Meet the team

The engineers behind Iontek.

Senior AI and data engineers across the UK, Pakistan, and beyond. Every person on this page has shipped AI to production. None of them are here to manage a project — they are here to build it.

Humayon Khan

Verified Engineer

I started Iontek after years of building data and AI systems in production and watching talented businesses lose time, money, and momentum to problems the right technology could quietly solve. Most had tried the popular AI tools and walked away frustrated — because generic software was never built for how they actually work.

My approach is simple: understand the business before touching the code, plan before building, and stay accountable long after launch. I work directly with every client through every phase. The senior engineer in the first meeting is the same person deploying on launch day.

How we work

Built on principles, not process.

The same values that shape how we hire are the ones that shape how we build for you.

Senior engineers only.

We do not staff projects with juniors or pass work down a chain. The engineer in the first meeting is the same one who builds, deploys, and answers for the result.

Honest over polished.

We will tell you when an idea is not worth building yet. We will tell you if the data is not ready. Our reputation depends on your results, not how well we pitch.

Remote-first, worldwide.

UK, Pakistan, and distributed globally. We work async by default and synchronously when it matters. Timezone spread means someone is always close to the work.

Partners, not vendors.

We stay invested after launch. Your AI improves over time, and so does our relationship. We are not looking for one-off projects — we are looking for businesses to grow with.

10+ Engineers on the team
5 Countries represented
50+ AI builds shipped
3+ Years in production AI

We’re always looking for exceptional engineers.

Senior AI or data engineer who ships production-grade code and cares about the problems it solves? We would like to talk. No recruiters, no lengthy process — just a direct conversation.
