About Us | Longnium

Who we are

A specialist, not a generalist agency

Longnium is a specialist IT outsourcing partner focused on one thing: building finance, blockchain and AI products that work at real scale. We are not a generalist agency that happens to take on fintech projects. Every engineer, designer and strategist on our team works exclusively in this space. That focus means we understand the difference between a demo and a system ready for real trading volume, and we build accordingly, from first prototype through to daily operations.

Our culture

Small, senior, accountable squads

We’re a team of builders who care about getting the hard parts right, and it shows in how we work.

Small squads, not layers

We work in small, senior, accountable teams rather than large, layered ones, so decisions move fast and nothing gets lost in translation between you and the people actually writing the code.

Directness over politeness

We value directness over politeness when it comes to technical trade-offs. We’d rather flag a risk early than let it surface after launch.

Ownership after launch

If we build it, we care how it performs after we ship it. Ownership doesn’t end at the deployment step.

Our location

Regional roots, global culture

Remote-first, by design

Talent, not zip codes

Longnium operates remote-first by design, not by accident. Our squads are built around talent, which lets us pull senior engineers and specialists from across the region into every engagement. Wherever you are based, you are working with a team used to operating globally, not a satellite office translating for you.

Vietnam

Our largest engineering hub, covering backend, smart contract and AI/ML engineering.

Malaysia

Product, design and QA specialists, embedded closely with client-facing delivery leads.

Singapore

Client strategy and regional business development, close to the region’s major financial centers.

We work in English by default, collaborate across time zones as routine, and build for clients well beyond Southeast Asia.

Careers

Work on hard, high-stakes problems

We are always looking for people who want to work on hard, high-stakes problems in finance, blockchain and AI, not incremental feature work. If you are the kind of engineer, designer or strategist who wants ownership over what you build and cares about it working in production, not just in a demo, we would like to hear from you.
