CAREERS Two roles · Colombo · Spring 2026

Help us build
the island,
in code.

OneCeylon is a small travel-tech company in Colombo with two real products, real customers, and — more importantly — real tourists who depend on us getting this right before their train leaves. We are hiring two people. The descriptions below are honest. The work is real, the users are waiting, and the code you write ships to the traveller in the tuk-tuk.

Senior Mobile Engineer

Build OneCeylon's first mobile app. The platform has been web-only while we found our shape — now the travellers are on the road, and they need us in their pocket. You are the first mobile hire, and the first commit is yours.

§ — In plain English

What you can reasonably expect from working here.

Your code will reach real travellers.

A question answered faster, a scam avoided, a train caught. The feedback loop between you and a visitor in Sigiriya is shorter than most jobs ever offer.

Your evenings will stay yours.

We ship quickly because we work deliberately, not because we work late. Sustainable pace is company policy, not a perk.

You will write for the notebook.

Everyone here publishes at least one engineering or research piece a year. It makes us clearer thinkers, and your résumé gets the byline.

Health and kit, covered.

Comprehensive health insurance for you and your family, the hardware you need without an approval chain, and a monthly book allowance nobody audits.

§ — How hiring works

Four steps. Two weeks, at most.

STEP 01 · 20 MIN

You apply.

Email the relevant address with your CV and a short note on why this role. No cover-letter theatre.

STEP 02 · 30 MIN

We call.

A conversation about your work, our work, and whether the two overlap. On the phone, not a platform.

STEP 03 · 2–3 HRS

A real task.

A paid, take-home exercise based on a real problem from our product. We read it carefully and send feedback either way.

STEP 04 · HALF DAY

Meet the team.

You visit Colombo 05, meet the three people you will work with most, and go home with an offer or a thoughtful no.
