Senior DevSecOps Engineer - Service Mesh and API Security

About Trideca Trideca is Australia's trusted strategy, AI, and digital transformation partner, helping some of the nation's largest enterprises (including NAB, Suncorp, Optus, Medibank, and AGL) drive meaningful business impact through technology. With offices in Melbourne and Sydney and projects spanning multiple industries, we thrive on solving complex challenges, delivering cutting-edge solutions, and pushing the boundaries of what's possible. Trideca is partnering with a leading Australian financial services organisation on a major uplift of its internal application security. The program centres on the rollout of a new enterprise service mesh that will strengthen security and give the organisation greater control over how its internal applications communicate. We are looking for experienced DevSecOps specialists who can get moving quickly and help drive the rollout across the client's GCP environment. The Role You will help deploy and expand the service mesh across GCP clusters, building and configuring security policies for APIs and for communication between applications. A core part of the role is helping delivery teams adopt the platform and meet a tiered set of API security standards. Along the way you will identify gaps in API and microservice security compliance. You will work closely with security, platform and delivery teams to put improvements in place, support the creation and rollout of a registry of APIs and microservices, and contribute to policy enforcement that may ultimately stop systems that fall short of those standards from being deployed. About You You bring a strong DevSecOps background and experience at a senior level with cloud platforms, ideally GCP. You have practical experience deploying and operating enterprise service mesh platforms such as Istio across multiple clusters. You have designed, implemented or managed API security policies and are comfortable working across microservices, APIs and distributed systems. You work independently in complex enterprise environments and communicate clearly, consulting across multiple delivery teams and explaining technical requirements in a way that turns them into practical outcomes.It would be highly regarded if you also have experience with Envoy or with replacing or migrating an existing service mesh, exposure to API discovery or monitoring tools such as Traceable, and familiarity with eBPF agents, Kong, CI/CD pipelines and policy as code. Experience in financial services, or with security compliance standards and uplift programs, would also be valued. Why Choose Trideca?
