Senior Product Engineer – Generative AI

Build AI products that move beyond prototypes

You’ll join a growing AI technology business at a point where its products are gaining serious commercial traction across Southeast Asia. This is a senior, hands-on role where you’ll have the autonomy to turn ideas into production-ready AI products used by major international brands.

What’s in it for you

  • You’ll own products across the full journey, from early technical decisions through launch, adoption and continuous improvement.

  • You’ll work on production Generative AI, including LLM applications, retrieval-based systems and intelligent automated workflows.

  • You’ll have significant influence over architecture, engineering standards and how the team approaches AI product development.

  • You’ll work closely with the Founder, giving you direct exposure to commercial strategy and product direction without unnecessary layers of management.

  • You’ll receive meaningful equity, alongside comprehensive health insurance and a flexible fitness/wellness allowance.

  • You’ll get genuine flexibility, with three days working remotely and two days collaborating from the Bangkok office each week.

What you’ll be doing

You’ll combine senior full-stack engineering with product thinking, taking ambiguous commercial opportunities and turning them into scalable software. You’ll make architectural decisions, build across the TypeScript stack and integrate modern LLM technologies into customer-facing products. You’ll also use customer feedback and performance data to influence priorities, while helping establish the technical standards needed for the engineering function to scale.

Your background

  • You’ll bring 7+ years of full-stack software engineering experience, with strong production-level TypeScript skills and hands-on experience with Next.js and NestJS.

  • You’ll have previously taken a software product from an early concept through launch and subsequent growth.

  • You’ll have shipped real-world Generative AI functionality using LangChain, Vercel AI SDK or comparable tooling.

  • You’ll be comfortable working with technologies such as PostgreSQL, vector databases, Azure/AWS and modern LLM APIs.

  • You’ll communicate confidently in English and be comfortable working with customers and stakeholders across international markets.

  • You’ll suit an environment where senior engineers are expected to make decisions, challenge assumptions constructively and operate effectively without rigid processes.

The environment

You’ll join an early-stage AI business building commercial technology for the rapidly expanding Southeast Asian market. You’ll be working in a high-ownership environment with ambitious product plans, established enterprise demand and the opportunity to shape both the technology and engineering culture as the company grows.
