How will you make an impact?

Our platform handles sensitive financial data for hundreds of thousands of Australians. That means the infrastructure we run must be secure, reliable, resilient and fast. The engineer who owns it must be exceptional. That's where you come in.

Reporting directly to the Head of Technology, you will be the technical authority for Wisr's cloud infrastructure and platform engineering discipline. You'll own the reliability, security posture and scalability of our infrastructure, working across cloud providers with full autonomy to make and execute architectural decisions that matter.

You'll set direction, shape standards, and work closely with product engineers to ensure everything we ship is built on infrastructure they can trust.

Design and evolve our multi-cloud infrastructure (Azure, AWS and GCP)
Maintain platform reliability, building scaling systems, automation and optimisation of our technology stack.
Champion infrastructure-as-code practices across the organisation, using IaC tools (Pulumi) to manage the lifecycle of underlying Azure resources and deploying applications on top of it.
Build and maintain an internal developer platform that enables engineers to ship faster and with greater confidence.
Define and own SLOs, own standards for CI/CD, environment management, containerisation, and observability.
Continuously seek and implement automation opportunities, leveraging modern SRE tools to automate operational tasks, speeding up delivery of applications and services thereby increasing team efficiency and the SRE process for our squads.
Monitor, detect and address system issues by creating strategies and designing systems to automatically troubleshoot.
Influence architectural decisions across the broader engineering team. Write RFCs, participate in design reviews and mentor software engineers at all levels.
Partner with the Head of Technology on roadmap and strategy.
Work closely with the Cybersecurity squad to create a comprehensive Disaster Recovery strategy and perform periodic DR drills.
Lead incident response and post mortems with a blameless, systems-thinking mindset. Eliminate toil through automation and champion operational maturity across the engineering organisation.
Embed security across the entire software delivery lifecycle and not as an afterthought, driving a zero-trust architecture.
Manage external vendor relationships and ongoing subscriptions related to the platform.

You own incidents end-to-end and you're not afraid to push back when a decision puts reliability or security at risk. Above all, you are a coach at heart, and thrive when sharing your knowledge with others.

Experience working within a fintech or financial services environment ideal.
Experience working with and strong expertise with container and orchestration tools such as Docker, Container Registries, Kubernetes (EKS, GKE, AKS) and Helm.
SRE expertise: SLOs, error budgets, chaos engineering, mature on-call practices, blameless post-mortems.
Observability stack experience such as distributed tracing, log aggregation, metrics and alerting (Datadog, Grafana/Prometheus).
Strong networking fundamentals VPNs, private endpoints, DNS, CDN, and load balancing
Mastery of infrastructure-as-code tooling, Pulumi and GitOps at scale.
Strong security engineering foundations, zero-trust networking, IAM, secrets management, SIEM, vulnerability scanning.
You have knowledge that spans both development and operations including coding, infrastructure management and engineering.
