Senior Backend Engineer (Node.js / TypeScript)

About the role

You'll be the technical owner on customer engagements, usually 4-12 weeks of project work or longer dedicated-pod retainers. You'll write production code, review every PR (yours and AI's), and stand behind the architecture you ship. We're a senior-only studio: no juniors guarded by one senior, no agency-of-the-week mid-levels.

What you'll do

• Design and ship backend services in TypeScript / Node.js: APIs, ledgers, integrations, queues, webhooks.
• Own architecture decisions: data model, deployment shape, observability, on-call story.
• Pair with QA and Security engineers from day one of the engagement, not at the end.
• Use AI assistants for scaffolding, code review, and test generation; reject what's wrong; keep what's right.
• Demo working software every Friday. Document as part of the Definition of Done.
• Hand over to client teams with runbooks, decision logs, and onboarding sessions.

What you bring

• 5+ years building production backends in TypeScript / Node.js (or strong Go / Python adjacent + clear path to TS).
• Deep PostgreSQL knowledge: schema design, indexing, query plans, migrations under traffic.
• Comfort with AWS (or GCP / Azure) at the level needed to ship: ECS / Lambda / RDS / S3 / IAM.
• Track record of owning a production system end-to-end, not just shipping features into one.
• Written communication good enough that documentation isn't a chore.
• Comfort working async across at least one time-zone boundary (US, UK, EU, or ME).

Nice to have

• Stripe / payment-rails integration experience (Issuing, Connect, billing).
• Multi-tenant SaaS architecture experience.
• OSS contributions or technical writing.
