Our ambition is to become the platform that powers how brands serve, engage and sell through AI. We’re looking for a Research Engineer to help build the intelligence behind Permut’s next generation of AI agents. You’ll work on how agents understand intent, use brand knowledge, select tools and execute actions.

Your work will combine model adaptation, data curation and rigorous evaluation, with a direct path from experiments to production. You’ll help establish the research foundations: which data matters, how we measure progress and how agents improve with experience. Build high-quality datasets from conversations, brand knowledge, agent actions and human feedback.

Design benchmarks that measure factual accuracy, task completion, tool execution and conversation quality. Explore post-training approaches and feedback loops that improve agent performance over time.



Work closely with engineering to deploy successful experiments and measure their impact on quality, latency, cost and reliability.

Show us the models, experiments, projects or open-source contributions you’re proud of, and explain what you learned. 3+ years of experience in AI or machine learning , including implementing, training or improving models. ~ Strong Python skills and experience with frameworks such as PyTorch and the Hugging Face ecosystem. ~ Experience improving data quality: You understand sampling, labeling, coverage and data leakage. ~ You consider latency, cost, reliability and monitoring alongside model quality. ~ You can turn an open question into a research plan and work with engineers to ship the result. Publications are welcome, alongside evidence of strong independent or commercial work. Help define the problem, run the experiments and bring successful work into production.

Real conversations and customer needs shape our research priorities. Reproducible experiments, meaningful evaluations and reliable production behaviour guide our decisions. The opportunity to shape Permut’s research direction and proprietary intelligence.

Real customer problems and a direct path from research to production. Room to grow across model development, data, evaluation and applied AI.
