Founding Backend Engineer for a Secure Azure Platform

TechTree; Greater London; On-site; GBP 100,000 - 180,000; Full time

Job summary

TechTree in London is building the backend services at the core of a risk infrastructure platform. You will own how services run, are deployed, isolated, observed and secured in a multi-tenant enterprise environment, helping regulated customers move faster.

You’ll shape Azure foundations, Terraform and CI/CD pipelines, design multi-tenant isolation, own deployment pipelines and compliance automation, and build tools that enable others to deliver new features securely.

Qualifications

• 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

Responsibilities

• 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
