Job Description

Senior Full-Stack Developer, AI-Assisted

Productiv Teams

• Build the final pipeline agent (the certification builder), including schema design, LLM prompt and output design, and a review and approval workflow • Own multi-tenant readiness: role-based access control, a membership model, email invitations, and self-serve workspace provisioning • Bring database maturity to the project: adopt a formal migration workflow and separate staging from production data • Lead production hardening: rate limiting and usage budgets for AI endpoints, a cloud IAM and security review, secrets and environment hygiene, and error observability • Set up engineering process: a CI pipeline and broader test coverage • Improve the structure of a fast-grown codebase while continuing to ship features • Make build-vs-buy calls, write specs, and mentor a junior engineer

Job Requirements

  • Deep TypeScript and modern React/Next.js experience (App Router, Server Components, Server Actions)
  • Production SaaS backend experience: multi-tenant data models, role and permission systems, and auth flows (OAuth, JWT sessions)
  • Relational database maturity: Postgres with an ORM (Prisma preferred), a sound migration strategy, and safe schema changes on a live database
  • Distributed-systems fundamentals in a serverless world: queues, webhooks, idempotency, retries and backoff, timeouts
  • LLM product engineering experience: prompt design, structured and validated outputs, awareness of token costs, and graceful degradation when a model or data source fails
  • Security instincts: able to run a cloud IAM review (GCP or equivalent), reason about tenant isolation across data, storage, and real-time layers, and know where rate limiting and secrets hygiene belong
  • Strong judgment and comfort being the most senior engineer on the project
  • Strong async communication: clear technical questions, documented decisions, and self-surfaced blockers

Benefits

  • All our positions are Remote and are available as Full Time Employment or B2B Contracts
