StubHub is seeking a Senior Software Engineer to join the Core Platform - Streaming & Storage team. This role focuses on designing, building, and evolving the streaming, messaging, and storage platforms that serve as critical infrastructure for StubHub's engineering organization.
You will lead the design and delivery of scalable platform capabilities, partner with engineering teams on complex performance and reliability challenges, and help modernize services at the core of StubHub's distributed systems. A key initiative involves decomposing large monolithic SQL Server data stores into purpose-built storage systems, supported by mature streaming solutions and reliable data access layers.
The team owns foundational products including message queues, DQL, retry infrastructure, message versioning, messaging control planes, and storage platforms such as key-value databases, distributed caches, and blob storage. These systems support high-scale, reliable, event-driven services and business-critical workflows across listings, transactions, fulfillment, and customer experiences.
Key responsibilities include:
- Design and develop SDKs, services, shared packages, and tools to enhance engineering efficiency and productivity
- Develop an intuitive cross-language performant runtime environment for business/customer-facing services
- Architect and implement high-performance, scalable services actively used by internal customers
- Serve as a subject matter expert in distributed caching and messaging with deep understanding of associated design patterns
- Collaborate closely with engineering teams to identify technical inefficiencies and propose scalable solutions
- Drive initiatives to improve performance and scalability across the platform
- Champion best practices in software development and quality standards
- Mentor junior engineers and foster a positive, inclusive team culture
This role is ideal for an engineer who enjoys solving deep infrastructure and backend problems, setting technical direction, influencing architecture across teams, and delivering platform capabilities with measurable business impact.
Location: Hybrid (3 days in office, 2 days remote). Options include New York, NY; Century City, CA; Aliso Viejo, CA; or San Francisco, CA.
Requirements:
- 5-6+ years of professional software development experience
- Experience developing robust, mission-critical systems using one or multiple general-purpose programming languages (C/C++, Java, C#, or other OOP languages)
- Expertise in designing and optimizing distributed systems, including microservices architectures, caching strategies, and message queuing systems
- Demonstrated ability to analyze and enhance system scalability, reliability, and performance metrics
- Previous experience designing and developing solutions to complex problems with significant business impact
- Strong understanding of how systems interact with the broader production environment, including dependencies and platform primitives
- Proven ability to learn other coding languages, platforms, frameworks, and tools
- Strong communication skills and ability to collaborate effectively with cross-functional teams
- Experience owning projects from initial idea through production
- Experience mentoring junior engineers
