Senior Software Engineer
Backend / Data Engineer | London Hybrid | £130k + EMI Equity 🚀
Most senior engineers we speak to are good at their job, enjoy the work, but feel like they're a few layers removed from anything that actually matters. Tickets come in, tickets go out. The architecture decisions get made above them. The equity is underwater or non-existent.
This is the opposite of that.
A pre-seed AI company founded by executives from some of Europe's best known fintech unicorns, backed by top-tier global VCs is hiring the engineer who owns their entire data and infrastructure platform. Not a slice of it. All of it.
The product is genuinely ambitious. An AI-native operating system that learns how humans make decisions and uses that to coordinate AI agents across every tool a business runs on. The data layer is what makes it work and right now there's no one who owns it end to end. That's the gap you're filling.
You sit between the data and the AI engineers. You design the architecture, you own the AWS platform, you decide how data moves, transforms, gets stored and retrieved across relational, vector, document, object and blob stores. You set the foundations the whole product is built on. As you perform, the scope grows.
The setup:
- 9 engineers, no PMs, no product owners, flat structure
- Daily standups, direct access to the co-founders
- High autonomy, high accountability
- Nobody to hide behind and nobody slowing you down
The stack:
- AWS (primary), Python services REST/RPC and queue-based
- Vector DBs, relational, document, object and blob storage
- Terraform IaC, system design for AI workloads
- Sync vs async, throughput, latency, consistency you own those trade-offs
The package:
- £130k base
- EMI equity options at pre-Series A entry point, this is the stage where equity actually means something
- London hybrid, no enforced days
The process is four stages and moves fast: intro call with the co-founder, Python coding test, system design interview and culture fit.
If you're technically excellent, a bit tired of the layers, and want to go and build something that matters, drop me a message and apply today.
