Frontend Systems Developer

Atomic Machines is ushering in a new era of micromanufacturing with its Matter Compiler™ technology platform. This platform enables new classes of micromachines to be designed and built by providing manufacturing processes and a materials library that are inaccessible to semiconductor manufacturing methods. It unlocks MEMS manufacturing not only for device classes that could never be produced by semiconductor methods, but also for entirely new categories.

Furthermore, this digital platform is fully programmable in the way 3D printing is digital—but whereas 3D printing produces parts of a single material using a single process, the Matter Compiler™ technology platform is a multi-process, multi-material system: bits and raw materials go in, and complete, functional micromachines come out.

Our offices are in Emeryville and Santa Clara, California.

In this role you will help maintain and extend a web-based visual graph editor for manufacturing workflows. Users create and connect nodes representing materials/work pieces/tools and manufacturing steps (processes/inspections), validate the resulting workflow against catalogs and strict data contracts, and export a schema‑compliant JSON representation for downstream tooling. This role blends UI engineering with data integrity work. The editor must stay responsive on large graphs, preserve correctness (IDs, validation, export format), and support collaboration workflows through version control integrations.

• 1st 60 days: 20‑40 hours per week
• Ongoing: 10‑20 hours (minimum) per week

• Build and maintain a React + Type Script UI for a graph editor (node/edge creation, selection, multi‑select, drag/drop, property panels).
• Implement schema‑driven validation and export (JSON Schema / AJV), ensuring stable, backwards‑compatible outputs as schemas evolve.
• Improve performance and reliability for large graphs (rendering, minimizing re‑renders, preventing UI jitter, safe persistence).
• Support workflows around identity/, including , transformations on copy/paste/import, and “minting/locking” behaviors that freeze certain fields once finalized.
• Maintain integrations used in real production workflows:
  • Git Lab API (branching, committing files, MR workflows)
  • Methods API (catalog sync, offline fallback, validation that blocks pushes when API is down)
  • Authentication (Okta)
• Ship small‑to‑medium features end‑to‑end: UI, state changes, validation, tests, and docs.
• Triage bugs from real users (manufacturing/process engineers), reproduce quickly, and implement safe fixes.
• Add/maintain unit tests (Jest + TS) around tricky logic (, export validation, API sync behavior).
• Keep the build/lint/test pipeline healthy (Vite, Type Script, ESLint, Jest) and handle dependency upgrades carefully.
• Collaborate asynchronously with a cross‑functional team (process, production, AI) through clear PRs, strong commit hygiene, and pragmatic technical decisions.

• ~3+ years building production web apps with React + Type Script.
• Experience with complex client‑side state and data integrity (persistence, migrations, “single source of truth” patterns).
• Comfort working in a codebase where correctness matters (validation, deterministic export formats, backwards compatibility).
• Experience integrating with REST APIs and handling offline/error modes gracefully.
• Ability to write and maintain tests for non‑trivial logic (not just snapshot/UI smoke tests).

• Manufacturing background (MES, process planning, CAD/CAM adjacent tooling, “recipes/methods/catalog” concepts).
• JSON Schema / AJV experience and comfort with strict data contracts.
• Git Lab API experience, auth systems (Okta/OIDC), or “internal tool” deployment constraints.
