PubMatic is seeking to lead the design and development of their next-generation mobile app monetization platform, focusing on building high-performance, scalable, real-time systems for programmatic monetization across various mobile ad formats.
Requirements
- 8+ years of backend engineering experience, with a proven track record of building high-scale, low-latency systems, preferably in the mobile app advertising or programmatic AdTech domain.
- Strong programming expertise in C++, with additional experience in Go or Java.
- Solid understanding of Linux/UNIX environments and system-level programming (multi-threading, multi-processing, memory management).
- Proficient in data structures, algorithms, and core computer science principles, with experience designing modular, scalable, and fault-tolerant systems.
- Deep understanding of programmatic advertising workflows, including RTB, OpenRTB 2.x/2.6, bid lifecycle, and mobile SDK monetization.
- Experience integrating with DSPs, ad exchanges, mediation platforms, and working with SDK-DSP-SSP pipelines, including device graph utilization and session-aware ad serving.
- Hands-on experience with real-time ML inference pipelines, working closely with ML engineers and integrating model predictions into latency-sensitive systems.
Responsibilities
- Architect and implement scalable APIs and backend services powering mobile app monetization, including SDK-driven request handling, real-time targeting, ML-based decisioning, and campaign selection logic.
- Develop low-latency, high-throughput server-side systems capable of handling billions of RTB bid requests daily.
- Collaborate with ML Engineering and Data Science teams to integrate models for yield optimization and performance enhancement.
- Design and support A/B testing and experimentation frameworks to evaluate monetization strategies across diverse ad traffic.
- Contribute to the long-term technical strategy and roadmap for the mobile monetization platform.
- Champion engineering best practices in observability, fault tolerance, API performance, and modular architecture.
Other
- Excellent interpersonal, written, and verbal communication skills with a collaborative mindset and strong ownership over deliverables.
- Hybrid work schedule (3 days “in office” and 2 days “working remotely”)
