Frontend Systems Developer

~3+ years building production web apps with React + TypeScript.

Graph/diagram editor experience (ReactFlow, D3, jointjs, etc.).

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).

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/workpieces/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), as well as support collaboration workflows through version control integrations.

Build and maintain a React + TypeScript 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.
