Senior Backend Engineer, Barcelona

Barcelona, Barcelona, España bsport A tiempo completo 73.000 € - 93.000 €

Already living in Barcelona or Paris? Or ready to relocate?

When to apply? You've mastered backend engineering and are now ready to shape systems, guide teams, and influence how things are built across an entire platform.

We recently secured a €30M Series B, and our goal is to triple our valuation within two years — making your equity package highly relevant. The engineering team is set to double this year, making it the perfect time to step in, leave your mark, and grow into a leadership or staff role as the team expands.

You'll take technical ownership of one of our product verticals, working on a platform used by over 10 million users in more than 30 countries. This role goes beyond delivering features — it's about driving architecture, leading large-scale projects, and helping the entire engineering organization grow and mature.

Our stack includes Python, Django/FastAPI, React, AWS, and Kubernetes, but we hire language-agnostic engineers who care more about strong engineering principles than specific tools. If you've led the design and delivery of scalable backend platforms in any object-oriented language, we want to talk.

Some of the challenges you might tackle:

  • Designing the next stage of our modular monolith, helping teams ship faster with greater ownership
  • Scaling multi-region infrastructure with sharded PostgreSQL and distributed services
  • Leading cross-team architecture reviews and improving the foundation of a high-transaction system (~$1M daily volume)
  • Creating frameworks, conventions, and tooling that help engineers move faster with higher quality

You'll work closely with product, data, leadership, and our CTO to make high-impact technical decisions. This is a hands-on leadership role focused on architecture and engineering quality — not people management. You'll mentor software engineers, challenge assumptions, and raise the standard of backend engineering across teams.

You might be a great fit if:

  • You've led backend architecture and made decisions that influenced how others design, build, and scale systems
  • You've guided the work of other engineers through mentorship, coding standards, and technical leadership
  • You have deep experience in product or SaaS scale-ups
  • You're fluent in English and confident in cross-team communication
  • You've worked with Python/Django or are quick to pick up new stacks

What you'll get:

A €73,000–€93,000 salary + equity, a hybrid setup, work-from-anywhere weeks, full health insurance with Alan, and fitness perks like discounted DiR Gym and Yoga One memberships. We also offer relocation packages
