## About the Role

Do you have experience in Communication skills?, Do you have a Master's degree?, * Strong software engineering fundamentals and a track record of shipping complex systems to production.

 * Hands-on experience building LLM-powered products, coding agents, or other AI systems.
 * Experience improving model behavior through systematic iteration, whether via prompting, context engineering, fine-tuning, preference optimization, or broader post-training methods.
 * Practical experience with evaluation and benchmarking for LLM systems, including defining task-grounded success metrics and catching regressions.
 * Experience working from noisy real-world signals rather than only from clean benchmark datasets.
 * Good judgment about trade-offs between model quality, latency, reliability, privacy, and cost.
 * Confidence working with ambiguity and taking ownership of a direction over multiple iterations.
 * Strong communication skills and the ability to align engineering and product decisions.

## Description

* Build production-ready coding agents and agentic workflows for real developer tasks inside JetBrains products.
 * Turn promising model capabilities into dependable product behavior through prompt design, context construction, fine-tuning, instruction-tuning, or other post-training techniques where appropriate.
 * Design and improve the agent loop itself, including tool use, execution strategy, safeguards, and task completion quality.
 * Create evaluation suites and quality infrastructure for agent behavior, including online and offline evaluations, regression checks, failure analysis, and release criteria.
 * Build feedback loops from real usage, using logs, user signals, and edge cases to improve data, evaluations, and agent behavior.
 * Work with both hosted frontier APIs and self-hosted or open-weight models, making pragmatic decisions about where each model belongs based on capability, latency, reliability, privacy, and cost.
 * Collaborate closely with product managers, software engineers, ML engineers, and researchers to ship features end to end.
 * Help define the technical direction for future work, especially in ambiguous areas where we need strong judgment rather than a prewritten playbook., * You ship one or more agent capabilities that users can rely on for meaningful work, not just demos.
 * You establish better evaluation coverage and clearer release criteria for agent behavior.
 * You help the team build a repeatable loop from idea to shipped capability: prototype, evaluate, learn from usage, improve, and scale.
