Backend Engineer

Barcelona, Spain

You will 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!
