Senior SDET

Total package - £80,000 (equity bonus)

Location: London 3 days a week

This isn’t a ticket-closing automation role.

This isn’t a ‘put your headphones in and work in silence on your own all day’ role

This is definitely not a ‘hold my hand / tell me what I should do’ role

We're looking for a Senior QA / SDET who wants to lead from the front... someone who still loves solving technical problems but is ready to mentor 3 - 4 engineers and shape how quality is delivered across a growing product team.

You’ll be joining a scaling, product-led tech business (c.100 people in UK, 600 globally) where engineering, product and QA collaborate closely to deliver features quickly and properly.

There’s a real opportunity to raise standards, introduce better practices, and influence direction over the next 6–12 months.

What you’ll do

  • Alongside QE Manager, deliver automation strategy within a product area
  • Write high-quality automation code (Python or TypeScript)
  • Work across backend APIs (REST, ideally GraphQL exposure)
  • Line manage 3 - 4 QAs (light-touch mentoring & performance reviews)
  • Partner with Product & Engineering to improve release quality
  • Build tools or frameworks where gaps exist

What they’re looking for

  • Strong coding ability (Python or TypeScript essential)
  • Automation-first mindset (Playwright a plus, not essential)
  • Confident working with APIs & backend systems
  • Experience mentoring or line managing engineers
  • Someone proactive, not reactive
  • Comfortable challenging constructively and driving improvement

This would suit:

  • A Senior SDET ready to step into team leadership
  • A hands-on QA Lead who still wants to code
  • Someone who cares about product outcomes, not just test coverage

Key priority hire with interview availability as soon as this week. Please apply ASAP. No sponsorship.
