Our Mission
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: React Native Engineer
We are looking for a React Native Engineer to join Spiko's engineering team.
You will own the architecture and delivery of our mobile experience and help us ship a best-in-class native app for our retail and B2B customers. Mobile is becoming a strategic surface for Spiko, and you will be the senior IC driving it forward.

Our hiring process
At Spiko, we hire for what you can bring - your skills, your judgment, your drive - not for what you look like, where you come from, or what your background is. We're committed to building a team that reflects the breadth of the customers we serve, and to creating an environment where everyone can do their best work. If something in this job description doesn't match your background perfectly but you believe you'd thrive in the role, we encourage you to apply anyway. Tell us why.
