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. 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), PostgreSQL, TypeScript / Vue.js, AWS.
What They’re Looking For - ~4–6+ years of professional software engineering experience. ~ Strong production-grade Python. ~ Experience building scalable backend systems. ~ Product mindset - thinking beyond implementation. ~ 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.
Why Join - ~ 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. ~ 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.
