Get to know us:
Started in 2016, Frekuent is now the all-in-one payment and loyalty platform for unattended environments — 500+ clients, 100M+ transactions a year, 2.5M+ users across Spain, France, Italy, Portugal, and Singapore. We turn one-time buyers into lifetime clients with cashless, contactless, effortless payments: less friction, more reasons to come back.
2026 has been our biggest year yet — we've hyperscaled from 40 to 100+ people, with more hires on the way, and closed a €6M funding round to fuel what's next.
And we're just getting started — our goal is to become the default payment and loyalty layer behind every unattended transaction, everywhere.

Why this role exists:
At Frekuent, we don't build backend systems for their own sake — we build the engine behind products people actually use. You'll join a lean, senior product engineering team where ideas move from a Slack thread to production in days, not quarters, and where every tool at your disposal — including the AI ones we build with daily — is treated as leverage,



not overhead.
If you've outgrown "ticket-taking" backend work and want to be in the room when a feature gets conceived, not just when it gets assigned to you, this is that room.
What you'll actually do:

Own features end-to-end: architecture, implementation, release, and the metrics that tell you whether it worked.
Use AI-assisted development as a default part of your workflow — we optimize for shipping quality code fast, not typing it manually.
Help design and integrate AI-powered features into our product — from LLM-backed workflows to smarter automation — alongside our Product and Data teams.
Do real code review and architectural sparring with people who'll push back on your ideas (and will expect you to push back on theirs).
Hunt down gnarly bugs and turn what you learn into reusable libraries, not tribal knowledge.
Spot scaling and reliability problems before they page anyone at 2am.
