Senior Engineer (Software)

Forward Deployed Engineer | London | £135k

Our client is building real-time intelligence from sensor data, no new hardware needed. Privacy-first, fast-growing, and with significant investment and new client pipeline.

They are looking for a Founding Engineer or Founding Product Engineer to join their team to work with the customers to identify what they actually need and then build the product and collaborate with the other technology teams to deliver. This role is suitable for a technologist who has worked in a start-up, with strong engineering capabilities, but can talk to non-technical humans without alienating them with technical jargon.

What you'll be doing

Onsite with customers 1-2 days a week, figuring out what they actually need (not just what they say they need). Then building it: data pipelines, backend services, UI, sometimes hardware config. Python, Rust, TypeScript, Linux. Right tool for the job.

Requirements

• Strong backend engineering skills - Python/ React preferred
• Founding engineer or founding product engineer energy. You've built things from scratch and dealt with the mess that comes with it
• Can talk to non-technical people without losing them
• Has worked directly with customers
• STEM background from Russell Group or top university

Nice to have

• PM or team lead experience
• ML/data science exposure
• React/TypeScript frontend, backend services
• Interested in working across cloud, bare metal, embedded, containers, GPU

What is in it for you?

Early-stage, high-impact, genuinely good people doing genuinely good work. It's chaotic. It's not for everyone. But if you want real influence over how an engineering team gets built from the ground up, this is for you.
