About This Opportunity
We are looking for a Senior Data Scientist who thrives at the intersection of cutting-edge AI and real enterprise impact. You will work directly with some of APAC's most sophisticated organisations - helping them move from AI curiosity to AI value, across the full spectrum of predictive and generative AI.
This is not a lab role. You will be in the room with executives, data science teams, and business stakeholders - building solutions, running enablement programs, and translating complex AI into outcomes that decision-makers can act on. You will be backed by a world-class team including Kaggle Grandmasters, and equipped with H2O.ai's industry-leading platform spanning AutoML, LLM Studio, and agentic AI tooling.
This position is based in Sydney, Australia.
What You Will Do
- Partner with stakeholders to deliver data-driven AI/ML solutions across industries such as banking, insurance, retail, healthcare, and manufacturing.
- Build, validate, and deploy predictive ML models for forecasting, classification, optimisation, and anomaly detection.
- Apply statistical and ML techniques (regression, trees, ensembles, time series, clustering) based on business needs.
- Explore GenAI approaches where relevant, including LLMs, SLMs, RAG, prompt engineering, and basic agentic workflows.
- Perform end-to-end data science work including data exploration, feature engineering, modelling, evaluation, and interpretation.
- Translate model outputs into actionable insights for business stakeholders.
- Collaborate with engineering teams on model productionisation.
- 4+ years of experience in data science, machine learning, or applied AI roles.
- Strong predictive ML foundations (feature engineering, model selection, evaluation, interpretability).
- Experience working with real-world datasets and business problem framing.
- Exposure to GenAI: LLMs, SLMs, RAG, prompt engineering, or agentic workflows.
- Strong Python skills.
- Understanding of deployment/MLOps concepts.
- Strong communication, storytelling and presentation skills.
How to Stand Out From the Crowd
- H2O product experience.
- Kaggle competition experience or equivalent applied ML work.
- Cloud or production ML exposure.
- A/B testing or causal inference experience.
- SLM or agentic AI exposure.
- Open-source, research, or technical writing.
- Client-facing experience: scoping problems, managing expectations, and delivering solutions with customer teams.
