Job description

Company Overview

H2O.ai is on a mission to democratize AI for Good. As the world’s leading agentic AI company, H2O.ai converges Generative and Predictive AI to help enterprises and public sector agencies develop purpose-built Agents, SLMs, and solutions on their private data. With a focus on secure, compliant, and infrastructure-flexible Sovereign AI deployments, H2O.ai delivers solutions that align with the highest standards of data privacy and control.

Its open-source technology is trusted by over 20,000 organizations worldwide, including more than half of the Fortune 500. H2O.ai powers AI transformation for companies like AT&T, Commonwealth Bank of Australia, Wells Fargo, Bank of America, Workday, Progressive Insurance, and NIH.

About This Opportunity

We are looking for a Senior AI Engineer who builds things that matter. You will design and ship end-to-end AI solutions for some of APAC's most complex enterprise problems - spanning agentic AI systems, LLM applications, and production ML pipelines. This is a hands‑on engineering role embedded within a customer‑facing field team, meaning your work will be seen, used, and evaluated by real enterprises from day one.

Location: Sydney | Hybrid

Remuneration: Competitive salary package

What You Will Do

• Model distillation and synthetic data generation for fine‑tuning an open source model (eg. Gemma). Experience with PEFT‑QLORA frameworks
• Design and build agentic AI systems and multi‑agent frameworks that automate complex, multi‑step workflows for enterprise customers.
• Develop and deploy LLM‑powered applications using techniques including RAG, fine‑tuning, prompt engineering, function calling, and tool use.
• Implement guardrails, evaluation frameworks, and responsible AI controls to ensure production‑grade reliability and safety.
• Stay current with the rapidly evolving agentic AI landscape - MCP, LLM orchestration frameworks, reasoning models - and bring the best of it into customer engagements.

End‑to‑End AI Application Development

• Own the full development lifecycle: from problem framing and data exploration through model development, API integration, and production deployment.
• Build scalable backend services and APIs that expose AI capabilities to enterprise applications and workflows.
• Integrate AI models into customer environments - cloud, on‑prem, and hybrid - ensuring performance, stability, and maintainability at scale.
• Develop ML pipelines and LLMOps infrastructure that support continuous model improvement and monitoring in production.
• Work directly with customer data scientists, engineers, and business stakeholders to translate real‑world problems into AI solutions.
• Contribute to pre‑sales and proof‑of‑concept engagements - building fast, credible demonstrations that win technical trust.
• Communicate clearly across audiences: from detailed technical design reviews with engineering teams to outcome‑focused updates for business stakeholders.
• Collaborate closely with Program Managers, Solution Engineers, and Kaggle Grandmasters to deliver cohesive, high‑quality solutions.

What We Are Looking For

• 3+ years of hands‑on AI/ML engineering experience, including end‑to‑end model development and production deployment.
• Demonstrable experience building LLM‑powered applications - RAG pipelines, agentic workflows, fine‑tuned models, or similar.
• Strong Python engineering skills; experience with ML frameworks (PyTorch, TensorFlow, scikit‑learn) and LLM tooling (LangChain, LlamaIndex, or equivalent).
• Experience deploying models and AI services in cloud or enterprise environments (AWS, Azure, GCP, on‑prem Kubernetes).
• Deep understanding of modern GenAI concepts: prompt engineering, RAG, fine‑tuning, RLHF, model evaluation, guardrails, and LLMOps.
• Solid grounding in classical ML - able to select the right tool for the problem, not just default to the latest LLM.
• Backend development skills: REST APIs, containerization (Docker/Kubernetes), and CI/CD pipelines for AI applications.
• Strong problem‑solving instincts - comfortable with ambiguity, able to move fast without sacrificing engineering quality.
• Clear communicator who can explain complex AI systems to non‑technical stakeholders without oversimplifying.

How to Stand Out From the Crowd

• Kaggle or competitive ML experience.
• Familiarity with the latest H2O.ai products such as TabH2O, TimeH2O and Lightning‑JEV
• Experience in financial services, healthcare, or other regulated industry AI deployments.
• Exposure to tabular foundation models, AutoML, or enterprise ML platforms.
• Prior experience in a customer‑facing or field engineering role.

Why H2O.ai?

• Market leader in total rewards
• Remote‑friendly culture
• Flexible working environment
• Be part of a world‑class team
