Build the systems our clients run their business on.

You build what our clients buy: AI agents that take repetitive work off a team, integrations that join the tools a business already uses, and web applications and websites. Our projects are focused and fixed-price, and you work closely with the client, so you see your work in use.

You work across the stack and through the whole project. You join Discovery, our scoping step, to estimate the work, then build it, test it, deploy it and hand it over with documentation. After launch, you help keep it running under Care, our monthly support plan.

What you’ll do

  • Build web applications end to end with TypeScript, React or Next.js, and Node.js or Python
  • Design data models and APIs on PostgreSQL
  • Connect client systems such as LINE, payment providers, accounting software and ERP through APIs, webhooks and browser automation
  • Use LLM APIs to build agents and assistants that answer from documents, with evaluation and human review built in
  • Deploy to the cloud with Docker and CI, and set up monitoring and backups
  • Estimate the work in Discovery and help write the scope
  • Write tests and documentation, and hand projects over to client teams
  • Fix issues and improve live systems under Care

What we’re looking for

  • At least 3 years building and shipping web applications used in production
  • Strong TypeScript and React skills, and backend experience in Node.js or Python
  • SQL and data modeling skills, ideally in PostgreSQL
  • Experience with third-party APIs, webhooks and authentication
  • Git, code review and automated tests as part of your daily work
  • Able to explain technical choices to a client in plain language
  • Thai, and English good enough to read and write documentation

Nice to have

  • Experience building with LLM APIs (Claude, OpenAI or Gemini), LangGraph or MCP
  • Experience automating workflows with n8n, Playwright or similar tools
  • Experience deploying to Google Cloud, AWS or Cloudflare, and using Docker
  • Experience integrating with LINE, payment providers (Omise or Stripe) or accounting software (PEAK or FlowAccount)
  • An eye for design and interface detail

What you’ll build

You’ll work across all eight of our services. Every build follows Discovery and a written scope, so you start with a clear plan.
