  • Assist in the design and documenting of solutions meeting functional and non‑functional requirements.
  • Lead by example getting directly involved in the day‑to‑day delivery of work with hands‑on development, following best practices for maintainability, testability and performance.
  • Participate in sprint planning meetings, daily stand‑ups and sprint retrospectives, striving to continuously improve the team velocity, its processes and engineering practices.
  • Coach and mentor colleagues where appropriate, fostering a collaborative and quality‑focused engineering culture.
Qualifications
What you’ll bring
  • Platform and control plane engineering + Practical experience designing and developing management and control‑plane capabilities for line of business or SaaS applications, including stack/environment management, API design for platform services, and developer/operator UX.
  • Experience working with or designing Azure stamp‑based or scale‑unit architectures, including multi‑region or multi‑tenant deployments, isolation and blast‑radius reduction, and automated stamp lifecycle management.
  • SaaS product lifecycle + Demonstrated experience across the full SaaS development lifecycle: requirements analysis, estimation, architecture/design, implementation, unit and system testing, deployment, operations, monitoring and incident management.
  • Software engineering fundamentals + Strong grounding in object‑oriented design, design patterns, SOLID principles, clean code practices, code review, documentation and Agile delivery.
  • Core technical stack + Hands‑on experience with C# and .NET (Core/6+) for backend and service development.
    + Strong practical experience with Azure cloud and SaaS services (e.g., Container Apps, AKS, Azure Storage, Azure SQL/Cosmos DB, Key Vault, Azure Monitor, Log Analytics).
  • Containers, Container Apps, Kubernetes and microservices + Experience designing, building and operating containerised microservices, including Docker image design, optimisation, Container Apps, Kubernetes (preferably AKS) deployment and scaling strategies, and Kubernetes configuration, secrets and traffic management.
  • Infrastructure as Code and platform automation + Experience with IaC using OpenTofu or Terraform on Azure, producing modular, reusable, and maintainable infrastructure definitions.
    + Experience automating environment and stamp provisioning, implementing blue/green or canary deployments, and detecting/remediating infrastructure drift.
  • CI/CD and DevOps + Hands‑on experience building CI/CD pipelines in Azure DevOps (Pipelines, Repos), including environments and quality gates.
    + Familiarity with GitHub and GitHub Actions for reusable workflows, build/test/deploy automation and integration with platform tooling.
  • Automation and testing of infrastructure and platforms + Experience implementing automated testing for infrastructure and platform components, including IaC unit/integration tests, deployment validation, policy‑as‑code (Azure Policy, OPA) and IaC linting.
  • Security and compliance + Strong understanding of cloud and SaaS security best practices: least privilege, managed identities, secret management, network security, private endpoints, and secure software supply chain practices (image scanning, SBOM, dependency governance).
    + Awareness of compliance, data residency and multi‑region considerations in multi‑tenant Azure environments.
  • Technical leadership and communication + Ability to run proofs of concept with emerging technologies and present outcomes to both technical and non‑technical audiences.
    + Comfortable partnering with application teams to gather requirements and shape platform capabilities.
Other highly desirable, but not essential skills are

  • Kubernetes certifications (e.g., CKA, CKAD, CKS).
  • Degree in Computer Science, Engineering, Mathematics or equivalent industry experience.
  • Experience with high‑volume, low‑latency SaaS systems.
  • Experience with distributed and event‑driven architectures (Azure Service Bus, Event Hubs, Event Grid, Kafka).
  • Experience building multi‑tenant architectures, including tenant provisioning, routing and per‑tenant configuration/quota management.
  • Experience with Azure ingress and global routing solutions such as Azure Front Door, Application Gateway, and Azure API Management.
  • Experience with identity and access management using Azure AD/Entra ID, B2B, RBAC, OAuth2, OIDC, JWT and claims‑based authorisation.
  • Experience in platform engineering or SRE roles: building internal platforms, defining SLI/SLOs, managing error budgets, and implementing observability (centralised logging, metrics, distributed tracing).
