Senior Product Engineer

Senior Product Engineer - Python / Product - UK, Remote

Are you the kind of engineer who wants to design systems and shape products, not just pick up tickets?

We’re hiring a Senior Product Engineer into a small, remote-first team that owns the “supply” side of a research platform.

What you’ll be doing:

This isn’t a “sit in the corner and code what you’re given” role.

You’ll be:

• Working hands-on across backend (Python) and frontend
• Designing and explaining systems end-to-end (high-level diagrams, data flows, trade-offs)
• Dealing with a large monolith that’s being modularised and improved
• Solving core problems like:
• how experts get onto the platform without long waitlists
• how the right people see the right things at the right time
• Pairing with Product to shape scope, priorities, and “what good looks like”
• Using data and real user feedback to decide what to do next

There’s a lot of thinking, not just implementing.

What they care about:

Yes, they want a strong Python engineer.

But more importantly, they want someone who:

• Thinks in systems, not just tickets
• Can explain why they made certain technical decisions
• Cares about business and customer impact, not just code quality
• Pulls their weight in a small, high-trust, fully-remote team

On the technical side, you’ll need:

• Solid Python experience building non-trivial backend systems
• Willingness to work full stack:
• Vue is ideal, or strong modern JS framework + appetite to learn Vue
• Comfort with cloud (GCP preferred; AWS is fine if fundamentals are strong)
• Experience with larger/evolving codebases (monolith experience is a plus)
• Ability to sketch and talk through system designs and trade-offs

You don’t have to know everything. But you do need to be senior in Python and able to own problems end-to-end.

Why this is worth a look:

Most roles are “build this feature in your lane”.

This isn’t.

• You’ll have real ownership in a critical part of the platform (participant supply & distribution)
• You’ll work across design, code, and product decisions – not just one layer
• You’ll do it fully remote, anywhere in the UK, with a team that actually cares about engineering quality and people

If you’re a strong Python engineer who enjoys full-stack work, systems design, and real product impact, this is the kind of role where you can actually shape how things work.
