encord - Senior Full-Stack Engineer, Physical AI
Requirements
• Experienced: you've seen a lot and built a lot — personally developed and maintained multiple systems from scratch, with a deep understanding of the trade-offs involved in building reliable, performant software at speed • At home with challenging frontend work: you're comfortable rendering complex 3D scenes, working with spatial and sensor data, and optimising for browser performance • Impact-driven: you want your work to have a tangible outcome for people and aren't satisfied by products that don't see the light of day • A builder: you enjoy all aspects of building a complete product, are comfortable moving across the stack, and love problem-solving from first principles • Comfortable with uncertainty: happy to tackle problems without a predefined solution, and excited to make decisions autonomously as you go • A team player: you contribute your best work and actively help others do the same — you enjoy levelling up those around you • Strong full-stack engineering experience, with a particular strength in complex, high-performance frontend work • Experience with 3D rendering, WebGL, or similar technologies for visualising spatial/sensor data is a strong plus • Proficiency in Python and/or TypeScript; experience with React a plus • Familiarity with cloud infrastructure (GCP preferred) and containerised deployment (Kubernetes) • Experience in robotics, autonomous vehicles, or Physical AI is a plus • We are technology agnostic at Encord and not looking for experience across all of these — as long as you're open to learning, please apply. • Backend: Python • Frontend: TypeScript and React • Deployment: Kubernetes • Infrastructure: GCP • Machine learning: PyTorch, CUDA, Ray
Responsibilities
• Build and maintain high-performance frontend experiences, including rendering complex 3D scenes with thousands of objects at smooth frame rates • Work across the full stack — from backend data pipelines and storage systems to frontend visualisation and interaction • Take end-to-end ownership of projects, from product and architectural decisions through to deployment, monitoring, and measuring user impact • Work with visual, spatial, and sensor data to make sense of the physical world • Tackle complex domains at massive scale using simple, well-crafted solutions • Take initiative, be proactive in problem-solving, and continuously seek improvements
Benefits
• Competitive salary, commission, and meaningful equity in a high-growth startup • Strong in-person culture — most of the team works from our London office 4+ days/week • 25 days annual leave + UK public holidays • Annual learning & development budget • Travel for customer visits, events, and conferences across the UK and Europe • Company lunches twice a week • Monthly socials & bi-annual team offsites
