Thinks about maintenance burden and not just making the customer happy right now.
Question 10
What would a 90-day plan look like for your first customer at this company, starting from their contract being signed?
Pass signal: Breaks it into discovery, build, and stabilization phases. Mentions stakeholder mapping. Does not assume they know the customer's stack before talking to them.
5Technical take-home

A 3-hour scoped take-home assignment

Keep it real. Use a problem that mirrors actual work at your company. Respect their time by being specific about scope.

Before you send this: Tell the candidate exactly what you are evaluating (code quality, communication in the README, and decision rationale) and give them a hard time cap. Three hours max. Candidates who go 8 hours are not showing hustle, they are showing poor scope judgment, which is a bad sign for an FDE.

Assignment brief
Context: A mid-market B2B SaaS customer has 40,000 historical support tickets in CSV format. They want a simple semantic search interface so their support team can find similar past tickets when a new one comes in. Your task (3 hours max): 1. Build a working prototype. Does not need to be production-grade. Use whatever stack you are comfortable with. 2. Write a short README (under 500 words) explaining: a. What you built and why you made the key technical choices b. What you would do differently with 2 weeks and a real customer environment c. The top 3 risks if this goes to production as-is 3. Include one paragraph you would send to the customer's VP of Support explaining what you built in plain language. What we are evaluating: - Does it work? - Are the tradeoffs clearly articulated? - Can you communicate about it to a non-technical stakeholder?
Debrief questions (30 min after submission)
Question 11
Walk me through the biggest tradeoff you made. What would you have done differently with more time?
Pass signal: Has a clear, specific answer. Did not try to hide shortcuts. Shows they were thinking about production from the start.
Question 12
The customer's VP of Support reads your paragraph and asks: "What happens when a ticket matches multiple past tickets that have different resolutions?" How do you respond?
Pass signal: Gives a clear technical answer followed by a practical recommendation. Does not get flustered by the curveball.
Question 13
If this customer comes back in 6 months and says the search quality has gotten worse, what is the first thing you check?
Pass signal: Thinks about data drift, embedding model changes, and usage patterns. Does not assume it is a code bug.
6Exec / final interview

The final 45-minute conversation

At this stage you are validating culture fit, long-term trajectory, and checking whether this person will represent your company well to customers. Keep it conversational.

Question 14
What do you think is the most underrated skill for an FDE that nobody talks about in job postings?
Tests self-awareness and whether they have thought seriously about the craft of FDE work.
Pass signal: Says something specific and non-obvious. Common strong answers: patience, managing expectations upward, documentation, or knowing when to say no.
Question 15
Where do you want to be in 3 years? And is this FDE role a step toward that or a destination?
Checks for retention risk and alignment. FDE roles have high burnout. Someone who wants to be a pure IC or move into product in 12 months is a risk.
Pass signal: Sees FDE as a craft not a waypoint. Or if it is a step, has a realistic multi-year view of when that transition makes sense.
Question 16
What questions do you have for me about our customers, our product, or how we think about FDE work?
The best candidates will have done real research and have specific questions. Generic questions here are a yellow flag.
Pass signal: Asks about a specific customer segment, a technical constraint in your product, or how you measure FDE success internally.
Questions 17 through 32 — role-specific deep dives

If your stack is Python-heavy

Ask them to walk through how they would structure a LangChain pipeline for a multi-step customer workflow. Evaluate whether they think about error handling and logging from the start or as an afterthought.

If your customers are in fintech or healthcare

Ask how they have handled data privacy constraints in a customer environment. FDEs in regulated industries need to think about compliance as a first-class concern, not a legal team problem.

If you have a fast-moving product roadmap

Ask how they have communicated a breaking change to a customer whose custom integration depended on an old API. How much notice, what format, and who did they loop in?

If remote collaboration is critical

Ask what their async communication standards are. The best FDEs over-document. Ask them to show you a sample Loom, Notion page, or Slack thread they are proud of.

7Reference check script

The reference call that actually tells you something

Call two references. One former manager and one former customer or customer-facing teammate. Do not accept written references only.

Opening frame: Say you are not looking for a performance review. You want to understand how this person works so you can set them up for success. This gets you more honest answers because references feel less like they are evaluating the candidate and more like they are advising you.

Questions for the former manager
Q1
Can you describe a situation where they had to push back on a customer request that would have caused problems internally? How did they handle it?
Q2
On a scale of 1 to 10, how much did customers ask specifically for them by name? What drove that?
Q3
What is the one thing you would coach them on that would make them significantly more effective in an FDE role?
Questions for the customer contact
Q4
When something broke in your environment, how did they communicate with you? Were they proactive or did you usually have to ask?
Q5
Did you ever feel like they over-promised technically? How did they handle it when expectations were not met?
Q6
Would you hire them directly if you had the budget and the role? Why or why not?
Listen for: Hesitation before "yes" is normal. Immediate enthusiastic yes is a strong signal. Pivot to "well, it depends on the role" with no follow-up is a soft no.
8Offer + scorecard

Salary benchmarks and the weighted scorecard

LATAM FDE salaries vary by country, seniority, and English fluency. These ranges are based on LatamCent placements from the past 12 months. All figures in USD per month.

LATAM FDE monthly salary bands (USD)
