Hire Backend Engineers

Why Hiring Backend Engineers Requires Technical Depth

Backend engineering is the foundation every application runs on, yet it is invisible to most non-technical stakeholders involved in hiring. The difference between a junior developer who can write CRUD endpoints and a senior backend engineer who designs fault-tolerant, scalable systems is enormous — but nearly impossible to detect from a resume or behavioral interview alone.

The backend landscape has exploded in complexity. Modern backend engineers must navigate microservices vs. monolith trade-offs, choose appropriate database technologies, implement authentication and authorization correctly, design APIs that are both flexible and performant, and handle concurrency, caching, and distributed system challenges. A recruiter without engineering experience simply cannot evaluate this range of skills.

Exodata's engineers conduct live assessments that go beyond coding exercises. We evaluate system design thinking, database modeling decisions, API contract design, and how candidates handle real-world scenarios like scaling bottlenecks, data consistency challenges, and service-to-service communication patterns. You get candidates who can actually build the systems your business depends on.

What Our Engineers Assess

Every backend engineer candidate goes through a live technical assessment with our engineering team. Here's what we evaluate:

• API design — RESTful best practices, GraphQL schema modeling, versioning strategies, pagination, and rate limiting
• Database architecture — relational modeling, indexing strategies, query optimization, and data migration patterns
• Microservices patterns — service decomposition, inter-service communication (sync/async), event-driven architecture, and saga patterns
• Concurrency and performance — thread safety, connection pooling, caching layers (Redis, Memcached), and load handling
• Security fundamentals — input validation, SQL injection prevention, OAuth/JWT implementation, and secrets management
• Testing and reliability — unit testing, integration testing, contract testing, graceful degradation, and circuit breaker patterns
