What Is A Backend Developer?

A backend developer builds the APIs, server-side logic, and database architecture that power a product behind the scenes, using languages like Node.js, Python, Java, or Go. They own system reliability and performance, working closely with frontend and DevOps engineers to ship features without breaking what’s already running.

Also called: Back-End Developer, Server-Side Developer
Reports to: Engineering Manager / VP Engineering
Works on: APIs, databases, cloud infrastructure
Measured on: System reliability, API performance

What A Backend Developer Actually Does

01 · APIsBuilds and maintains REST or GraphQL APIs and the business logic behind them
02 · Database DesignDesigns and optimizes the database schema and queries that the application relies on
03 · InfrastructureManages cloud infrastructure and CI/CD pipelines so code ships safely and repeatably
04 · ReliabilityMonitors system performance and hardens security to keep the product reliable at scale
05 · CollaborationPartners with frontend and DevOps engineers to ship end-to-end features without regressions

Backend Developer Vs. Similar Roles

Role	Main focus	Primary metric
Backend Developer	Builds server-side logic, APIs, and databases	System reliability, API performance
Frontend Developer	Builds the user-facing interface and client-side logic	UI performance, user experience
Full-Stack Developer	Works across both the frontend and backend	End-to-end feature delivery
DevOps Engineer	Builds and maintains deployment pipelines and infrastructure	Deployment frequency, system uptime

At smaller companies or early-stage startups, one person often works as a full-stack developer across the whole stack, or a backend developer picks up DevOps work directly. Split into a dedicated backend role once the product and infrastructure are complex enough to need focused ownership.

Skills To Screen For

Strong proficiency in a primary backend language, like Node.js, Python, Java, or Go Experience designing and optimizing relational or NoSQL database schemas Hands-on with cloud infrastructure (AWS, Azure) and CI/CD pipelines Business-level English for cross-functional collaboration with product and frontend teams

Interview Questions Worth Asking

1"Walk me through how you’d design the database schema and API for a new feature from scratch."

2"Tell me about a time a service went down in production. How did you find and fix the root cause?"

3"How do you decide when a slow query is worth optimizing versus leaving alone?"

Bogota, Mexico City, Sao Paulo, and Buenos Aires don’t change their clocks, so the overlap shifts when yours does. Times shown are in your team’s time zone. National English-proficiency averages vary by market too: Argentina ranks in EF’s "High" band globally, while Colombia, Mexico, and Brazil sit in the "Low" band. Screen every candidate’s spoken English directly rather than assuming by country.

Common mistake: hiring a generalist full-stack developer into a dedicated backend seat and expecting deep systems and database expertise. As products scale, backend work increasingly means schema design, query optimization, and infrastructure decisions that a surface-level full-stack background doesn’t prepare someone for.

Frequently Asked Questions

What is the difference between a backend developer and a frontend developer? −

A frontend developer builds the user-facing interface and client-side logic that people interact with directly, and is measured on UI performance and user experience. A backend developer builds the server-side logic, APIs, and databases behind the scenes, and is measured on system reliability and API performance. Many products need both working closely together.

How is a backend developer different from a full-stack developer? +

A full-stack developer works across both the frontend and backend of a product, while a backend developer focuses specifically on server-side logic, APIs, and databases. At smaller companies, one person often covers both; as the product grows, teams usually split the roles so each person can go deeper.

What does a backend developer cost in the US versus Latin America? +

US backend developers average around $135K a year, with typical postings ranging from $98.5K to $142K. Backend developers hired through LatamCent in Latin America average around $54K a year, roughly 60% less, or about $81K in savings per hire.

How long does it take to hire a backend developer through LatamCent? +

Most searches run 21 days from kickoff to a signed offer, with 3 to 5 candidate profiles delivered in the first 10 days.

Can a backend developer in Latin America realistically cover US business hours? +

Yes. Colombia, Mexico, Brazil, and Argentina all sit within a few hours of US time zones, so most teams get 6 to 8 shared working hours a day depending on which US time zone they’re in, enough for stand-ups, code review, and live debugging sessions.
