About Woolworths Group & wiq

We are Woolworths Group, 200,000+ bright minds connected by a shared purpose: to create better experiences together for a better tomorrow. Through our partnership with Quantium, we have formed wiq—a powerhouse of data science and advanced analytics.

At wiq, we leverage Agile methodologies to solve the most complex problems in retail, from eCommerce and loyalty to supply chain and pricing. We are looking for a passionate Senior Data Scientist to join the wiq Marketing team and drive the next wave of AI innovation.

What You’ll Do

You will partner with the Group’s marketing teams to accelerate and optimise campaign creation strategies through cutting-edge AI.

• Architect Agentic Systems: Design autonomous, cyclic loops and multi-step reasoning systems (moving beyond linear prompting) to automate marketing workflows.

• Deploy Multi-Modal Solutions: Scale GenAI applications across Text (Advanced RAG), Audio (STT/TTS), and Video (e.g., Veo) to enhance creative output.

• Production-Grade Engineering: Architect scalable solutions and manage the transition from initial concept to formal production release.

• Advanced Evaluation & Observability: Implement frameworks using LangFuse and custom metrics to track tool-calling accuracy, trajectory, and goal completion.

• Strategic Problem Framing: Bridge the gap between technical possibilities and commercial outcomes, identifying where Agentic systems add the most value.

• Collaborative Innovation: Integrate embeddings and vector databases into live systems in collaboration with Product and Engineering.

What You’ll Bring

We are seeking a technically elite individual who balances AI architecture with a focus on production-ready code.

• Agentic Orchestration: Expert-level experience with LangGraph, LangChain, ADK, or PydanticAI. Proficiency in CoT, ReAct, Tree of Thoughts, and Multi-Agent handoffs.

• Multi-Modal Expertise: Hands-on experience with long-context RAG, fine-tuning, and audio/video generative models.

• Engineering Excellence: Expert Python and SQL skills; clean code advocate. Experience with React (prototyping) and PyTest/CI-CD (DevOps).

• Modern AI Stack: Familiarity with AI-assisted development (Claude Code, Gemini Copilot) and vector databases (GCP Vector Search, Qdrant).

• Solution Architecture: Ability to frame "big picture" business problems into viable technical roadmaps.

• Foundational Data Science: Deep understanding of embeddings, non-deterministic output interpretation, and metrics (Gini, Precision/Recall vs. LLM-as-a-judge).

• Stakeholder Leadership: High-level communication skills to translate complex logic into clear business recommendations.

• Proven Delivery: A portfolio of productionised systems (not just POCs or notebooks) deployed in cloud environments.

• Industry Context (Bonus): Background in Digital Marketing, AdTech, or E-commerce.

What You’ll Experience

• A global business with endless career possibilities around every corner and across every discipline – with valuable exposure to a vast and exciting business network.

• 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.

• 12 weeks paid parental leave for primary caregivers plus paid superannuation for up to 12 months while the Team Member is on parental leave - eligible from the first day of employment.

• A range of programs to help you prioritise and manage your wellbeing, including 24/7 access to the Sonder app. A progressive and competitive leave policy that gives you more space for what matters to you.
