Job Description:

Founding Engineer / Technical Lead London · £160,000 + equity + bonus

I’m recruiting for an early-stage mobility infrastructure business that is quietly building something significant at the intersection of payments, vehicle telematics, and location intelligence.

This is the first engineering hire (employee number one on the technical side) working directly alongside the founder to take the product from its current state to a fully built, scalable platform.

What you’ll be building

  • The MVP and core product, from first principles
  • A geospatial decision engine that detects when vehicles enter chargeable zones in real time
  • Integrations with telematics providers, OEM APIs, and payment systems
  • Billing and payment orchestration infrastructure
  • Scalable backend services and APIs that will form the foundation of the business

What you’ll own

  • All major technical decisions (architecture, stack, tooling, standards)
  • The engineering culture and hiring process as the team grows around you
  • A direct line to the founder and full visibility of the commercial roadmap

What they’re looking for

  • A strong backend engineer who has built production systems at scale
  • Someone who has built a product end to end (from the ground up) + helped scale an engineering team (defined a stack/ made key decisions/ defined architecture)
  • Someone who is happy to be hands on at first + grow a team out over time
  • Experience in one or more of: fintech/payments, geospatial systems, fleet/telematics, or mobility
  • Someone comfortable making technical decisions with limited information and limited resources
  • An ownership mentality – this is a zero-to-one role, not an execution role

Stack pointers

Python, TypeScript, Go or similar · AWS · PostgreSQL · REST APIs · Docker/CI/CD – You will define the stack

About the role

  • Funded and in market -this is a real business with real traction, not a pre-revenue concept
  • Meaningful equity from day one
  • Full autonomy to make technical decisions and grow the engineering team in your own image
  • The founder has previously built and exited a company in the mobility space
  • London-based with a permanent office in the works

£160,000 + equity + bonus · London

If this sounds like the right next move, get in touch in confidence.
