Principal Software Engineer, Copilot Code Review

Job description

Accountabilities: Lead the technical strategy, architecture, design, implementation, and evolution of AI-powered code review systems, remaining deeply hands-on with the most complex engineering challenges. Define how the review agent reasons, including the context it uses, models it runs, and information it carries across reviews. Evaluate emerging model capabilities and collaborate with research and model-development teams to translate advances in AI into stronger code review experiences. Establish and continuously improve the definition of high-quality AI code review through offline evaluations, online experiments, production data, and measurable outcomes. Own the end-to-end review experience across development environments, applications, command-line workflows, and pull requests. Ensure the reliability, scalability, and operational excellence of a high-throughput distributed service, including participation in an on-call rotation. Make complex technical and architectural trade-offs while balancing immediate delivery needs with long-term product and engineering quality. Mentor senior and staff engineers, influence technical direction across teams, and contribute to the evolution of engineering practices and workflows. Explore new approaches to agentic software development and help evolve engineering workflows to make teams more effective and productive. Requirements: 11+ years of professional experience in software engineering, computer science, or a related technical discipline, with substantial experience delivering and operating production software. Equivalent experience may be considered through combinations of education and professional background, including relevant associate, bachelor’s, master’s, or doctoral degrees. Strong technical leadership experience, including ownership of architecture, complex technical decisions, and large-scale production systems. Extensive programming experience in one or more languages such as C, C++, C#, Java, JavaScript, Go, Ruby, Rust, or Python. Proven experience designing and operating scalable distributed systems, including web services, APIs, cloud infrastructure, and modern software engineering practices. Hands-on experience applying frontier AI/LLM models at scale, with a practical understanding of their capabilities, limitations, and production considerations. Experience building or operating LLM-powered or agentic products in production, or working closely with research teams to bring advanced model capabilities into real-world products. Experience designing evaluation frameworks that determine whether model-driven products are improving, including the ability to identify weaknesses in existing evaluation methodologies. Strong depth in Go, Ruby, TypeScript, or Python is highly valuable, particularly alongside experience operating distributed services in production. Ability to navigate ambiguity, simplify complex technical problems, make sound trade-offs, and deliver high-quality solutions in a fast-paced environment. Strong communication, collaboration, mentoring, and influencing skills, with the ability to work effectively across technical and non-technical disciplines. Benefits: Annual base salary range of $160,200–$425,000 USD, depending on factors such as location, experience, knowledge, skills, and qualifications. Eligibility for an annual bonus and stock-based rewards for applicable roles. Potential additional incentive opportunities depending on role and compensation plan. Remote-first working environment within the United States. Competitive benefits designed to support employees’ health, wellbeing, and professional development. Generous learning and growth opportunities. Inclusive, collaborative culture focused on customer impact, continuous improvement, ownership, and innovation. Opportunity to work on cutting-edge AI and agentic software development technologies at significant scale.
