Job description

As an engineer at Bask you’ll work directly with the CEO and CTO on the surfaces people meet us through first — where 3D does the heavy lifting.

We’re expanding our engineering team and looking for people with a deep entrepreneurial streak.

Our serverless platform runs on Next.js, tRPC, Drizzle, and SST across a multi-tenant monorepo. This role starts on the front end and grows into it — everyone here ends up full-stack. We hire people who get bored inside one layer.

Engineering at Bask Health is AI-first and builder-led. Work starts in an LLM to clarify intent and constraints, moves into tools like Claude and Cursor to explore and build, is tested with real users, and then comes back for systems and polish. AI is a default part of how we work, not a side experiment — because moving fast in healthcare requires every advantage.

It’s also why we care about real 3D depth. An LLM will scaffold a form. It won’t tell you why you dropped to 22fps on a mid-tier phone.

We are looking for engineers who take end-to-end ownership, treat AI as a real collaborator, and care deeply about building software that meaningfully improves how healthcare is delivered.

What You’ll Do

• Own our WebGL work end to end. Scene architecture, motion, art direction in code, and the frame budget it lives inside.
• Design and ship, not just implement. You’ll have real latitude over how this looks and feels.
• Work AI-first with Cursor and Claude Code. Draft intent, explore, scaffold, refactor with AI in the loop — then apply your own judgment.
• Prototype fast and validate. Build quickly, put it in front of real users, refine before committing.
• Hold the bar on performance and accessibility. Fast on a mid-tier phone, reduced-motion respected, graceful when WebGL isn’t available.
• Build patterns, not one-offs. Make the next surface faster to ship than the last.
• Share what works. Document the prompts and workflows that move the team.

We are a highly collaborative team.

Who We’re Looking For

Someone entrepreneurial who’s taken products from 0 to 1, willing to roll up their sleeves, and drawn to a mission that disrupts how healthcare gets delivered.

• Shipped WebGL we can open — Three.js or React Three Fiber, live, running on a phone.
• Highly skilled with React, TypeScript, Next.js, and JavaScript.
• Real taste in motion, timing, and restraint — and the ability to defend it.
• Enough backend to be dangerous (Node, SQL) and an appetite for SST and Drizzle. Not required on day one.
• Comfortable owning entire projects and large areas of a codebase independently.
• Experience building paid products and services.
• A strong communicator — clear on technical problems, constraints, and timelines.
• Comfortable in a fast-paced, unstructured, startup environment.
