Descripción del empleo

This role is with one of Dex's trusted partner companies. We work closely with their teams to truly understand their culture, goals, and what they're looking for, so we can match you with the right opportunity and give you context about the role before you commit to a process.

The role

An early-stage fintech backed by leading European investors with roughly $8M in funding is putting corporate treasury and finance operations on autopilot. Their platform connects fragmented banking rails and modern software tools to automate payments, FX, liquidity, and reconciliation through applied AI. Operating out of London with a tight team of around a dozen people, they are stripping the manual friction out of how growing businesses move and manage capital.

You will join the founding engineering team as the CTO's right hand. Your mandate spans shaping the technical roadmap alongside the founders, speaking directly with customers, and shipping production code end to end, often on the same afternoon. This is not a compartmentalised feature-factory role where tickets are handed down from product managers, nor is it a detached management post away from the codebase. It is a high-leverage seat for an engineer who wants direct ownership over architecture, user experience, and core financial infrastructure.

The work

• Partner directly with the CTO and founders to prioritize the project portfolio, define technical requirements, and shape the core product roadmap.
• Own features end to end across the full stack in TypeScript and Node.js, from database schema design and backend service logic to frontend UX and deployment infrastructure.
• Engage directly with commercial customers and banking partners to diagnose complex operational bottlenecks before writing code.
• Set engineering standards, run QA, unblock teammates across the stack, and iterate continuously on live production workflows based on real customer feedback.

What You Bring

• 7 to 10 years of full-stack engineering experience, actively building and shipping production systems in TypeScript and Node.js today.
• Demonstrated track record of end-to-end product ownership, taking complex workflows from ambiguous customer problems through architecture, delivery, QA, and iteration.
• Founder DNA or early-stage startup experience, thriving in high-velocity environments where engineers scope their own work and interface directly with customers and partners.
• London-based or able to work from London (visa sponsorship is available).
