The Company - AI systems are only as reliable as the data and feedback loops behind them. We’re partnering with a profitable, globally-used technology company building infrastructure that helps global organisations develop more reliable, trustworthy AI systems. Their platform supports teams working across research, healthcare, and enterprise environments - where accuracy, integrity, and real-world performance genuinely matter. The business has been operating successfully for over a decade and is now scaling rapidly due to accelerating demand in AI. With strong product-market fit and significant growth ahead, they’re investing heavily in senior engineering talent to shape the next phase of the platform.
The Role - You’ll join a senior, product-focused engineering team working in small high performance teams building high-scale backend systems that sit at the core of the company’s platform. This is a backend-first role (Python ≈70%) with meaningful influence across system design, architecture, and product direction. You’ll operate with real ownership - balancing delivery speed, scalability, and long-term maintainability - while contributing to a platform that underpins critical AI-driven applications globally.
What You’ll Be Doing - Designing and owning backend services in Python (Django / FastAPI), building scalable APIs and workflows supporting global usage, improving reliability, performance, and developer experience, working closely with Product and Design to shape features end-to-end, contributing across the stack when useful (TypeScript exposure), helping evolve engineering standards as the team scales. This is a pragmatic, fast-moving Product Engineering centric environment - but with a strong emphasis on thoughtful engineering.
Tech Stack - Python (Django core), FastAPI (in parts), PostgreSQL, TypeScript / Vue.js, AWS, Modern CI/CD practices.
What They’re Looking For - 4–6+ years of professional software engineering experience, strong production-grade Python, experience building scalable backend systems, comfort operating with ambiguity and ownership, product mindset - thinking beyond implementation, clear communicator, collaborative by nature, experience in startup or scale-up environments preferred, no degree requirements, exposure to AI systems, research platforms, or data-intensive products is a bonus — not required.
Interview Process - 30-minute intro (Engineering & Talent), 60-minute collaborative Python pairing session, product & architecture discussion, final conversation with senior leadership. Structured, respectful, and focused on real-world thinking.
Why Join - Globally used platform with strong product-market fit, direct impact on how modern AI-enabled systems perform in the real world, senior hiring bar - high quality, low ego, fully remote within the UK, with a London office, engineering team scaling from ~60 → 100+, £80–100k base + bonus + equity, strong benefits package. If you’re a senior Python engineer who enjoys building robust, high-scale systems and wants your work to contribute to more reliable, real-world AI applications - this is a genuinely meaningful opportunity. Apply with your CV and we’ll be in touch if there’s alignment :)
