Senior Platform Engineer

At Pet Circle, we believe pets deserve the very best, and the people who love them deserve a better way to care for them. Since 2011, we've grown from that single idea into Australia's biggest online pet retailer, with around 500 Pet Circlers across Australia, New Zealand and the Philippines, reshaping how pet parents discover, choose and receive what their pets need.

Pet care is a $15 billion industry in Australia, and as pet ownership continues to grow, so do the expectations of modern pet parents. They want expert advice, personalised experiences, convenience and reliability, all delivered seamlessly. That's where we come in. We're building the future of pet care through technology, innovation and a deep understanding of what pets and their people need. It's a big opportunity, and we're only just scratching the surface.

The role

As a Senior Platform Engineer, you'll build the cloud infrastructure, tooling and CI/CD pipelines that Pet Circle's engineering squads ship on, so they can deliver at speed on a platform they can trust. This is a building role, not a run-and-maintain one: you'll design for scale on Google Cloud Platform, automate what used to be manual, and own your area broadly. You’ll report to the Director of Technical Operations while partnering closely with the engineering squads, Staff Engineers and Tech Leads who build the product.

What you’ll be working on

Build Pet Circle's cloud infrastructure on Google Cloud Platform, designing for scale, reliability and security

Drive infrastructure-as-code with Terraform (Pulumi is transferable), so the environment is reproducible and auditable

Build, maintain and speed up the CI/CD pipelines the engineering squads deploy through

Containerise and run services with Docker

Own observability, monitoring, alerting and logging, so issues are understood before they reach customers

Embed with the engineering squads, understand their friction points, and build a platform roadmap that makes shipping easier

Strengthen Pet Circle's security and disaster recovery, security assessments, vulnerability remediation, identity and access (Google Identity Platform, JumpCloud or similar), and tested recovery objectives

Identify high-risk legacy components and plan their removal

Get our CI/CD, observability and security ready for the AI features going into the product

Support cloud cost efficiency, right-sizing and optimising GCP spend

Respond to production incidents and lead the follow-up, so the same problem doesn't happen twice

What we're looking for

Deep, hands-on Google Cloud Platform experience, this is a must

Strong with Cloudflare, it's used heavily here, so little or no exposure is a real gap

You're already using AI in how you work and keen to do more, whether that's writing infrastructure code, debugging pipelines, analysing logs or generating runbooks.

Infrastructure-as-code in production with Terraform (Pulumi is transferable), including the messy parts like state management

CI/CD pipelines real teams deploy through, GitHub Actions (GitLab is transferable)

Hands-on with Docker (Kubernetes is fine but not required, we don't lean on it)

Knowledge of Python is preferred

You've built and improved security and disaster recovery, not just run tools, and least-privilege thinking comes naturally (JumpCloud and CrowdStrike experience is a plus)

An experienced engineer who's seen things go wrong and learned by doing, and who's energised by building the platform, not just running it

Comfortable in a lean team, owning broadly rather than specialising narrowly

You communicate clearly with both engineers and non-technical stakeholders, and partner well across teams

Where you'll work

This is a Sydney-based role. Our office sits on top of Wynyard station, it's pet-friendly (of course), and we work flexibly, a mix of office and home. We believe spending time together in person is important for building strong relationships, collaborating effectively, moving quickly as a team, and having fun!

A few good things

Heaps of development opportunities - lunch & learns, secondments & unlimited learning courses via Go1

Flexible working environment

Up to 50% employee discount

Product sample giveaways

Pawrental leave and wellbeing leave

Volunteer days for the causes you care about

Fitness corporate partnership

Why you'll want in

Looking after pets, and the pet parents who love them, is what gets us out of bed. That energy carries into how we work, and into what your days here would feel like.

You'll own your patch and have the room to act on it. We move fast and decide fast, and we'd rather test an idea and learn from it than sit on it. You'll have rich, real-time data at your fingertips to back your thinking, and the freedom to chase an opportunity the moment you spot one. The best idea wins, wherever it comes from.

What holds it together is what we stand for:

We're better together

We operate with humble hearts and hungry minds

Pets matter, so pets and pet parents always have a seat at our table

We're instinctively curious. Always

Everyone (& their pets) Welcome

We're better when we don't all think the same. Different backgrounds, perspectives and experiences make our work sharper and our days more interesting, so whoever you are, if this role excites you we'd love to hear from you, even if you don't tick every box. And if you need anything adjusted in the process to do your best, just say the word, we're happy to help.
