Staff Site Reliability Engineer

About the team:

The Platform SRE team at Luno owns the full infrastructure stack - from Kubernetes and AWS through to CI/CD, observability, networking, and developer tooling. We work with high autonomy, balancing business initiatives, platform improvements, and the reliability work that keeps a global financial platform running. We build for the future and enable developers to deliver now. We are spread across the world and operate in a remote-first environment, where collaboration and communication is crucial day-to-day. The role in a nutshell:

As a Staff SRE at Luno, you are providing technical expertise and oversight for reliability and scalability across our cloud estate. Joining a high-impact team, you will help shape the future of our platform while partnering with teams throughout the engineering organisation to scale reliability and accelerate delivery.

You’ll help manage multi-region Kubernetes and AWS at scale within a regulated financial environment - where uptime is critical. Beyond solving complex problems, you’ll define the technical roadmap, prioritize high-impact initiatives, and lead their execution. Your mission will be: • Owning and driving large-scale platform initiatives from problem definition through to delivery - setting technical direction, aligning stakeholders, and seeing projects through • Shaping how the Platform team builds and operates: from architectural standards to how we respond when things go wrong. • Building and scaling infrastructure and CI/CD processes on the Luno platform by applying and enforcing Infrastructure as Code. • Apply security first principles when building - ensuring compliance with various security and legal audits that we apply for and encounter in the crypto industry. • Contributing to the team's long-term roadmap while staying hands-on - this is a role that requires both strategic thinking and the ability to go deep. • Increasing AI adoption throughout the Platform team and engineering as whole, identifying opportunities to improve how we work and increase efficiency. A little about you: • You're energised by hard infrastructure problems and take pride in solving them properly, not just quickly • You’re comfortable influencing team decisions without direct ownership, using data, clear reasoning and pragmatic choices. • You're comfortable with ambiguity and are able to bring structure to it through research and requirements. • You communicate clearly and directly with both technical and non-technical stakeholders - recognizing that written context is just as important as the work itself. • You’re curious by nature and motivated to keep learning as tools, techniques and the platform landscape evolves. • You have an active interest in AI tooling and emergent technologies. The ideal Lunaut will have: • Deep, hands-on experience in a Site Reliability, Platform, DevOps, or Infrastructure engineering role. • Strong AWS knowledge, with experience architecting and operating multi-account, multi-region environments. • Production-grade Kubernetes experience: building, running and scaling clusters with strict uptime requirements. • Extensive experience with observability and monitoring tooling to support live services. • Experience partnering with cross-functional teams to scope, design and implement business-lead projects. • Demonstrable experience in managing large infrastructure projects using Terraform • Experience leveraging AI tools to increase team productivity - from infrastructure automation, to improving operational workflows. • Remote but reachable work policy gives you the freedom to choose between working from home or the office. • Plus the option to buy and sell up to 5 days leave • Improve body and mind, with excellent private medical insurance • Access to Learnably and our additional learning platforms for your personal and professional development • 6 months primary care-giver leave • Paw-ternity leave for your furry friend • Annual Inspiration Day in addition to your annual leave which increases based on your length of service • A collaborative, friendly work community, with regular social events and virtual cooking, dancing, drawing and house planting classes hosted by our Lunauts • 0 fees up to a certain amount
