Staff Engineer Chapter Lead – Generative AI

Location: Sydney CBD Area

Time Type: Full time

Job Description

Build AI that genuinely matters — for millions of Australians.

At CommSec, we’re transforming how customers and colleagues experience financial services through intelligent, responsible, and scalable Generative AI. As part of our mission to achieve NPS +30, we’re investing deeply in AI platforms, GenAI applications, and the people who build them.

We’re looking for a Staff Engineer Chapter Lead – Generative AI to shape the future of AI at CommSec. You’ll lead with empathy and technical excellence, build production‑grade GenAI systems, and help grow a team and culture where people can do their best work.

Why this role is different

This is not a research‑only role — and not a people‑manager‑only role either.

You’ll:

• Lead the delivery of high-impact GenAI systems that improve real customer and colleague experiences

• Set engineering standards for enterprise‑grade AI in one of Australia’s most trusted brands

• Grow and support people, creating a culture of inclusion, psychological safety, and technical ownership

• Build systems that last, with strong foundations in MLOps, evaluation, observability, and security

What you’ll do

Build and scale Generative AI

• Design, build, and operate production‑grade AI, GenAI, and Agentic AI systems

• Develop reusable frameworks and foundational capabilities for enterprise GenAI adoption

• Deliver Retrieval‑Augmented Generation (RAG) and agentic workflows that integrate with existing platforms

• Apply machine learning, NLP, and advanced analytics to solve complex, real‑world problems

Ensure quality, safety, and reliability

• Establish robust AI and LLM evaluation frameworks to ensure transparency and data‑driven decisions

• Embed strong MLOps practices across the full AI lifecycle

• Champion automation across development, testing, deployment, and cost optimisation

• Drive adoption of CI/CD, infrastructure as code, observability, and security best practices

• Participate in on‑call support as needed to keep systems running smoothly

Lead people and culture

• Lead and support a close‑knit, growing group of engineers, helping them thrive technically and professionally

• Foster autonomy, trust, and constructive challenge in a psychologically safe environment

• Coach, mentor, and encourage continuous learning and peer collaboration

• Communicate clearly with senior leaders and stakeholders, balancing outcomes, risks, and trade‑offs

What you bring

You don’t need to tick every box — we value capability, curiosity, and willingness to learn.

Technical strengths

• Strong Python experience across AI/ML and backend development

• Hands‑on experience with Generative AI and Agentic frameworks (e.g. LangChain, LangGraph, LlamaIndex, AutoGen)

• Production experience with RAG and vector databases (e.g. Pinecone, Weaviate)

• Solid grounding in ML engineering and MLOps

• Experience building APIs and integrating services

• Deep familiarity with AWS, Infrastructure as Code (CloudFormation or CDK), Docker, and Kubernetes

• Experience with CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins)

• Understanding of AI evaluation, monitoring, security, and governance

How you work

• You enjoy leading through influence and example

• You communicate clearly with both technical and non‑technical audiences

• You care about building inclusive teams and high‑quality systems

• You balance pragmatism with long‑term engineering excellence

Inclusion, flexibility, and support

At CommBank, inclusion isn’t an initiative — it’s how we work.

We encourage applications from people of all genders, backgrounds, abilities, and experiences. If you’re excited about the role but don’t meet every requirement, we still want to hear from you.

We offer:

• Hybrid working, with flexibility in how and where work gets done

• Support for different working patterns, including flexible hours, part‑time, and job share

• An inclusive, respectful culture where everyone belongs

If you need adjustments or support during the application process, we’re here to help.
