We're growing fast and looking for a Senior Backend Engineer to join our AppSec Solution group, home of company core platform, and play a key role in shaping the architecture and infrastructure the whole product runs on.
This is a high-impact, cross-functional role where you'll work closely with our Software Architect, team leads across R&D, DevOps and Product, helping us build the foundations for what comes next, including running AI agents inside the product at scale.

- Deep experience with databases at scale: data modelling, performance, and evolving a data layer in production
- Proven hands-on experience in platform engineering and infrastructure, including shared foundations adopted across teams
- Hands-on experience with Kubernetes and a strong understanding of DevOps practices
- Track record of leading cross-team technical projects and influencing without formal authority
- Clear written communication: design docs and technical reviews
