Backend developer recruitment

Backend recruitment focused on production systems, sound data decisions and maintainable service design.

Instruct us

Technical screening by developers and CTOs is included.

Backend developer recruitment with technical depth

We recruit backend engineers across Node.js, Python, Ruby on Rails, C#, .NET Core, PHP and Go. Our technical screening examines API design, data modelling, service boundaries, reliability and the candidate’s ability to work inside a real production environment.

When to hire Backend developers: A backend team adding specialist depth. A platform moving beyond its first architecture. A product with complex integrations or data requirements.

Technologies, requirements and soft skills

Backend titles often hide very different jobs. We clarify the language, data, scale, integration and operational expectations before sourcing begins.

Languages and frameworks

Senior engineers ask candidates to trace request handling, error propagation and concurrency in their chosen runtime, then discuss how they structure code for testing and change.

  • Node.js
  • NestJS
  • Express
  • Python
  • Ruby on Rails
  • C#
  • .NET Core
  • PHP
  • Go

Data

We ask candidates to model a realistic domain, reason about indexes and transaction boundaries, diagnose a slow query and justify relational, document or cache choices.

  • PostgreSQL
  • MySQL
  • SQL Server
  • MongoDB
  • Redis
  • Firebase
  • Supabase

Architecture

We test API contracts, idempotency, queue failure handling and service boundaries by asking how the system behaves during retries, partial outages and schema changes.

  • RESTful APIs
  • Microservices
  • Prisma
  • TypeORM
  • Mongoose
  • BullMQ

Soft skills and working style

We look for engineers who think beyond the immediate ticket, remain calm when production systems fail and make careful changes while communicating contracts and risks clearly to dependent teams.

  • Systems thinking
  • Ownership
  • Careful judgement
  • Incident composure
  • Collaborative API design

How we assess backend engineers

We test engineering judgement in the context of the system the candidate will maintain, scale or help design.

Service design

API contracts, boundaries, failure modes and maintainable application structure.

Data decisions

Schema design, query behaviour, consistency and appropriate storage choices.

Production readiness

Testing, observability, deployment awareness, security and debugging.

What every candidate needs to demonstrate

Tool names are not enough. Across every role, we look for technical depth, disciplined use of AI and an honest approach to solving unfamiliar problems.

Understands what happens behind the scenes

We keep asking why and how until we reach the underlying behaviour. Candidates should understand what their framework, runtime, database, browser, cloud service or design tool is doing for them, how they work behind the scenes (and why), and how they would investigate a failure without relying on copying fixes from ChatGPT.

Uses AI with engineering discipline

We expect candidates to use AI productively, but never as a substitute for judgement. They need to explain how they verify generated code, designs and tests, protect confidential data, catch unsafe assumptions and remain accountable for the result. We expect them to use MCPs, skills, and goals. So basically - we are looking for structured AI-assisted work, not vibe coding, vibe designing or vibe testing.

Combines initiative with honesty

Strong candidates have a can-do mindset and will investigate, experiment and learn when the answer is not obvious. At the same time, they are fair and transparent about what they know, what they have not done before and when they need support.
