Senior Full Stack Software Engineer

Delivery Module Lead

Senior Full-Stack Engineer ×3

Headcount: 3 identical roles · Level: Senior

What these people do

Three interchangeable senior engineers who collectively own all 19 backend modules, all 6 frontend portals, all adapter implementations, and all test coverage. Work is divided by domain area, not by technology layer — each engineer owns a domain end-to-end (backend module + matching portal + tests), eliminating handoffs.

Suggested domain split (adjust per strengths):

Responsibilities

Backend (NestJS · Prisma · PostgreSQL)

• Implement and own assigned NestJS modules: service, controller, DTOs, Prisma queries, pgboss job handlers
• Write main.worker.ts job handlers for async tasks and outbox relay within owned modules
• Implement and extend adapter interfaces (LlmAdapter, OcrAdapter, StorageAdapter, EmailAdapter, SmsAdapter) for assigned modules
• Add @ApiOperation, @ApiResponse, @ApiProperty decorators on all controllers — keeping the OpenAPI spec accurate and complete
• Implement Cerbos RBAC + ABAC policy calls within modules (authority limits, separation of duties, jurisdiction checks)
• Maintain prisma/schema.prisma models for owned modules in coordination with the Tech Lead
• Write Vitest unit tests and Supertest integration tests achieving agreed coverage targets

Frontend (React 19 · TanStack Query · Zod · Tailwind)

• Build and maintain all pages within assigned portal layout routes
• Implement TanStack Query hooks for all API endpoints in owned portals; manage cache invalidation, optimistic updates, and error boundaries
• Implement React Hook Form + Zod validation forms using OpenAPI-derived schemas
• Build shared src/components/ design system elements (shadcn/ui + Tailwind 4) when adding new component patterns
• Run openapi-typescript / orval after backend spec changes to regenerate generated/types.ts and generated/api-client.ts
• Implement Zustand stores for UI state within owned portals (sidebar state, filters, modals)
• Write Vitest component tests and Playwright E2E tests for owned portal flows
• Maintain WCAG 2.1 AA compliance within owned portals; integrate axe-core checks

Cross-Cutting

• Contribute to code review across all modules (not just owned domain)
• Escalate schema design decisions and cross-module interface changes to the Tech Lead before implementing

Must-Have Skills

• TypeScript — expert
• NestJS (modules, guards, interceptors, decorators, pipes) — expert
• React 19 (hooks, Router 7, lazy loading, error boundaries) — expert
• Prisma + PostgreSQL — solid
• TanStack Query, React Hook Form, Zod — solid
• Tailwind 4 + shadcn/ui — solid
• Vite / build tooling — working knowledge
• REST API design and OpenAPI spec authoring — solid
• Ability to work without a frontend/backend handoff boundary — essential

Nice-to-Have Skills

• Insurance domain knowledge (claims, billing, underwriting)
• Keycloak JS adapter / JWT auth patterns
• pgboss or similar durable job queues
• Cerbos policy authoring
