Seeking a Lead Principal Platform Software Engineer to drive critical cross-group platform initiatives. This role involves enhancing reliability, performance, and compliance across systems. You will tackle complex distributed-systems challenges, establish compatibility and deprecation strategies to minimize risks, and implement shared observability frameworks and capacity models. Collaboration with SRE and security teams is key to defining architectural guardrails and security controls.

This position offers the opportunity to shape foundational code for new projects and prototypes. You will be instrumental in improving all phases of the software development lifecycle and mentoring engineers across teams. Acting as a subject matter expert, you'll guide new feature development, ensure software design documentation is clear, and lead reviews to enhance processes, architecture, and code quality. Debugging and troubleshooting highly complex software issues using modern technologies will be a core part of the role.

Key responsibilities include setting group-wide guardrails for platform interoperability, security, and client library governance. You will own cross-group programs such as identity, configuration, and API gateway standards, driving measurable improvements in reliability and performance. Establishing and rolling out shared observability frameworks adopted by multiple teams, while managing deprecation risks, is crucial.

Additionally, you will lead initiatives for software system structural design, defining project scope and influencing design recommendations. Providing technical guidance and domain expertise in software architecture decisions will drive key organizational choices. You will also collaborate with stakeholders to align software architecture with business and customer goals, implementing innovative strategies for performance optimization and scalability. Addressing customer issues, investigating root causes, and providing expert technical support to mitigate recurrence are vital aspects of this role.

Ideal candidates will possess a deep understanding of software development, coding, design, testing, and optimization. Expertise in software architecture and system design is essential. You should be proficient in collaborating on issues and defects related to software products, and in maintaining compliance with security and practices standards. A strong background in development operations and system maintenance is also required.

Core responsibilities extend to strategic planning and execution, managing timelines and deliverables for high-impact projects. Influencing cross-functional leaders and fostering partnerships across teams and with external stakeholders are key. You will lead advanced problem-solving efforts, acting as an escalation point for complex issues and driving data-driven solutions. A commitment to continuous learning and improvement, staying abreast of industry trends and technologies, is paramount. You will also contribute to talent development and organizational talent strategy.
