Lead AWS Platform Engineer

Hi, we’re PEXA! We revolutionised the way that property is settled in Australia, turning a paper-based process into a digital one. Our solution is a world-first, with over 500 people across Australia and an expanding international team, helping 20,000+ families into their homes each week. We’re passionate about solving problems for our customers – always striving to set the standard for how property is bought and sold.

We’re growing fast, that is where you come in. We believe our success in Australia is worth sharing and that our proven technology will advance how the UK buys and sells homes. Establishing ourselves within the UK in late 2020, we are committed to collaborating with lawyers, conveyancers, lenders, government and the property industry, to set the new standard for both remortgages and buying and selling property.

Help shape the platform behind PEXA Go

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.

What You’ll Do

• You’ll help deliver the platform roadmap, balancing planned improvements with operational needs.
• 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.

What You’ll Bring

• You’ll have strong experience building and operating production platforms in AWS, and be comfortable taking complex engineering work from design through to delivery.
• Practical expertise in EKS, Kubernetes, AWS networking, identity and access management, storage, databases and managed messaging.
• 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.
• The judgement to balance delivery pace with reliability, security, supportability and cost.
• Clear communication and a collaborative approach to working across technical teams.

Experience with platforms such as Kong or Unleash, or in financial services or another environment with demanding resilience and assurance requirements, would be useful.

How You’ll Work

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.
