Senior Software Engineer – Platform

📍 UK or Ireland | Remote-first | £100K – £120K + equity

We’re hiring a Senior Software Engineer to join my clients Platform team at a fast-growing, Series C backed developer tools company – trusted by some of the most demanding engineering organisations in the world to protect and accelerate their software delivery.

This isn’t a role where you own one service and sit in a lane. You’ll be working across the full stack – from AWS infrastructure through to backend application code – solving problems that span service boundaries and don’t always have a clear path forward. One week you’re diagnosing a performance regression for an enterprise customer, the next you’re rethinking how authentication or billing works at scale.

What the work looks like

• Building and shipping platform features and optimisations that matter at global scale
• Keeping systems fast, reliable, and running smoothly across a distributed architecture
• Working closely with product, design, and customer success to solve real problems
• Raising engineering standards through testing, code review, and mentoring
• Owning problems end to end, not just handing off tickets

The stack

Python, Django, AWS (ECS, Lambda, CloudFront, Kinesis), Postgres, Terrafrom, Celery, Clickhouse, Flink, Elasticsearch, CircleCI

What we’re looking for

• 5+ years building and operating complex distributed systems in production
• Strong Python background, ideally with Django
• Comfortable across AWS infrastructure and IaC (Terraform)
• Experience with event-driven architectures and high-volume data pipelines
• Someone who thrives in ambiguity and moves with confidence
• Based in the UK or Ireland with the right to work independently

Why us

• Small, senior team – what you say actually changes things
• Deploying multiple times a day, modern CI/CD, no bureaucracy
• Competitive salary, equity, health insurance, generous leave, professional development budget
• Regular team gatherings and engineering days, fully remote otherwise
• On a trajectory toward IPO and beyond – now is a genuinely exciting time to join

If you’re the kind of engineer who gravitates toward the hard problems underneath the product and wants to work somewhere that genuinely cares about doing things properly – we’d love to hear from you.
