Mid Backend Software Engineer - FMIT Technologies S.L.
Location:

Málaga, Andalucía (Hybrid)

Type:

Full-time
You don't need someone reviewing every line before it ships, you need the ownership, and a stack worth owning. That's this role.
About FMIT

Ready for a new challenge? Join FMIT, a leader in cutting-edge software solutions, as we expand our backend engineering team. Contribute directly to our success, work on systems that actually matter to our clients, and enjoy the flexibility of a hybrid work model at our headquarters in Málaga.
The Role

As a Mid Backend Software Engineer, you'll independently design, build, and optimize backend systems, not just implement tickets. You'll help shape scalable architecture, keep code quality high, and act as a technical reference point for junior engineers on the team. This is a role for someone who's past needing guardrails and ready to help set them for others.

Design scalable backend systems with maintainability and performance in mind.




Contribute to the development and improvement of CI/CD pipelines.
Develop unit tests and automate workflows to keep code quality high.
Act as a technical reference for junior engineers --- guidance, not hand-holding.
Document backend systems so the whole team can build on them, not just you.
Collaborate cross-functionally to improve APIs and database systems.
What We're Looking For (Must-Have)

Professional experience with JavaScript, TypeScript, and Python, implementing real business logic autonomously.
Solid hands‑on experience with Express, FastAPI, or Fastify, and designing scalable backend services.
Strong PostgreSQL skills, schema design, query optimization, data integrity.
Experience with Kafka or similar for asynchronous, service-to-service communication.
Comfortable working across dev, staging, and production environments.
You write clean, testable code, and you're just as comfortable revi
