Backend Engineer (Contract)— AI Email Assistant for Gmail

Type: 4 Week Contract
Opportunity: Potential for Full-Time Employment with Equity Participation
Location: Remote
Start Date: May 26th, 2025

About the Product

We are an early-stage, AI-first startup building a focused, industry-specific AI Email Assistant for Gmail. Our front-end is already complete, and our fully functional end-to-end prototype is already built in n8n. We are now ready to evolve it into a production-grade SaaS platform.

While our logic is fully mapped in n8n, this workflow is for reference only. You will be responsible for rebuilding the agent execution pipeline in production-grade TypeScript, including task orchestration, API integrations, and queue-based processing. Experience building AI agent pipelines (e.g., using LangChain or custom orchestrators) is highly valued.
You will not be responsible for front-end development, prompt engineering, or fine-tuning the AI model. These have already been completed and are managed in-house. Your sole focus will be on building the production backend to scale the service for real users.

As part of this next phase, you will lead backend development to support:

1. User Sign-up and Authentication via Google.
2. Secure Gmail Access where users grant Gmail read and draft permissions through Google OAuth, with persistent background access via refresh tokens (access_type=offline).
3. AI-Powered Inbox Automation, leveraging our deployed fine-tuned open-source LLM to label and draft replies in real time.

We have chosen a lightweight, scalable architecture to validate product-market fit efficiently:

• Auth & Database: Supabase Auth + Postgres (Row-Level Security)
• Inbox Access: Google OAuth (offline Gmail scopes)
• Queue & Workers: Node.js / BullMQ via Supabase Edge Functions (or Railway)
• AI: Fine-tuned Qwen 2.5-32B on OpenPipe (fully managed in-house)
• Frontend: Next.js (already developed in-house)

Your Responsibilities

OAuth 2.0 & Gmail API Integration

• Implement secure Google OAuth 2.0 authentication with refresh token management.
• Set up Gmail "watch" webhooks and history ID-based synchronization.
• Manage label application and draft creation through Gmail API v3.

Workflow Orchestration

• Refactor existing n8n logic into production-grade TypeScript queue workers using BullMQ or Redis.
• Ensure step-by-step agent execution, tool/API calling orchestration, error recovery, and observability.

Supabase Integration

• Leverage Row-Level Security (RLS) for secure, multi-tenant data handling.
• Develop Edge Functions and webhooks for Gmail notifications and future Stripe billing events.

AI Integration

• Integrate with our OpenPipe-hosted LLM, managing API interactions, batching, and rate limits. You will not be responsible for prompt engineering or model fine-tuning, but your feedback and collaboration are highly valued.

DevOps & CI/CD

• Dockerize services and set up CI/CD pipelines with GitHub Actions.
• Implement basic observability through monitoring tools such as Sentry and log management systems.

AI-First Development Requirements

• Required: You must be proficient in using Generative AI development tools such as Cursor, Windsurf, or equivalent AI-powered IDEs to accelerate delivery and maximize productivity.
• We are an AI-first company and expect daily, thoughtful application of GenAI tooling in your development workflow.

Required Experience

• 3+ years of hands-on experience building production-grade Node.js / TypeScript backends.
• Proven experience with Supabase Auth, Firebase Auth, or similar authentication services.
• Experience with Gmail API or Google Workspace Add-on development.
• Deep understanding of OAuth 2.0 flows, including PKCE and refresh token management.
• Experience with job-queue architectures (BullMQ, SQS, Cloud Tasks).
• Familiarity with Postgres schema design and Row-Level Security (RLS).
• Experience deploying Redis and managing worker queues.
• Strong DevOps skills, including Docker and CI/CD tooling.
• Experience with Stripe webhooks and subscription billing workflows.
• Exposure to OpenAI-compatible LLM APIs (OpenPipe).
• Familiarity with WorkOS or Auth0 for future enterprise SSO integrations.
• Experience building agent execution pipelines (e.g., LangChain or custom orchestrators) is highly valued.

What We Offer

• End-to-End Ownership — You will lead the architecture and implementation of our production backend from day one.
• Impact-Driven Development — You will ship value to real users quickly and receive direct feedback from the market.
• Lean, Scalable Stack — Our Supabase + Vercel + OpenPipe architecture allows you to move fast without heavy DevOps overhead.
• Future Growth Opportunity — Strong potential for transition to a full-time role with meaningful equity as we grow.

We move fast and are looking for focused, AI-first engineers who thrive on shipping meaningful products—qualified candidates will progress quickly through a short technical discussion and a paid assessment.
