Staff Software Engineer, Demand Bidder, Ad Serving Platform

📋 Description

• Design, build, and operate core components of a large-scale, real-time distributed decisioning system with strict latency requirements
• Take end-to-end ownership of specific subsystems: architecture, implementation, testing, deployment, on-call, and long-term evolution
• Build a working mental model of a highly distributed, complex production system, and make high-leverage contributions
• Identify opportunities to continuously evolve the system and tooling
• Partner with engineers and applied scientists working at the intersection of distributed systems and statistical/ML-driven decision-making
• Diagnose and resolve subtle, often timing- or statistics-related issues in a highly concurrent, multi-region distributed system

🎯 Requirements

• 10+ years of experience designing, building, and operating large-scale, low-latency distributed systems — ideally including at least one system you built substantially from the ground up
• A demonstrated track record of owning complex systems end-to-end: design, build, operate, on-call, and iterate based on production feedback
• Proven ability to ramp quickly into unfamiliar, complex, large codebases and become productive fast; you enjoy the figure it out part of the job as much as the build it part
• Experience evolving and refactoring live, business-critical systems without compromising uptime or correctness
• Strong command of Java, with a solid foundation in algorithms, data structures, concurrency/multi-threading, and performance optimization
• Practical experience with distributed caching, high-throughput messaging/streaming systems, and SQL/NoSQL datastores

🎁 Benefits

• Global mental health and financial wellness resources
• Healthcare options including medical, dental, and vision coverage
• Life, disability, and commuter benefits, plus retirement options (401(k)/pension)
• Generous paid time off and leave policies
• Accommodations available for applicants requiring adjustments
