Staff Software Engineer, Demand Bidder, Ad Serving Platform

Overview

Staff Software Engineer (Staff scope) for Roku’s Ad Serving Demand Bidder team, building and operating core components of a large-scale real-time ad decisioning platform with strict latency requirements.

What you'll do

• Design, build, and operate core components of a real-time distributed decisioning system.
• Take end-to-end ownership of subsystems including architecture, implementation, testing, deployment, on-call, and long-term evolution.
• Build a mental model of a highly distributed production system and make high-leverage contributions.
• Continuously evolve the system and tooling.
• Partner with engineers and applied scientists on distributed systems and statistical/ML-driven decision-making.
• Diagnose and resolve subtle timing- or statistics-related issues in a concurrent multi-region system.
• Mentor engineers and raise the bar on engineering rigor, testing discipline, and operational excellence.
• Communicate with technical and non-technical stakeholders to drive alignment across engineering, product, and business partners.

What you'll need

• 10+ years of experience designing, building, and operating large-scale, low-latency distributed systems, ideally including building a system substantially from the ground up.
• Track record of owning complex systems end-to-end (design, build, operate, on-call, and iterate based on production feedback).
• Ability to ramp quickly into unfamiliar, complex, large codebases and become productive fast.
• Experience evolving/refactoring live, business-critical systems without compromising uptime or correctness.
• Strong command of Java plus a foundation in algorithms, data structures, concurrency/multi-threading, and performance optimization.
• Practical experience with distributed caching, high-throughput messaging/streaming, and SQL/NoSQL datastores.
• Comfort operating in cloud infrastructure (GCP or AWS) at scale.

Details

• Hybrid work: teams generally work in the office Monday through Thursday; Fridays are generally flexible for remote work.
• Company teams may require five days' a week attendance for roles or assigned office locations.
