omaze - Senior Platform Engineer

• Own the design, implementation, and evolution of Omaze's cloud infrastructure on AWS, Lambda, API Gateway, and surrounding services, written and maintained as code using CDK and / or Terraform. • Build and maintain CI/CD pipelines in GitHub Actions that are fast, reliable, and give engineers confidence to ship frequently and safely. • Drive observability across the platform via instrumentation, alerting, dashboards, and on-call tooling so the team can detect, diagnose, and resolve incidents quickly. • Own security and compliance posture across the infrastructure: IAM, secrets management, network boundaries, and regulatory requirements, identifying risk early and remediating it properly. • Identify and act on cost optimisation opportunities, tracking resource utilisation, rightsizing infrastructure, and making spend visible and understandable across engineering. • Raise the baseline for developer experience by reducing toil, improving deployment workflows, and making the right way to do things the easy way. • Hold a high bar in infrastructure code review by giving feedback that's direct, constructive, and focused on long-term maintainability and security. • Use AI-assisted tooling as a natural part of your workflow and apply the same rigour and judgement to AI-generated infrastructure code as you would to anything hand-written.
