Job Summary
Seeking a Lead Software Engineer (ENG 5) to serve as a principal-level individual contributor driving the technical direction of our Buyer Cloud Ad Serving platform.

The Ad Serving system is the high-throughput backbone of the demand-side platform (DSP). It processes billions of ad auctions daily, executes complex real-time decisioning strategies, and delivers responses in single-digit milliseconds.

In this role, you will lead the architecture of mission-critical distributed systems, tackle complex performance and scale challenges, and influence engineering practices across multiple teams all without direct people management responsibilities
 
Job Description
Responsibilities: 
  • Architectural Leadership: Lead the end-to-end architecture, design, and execution of highly scalable, low-latency backend services for the Buyer Cloud platform.

  • System Optimization: Identify and eliminate performance bottlenecks in distributed workflows operating under strict latency budgets. 
  • Cross-Functional Partnership: Partner with Product, Infrastructure, SRE, and Data Engineering to define technical roadmaps and align technical strategy with business goals. 
  • Engineering Standards: Establish best practices for design reviews, code quality, testing, observability, and incident root-cause analysis (RCA). 
  • Mentorship & Talent Growth: Mentor senior and mid-level engineers through design coaching, code reviews, and architectural guidance. 
  • Consistent exercise of independent judgment and discretion in matters of significance.
  • Regular, consistent and punctual attendance. Must be able to work nights and weekends, variable schedule(s) as necessary.

  • Core Languages: Expert-level proficiency in compiled/high-performance languages (C++, Go, Java, or Rust). 
  • Distributed Systems: Proven track record of designing, operating, and troubleshooting large-scale distributed backend systems in production. 
  • Systems Engineering: Deep understanding of concurrency, multithreading, memory management, networking protocols, and performance profiling on Linux. 
  • Cloud & Infrastructure: Experience building containerized, cloud-native services (AWS, Kubernetes, ECS, or equivalent) with robust observability (metrics, tracing, logging). 
 
Bonus Points:
  • Experience with ultra-low-latency, real-time decisioning systems (e.g., AdTech/DSPs, financial trading, real-time analytics, high-frequency auction systems). 
  • Experience handling petabyte-scale datasets or systems processing millions of requests per second (RPS). 
  • Familiarity with distributed datastores and storage platforms (e.g., Aerospike, Snowflake, event streaming architectures). 
  • Demonstrated experience modernizing legacy architectures and driving cloud-native adoption.
