Senior Software Engineer | Kimchi (Harness Team)

Описание

As a Senior Software Engineer, you will work on key features of the product, minimizing process friction to ship high-agency features across multiple parts of the tech stack.

Responsibilities

• Architect planner/executor/evaluator pipelines – planning with a reasoning model, execution with a fast one, evaluation with a third. No self-verification.
• Manage agent memory and context – state persistence across sessions, context compaction, tool-call offloading.
• Own the harness surface – TUI, MCP integrations, telemetry.
• Work directly with users, including our own colleagues, to identify, understand and fix pain points.

Requirements

• Production experience with Go or TypeScript is strongly preferred; candidates without either should demonstrate strong systems programming skills in a comparable language.
• Strong debugging, optimization, and performance-tuning skills – including query profiling, index design, and database performance tuning beyond ORM usage.
• Strong English skills, both verbal and written.
• You've personally driven a complex project end-to-end.

Nice to have

• Hands-on experience with cloud platforms (AWS, GCP, or Azure) and Kubernetes is a strong plus.

• Flexible, remote-first global environment.
• Collaborate with a global team of cloud experts and innovators, passionate about pushing the boundaries of Kubernetes technology.
