KustomAI

Build software that runs real businesses.

Not a landing page. Not a pitch deck. Real cafés, real factories, real payroll. We are hiring in Phnom Penh.

Why here

Real users, day one
What you build today is on a till tonight. Your feedback loop is a phone call, not a quarterly review.
Own the whole thing
Small team. You touch the database, the UI, the deploy pipeline, and the customer. No layers to hide behind.
Boring, solid stack
Elixir, Phoenix LiveView, Postgres, Fly.io. Chosen because they last, not because they are trending.
Fair pay
Above-market for Cambodia. Full NSSF. Paid public holidays. Real leave. No surprises.
Grow with the company
We are building for the region. If you want to lead a team, open a country, or become the person who trains the next hire — the runway is here.
Learn every day
Book budget. Conference budget. English lessons if you want them. Time to build the thing you have been thinking about.

Open roles

Phnom Penh, on-site or hybrid. Full time. Do not see your role? Write to us anyway — good people are always welcome.

Full-stack engineer
Elixir / Phoenix LiveView / Postgres. You ship end-to-end features to production every week.
Frontend engineer
Tailwind, LiveView, and a bit of JavaScript where it earns its keep. Care about how a receipt looks on a 58mm printer.
Product accountant
CPA or the Cambodian equivalent. Bridge the gap between what accountants need and what engineers build.
Customer support
Answer the phone in Khmer and English. Solve the problem, then write the docs so the next person does not have to call.
Onboarding specialist
Visit new customers, import their data, train their staff, and hand them a running system.
Sales & partnerships
Talk to shops, restaurants, and accounting firms. Understand their business. Sell only what fits.

How we hire

  • You write to us with a note about you and a link to something you have made
  • A 30-minute call — questions both ways
  • A small paid take-home, close to real work (not a whiteboard puzzle)
  • Meet the team over coffee at the office
  • Offer within a week of the last step
  • No trick questions. No unpaid trials. No ghost.
