The role owns features end to end, primarily across frontend applications for scientific workflows, while also contributing to backend services, APIs, data models, and quality practices.\n\nResponsibilities\nOwn a feature end to end: scope it with product and design, build it across the stack, and ship it\nTurn research workflows into intuitive, performant interfaces, working closely with product managers and designers\nBuild and maintain complex, data-rich web applications in Svelte and SvelteKit, implementing high-fidelity designs from Figma with meticulous attention to detail\nCreate data visualizations that help scientists explore and interpret experimental results\nArchitect performant frontend systems that handle async data loading, real-time reactivity, and large-scale state management\nDesign AI-agent experiences (tool calls, streaming responses) that fit into real scientific workflows\nExtend Cortex, our Go backend, with new RPC endpoints and business logic, including server-streaming endpoints that push live lab state to the UI as experiments run\nDesign and evolve the protobuf schemas that define the contract between the backend and every client, keeping changes backward compatible as generated code lands in TypeScript, Go, and Python\nModel and update data in MongoDB: document schemas, indexes, and versioned migrations run against production data\nWrite automated tests on both sides of the API and contribute to CI/CD pipelines\nUse user feedback, usage, and performance data to decide, with product managers, what to improve next\n\nSkills\nAt least 5 years of professional experience with TypeScript, HTML, and CSS (ideally Tailwind), with a solid grasp of responsive and mobile-first design\nStrong experience with modern frontend frameworks and reactive state management (Svelte/SvelteKit preferred; React or Vue acceptable if eager to learn Svelte)\nComfortable with modern build tooling (Vite, ESBuild, Rollup), Node.js, debugging, and performant frontend architecture (async data loading, security, Sentry)\nHands-on data visualization experience, ideally with D3 or low-level SVG/canvas graphics for custom scientific charts\nDemonstrated product sense: you've shipped user-facing features, made scope and tradeoff calls, and can explain why you built something the way you did\nProfessional experience writing server-side code in a statically typed, compiled language (Go preferred; Java, C#, Rust, or C++ acceptable)\nExperience designing and evolving API contracts (gRPC and Protocol Buffers preferred; REST or GraphQL acceptable)\nWorking knowledge of databases, data modeling, index query performance, and running production data migrations (MongoDB or document stores preferred)\nClear, precise communicator, especially when working across disciplines\nExperience working directly with users or stakeholders to shape requirements\nComfortable operating without a hard frontend/backend boundary: you pick up whichever layer the feature needs, and you know when to pull in a specialist\nWe actively use AI-assisted development and expect engineers to find their own productive workflows with these tools\nStrong performance mindset: rendering large datasets without dropping frames, canvas-backed charts, virtualized tables and lists, or moving compute off the main thread with Web Workers\nFamiliarity with agentic systems (prompting, tool calls, MCP) or AI-frontend integration (e.g. Vercel AI SDK)\nExperience delivering real-time data to clients: server-streaming RPCs, WebSockets, SSE, or database change streams\nTesting experience: Playwright, Vitest, API mocking, linters, and formatters\nObservability practice: OpenTelemetry traces, metrics, and structured logs, or an equivalent\nAdvanced browser APIs such as the History API and structured concurrency in the browser\nCI/CD for build and test pipelines (we use self-hosted GitLab CI)\n\nBenefits\nWork closely with a team on the cutting edge of AI research\nAn opportunity to fundamentally change the way humanity makes progress through materials science discovery\n100% employer-covered medical, dental, and vision insurance\nUnlimited PTO\n14+ company holidays\n2 weeks of company shutdown at EOY\n401(k)\nMental health support\n\nCompany Overview\nRadical AI develops and applies artificial intelligence and automated laboratory systems to accelerate materials research and discovery. It was founded in 2024, and is headquartered in New York, New York, USA, with a workforce of 11-50 employees. Its website is https://www.radical-ai.com/.\n\nCompany H1B Sponsorship\nRadical AI has a track record of offering H1B sponsorships, with 2 in 2026, 1 in 2025.
