Overview

GitHub is shaping the future of software development in the age of AI agents — and search is at the heart of it. As GitHub's lexical and semantic code search engine, Blackbird powers context retrieval for business-critical experiences across the platform and our Copilot products, including Cloud Agent, Code Review, Copilot CLI, and VS Code.

We're looking for a Senior Software Engineer to help develop, scale, operate and extend Blackbird. This role is specifically focused on infrastructure, operations, automation, CI/CD, DX, observability, and security. You'll be part of our Copilot Agents organization, positively impacting millions of software developers and AI agents around the world who are building everything from open source to global enterprises.

We are looking for creative problem solvers and diverse thinkers, people who care about culture as well as customers and features. We believe that how we do things is as important as what we do. Big vision, a common purpose, passion for quality, curiosity, dedication, and investment in fun and collaboration are what lead to great results. Great products reflect the teams that build them.

More of the world’s development data lives on GitHub than anywhere else. Helping developers navigate and understand that data is a core part of GitHub’s mission, and an area with significant potential we have only begun to realize. We have high aspirations for how we can help developers understand and navigate code, and for making collaboration more seamless. The foundation for these efforts is our purpose-built code search engine which powers lexical and semantic code search in GitHub’s core search experience as well as GitHub’s Copilot products.

The ideal candidate has strong experience with distributed systems, cloud infrastructure, DevOps, reliability engineering, as well as the ability to work autonomously, learn quickly, and communicate and set technical direction. You will be working within a strong team of staff and principal engineers as well as collaborate with partner teams across the Copilot Agents organization.

As a software engineer at GitHub, you will enhance the collaboration experience at GitHub by working closely with a community of engineers and designers with a distributed, diverse and passionate team delivering the services that millions of developers depend on. In this role you will design, prototype, implement, ship and support highly performant and globally scalable code search technology with your team.

Responsibilities

• Own and advocate for the health and quality of the systems that the team builds, including participating in on-call and first responder rotations.
• Drives efforts to collect, classify, and analyze data on a range of metrics (e.g., health of the system, where bugs might be occurring).
• Drives the refinement of products through data analytics, and makes informed decisions in engineering products through data integration.
• Considers and drives comprehensive application of automation within production and deployment of a product.
• Runs code in simulated or other non-production environments to confirm functionality and error-free runtime for products.
• Improves development quality, development velocity, and team performance through modeling contributions to improvement of developer tooling.
• Drives efforts to ensure the correct processes are followed to achieve a high degree of security, privacy, safety, and accessibility.
• Creates and ensures the presence of visible evidence (e.g., audit logs, system reports, security compliance) to demonstrate compliance for products.
• Leverages subject-matter expertise of product features, incorporates service health indicators (e.g., SLOs) to prioritize work focused on, and partners with appropriate stakeholders (e.g., project managers) to drive collaboration on the workgroup's project plans, release plans, and work items.
• Write architecture briefs and proposals, carry out code experiments, and build prototypes to learn how we can achieve planetary scale with our systems.
• Design and implement APIs to facilitate seamless integration between software components.
• Utilize CI/CD tools to set up automated pipelines for continuous integration and delivery.
• Become intimately familiar with the systems you build and take pride in writing maintainable code.
• Design, develop, test and ship high-quality technical solutions that scale across multiple GitHub services.
