Founding Engineer | $20m Series A | Cloud Security
London | On-site | High Ownership
$20m raised. ARR doubled in the last quarter. Now hiring engineers to build the next stage of the company.
I'm working with a rapidly scaling cloud security start-up taking a different approach to threat detection.
Rather than simply monitoring cloud environments for suspicious activity, they're building decoy cloud infrastructure designed to expose attackers when they interact with it.
They're looking for a Founding Engineer to work directly with the technical founders and take ownership of core product development.
Who they're looking for:
- 6–7+ years building production software
- Strong backend engineering and system design fundamentals
- Experience with cloud infrastructure (AWS, Azure or GCP)
- Comfortable owning technically complex systems end-to-end
- Product-minded, pragmatic and happy operating without established processes
Why this one?
You'll join a company with significant funding, strong commercial momentum and a genuinely differentiated technical product.
You'll work directly with experienced founders, ship meaningful product and have real influence over the engineering foundations.
📍 Central London | 5 days on-site, with sensible flexibility.
