Responsibilities
- Design, build, and operate core components of a large-scale, real-time distributed decisioning system with strict latency requirements.
- Own specific subsystems end to end across architecture, implementation, testing, deployment, on-call, and long-term evolution.
- Develop a working model of a complex production system and make high-leverage contributions to its architecture and tooling.
- Diagnose and resolve timing- and statistics-related issues in highly concurrent, multi-region distributed systems.
- Partner with engineers and applied scientists on distributed systems and statistical or ML-driven decision-making.
- Mentor engineers and raise standards for engineering rigor, testing discipline, and operational excellence.
- Drive alignment across engineering, product, business, and technical and non-technical stakeholders.
Requirements
- At least 10 years of experience designing, building, and operating large-scale, low-latency distributed systems, ideally including a system built substantially from the ground up.
- Demonstrated end-to-end ownership of complex systems, including design, implementation, operations, on-call, and iteration based on production feedback.
- Strong command of Java and solid foundations in algorithms, data structures, concurrency, multithreading, and performance optimization.
- Practical experience with distributed caching, high-throughput messaging or streaming systems, and SQL or NoSQL datastores.
- Experience operating cloud infrastructure at scale using GCP or AWS.
- A B.S. or M.S. in Computer Science or Engineering, or equivalent practical experience.
- Experience with statistical, control-theory, or ML-driven techniques in production decision-making systems is preferred.
- Real-time bidding or ad-tech experience is preferred, as is experience in adjacent low-latency domains such as trading, ranking or recommendation, matchmaking, risk, or fraud systems.
- Experience using AI coding assistants such as Claude Code or Cursor in production work is expected, along with sound judgment in reviewing AI-assisted output.
Benefits
- Health insurance, equity awards, life insurance, disability benefits, parental leave, wellness benefits, and paid time off are available.
- Benefits may include medical, dental, vision, accident, commuter, retirement options, mental health support, and financial wellness resources, depending on location and role.
