The Role
We're hiring a Staff Software Engineer (Backend) to lead the technical direction of the systems powering our next-generation, pixel-less ad targeting platform.

This role is accountable for driving the technical strategy behind ContextGPT integrations, enabling scalable growth through new partners, supply sources, and platform capabilities. You'll work across multiple engineering teams, influence architectural decisions, and partner closely with Product, Infrastructure, and external stakeholders to deliver durable solutions that accelerate business growth.
This position will be located in Bellevue with a hybrid work schedule of 3 days in office (Mon/Tue/Wed) and 2 days remote optional (Thursday/Friday).

- Mentor senior engineers through design reviews, technical guidance, and architectural leadership
- Improve developer productivity by driving platform improvements, reusable components, and engineering standards
- Serve as a technical leader during production incidents, driving root cause analysis and long-term preventative improvements
Who you are:
- Ownership, Drive & Agency: You identify systemic problems, create solutions without waiting for direction, and drive cross-functional execution through influence rather than authority.

- Architectural thinker: Comfortable making long-term architectural decisions that balance scalability, performance, maintainability, and business objectives across multiple systems.
- Cross-functional collaborator: Able to partner effectively with Product, Infrastructure, Engineering leaders, and external partners while aligning multiple stakeholders around technical direction.
- Mentor & multiplier: Passionate about growing engineers through coaching, design reviews, and establishing engineering best practices that elevate the entire organization.
- Operational excellence: Strong focus on reliability, observability, testing, automation, and long-term system health.
- Resilient & adaptable: Comfortable leading through ambiguity, balancing competing priorities, and making thoughtful technical tradeoffs.
- In-person collaborator: Excited to work onsite MTW in Bellevue, WA.
