You work closely with Product Management and architects on new application design and major enhancements, and you serve as the first technical escalation point when something hard needs to be sorted out in your area. The decisions you make end up in production code that matters.Strong software engineering fundamentals and the technical depth to independently own complex areas of a product are the primary requirements. Domain knowledge is valuable but not required at hire.Positions are available across a range of teams.

• Experience designing and owning the architecture of a complex software system or major subsystem, with technical decisions that held up across multiple releases
• A track record of providing technical leadership across a team or product area

• Serve as the technical authority for your area of the application or architecture: the person the team turns to when a decision is hard or a problem is deep
• Evaluate architecture and implementation for performance, scalability, and security weaknesses, and drive improvements through to resolution
• Lead design and code reviews with a focus on long-term quality, not just correctness
• Challenge the delivery process when it produces slow feedback, unnecessary risk, or poor outcomes
• Mentor engineers at junior and mid levels through code reviews, technical guidance, and the standard you set in your own work
• Stay current on tools, practices, and technologies relevant to your area, and drive adoption where they improve the product
