MTS 1, Software Engineer, Data Platforms

Software Engineer

Cloud Data Technologies (CDT) team at eBay is responsible for all the data infrastructure and management of end-to-end data lifecycle for all eBay data from onsite to analytics use cases. We are seeking a Software Engineer passionate about data-driven technologies and architectures.

About the Role

We're seeking a Member of Technical Staff 1 (Software Engineer) who can work independently and is an expert in distributed systems. You'll design and deliver well-scoped services and features that advance eBay's Core Data Platform—improving scalability, reliability, and developer experience. This role is Data Platform Engineering (not data engineering): you'll build and evolve the platform itself rather than author application pipelines.

What You'll Do and Learn

• Independently design, implement, and ship distributed services and features end-to-end (design → code → tests → deploy → operate).
• Build core platform capabilities across ingestion, streaming, lakehouse/warehouse, catalog, and governance.
• Write production-grade code with strong observability (metrics, logs, traces) and SLOs, and participate in on-call for the services you own.
• Diagnose and resolve performance, scalability, and correctness issues in distributed environments.
• Contribute design docs for your areas; participate in reviews to uphold reliability, security, and cost best practices.
• Collaborate with product, infra, and analytics teams to align technical work with business outcomes.

What You Bring

• 6+ years of professional software engineering experience (or equivalent impact).
• Expertise in distributed systems fundamentals (consensus, replication, partitioning, consistency models, fault tolerance) and practical experience building and running such systems in production.
• Strong coding skills in Java/Python and familiarity with CI/CD.
• Hands-on with some of: Kafka/Flink, Spark, Delta/Iceberg, Kubernetes, NoSQL/columnar stores.
• Proven ability to work independently, make sound tradeoffs, and deliver quality outcomes with minimal supervision.
• Solid debugging, performance analysis, and system design skills.

Nice-to-Haves

• Experience building multi-tenant platform services, data governance, or privacy-by-design controls.
• Contributions to open-source distributed systems or data platforms.

What Success Looks Like (6–12 Months)

• Consistently ships independent, well-scoped features/services to production with strong reliability.
• Demonstrably improves throughput/latency/cost or availability/SLOs on owned services.
• Becomes a go-to engineer for distributed-systems debugging and design conversations within the team.
• Maintains high code quality, test coverage, and quality-in-release metrics.

Why Join CDT @ eBay

• Impact at scale: Your platform work powers analytics and ML across a global marketplace.
• Hard problems: Streaming freshness/correctness, storage/compute efficiency, multi-region resiliency.
• Collaborative culture: Inclusive team that values autonomy, craftsmanship, and knowledge sharing.
• Growth: Strong mentorship, career development resources, and sustainable on-call practices.
