Senior Frontend Engineer – Visual Workflow Canvas (react Flow)

Senior Frontend Engineer

Insight Global is seeking a Senior Frontend Engineer to support a large health insurance client. Senior individual contributor and technical lead for a custom-built visual authoring environment that allows the AA delivery community to design, validate, and version Medicare claims processing workflows without writing Python. The canvas is an editor, not a runtime: it produces versioned JSON/YAML workflow configs stored in Git and executed by Temporal workers on GKE. Owns the architecture of the canvas built on React, TypeScript, Vite, and React Flow, including the node/edge model, the schema-driven property-panel pipeline, validation rules, and the integration with the FastAPI canvas backend. This role supports a strategic platform initiative within Medicare Claims Engineering to migrate the existing Automation Anywhere RPA portfolio onto a modern, code-and-config-driven workflow platform built on Temporal.io, Python/Playwright, and Google Kubernetes Engine (GKE). Workflows are visually authored on a custom React Flow canvas that emits versioned configs executed by Temporal workers. The platform operates under HIPAA governance.

Key Responsibilities:

• Own the end-to-end architecture of the React Flow authoring canvas, including node and edge model, typed I/O contracts, sub-flow encapsulation, undo/redo, and large-graph performance.
• Define the three-layer node library architecture (primitives, composites, workflows) and the patterns for property panels generated from schemas.
• Lead architectural decisions for state management, data fetching, schema validation, and module boundaries so the codebase scales as the node library grows.
• Champion the Pydantic-to-Zod codegen pipeline as the single source of truth for node schemas, ensuring runtime validation parity between canvas and execution layers.
• Drive performance and quality on large workflows, including viewport virtualization, selective re-rendering, bundle optimization, and visual regression testing.
• Define and enforce engineering standards: TypeScript strictness, component architecture, testing patterns, accessibility (WCAG 2.1 AA), and design system usage.
• Partner with the Temporal platform team on the workflow config schema (the contract between canvas output and Temporal input) and versioning strategy.
• Partner with Security on PingFederate OAuth2 integration, IAP-fronted ingress, and frontend hardening (CSRF, XSS).
• Mentor senior and mid-level frontend engineers; lead design and code reviews; influence engineering direction across backend, platform, and migration teams.
