## About the Role

* 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

Nice to Have

 * Real-time collaboration experience (Yjs, Liveblocks, or ProseMirror/Tiptap internals)
 * Google Cloud specifics: Cloud Run, workload identity federation, GCS signed URLs
 * Experience taking an early-stage product to its first paying customers

## Description

We are looking for a Senior Full-Stack Developer to help build and harden a TypeScript, front-to-back product built on Next.js 15, React 19, and an AI pipeline powered by Anthropic Claude., * 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
