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 Senior Staff Engineer, you will be a technical leader shaping the architecture and capabilities of our next-generation ads platform, with a focus on highly scalable, low-latency distributed systems and data pipelines. You will partner closely with senior technical and product leaders across e Bay and will be a key driver of technical strategy, design excellence, and engineering best practices for the team.

What you will accomplish:

• Define and drive the architecture for large-scale, low-latency, fault-tolerant distributed systems that power ads experiences for millions of e Bay customers worldwide.

• Deliver high-quality services and data pipelines end to end—leading design, implementation, and rollout—to improve performance, resilience, and customer experience across our Ads platform.

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

• Produce clear, well-structured technical design documents and lead design and code reviews that raise the quality bar for the broader engineering organization.

• Influence and inspire a community of developers, analysts, and product managers by clearly communicating technical decisions, trade-offs, and results, and by championing capability-oriented architecture and engineering best practices.

• Provide technical leadership, coaching, and mentorship to help team members grow their skills, increase their impact, and contribute to a high-performing, inclusive engineering culture.

What you will bring:

• Bachelor’s degree in Computer Science or related field with 10+ years of relevant experience, or Master’s degree with 8+ years of experience, or equivalent practical experience.

• Deep expertise in software design and development, including system architecture, distributed systems, data structures, algorithms, object-oriented and functional programming.

• Strong hands-on experience building services and APIs using languages such as Java or Scala and RESTful web services.

• Proven experience delivering data-driven applications using both relational databases (RDBMS) and NoSQL technologies, with a strong focus on scalability and reliability.

• Experience designing and operating large-scale, fault-tolerant systems using big data and streaming technologies such as Spark, Flink, and Kafka.

• A self-directed, delivery-focused approach, with the ability to thrive in a fast-paced, dynamic environment and collaborate effectively with cross-functional partners across time zones.
