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 • Excited by hard frontend challenges: rendering complex scenes, working across data modalities, and squeezing performance out of the browser • 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 frontend engineering experience, with production-grade work on complex, high-performance UIs • Proficiency in TypeScript and React • Experience with 3D rendering, WebGL, Canvas, or similar browser-based visualisation technologies is a strong plus • Familiarity with Python and backend development • Experience with Kubernetes and GCP 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 and Rust • Frontend: TypeScript and React • Deployment: Kubernetes • Infrastructure: GCP
Responsibilities
• Build and own complex UI and editor interfaces for visualising and annotating multi-modal data • Render high-performance 3D/4D scenes with thousands of objects in the browser • Work across the full stack when needed, from backend services to deployment and styling • Take end-to-end ownership of projects, from product and architectural decisions through to deployment, monitoring, and measuring user impact • Collaborate closely with a lean, high-trust team to tackle challenging problems together • 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 • We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
