Software Engineer, Web Platforms

We're looking for a web platform engineer to lead the development of the LM Studio Hub, lmstudio.ai, and future web surfaces. You will design and build secure, fast, and reliable experiences across Next.js (with RSC), edge/server runtimes (Cloudflare Workers/Pages), data layers, and caching. You are performance and security-minded, with a strong sense of product quality and polish.

You've done this end‑to‑end: designed databases and migrations; built server actions and gateway functions; added typed KV caches; tuned D1/SQL queries; and shipped UIs that feel instant and accessible. You bring expert networking and security knowledge — HTTP, TLS, WebSockets/SSE, proxies, CDNs, caching — and use it to design resilient code that's sufficiently easy to reason about.

- Expert TypeScript and Next.js. RSC, routing, data fetching/caching, edge vs Node.

- Cloudflare Workers/Pages, KV, and D1 experience / understanding.

- Databases: schema design, indexing, query optimization, migrations, reliability.

- Security and networking fundamentals: HTTP, TLS, WebSockets/SSE, CSP, CSRF/XSS/SSRF etc.

- Expert ability to debug performance, reliability, and security issues end-to-end.

- Experience with CI/CD approaches, testing, monitoring, and observability.

- Strong communication: design docs, code reviews, cross-team collaboration.

We aim to build delightful and potent creation tools for AI. We are a small team based in New York. Everyone on the team is IC-minded, intellectually curious, self-motivated, and loves software. We care deeply about our user community and we strive to build canonical software that users and developers love.

Our products include the LM Studio desktop app, our developer SDKs: lmstudio-js and lmstudio-python, our CLI lms, MLX engine mlx-engine for M-chip Macs, venvstacks which enables us to ship Python-based software, the collaboration Hub for individuals and teams, and more currently being built.
