Lead the design, implementation, operation and scaling of GitHub's Blackbird code search engine powering lexical and semantic search for GitHub and Copilot products. Work on distributed, high-scale systems, integrate AI/ML features and AI agents, participate in on-call incident response, and provide technical leadership and mentorship. Requires substantial software engineering experience and proficiency in languages such as Rust, Go, Java, Python, and others.

Join GitHub's Copilot Agents organization to design, implement, and operate systems that enable AI agents to acquire, retain, and apply software-development context (agent memory, context retrieval, search, knowledge graphs). Role involves end-to-end platform and API development, defining technical direction, establishing evaluation and telemetry, ensuring privacy/security, participating in on-call rotations, and mentoring engineers. Requires substantial production software engineering experience and familiarity with languages such as Rust, Go, Python, TypeScript, or similar.

Hands-on senior engineering role building GitHub Copilot Code Review: define and implement how the review agent reasons and which models run, own reliability and on-call for a high-throughput service, design offline and online evaluations, collaborate with research and model teams, and mentor senior staff. Requires extensive software engineering experience and working with models at scale.

GitHub is hiring a Senior Data Scientist to lead data acquisition and quality, develop and validate ML models, mentor peers, and communicate findings to technical and non-technical stakeholders. The role requires experience with statistical and ML techniques, programming (Python/R), query languages (SQL/KQL), data tools (Spark, Airflow), and delivering productionized models and visualizations.

Work remotely (United States) on GitHub's Copilot Code Review team to own end-to-end features: improve agent review behavior and context, integrate frontier models, balance review quality with latency/cost, prove changes with offline and online evals, and keep a high-throughput service healthy (including on-call rotation). Experience with production software, distributed systems, LLM/agentic products, and languages such as Go, Ruby, TypeScript, or Python is emphasized.

Remote Staff Research Engineer role on GitHub Next focused on turning ambitious AI and software development ideas into working prototypes and products. Requires deep software development and research experience (minimum 8 years options described), prototyping skills, familiarity with ML/AI, frontend/backend stacks, and collaboration across teams and stakeholders.
