A seed-stage company is building agent-native risk infrastructure: risk management and trust building, delivered by AI agents, for a world increasingly run by them. Their agents sit on top of proprietary data and reassess continuously rather than at fixed checkpoints - so customers spend their time deciding and acting on what matters, not assembling evidence to get there.
Seven-figure revenue within months of launch, on multi-year contracts with leading enterprises in financial services, regulated technology, and healthcare. Founders from Palantir, Oxford, Stanford, and ETH. Backed by leading UK and US institutional investors and angels from Meta, Isomorphic Labs, Palantir, and SpaceX.
The role
You build the backend services at the core of the platform, and you own the foundations on which they run. Most engineers can ship a service - you're the one who also knows how it should be deployed, isolated, observed, and secured in a multi-tenant enterprise environment. That combination is rare, and it's exactly what's needed as the platform becomes load-bearing for regulated customers. Your work decides which customers the company can win at all. The security and compliance teams at banks and hospitals won't sign until they're convinced the platform underneath is as trustworthy as the work it produces. You own that layer.
What you'll do
- Build and own backend services across the platform - APIs, async workflows, and data models - with the same care you bring to the infrastructure under them
- Shape the Azure foundations: Container Apps, Service Bus, Front Door, Entra ID, all under Terraform
- Design multi-tenant isolation patterns across compute, data, and network layers
- Own the deployment pipelines, observability stack, and on-call posture as the platform scales
- Build platform capabilities the rest of the team depends on: long-running agent jobs, large document processing, secure tool execution
- Drive compliance evidence automation and the broader compliance plumbing
- Build internal skill files, scripts, and tools that allow others to develop new features whilst keeping the platform secure and reliable
What you bring
- 6+ years of backend engineering with deep infrastructure experience - you ship services and own how they run
- Significant Azure time (AWS or GCP fine if you'll ramp on Azure fast)
- Strong in a backend language - TypeScript ideally, or adjacent with appetite to switch
- Production IaC (Terraform), CI/CD (GitHub Actions or similar), and container orchestration
- Strong security posture: IAM, network segmentation, secrets, supply chain
- End-to-end compliance ownership (SOC 2, ISO 27001, or similar): designing the controls, not just answering about them
- Operational maturity: you've been on-call for systems that mattered
Nice to have: AKS, Service Bus, or Front Door at scale, multi-tenant SaaS isolation experience, running infrastructure for an audit-sensitive product
