Platform Engineer (SDE3)

The Opportunity

As a Senior Platform Engineer (SDE3) at NAB, you will be a technical leader, architect, and mentor, driving the evolution of the core platforms that power our entire engineering organization. This role moves beyond feature delivery to owning the design and implementation of large-scale, resilient, and secure systems. You will tackle complex technical challenges, such as building ephemeral on-demand environments from scratch, optimizing our multi-cloud Kubernetes strategy, and embedding security deep within the software development lifecycle. You will have a significant impact not only on our technology but also on our colleagues, actively mentoring junior engineers and fostering a culture of technical excellence. If you are a seasoned engineer passionate about building world-class platforms and leading by example, this is your opportunity to shape the future of banking technology.

What You'll Do

As a SDE3, you will be responsible for the architecture and delivery of critical platform capabilities, ensuring they meet the highest standards of security, scalability, and reliability.

• Lead Technical Design and Architecture : Lead the architectural design and implementation of major platform initiatives. You will be responsible for creating robust, scalable, and secure solutions that solve complex problems for our internal development teams.
• Build Risk-Mitigated Financial Systems : Architect and build highly available and fault-tolerant systems that meet the stringent security, compliance, and risk mitigation requirements of a large-scale financial institution.
• Drive DevSecOps Adoption : Champion and implement DevSecOps best practices across the platform. You will design and integrate automated security scanning, policy enforcement, and compliance checks directly into our CI / CD pipelines to create a secure-by-default environment.
• Master Multi-Cloud and Kubernetes : Act as a subject matter expert on our multi-cloud (AWS and Google Cloud) infrastructure and our enterprise-scale Kubernetes platform. You will drive improvements in scalability, performance, and cost-efficiency.
• Define and Manage Reliability : Define, measure, and evolve platform Service Level Objectives (SLOs) and error budgets, using data-driven approaches to balance innovation speed with operational stability.
• On Demand Environments : Design advanced ephemeral environments with intelligent resource management and cost optimization
• Mentor and Develop Talent : Actively mentor SDE1 and SDE2 engineers through design reviews, code reviews, and pair programming. You will play a crucial role in leveling up the technical capabilities of the entire team and fostering an inclusive, learning-based culture.
• Influence Technical Strategy : Collaborate with architects and other senior engineers to influence the technical direction of the NAB Engineering Foundation, evaluating new technologies and advocating for best practices.
