At One Span, we specialize in digital identity and anti-fraud solutions that create exceptional and secure experiences.
We're looking for an engineer who is genuinely on top of agentic AI – someone who believes agents can take over work that today ties up whole people, and who can prove it inside real engineering teams.
This is a founding role.
You'll embed with our R your job is to make them much more productive without adding to their plate.
Do this well and you'll grow it into a small team you lead.
Here is a little taste of your challenge: • Embed and find the work worth removing: Shadow our R reach for a script, pipeline or bit of tooling where that's simply more reliable.
A simple, dependable solution is worth more than a clever one that breaks.
Build for handover, so the team can own it: You build with the team, not for them – and because each team owns its automations after handover, you design them to be owned: documented, monitored where it matters, and maintainable by a normal engineer on that team.
A handover isn't "here's a tool," it's "here's something your team can run and improve without me."
That's also how automations earn trust – they have to be robust enough that teams rely on them and make fewer manual mistakes, not more.
Set the standard, then grow the team:



You're the first hire and the template for everyone who follows.
As the work justifies it, you'll have the chance to lead a small (2–3 person) team focused entirely on AI adoption across R the time you give back to them is your product.
Leadership is upside, not a requirement: If you want to grow into leading the team, great.
If you'd rather stay hands-on and deep, also great.
Fluent in English (essential); Spanish is highly valued for working day-to-day with our Barcelona-based teams.
Practically Speaking, what's in it for you: • A rare greenfield mandate – you define how a whole organization adopts agentic AI, starting from a blank page.
Freedom to bring the right tools – you'll start from our current stack (Claude, our core languages and tooling) and have real latitude to introduce whatever works better.
Teams who want this – the managers are asking for the help and are ready to work with you.
Simplicity – because we like to make things easy and practical.
Beautiful office in the heart of Barcelona – with regular team events (breakfast, lunch...).
Good transport connections – easy to reach by public transport.
Adaptable working hours
