JOB DESCRIPTION

At eBay, we're more than a global ecommerce leader — we’re changing the way the world shops and sells. Our platform empowers millions of buyers and sellers in more than 190 markets around the world. We’re committed to pushing boundaries and leaving our mark as we reinvent the future of ecommerce for enthusiasts.

Our customers are our compass, authenticity thrives, bold ideas are welcome, and everyone can bring their unique selves to work — every day. We're in this together, sustaining the future of our customers, our company, and our planet.

Join a team of passionate thinkers, innovators, and dreamers — and help us connect people and build communities to create economic opportunity for all.

We are looking for a dynamic, collaborative, and curious Staff Engineer to design, build and operate agent-based systems where agents use composable skills to accomplish end-to-end tasks. You will define AI workflows (planning, tool-use, memory, evaluation, governance), ship production services and APIs, and mentor teams to deliver reliable AI outcomes at global marketplace scale.

What you will do:

Architect agentic systems: plan/execute loops with explicit state; design composable skills; ground with memory and citations.
Build AI workflows: orchestrate task DAGs/state machines with retries, DLQ, idempotency, and SLAs.
Operate event pipelines: stream on Kafka with backpressure, observability, and failure recovery.
Ship services/APIs: expose REST/GraphQL endpoints for orchestration, inference, enrichment, and evaluation.
Implement RAG: index, retrieve, rank, and cite with policy guardrails and prompt hardening.
Evaluate/govern: offline/online evals, A/B/canary rollouts, audit trails, versioning, and risk classes.
Integrate stacks: backend (Node/Java/Scala/C++), web (Marko/React/TS), data (Oracle/NoSQL), platform (Kubernetes).
Mentor and OSS: share libraries/patterns; elevate reliability, safety, and engineering quality.

What you will bring:

BS/BA in Computer Science or related field 10 plus years work experience or MS with 8 plus experience
Experience on software design and development experience, solid foundation in computer science with strong proficiencies in system architecture, distributed systems, data structures, algorithms, OOPs, OOA/D and Functional programming
Experience with Node JS, Javascript, Java, Scala, Oracle/NOSQL DBs
Experience building web and RESTful applications
Experience working with frameworks such as Spring MVC
Knowledge of core CS concepts such as common data structures and algorithms
Strong applied experience. You've built, broken, and rebuilt software applications.
Creative thinker who knows how to create real-world products.
Code samples from private GitHub repos, side projects, and open source project contributions is a plus
Excellent decision-making, communication, collaboration, presentation, interpersonal and analytical skills.
