We provide targeted omnichannel marketing solutions and comprehensive closed loop reporting to help brands grow.

With Cartology, brands can drive real customer impact across the shopper journey.

Cartology is truly pioneering the future of Retail Media, creating, shaping and leading this new industry that connects brands to customers in new and exciting ways.

Be nothing but yourself in a culture that is inclusive and innovative.

Work as part of an ambitious, smart and passionate team and belong to something meaningful as part of the Woolworths Group.

The Opportunity

As a Staff Engineer you will hold the architectural line across Ads Manager as it scales.

You will own the architecture of a critical part of the platform, spanning the event driven services that carry campaign, creative and audience data through to delivery and measurement, and you will be accountable for that architecture staying scalable, observable and comprehensible as the surface area grows.

This is a technical leadership role rather than a management one.

You will spend real time in the code, and your impact will be measured as much by the engineers and systems you lift as by what you personally ship.

What You'Ll Do

Architectural Ownership: Own and evolve the architecture of one or more critical systems within Ads Manager, making the significant decisions that hold across multiple teams and driving the technical roadmap for your area
Campaign Orchestration and Distributed Systems: Act as the subject matter expert for message oriented, event driven design, and design the durable, long running processes that coordinate state between our platform and third party adtech systems

Typically 10+ years in software engineering, with recent time operating at Staff, Principal or Lead level. With weight evidence of scope, being the systems you have owned and the decisions you made, more heavily than years served
Deep expertise in Kotlin and/or Java, including JVM concurrency and memory behaviour, and fluency in a modern framework such as Spring Boot, Micronaut or Ktor
Expert level knowledge of message oriented architectures, including delivery semantics, idempotency, ordering, backpressure and failure recovery
Hands on experience with Google Cloud Platform, specifically Kubernetes (GKE), Cloud SQL for PostgreSQL and BigQuery, or comparable depth on AWS or Azure
Working proficiency in TypeScript and React, sufficient to review meaningfully and contribute when it matters
A track record of building resilient integrations with third party platforms you do not control, including reconciliation, retry and drift detection
Expert with Git and automating complex delivery workflows in GitHub Actions, with a genuine “you build it, you run it” mindset

What you’ll Experience

Team Discounts - Team discounts across our range of Woolworths Group brands you know and love and a robust rewards program that celebrates and incentivises purpose-driven work.
Wellness - Access to Sonder. Sonder provides free confidential 24/7 personalised financial, medical safety, psychological or physical support for team members and their families.

Everyone belongs at Woolworths Group As one of the largest employers in Australia and New Zealand, we aim to create a truly inclusive workplace where everyone feels that they belong, can be their best selves, and reach their full potential.

Diversity, equity, inclusion, and belonging are key to realising our purpose of better together for a better tomorrow.
