About the jobWe are looking for a Staff Software Engineer to help our efforts in Recursive Self-Improvement (RSI), Automated Prompt Optimization (APO), and Agentic prompt simplification. We are working towards ensuring that multimodal journeys in Search are fully onboarded onto RSI, and we also motivate horizontal improvements across Search from our learnings.
In this role, you will help set and execute the technical direction as part of a strong team for autonomous, closed-loop agentic systems that continuously optimize, compress, and modularize system instructions and agent trajectories-improving instruction-following fidelity, reasoning quality, and inference efficiency at scale.
In Google Search, we're reimagining what it means to search for information - any way and anywhere. To do that, we need to solve complex engineering challenges and expand our infrastructure, while maintaining a universally accessible and useful experience that people around the world rely on. In joining the Search team, you'll have an opportunity to make an impact on billions of people globally.
Individual pay is determined by factors including job-related skills, experience, and relevant education or training.

Responsibilities - Partner with senior leads to architect closed-loop RSI pipelines that autonomously diagnose failure modes, refine instructions/trajectories, synthesize targeted training/eval data, and verify gains without manual intervention.
- Investigate and build automated multi-agent systems that audit, compress, and de-conflict complex model context-maximizing token efficiency and inference speed while preserving behavioral and safety guardrails.
- Bridge inference-time context engineering with model post-training (SFT/RL) to distill complex rules into model weights.
- Advance automated optimization methods for production multimodal and reasoning systems.
- Help define the multi-quarter roadmap across Engineering and Research teams, establishing rigorous automated evaluation gates.
