AI Software Engineer

About the Role Join a small team building AI agents and open-source tools for improving software instrumentation and telemetry. You will develop reliable coding-agent workflows that help engineering teams find and fix instrumentation issues across their codebases. What You'll Do • Build features from specification through production, including GitLab support and workflows that turn telemetry findings into code fixes across repositories. • Improve agent-run reliability with structured outputs, retries, long-running sandbox jobs, and consistent findings across runs. • Develop evaluations to measure how prompt and model changes affect agent quality and cost. • Build the context agents need to review and safely change Go, Java, Kotlin, TypeScript, Python, and .NET code. • Maintain open-source agent skills, keep them current with OpenTelemetry releases, review contributions, and evaluate their impact. • Work with customer engineers and the Customer Success team when delivery requires it. What We're Looking For • At least 5 years of software engineering experience and strong proficiency in TypeScript. • Comfort reading and safely changing code in Go, Java, Kotlin, Python, and .NET. • Experience measuring language model quality with evaluations, golden sets, or production signals. • Experience building with APIs, webhooks, durable workflows, and Postgres. • Ability to communicate through design documents, pull request descriptions, and clear written summaries in an async-first environment. • Open-source maintenance, OpenTelemetry instrumentation, or experience building agent skills, plugins, or MCP servers is valuable. • Experience with GitHub App or GitLab integrations, sandboxed code execution, Cloudflare Workers, or Bun is also useful.
