Staff/Senior AI Engineer, AI for Code

Responsibilities

• 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.
