• Strong Terraform experience, including modules, testing, version control and state management
• Experience with CI/CD and secure deployment practices
• A good understanding of high availability, backup, disaster recovery, failover and capacity management
• Experience with monitoring, logging, tracing and actionable alerting
• Knowledge of cloud security, vulnerability management and cost optimisation

What the job involves

• We’re looking for a hands-on Lead AWS Platform Engineer to join the PEXA Go team. You’ll help shape the platform’s strategy and architecture, then turn that direction into reliable, secure and well-supported infrastructure
• This is a strong individual contributor role. You’ll work closely with platform and software engineers, product teams and operational colleagues, bringing the technical ownership and follow-through to keep platform work moving
• You’ll help deliver the platform roadmap, balancing planned improvements with operational needs. That means getting involved in the detail: designing and deploying infrastructure, managing upgrades, improving automation and resolving complex technical issues
• Turn platform strategy, architecture and standards into practical plans and working solutions
• Design, build and improve AWS services that support PEXA Go, including EKS, RDS and Aurora, MSK, S3, IAM and core networking
• Develop and maintain infrastructure as code using Terraform, along with the pipelines that deploy it
• Plan and deliver platform upgrades, lifecycle work and technical improvements
• Improve platform reliability, resilience, security, observability and cost efficiency
• Work with engineering and operational teams on safe deployments, incident response and service readiness
• Share technical direction through design reviews, code reviews, troubleshooting and practical collaboration
• Keep documentation, operating procedures and architecture records up to date
• Take part in the paid platform engineering on-call rota
• You’ll be self-sufficient and comfortable taking the lead on platform activity, while working as part of a wider team. You’ll bring a point of view on strategy and architecture, make sound technical decisions within agreed guardrails, and involve the right people when a decision has wider implications
• There are no direct reports currently. Your focus will be hands-on engineering, technical leadership and helping the platform capability develop as the team grows
