About The Position
We are looking for a Software Engineer or Senior Software Engineer (Backend) to join our core engineering team in San Francisco. You will work on the systems that sit at the heart of our programmatic Demand-Side Platform (DSP) — the real-time bidding engine that processes millions of bid requests per second with sub-100ms latency requirements. This is infrastructure that directly moves revenue. You will work alongside data scientists, infrastructure engineers, and product stakeholders to build and evolve the systems that power real-time bidding, machine learning inference, and ad delivery at scale.
Requirements
- 3+ years of backend development experience, ideally in low-latency or distributed environments
- Proficiency in Rust, C++, Go, or Java with hands-on production experience
- Strong knowledge of multithreading, concurrency, memory management, and network I/O
- Experience with distributed systems: message queues, sharding, replication, and failover strategies
- Comfort with profiling tools, performance benchmarking, and distributed tracing
- Familiarity with CI/CD pipelines and containerized deployment (Docker/Kubernetes a plus)
- Bachelor's or Master's degree in Computer Science, Engineering, or a related field
Nice To Haves
- Familiarity with real-time bidding, ad tech, or financial trading systems is a strong plus
Responsibilities
- Design, develop, and maintain high-performance backend services for our real-time ad bidding platform
- Build and optimize distributed systems capable of handling millions of queries per second with sub-100ms latency
- Work closely with data scientists to integrate and deploy machine learning models into production environments
- Improve system scalability, observability, and fault tolerance through clean architecture and metrics-driven design
- Collaborate with cross-functional teams to align technical execution with product goals
- Participate in peer code reviews, technical design reviews, and performance debugging sessions
- Write clean, maintainable, well-tested code and contribute to raising the bar on engineering quality
- Mentor junior engineers and help shape team practices as we scale
Benefits
- Work at the core of a revenue-critical system
- True low-latency systems engineering at scale
- Small, senior team with real autonomy
- At the intersection of ML and infrastructure
- A platform in active transformation
