Senior Platform Engineer

About the role The Adviser Platform (TAP) is a growing fintech business, offering New Zealand financial advisers a market-leading management platform. TAP is part of the wider BNB Group, which builds and supports a number of financial services and technology businesses. The Platform Engineer owns the foundation for which these sit on: the Kubernetes estate, the cloud infrastructure beneath it, and the tooling that enables our engineers to ship safely without needing to become infrastructure experts. We're hiring a Senior Platform Engineer to own significant parts of that platform end to end. This is a build role, not a ticket-queue role. Our internal users are engineers, we treat the platform as a product they choose to adopt. You'll spend your time roughly split between running and evolving our Kubernetes and cloud infrastructure, and building the self-service layer on top of it - golden paths, templates, pipelines, and internal tooling that make the correct way to do something also the easiest way. What you'll do Kubernetes and cloud infrastructure Own and evolve our multi-cluster Kubernetes environment across [dev / staging / production] - upgrades, capacity, workload isolation, multi-tenancy, and cluster lifecycle Design and maintain cloud infrastructure on AWS + Azure as code, including networking, IAM boundaries, and account or landing-zone structure Build and maintain reusable Terraform (or Cloudformation / Bicep etc) modules that product teams consume, with sensible defaults and guardrails baked in Improve resilience: autoscaling, failure isolation, DR posture, and the operational runbooks that go with them Manage the platform's own operational health - cost, performance, and capacity - and bring visibility to the teams generating the load Developer experience Build and extend the internal developer platform: service scaffolding, self-service provisioning, and CLI tooling Define golden paths for common needs - a new service, a new environment, a new datastore - so teams get a secure, observable, deployable starting point in minutes rather than weeks Own CI/CD as a product: pipelines, build performance, artifact management, and progressive delivery patterns such as canary and blue/green Make observability a default rather than an afterthought, with instrumentation, dashboards, and alerting available out of the box Write the documentation, run the office hours, and gather the feedback that turns a platform into one people want to use Working across the organisation Partner with product engineering teams to understand where the friction actually is, and prioritise accordingly Work with Engineering leaders to embed policy-as-code, secrets management, and supply chain controls into the paved road rather than bolting them on Participate in the platform on-call rotation, lead incident response for platform-owned services, and drive blameless postmortems to real fixes What we're looking for Required 5+ years in platform, infrastructure, DevOps, or SRE roles, including meaningful production Kubernetes ownership (not just deploying to someone else's cluster) Strong infrastructure-as-code practice with Terraform or equivalent, including module design for other teams to consume Deep working knowledge of at least one major cloud provider - compute, networking, IAM, and managed services Proficiency in at least one general-purpose language (.net, node or similar) - enough to build tooling, not only to script around it Hands-on experience designing and operating CI/CD systems at scale Solid grounding in observability practice: metrics, logs, traces, and alerting that people actually trust Track record of operating production systems under real reliability expectations, including on-call Clear written communication, and the judgement to work with internal customers rather than around them Nice to have Working in a regulated environment - [SOC 2 / ISO 27001 / PCI-DSS / HIPAA] Experience with a large-scale migration: monolith decomposition, cloud migration, or a platform consolidation We Offer Competitive remuneration that reflects your experience Hybrid model - 2 days per week in our Auckland/Christchurch office A supportive and collaborative team environment Apply Now!
