Staff L6 | €83,000 – €93,000 + equity | Hybrid in Barcelona

You’ve mastered backend engineering, and now you want to shape systems, guide teams, and influence how things are built across an entire platform.

At bsport, that’s the kind of role we’re offering.

You’ll take the technical lead in one of our product verticals, working on a platform used by >10 million users in >30 countries. You’ll go beyond delivering features; this role is about driving architecture, leading large-scale projects, and helping the whole engineering org grow and mature.

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

Some of the problems you might tackle:

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

You’ll work closely with product, data, leadership, and CTO to make high-leverage 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.

We recently raised a €30M Series B and are aiming to triple our valuation in 2 years. Your equity package is meaningful, and you’ll be in a position to shape both the product and the team as we scale across Europe and beyond.

You might be a great fit if:

You’ve led backend architecture and made decisions that shaped how others design, build, and scale.
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 learn new stacks.

What you’ll get:

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