Platform Engineer

• Own 5 AWS accounts across the organisation (QA, Prod, Infra, plus two others)
• Architect and maintain infrastructure as code with Terraform. Replace the click-ops that's still around
• Stand up CI/CD pipelines engineers actually want to use. Blue/green and canary where it makes sense
• Run releases reliably and reduce key-person risk on the deploy process
• Set up monitoring, alerting, and incident response so we catch issues before customers do.
• Define SLIs and SLOs that map to real user journeys
• Lead incident response as the primary infra responder.
• Run blameless post-mortems
• Patch and harden the platform. We're a fintech, this matters. IAM least privilege, secrets management, vulnerability scanning, MFA enforcement
• Lead infrastructure work for the TV launch: traffic spikes, autoscaling, capacity planning, runbooks
• Partner with backend engineers when production issues cross into the app tier. JVM tuning, connection pools, async patterns, memory leaks
• Architect multi-region DR.
• Drive the platform toward self-healing
• Optimise cost across DynamoDB, Lambda, and the wider AWS footprint
• Set architectural guardrails with tech leads and SWEs.
• Mentor engineers as the platform capability grows.
