About the job
Google's software engineers develop the next-generation technologies that change how billions of users connect, explore, and interact with information and one another. Our products need to handle information at massive scale, and extend well beyond web search. We're looking for engineers who bring fresh ideas from all areas, including information retrieval, distributed computing, large-scale system design, networking and data storage, security, artificial intelligence, natural language processing, UI design and mobile; the list goes on and is growing every day. As a software engineer, you will work on a specific project critical to Google's needs with opportunities to switch teams and projects as you and our fast-paced business grow and evolve. We need our engineers to be versatile, display leadership qualities and be enthusiastic to take on new problems across the full-stack as we continue to push technology forward.

With your technical expertise you will manage project priorities, deadlines, and deliverables. You will design, develop, test, deploy, maintain, and enhance software solutions.

Domain Applied ML (DAML) operates as Google's "Applied AI Layer," architecting the technical bridge between Google DeepMind's frontier research and massive-scale product deployment. We define the company-wide strategy for Foundation Model adoption and engineer high-performance solutions in critical domains.

In this role, you will pioneer the next generation of Agentic Reinforcement Learning. You will architect the "cognitive" layer of Google's AI stack-developing novel RL recipes, reward modeling systems, and synthetic data flywheels that enable models to reason, plan, and use tools effectively. You will translate frontier research into scalable production infrastructure, solving the "GenAI Engineering Gap" by transforming probabilistic models into reliable, self-improving agentic systems.

Google Cloud accelerates every organization's ability to digitally transform its business and industry. We deliver enterprise-grade solutions that leverage Google's cutting-edge technology, and tools that help developers build more sustainably. Customers in more than 200 countries and territories turn to Google Cloud as their trusted partner to enable growth and solve their most critical business problems.

The US base salary range for this full-time position is $207,000-$300,000 bonus equity benefits. Our salary ranges are determined by role, level, and location. Within the range, individual pay is determined by work location and additional factors, including job-related skills, experience, and relevant education or training. Your recruiter can share more about the specific salary range for your preferred location during the hiring process.

Please note that the compensation details listed in US role postings reflect the base salary only, and do not include bonus, equity, or benefits. Learn more about benefits at Google.

Responsibilities

• Architect and implement advanced Reinforcement Learning (RL) workflows for complex, multi-turn agentic tasks. Develop novel training recipes for reasoning, self-correction, and tool use (e.g., CoT, Tree of Thoughts) to improve model reliability in long-horizon workflows.
• Design robust reward systems and simulation environments ("Digital Twins") to evaluate and train agents.
• Create the "Intelligence Assets" required to train specialized student models, bridging the gap between generalist teacher models and domain-specific production requirements.
• Contribute to the unified middleware layer that democratizes access to SOTA tuning. Implement efficient adaptation techniques (e.g., LoRA, Distillation, Quantization) to ensure high-performance agents can be deployed under strict latency and cost constraints.
• Partner with Google DeepMind researchers to validate novel algorithmic approaches (e.g., outcome-supervised vs. process-supervised RMs) and scale them from 0-to-1 prototypes into 1-to-N production libraries used across Google.
