Full Stack Software Engineer – Nopex Platform

About the role

Your responsibilities

• Build end-to-end features: Next.js 16 / React (shadcn/ui, Nopex Design System) ↔ Fastify / NestJS APIs ↔ PostgreSQL (Drizzle) ↔ Redis/BullMQ
• Design product surfaces that both humans and AI agents consume — REST APIs with Zod, MCP tools, SSE/WebSocket streams
• Extend the Swarm: write new persona plugins, tools, workspace drivers, or transport adapters
• Touch the platform plumbing: pipelines in Stack, deployment drivers in Hive, webhook flows in Billing Gateway
• Own production: Sentry instrumentation, Playwright/Vitest coverage, k8s manifests, on-call when things wobble
• Pair with our own AI agents — reviewing PRs from Swarm as often as you write them yourself

What you bring

• 4+ years building production TypeScript across frontend and backend
• Solid Next.js / React and at least one Node backend framework (Fastify or Nest)
• Comfort with PostgreSQL, an ORM (Drizzle/Prisma), and Redis-based queues
• Working knowledge of Docker and Kubernetes — no SRE bar, but `kubectl describe` shouldn't scare you
• Opinions about API design, type safety, and where validation belongs
• A pragmatic stance on AI tooling — neither hype-driven nor allergic

Nice to have

• LLM/agent experience (Anthropic, OpenAI, MCP, prompt caching, tool-use protocols)
• Monorepo tooling (pnpm workspaces, Turbo)
• Drizzle migrations, Zod-first API contracts, OpenAPI 3.1
• Observability deep-dives (Sentry, OTel, trace UIs)

What we offer

• A platform where your code is amplified by an army of agents
• Small senior team — few meetings, lots of write-access, decisions in days
• Modern stack with no legacy weight: TS strict, Drizzle, Fastify, Next 16, K8s-native
• Karlsruhe office with home-office on selected days
• 30 days vacation, top equipment
• Conferences & events — we want you connected
