The role
This team is building a regulated financial institution from first principles. Their mission: bank and finance the companies driving Europe's defence, security, and resilience buildout. A trillion-euro market is opening up as strategic autonomy becomes a priority, and traditional banks aren't built for the startups at its core. They are backed by leading investors.
As the founding engineer, you'll own the entire technical stack from day one. This means architecting, building, and securing the core platform, taking the initial product from concept to production. This is a hands-on building role, not a management position. You'll set the engineering culture and help scale the team, working directly with the founder to translate ambitious ideas into robust, regulated systems.
The work
- Architect, build, and secure the entire core banking platform from first principles.
- Own all technical decisions: infrastructure, backend systems, data integrity, and product engineering.
- Translate complex regulatory requirements into scalable, resilient, and compliant financial systems.
- Drive the product from initial concept through to production, ensuring security and reliability.
- Define the engineering culture and recruit the foundational engineering team.
What You Bring
- 5-12 years of engineering experience, with deep expertise in backend systems, infrastructure, and production architecture.
- Proven track record building complex, highly regulated financial infrastructure (e.g., core banking, ledger systems, payments).
- Experience as a founding engineer, early hire, or senior engineer scaling a high-growth fintech or infrastructure company.
- Expertise in distributed systems, cloud infrastructure, data integrity, reliability, and security.
- London-based or willing to relocate, and committed to in-person collaboration.
