Original 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.

About the team:

eBay’s Developer Ecosystem team offers resources that help developers create solutions to make buying and selling on eBay faster and easier. The team builds and manages eBay’s Public APIs and eBay’s world-class Developer Portal, which helps onboard new developers, gets them started with eBay APIs, and answers their questions about our products. APIs are first-class products at eBay. APIs allow our developer community to create powerful experiences and manage their eBay business at scale. Our goal is a large ecosystem of developer applications that contribute to our buyers and sellers.

About the Role:

We are seeking a highly experienced Software Design Engineer to design and build scalable, high-performance systems & APIs that power seamless end-to-end customer experiences.

This is an individual contributor role for a hands-on technical leader who drives architecture, solves complex distributed systems challenges, and partners multi-functionally to deliver customer-first solutions at scale. A key focus of this role is designing clear, scalable, and well-governed APIs and service contracts that enable consistent, high-quality integration across systems.

You will influence system design, internal API standards (REST, GraphQL), and long-term technical strategy while remaining deeply engaged in implementation.

What You’ll Do:

Design and implement scalable, resilient fullstack systems supporting core platform capabilities
Architect high-traffic, distributed systems across multiple domains
Lead the design of robust, intuitive, and evolvable APIs and service contracts
Define and enforce standards for API design, documentation, versioning, observability and governance
Drive clarity and consistency in technical specifications, ensuring they are precise, consumable, and scalable
Write high-quality, maintainable, and performant code
Lead complex technical initiatives end-to-end, from design through production rollout
Apply SOLID principles and advanced design patterns to ensure clean, extensible architectures
Design multi-threaded and highly concurrent systems with strong performance guarantees
Contribute to enterprise architecture decisions and cross-domain technical alignment
Collaborate with Product, UX, Data, and Business teams to translate requirements into scalable technical solutions
Conduct architecture and code reviews to raise engineering standards
Mentor engineers and serve as a technical role model across teams
Proactively identify and resolve system bottlenecks, reliability risks, and scaling challenges

What you will bring:

10+ years of experience in the software industry
Deep expertise in at least one of: Java, Python, or Kotlin
Strong knowledge of software design principles (SOLID) and design patterns
Deep expertise in GraphQL schema composition and evolution, including building user-focused APIs, optimizing query performance, and maintaining backward compatibility at scale.
Proven ability to design and operate GraphQL APIs in large-scale systems, with strong understanding of API architecture (alongside REST/RPC), versioning strategies, and efficient data fetching patterns.
Expert-level understanding of:
- Multi-threading and concurrency
- Distributed systems design
- Enterprise-scale architecture
Demonstrated ability to create clear, consistent, and well-documented service contracts and technical specifications
Experience driving API design standards, consistency, and governance across teams
Experience with agentic coding assistants like claude code, cursor or github copilot
Proven experience building and scaling high-traffic, transaction-heavy systems
Strong understanding of system performance, availability, and observability
Experience working in Agile/Scrum environments

Nice to Have:

Experience with Federated GraphQL architectures (e.g., Apollo Federation or similar)
Experience designing and scaling modern frontend systems using TypeScript/JavaScript with frameworks such as React (or similar)
Experience with microservices and cloud-native architectures
Background in large-scale platforms or multi-tenant architectures
Experience with search systems, recommendation engines, pricing systems, or payment flows
Experience driving technical strategy across multiple team

Technical Leadership Expectations:

Acts as a system-level problem solver - designs for scale, resilience, and long-term maintainability
Champions high-quality API design and treats APIs as long-lived products
Drives clarity, precision, and standardization in system design and specifications
Makes sound architectural trade-offs balancing performance, cost, and development velocity
Customer-obsessed outlook - understands how technical decisions impact performance, reliability, and user experience
Drives technical clarity in ambiguous, high-complexity problem spaces
Sets the standard for engineering quality and operational excellence
