Senior Python Engineer | Full Stack | Real-time Data Platform
3 days onsite (nr Oxford) every 6 weeks
This is a backend-led full stack role at an early stage technology company building a production grade SaaS platform for real-time data systems and analytics at scale. This is product engineering, not data pipeline work. You will be building customer facing software that runs in production and is used daily by real users.
The team is growing fast and the scope is broadening. You will work on customer driven features and also contribute directly to the core platform as the business accelerates through its next phase of growth.
You will work primarily in Python, reaching into React on the frontend and working across AWS to ship and support full features end to end.
What you will be doing
- Building backend services and APIs in Python that power customer facing product features
- Working into React on the frontend to complete features across the stack
- Using AWS to deploy, support, and evolve production capabilities
- Contributing to the core platform as the product matures, not just the features built on top of it
- Collaborating with architecture and platform teams to maintain coherence and quality at pace
- Taking ownership of reliability, performance, and maintainability in a live SaaS environment
What we are looking for
- 5 or more years building production SaaS systems as a Software Engineer, with a backend focus
- Strong Python fundamentals with real production experience in a SaaS context
- Working ability in React or frontend development more broadly
- Cloud experience, ideally AWS
- Comfortable in early stage environments where ownership is high and things move fast
- A production first mindset with a strong sense of software quality
Nice to haves
- Experience in data intensive or real-time systems
- Exposure to API driven architectures and event driven patterns
- Previous work on multi-tenant SaaS platforms
Salary: £70,000 to £80,000 plus benefits
Applicants must already be based in the UK and eligible for SC security clearance (min of 5 years working in the UK)
Interested? Drop me a message and I will share more context on the business and the platform.
