Principal Member of Technical Staff

As a Principal Member of Technical Staff, you will lead the design and development of major new features within existing systems. You will serve as a key driver in improving engineering practices, operational processes, development workflows, and team ownership, while also mentoring others. Collaboration across teams may be required on occasion.
You consistently write correct, secure, maintainable, and robust code, along with comprehensive tests. You are responsible for driving the design and operational readiness of your features and subsystems, ensuring they meet high standards of reliability and performance. You contribute to planning efforts, proactively identify and mitigate risks, and influence the design of features and subsystems across the organization.
You operate independently on most projects, occasionally seeking guidance in areas requiring deep industry experience with mission-critical systems—such as cross-team coordination, nuanced architectural trade-offs, and designing for scalability, security, availability, concurrency, performance, and operational robustness.
You frequently identify and resolve issues without external input, lead root cause analyses, and propose effective solutions. You develop new metrics and dashboards to enhance situational awareness, and implement solutions that reduce operational overhead, improve availability, enhance compliance with organizational standards, and systematically reduce technical debt.
