Software Engineer

London startups raised £3.14 billion in the first two months of 2026 alone.

The money is concentrating into AI - 34% of all London deal activity, higher average round sizes than any point in 2025, and every one of those funded companies needs to hire fast.

Processes are selective. Founders want engineers who've done it before - startup experience, AI exposure, the ability to own problems end-to-end. The supply of that profile hasn't kept up with the demand for it.

If you're an experienced engineer — mid, senior, staff, principal — and you're thinking about your next move, the timing is genuinely good.

I'm Reuben, founder of Techmunity. I've spent 13 years placing over 500 engineers into high-growth London startups - Starling Bank, Mettle, Tide among them.

I run a tight book of mandates I know inside out - which means if you talk to me, I can tell you exactly what each of these companies is actually like, what the founders are like, and whether you'd be a genuine fit.

Right now I have 11 active searches across 8 companies. Here's what's live:
