You will contribute through hands-on implementation, clear design communication, and strong collaboration. You’ll write and review design docs for your work, define success metrics (e.g., latency, error rate, throughput, routing quality, and cost efficiency), and improve performance and reliability through testing, safe deployments, and monitoring. You will participate in on-call and first responder rotations, resolving issues within SLOs and escalating when needed, and help continuously improve the resilience and maintainability of the services you touch. At GitHub, we value developer empathy, transparency, and inclusive collaboration, and we work iteratively with a bias toward action and impact.
Responsibilities
Design, develop, test, and ship high-quality technical solutions that scale across multiple GitHub services.
Build and evolve LLM routing/orchestration capabilities (e.g., model/endpoint selection, fallback, retries, guardrails, and request shaping) to optimise user experience, quality, latency, and cost.
Design and implement APIs and service components that support Copilot integrations and intelligent inference pathways.
Collaborate cross-functionally with engineering, product, and applied AI partners to define and deliver innovative solutions.
Own and advocate for system health and quality, including participation in on-call and first responder rotations.
Write architecture briefs and proposals, run experiments/prototypes, and use production signals to drive iterative improvements.
Define and track success metrics, including platform reliability metrics (SLOs) and routing effectiveness metrics.
Use CI/CD and safe deployment practices to deliver changes confidently and quickly.
Mentor peers through technical leadership, pairing, and thoughtful code/design reviews.
Become intimately familiar with the systems you build and take pride in writing maintainable code.
