Back-End Developer — Core API & Application (TypeScript / Node.js)

About the Role
We are a fast-growing SaaS company building an AI-powered business platform that brings CRM, content generation, lead generation, automation, and messaging into one connected system. We are hiring a back-end developer who is strong on REST APIs and business logic.

Our stack is TypeScript, Node.js, PostgreSQL, and Supabase, with integrations across AI services, payment processing, and other third-party platforms. When the team d ---------- on a new automation, a new capability, or a new way of handling user data, you are the developer who makes it real on the back end. You will design REST APIs, implement business logic, and ship features end to end.

You will also handle integration work as new third-party services come online — payment flows, AI model wiring, webhook handlers. You will work alongside our lead engineer and the rest of the back-end team. We are a small team that respects deep work, communicates honestly, and ships often. You will have real ownership of the features you build and the support of a team that has your back.

Core Skills (Required)
TypeScript and Node.js — this is the stack
REST API design and implementation
PostgreSQL — schema design, indexing, query fundamentals
Authentication patterns (OAuth, JWT)
Comfortable with third-party APIs and webhooks
Solid Git and code review habits
Clear written English for documentation and daily team communication

Extra consideration for experience with AI/LLM API integration (OpenAI, Anthropic, or similar), Supabase, payment integration (Stripe or similar), Next.js API routes, AI-assisted development (Claude Code, Cursor, Copilot), and SaaS or multi-tenant architecture.

Schedule and Availability
Full-time, 40 hours per week. Our core team window is 12:00 PM – 8:00 PM PHT, Monday through Friday.

Pay
Open to discussion based on experience.

How to Apply
Reply with a short message that includes:

3. Your top 3–5 strongest technologies or platforms — be specific (Node.js, TypeScript, PostgreSQL, REST APIs, Stripe, OpenAI API, etc.).
4. Link to your GitHub, portfolio, or any production work you can show — we want to see what you've built.
5. Are you currently working with other companies? How many hours per week are you available, and what is your timezone?
6. Answer this: Describe a feature you built end to end on the back end. What problem it solved, how you designed the API, and one tradeoff you had to make.
