About the team and the role:

The e Bay Ads team builds the advertising and promotion experiences that power growth for sellers and delight buyers on one of the world’s most trafficked and loved commerce platforms. We are a highly collaborative group of engineers, data scientists/applied researchers, product managers, designers, and analysts who experiment, learn, and ship at scale.

As a Staff Engineer, you will be a hands-on technical leader shaping the next generation of our ads platform, with a focus on large-scale applications, low-latency APIs, and robust data pipelines. You will partner closely with cross-functional teams to design and deliver capability-oriented architectures, guide the software development lifecycle end to end, and help grow an inclusive, high-performing engineering culture.

What you will accomplish:

• Define, design, and implement highly scalable, resilient, and performant distributed systems and low-latency APIs that improve customer experience across e Bay’s Ads platform.

• Deliver high-quality services and data-driven applications end to end—leading design, implementation, testing, and rollout—while rigorously following Definition of Done (DoD) and release criteria for reliability and quality.

• Partner with architects, product managers, engineers, data scientists/applied researchers, analysts, and operations teams to build innovative, data-informed solutions aligned with e Bay’s business goals and technical principles.

• Lead product and system design efforts, producing clear, well-structured technical design documents and driving design and code reviews that raise engineering standards for the team.

• Provide day-to-day technical leadership, coaching, and mentorship to engineers—supporting hiring efforts, onboarding, and growth of junior team members—while leading by example and sharing knowledge broadly.

• Serve as a strong agile leader for your scrum team, effectively running scrum ceremonies, aligning on priorities, and driving work to successful completion in a fast-paced, dynamic environment.

What you will bring:

• Bachelor’s degree in Computer Science or related field with 8+ years of relevant experience, or Master’s degree with 6+ years of experience, or equivalent practical experience in software engineering.

• Strong foundation in computer science, including system architecture, distributed systems, data structures, algorithms, object-oriented analysis and design, and functional programming.

• Hands-on experience building services and APIs using Java and/or Scala and RESTful web services, with a track record of delivering production systems at scale.

• Experience building data-driven applications using both relational databases (RDBMS) and NoSQL technologies, with an emphasis on scalability, reliability, and performance.

• Proven experience designing and operating highly scalable, fault-tolerant distributed systems and services for large web sites, leveraging big data and streaming technologies such as Spark, Flink, and Kafka.

• A self-driven, ownership-oriented mindset, with a delivery-focused approach and the ability to thrive in a collaborative, fast-paced environment—planning, implementing, and driving product work to successful completion with cross-functional partners.
