Senior Product Engineer

Our Mission Money sitting idle is money lost. We're fixing that. Founded in 2023 by Antoine and Paul-Adrien , Spiko gives SMEs, non-profits, financial advisers and fintechs access to institutional-grade cash management, via app or API. We are building the full infrastructure: issuing, operating, and distributing the products ourselves.

Two years after launch, we serve thousands of organizations across Europe and process hundreds of millions of euros in flows every month. Our ambition: become the world's leading treasury management infrastructure in a market worth trillions. We are backed by Index Ventures, the CEO of Revolut, the founder of Kyriba, and the CTO of Wise.

Spiko runs on excellence, transparency, and straight talk. The role Engineers own product decisions at Spiko. We call this role the Product Engineer : an engineer who owns a feature end to end. You are given a problem to solve and full ownership of how to solve it. You own the scoping, the architecture decisions, the implementation and the production release.

As a Senior Product Engineer, you also own one of Spiko's business areas: you are its main architect and the default reviewer of every PR inside it. You mentor more junior team members and help them grow their skills. More on the role: Introducing Spiko's Product Engineer .
