Principal Full Stack Developer with React (Remote, Global)

What this role really is

Not another senior developer role. We're hiring a Principal Full-Stack Engineer — someone who writes excellent code and owns outcomes: leads projects end-to-end, sets technical direction, and helps other engineers get better.

Your PRs, your design docs, and the way you run a project become the standard others follow.

What you'll do

Lead and own

• Lead complex projects from problem definition through architecture, delivery, and post-release monitoring — we trust you to make the calls
• Set technical standards: API contracts, data models, multi-tenant boundaries, performance targets, migration plans
• Shape how we plan, review, test, release, and respond to incidents — improve the process, don't just follow it
• Grow engineers through code review, pairing, design feedback, 1:1, and clear expectations. Help us hire

Build and ship

• Full-stack features across React frontends, NestJS/GraphQL backend, PostgreSQL/ClickHouse data layers
• Fast UIs that stay responsive under real-time data load; dashboards that turn complex behavioral data into clear signals
• Secure integrations — BI engine, ML prediction engine, LLMs, billing, SSO, third-party APIs — with strict auth and tenant isolation
• Investigate production issues and lead incident response across NextGen and legacy systems

The technical challenges

Real problems on a security-sensitive platform:

• Multi-tenant SaaS and on-prem — one codebase, cloud and air-gapped enterprise installations
• Real-time, high-volume behavioral data — event streams and time-series analytics in interactive dashboards that stay fast under load
• Secure AI/ML integrations — LLM- and ML-powered features on sensitive user-behavior data, where tenant isolation and data handling can't leak
• Modernizing at scale — evolving NextGen while keeping legacy healthy and safely bridging the two

Our stack

Frontend: React 18 + TypeScript, TanStack Router, Apollo/GraphQL, Tailwind, AG Grid Enterprise, d3, Plotly, Vite, Vitest, Cypress, Playwright

Backend: NestJS 10 on Node, GraphQL (Apollo), PostgreSQL + Knex, Redis + BullMQ, WebSockets, JWT/Passport/SAML SSO, OpenTelemetry, Sentry, New Relic, Nx monorepo, pnpm

Platform: Docker, Ansible, TeamCity CI/CD, on-prem packaging pipelines

You don't need every item. You do need the depth to pick up unfamiliar parts fast and own them.

Who you are

• 10+ years full-stack, including 4+ years with React
• Strong backend: NestJS/Express, GraphQL, PostgreSQL, Docker, Node
• System design judgment — CQRS, event sourcing, distributed systems, multi-tenancy — and the taste to know when not to over-engineer
• Have led both projects and people: owned delivery, run reviews, set standards, grown engineers
• Take real ownership of quality, security, and reliability — not just your tickets
• Clear written and spoken English
• Work well fully remote with little supervision

Bonus

• Real-time visualizations or analytics dashboards (d3, AG Grid, Plotly)
• Behavioral data, event streams, or time-series analysis
• ML- or LLM-powered features in production
• Shipped on-prem/self-hosted to enterprise, not just SaaS
• DevOps/CI-CD depth (Docker, Ansible, release pipelines)
• Tech lead or engineering management experience
