Job description

Location: United Kingdom

Hi, we’re PEXA!

We know you’ll Google us before applying, so let’s keep this brief. PEXA 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, we’re 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. Being awarded as one of the best places to work in Australia is a recognition of our culture and commitment to innovation, customers and our community.

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. That means getting involved in the detail: designing and deploying infrastructure, managing upgrades, improving automation and resolving complex technical issues.

You’ll:

• 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.

You’ll also bring:

• 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.

Why become a PEXArian?

Great question! Being a PEXArian is so much more than just a job. We’re a passionate, motivated and unashamedly enthusiastic bunch at PEXA – we love what we do and we’re proud to admit it! Creating brilliant experiences for our members and their clients wouldn’t be possible without ensuring we deliver an exceptional employee experience.

Here’s a snapshot of what your life at PEXA could look like:

Your wellbeing:

Enjoy four Wellness Days across the year to rest and recharge, plus 24/7 personal safety, medical and mental health support through Sonder. You’ll also receive an £800 Health Flex Pot to spend on health options, alongside access to a digital GP, mental health and nutrition consultations, and support with eye tests and glasses.

Your growth:

Grow your skills and shape your career through PEXA Academy and LinkedIn Learning. You’ll also have up to five days’ paid study leave each year for relevant courses.

Your rewards:

Our reward and recognition benefits include performance‑based incentives, the PEXA OwnIt Equity Plan for eligible employees, PEXA Impact Awards and a £500 employee referral bonus. You’ll also have access to discounts through Perkbox and Get Active.

Your family:

Eligible permanent employees with at least 12 months’ continuous service can receive up to 20 weeks’ paid maternity or adoption leave and up to four weeks’ paid paternity leave, in addition to statutory entitlements. You’ll also have access to support for family and life events, including family grief counselling, discounted legal services and UK‑registered veterinary advice.

Your work/life blend:

We know that work is just one aspect of your life – we want to help you create your ideal work/life blend, rather than squeezing in life around work. Our hybrid approach combines regular in‑office connection with working from home. You may also be able to work remotely from an approved country for up to two weeks every six months and purchase up to four additional weeks of annual leave each year.

Your opportunity to give back:

Use your paid Volunteer Day to support a cause that matters to you and enjoy events throughout the year that bring PEXArians together to connect and celebrate.
