The role

Most AI tools in finance stop at conversational dashboards and CFO co-pilots that summarize reports. This London-based fintech, backed by top-tier venture funds, is building an autonomous digital worker that actually executes across banking rails, FX, liquidity, and reconciliation.

You will join as a founding-team Product Engineer working directly with the founders to turn prototypes into resilient, production-grade infrastructure. This is end-to-end full-stack ownership with a direct path to engineering leadership as the team scales, not a narrow seat where you push tickets down an assembly line.

The work

• Architect and ship core product features across backend and frontend, integrating directly with banking rails, protocols, and financial tools.
• Design fault-tolerant, scalable architectures handling real-money movement, automated payments, and multi-currency reconciliation.
• Establish the testing, monitoring, and CI/CD foundations that let a tight team deploy to production quickly and safely.
• Collaborate closely with founders, commercial teams, and customers to discover requirements and rapidly iterate on production features.
• Help shape engineering culture and onboard future hires as the team grows, setting yourself up to step into an engineering lead role.

What You Bring

• 3+ years of software engineering experience with strong foundations in backend systems, database architecture, and service-oriented design.
• Demonstrated experience in fintech, banking infrastructure, or payment rails; Open Banking familiarity is a strong advantage.
• A bias for high-velocity iteration combined with the discipline needed to build fault-tolerant financial systems where correctness is non-negotiable.
• High comfort with early-stage ambiguity and a founder mentality; you talk directly to customers and solve the business problem, not just the ticket.
• Based in or able to commute to London.

Why apply through Dex

Early-stage founding seats at well-backed fintechs are rarely surfaced clearly, and distinguishing real infrastructure from generic AI hype is difficult from a standard job spec. Dex screens the company and the architecture for you, skips the cold-application queue, and gets you straight into high-context conversations with the founders. Sign up once to unlock this seat and other high-conviction technical roles across London.
