Software Engineer Tech

Barcelona HQ — Hybrid (Tues & Thurs in the office)

We’re a tiny but mighty team of senior technologists and operators, building the product we always wished existed. ai , AI isn’t a bolt-on, it’s the foundation. Every product decision, technical choice, and operational process is designed with AI in mind, which means we build faster, smarter, and very differently from traditional tech companies.

You’ll move between prompt design, fine-tuning, model selection, eval framework building, and production deployment , often in the same week. Own the AI pipeline end-to-end : from prompt design to model deployment, making sure every step is measurable, reproducible, and production-ready.

Curate and generate datasets for training, testing, and benchmarking, including building the tooling to automate this.

You’ll love it here if you…

AI excites you because it’s transformative, not just trendy.

5+ years in software engineering, ideally including time in a seed or Series‑A startup.

Speak Python fluently: Django a big plus.

Picking up new skills or tools regularly feels more like a chore than an opportunity.

You struggle to let go of a project until it’s absolutely flawless.

Familiarity with hybrid model setups — mixing self‑hosted and provider‑based.

Contributions to open‑source AI projects.

Hybrid rhythm: It’s the best of both worlds: deep focus time plus high‑value in‑person collaboration.

Small, senior, sharp: Fewer than 10 engineers, all senior. We build fast, make decisions on data and user impact, and give feedback the way we’d want to receive it: clear, objective, and aimed at making the work better.

90K base salary: competitive for early‑stage, senior‑level roles in Barcelona.

Private health insurance: because your well‑being matters as much as your work.

Portfolio review — If you have GitHub or other public work, we’d love to see it.

Use AI if it helps — we encourage it.

Values interview — 15 mins casual chat with two team members, then 30 min with a co‑CEO.
