Description
Most AI systems work in demos. Very few hold up in real customer environments.
This team is building the decision-making systems behind AI agents that operate across voice, chat, and email — where performance is measured in outcomes, not benchmarks.
You’ll work on models that need to reason over time, handle multi-step workflows, and stay consistent across entire interactions. Not just once, but repeatedly, under real-world constraints.
This is applied research that ships. You’ll take ideas from early concept through to production, owning how systems behave when deployed at scale.
The challenge is not just capability. It’s reliability — making reasoning systems that can operate across long-context interactions, manage memory, use tools, and execute workflows without breaking down.
You’ll be working closely with product and engineering teams, iterating on real-world failures, and improving systems based on how they actually perform in production.
What you’ll work on
- Designing and improving reasoning systems for real-world agent workflows
- Building and refining memory, retrieval, and multi-step execution systems
- Developing post-training and evaluation approaches for deployed models
- Iterating on systems based on real user behaviour and performance
- Taking research ideas through to production environments
What they’re looking for
- Experience working on LLM systems in production
- Background in RL, post-training, or agent-based systems
- Experience building systems involving memory, reasoning, or tool use
- Strong engineering fundamentals and ability to ship end-to-end systems
- Clear understanding of how models behave outside of controlled environments
Why this role
- Work on systems judged by real users, not offline metrics
- Direct ownership of how models behave in production
- High autonomy in a fast-moving, product-driven team
- Real-world complexity, not sandboxed problems
