Job description

Senior Software Engineer | London | £80,000 - £150,000 | Python | React

Location: London-based (hybrid)

Salary: £80,000 - £150,000 + equity

Tech Stack:

• Backend: Python (Flask, FastAPI) - backend weighted
• Frontend: React, TypeScript
• Cloud Systems: GCP or AWS

Are you a software engineer who enjoys shipping real products, solving tangible customer problems, and seeing your work in production quickly?

We are working with a Series A AI technology company building automation software that sits directly in the operational core of key businesses. This is not experimental AI. This is production critical software used daily by hundreds of customers.

This is a hands on individual contributor role suited to engineers who want ownership, pace, and impact without layers of process getting in the way.

What you will be doing:

• Designing, building, and maintaining backend services and APIs using Flask & FastAPI
• Building and evolving user facing web components using React/TypeScript
• Integrating third party services and AI models into production workflows
• Investigating production issues and contributing to root cause analysis
• Collaborating closely with product, operations, and non technical stakeholders
• Participating in code reviews and shaping engineering standards

What they are looking for:

• Someone who genuinely enjoys building and shipping software frequently
• Strong problem solving ability with a pragmatic engineering mindset
• Comfort owning features end to end from build through deployment
• A bias to action while still caring about scalability and reliability
• Ability to work across the stack or depth in one area with curiosity in others
• Experience with Python based backend systems and modern frontend frameworks

They value engineers who focus on outcomes over perfection, who simplify rather than over engineer, and who take responsibility rather than waiting for instruction.

What you can expect:

• Meaningful equity
• London based role (hybrid) with regular in person collaboration & opportunities for international travel
• Extensive company benefits

This role will suit engineers who want to work close to the product, close to customers, and close to real world impact. If you're looking for ownership, pace, and meaningful software problems, then get in touch at imogen@sr2rec.co.uk.
