Stax is a home-grown start-up revolutionising the AWS cloud experience. Our aim is to provide a platform that automates and streamlines critical tasks to provide a secure and efficient developer experience. Founded by the cloud experts at Versent, Stax has grown to a team of 40 cloud artisans passionate about the quality outcomes we deliver. With over 200 active customers across 3 continents, our customers range from fast food, to luxury, to ASX top 20.

We've cultivated an environment based on creativity. When people who care about their craft are given the freedom to explore possibilities without restriction, amazing things can happen. There are no cool cliques, just a hard-working team generating ideas and devising solutions in a creative, collaborative workspace. 

We're going through a period of massive growth, and we're not slowing down. We're looking for Site Reliability Engineers (SRE) to join our ranks and work alongside a team made of engineers, developers, IM's and PO's. You will have the opportunity to learn from some of the brightest minds in the industry!

The SRE practice at

“SRE is what happens when a Software Engineer is tasked with what used to be called Operations.” The SRE practice has been embraced since the early stages of Stax.

The Stax SRE team is a multidisciplinary group of Software and Systems engineers with a focus on reliability, driven by SLOs. 

We’re building a team with engineers from a wide variety of backgrounds, experiences, and perspectives. Diversity, intellectual curiosity, problem-solving, and openness is key to our success. We encourage collaboration, thinking big, and taking risks in a blame-free environment. 

We promote self-direction to work on meaningful projects. At the same time, we also strive to create an environment that provides the support and mentorship needed to learn and grow.

What do SREs do?

·       Observability: build and combine monitoring and data analytics tools (metrics, logging, tracing, big data) to measure our customers’ experience and reflect that back into the product development cycles.
·       Incident Management: technical support and troubleshooting of live production systems, facilitate the response to emergencies, bring the systems back online as quickly as possible. Take part in the on-call roster with our development teams to support the services after regular office hours.
·       Postmortems: bring a blameless culture, learn from failure, provide and implement recommendations to improve reliability, ensure high SLO attainment.
·       Testing & Release Process: ensure the services delivered to customers are reliable, scalable, maintainable, and consequently will meet the SLOs. 
·       Capacity Planning: measure and report on systems capacity to guarantee service reliability over time as load increases or decreases.
·       Development: system architecture and software development projects for the SRE needs, or as part of a development team. Provide development standards, and promote reusability, reduce complexity to improve reliability. Automate, automate, automate.
·       Product: Consult in service architecture and design conversations. Liaise directly with the customer success team. Facilitate the feedback loop between customers and product teams.

How do we do as a SRE?

At, we adopted the SRE “kitchen sink” implementation. While the SRE practice can spread across all topics and services, SREs also manage their workload based on SLOs and, ultimately, business needs.

·       SRE Projects: architecture and development work for the needs of SRE foundations. Build SRE services consumed by the Product team.
·       Tooling: Strong focus on implementing tools to assist with the reliability of product development.
·       Embedded: working directly as a developer as part of a product team with a focus on implementing SRE practices and tools.
·       Consultation: act as a consultant across several projects to assist with the end-to-end lifecycle of Stax services.
