Overview

Join to apply for the Principal Software Engineer role at Commonwealth Bank.

See yourself in our team. You'll join the Service Management Modernisation (SMM) Program, a strategic initiative driving DevSecOps transformation across the bank. Our mission is to simplify and automate operational processes, empowering service owners and engineers to focus on innovation. You'll work closely with a newly formed squad embedded in SRE Engineering, collaborating with a Product Manager and engineers across business units to solve real-world challenges through automation, data, and AI.

Responsibilities

• Lead the design and delivery of scalable AI and traditional solutions, guiding architecture and engineering strategy across cloud platforms.
• Drive modern engineering practices, including platform, prompt, and knowledge engineering, while fostering collaboration across technical and product teams.
• Build and scale GenAI capabilities, overseeing infrastructure for model fine-tuning, deployment, and monitoring.
• Automate and simplify operational processes using data, dashboards, and system integrations to improve efficiency and compliance.
• Champion data governance and quality, ensuring privacy, lineage, observability, and regulatory compliance in all development initiatives.
• Mentor engineering talent and communicate effectively, translating complex technical concepts for senior leadership and non-technical stakeholders.

Tech Skills

You will need to be across a broad range of tools, languages, and frameworks. Experience or exposure to some of these will set you up for success:

• Full-cycle development expertise in Python, TypeScript, and/or Golang, with strong experience building scalable microservices and RESTful APIs.
• Cloud-native engineering across AWS and Azure, including infrastructure design, platform reliability, and DevSecOps practices like CI/CD, IaC, TDD/BDD.
• Advanced AI/ML capabilities, with deep knowledge of GenAI, LLMs, and frameworks such as LangChain and Semantic Kernel.
• Data engineering proficiency, including distributed processing (Spark, Flink, Beam), data lakes/warehouses (Snowflake, BigQuery), and streaming platforms (Kafka, Kinesis).
• Database and testing expertise, covering vector/graph databases and non-deterministic testing approaches for robust data systems.
• Governance and architecture leadership, with experience in metadata management, data cataloging tools (Collibra, Alation), and customer engagement systems.
