About the Role

Fanatics is building a leading global digital sports platform. We ignite the passions of global sports fans and maximize the presence and reach for our hundreds of sports partners globally by offering products and services across Fanatics Commerce, Fanatics Collectibles, and Fanatics Betting & Gaming, allowing sports fans to Buy, Collect, and Bet. Fanatics Core builds the shared foundations — identity, payments, loyalty, wallet, data, and platform — that power sports betting, ecommerce, collectibles, and beyond. As a Senior Software Engineer, you will design, build, and operate the platforms and services that power the Fan Ecosystem. You will own significant technical surface area end to end, set the technical direction for projects that span multiple services and teams, and raise the engineering bar for those around you through mentorship, design leadership, and hands-on delivery. This is a hands-on, full-stack role with a backend center of gravity, primarily building high-throughput, high-availability services in Go, with meaningful contributions to the TypeScript/React front ends.

Responsibilities

Design, build, test, document, and operate high-quality, production-grade software with a focus on Go services and APIs
Own the technical design of medium-to-large features and systems: define the approach, weigh trade-offs, document decisions, and drive them to completion
Break down ambiguous problems into well-scoped, deliverable work for yourself and other engineers on the team
Lead and participate in design and architecture reviews; provide clear, constructive feedback that improves both the design and the designer
Set the standard in code reviews — for correctness, readability, testability, and operational safety
Mentor and grow engineers on the team; onboard new hires and act as a technical point of contact for your systems
Participate in and improve the on-call rotation: instrument your services, drive incident response, and lead blameless postmortems that result in real fixes
Improve reliability, performance, and cost of the systems you own; define and act on SLOs and operational excellence metrics
Identify and pay down technical debt, and make the case for the investments worth making
Partner closely with product managers, designers, and stakeholders to shape the roadmap and make technology decisions that grow the business
Influence and help define the principles, guidelines, and best practices of our engineering strategy — then hold the team to them
Develop deep understanding of our industry, product, feature set, and roadmap, and use it to make better technical decisions

Requirements

5+ years of professional software engineering experience building and operating production systems
Strong, demonstrated proficiency in Go (Golang) — required. You have built and shipped production services in Go and can speak to concurrency patterns, error handling, testing, profiling, and performance tuning in the language
Proven experience designing, building, and scaling backend services and APIs (REST and/or gRPC) in a distributed, microservices environment
Demonstrated proficiency in JavaScript or TypeScript, and experience with React or another modern front-end framework
Solid grounding in data stores and messaging: relational and/or NoSQL databases, caching, and event streaming (e.g. Kafka, SQS/SNS)
Experience with cloud infrastructure (AWS, GCP, or Azure), containers, CI/CD, and infrastructure-as-code
Strong operational instincts: observability, monitoring, alerting, debugging production issues under pressure
Track record of leading projects with multiple contributors and delivering them on time without sacrificing quality
Familiar with Agile software product delivery and SCRUM methodology
Able to effectively work cross-functionally within an enterprise environment
Experience building or integrating with identity and access management systems — authentication, authorization, SSO, and account lifecycle
Hands-on familiarity with identity standards and protocols: OAuth 2.0, OpenID Connect, SAML, JWT, MFA, session and token lifecycle management
Experience with identity providers and CIAM platforms (e.g. Okta, Auth0, ForgeRock, AWS Cognito, Ping) or with building an in-house identity platform
Experience with account security, fraud prevention, PII handling, or regulatory/compliance-driven engineering (KYC, GDPR, CCPA)
Experience designing systems that serve high-traffic, consumer-facing products with spiky, event-driven load
Experience with platform or shared-services work where your consumers are other engineering teams
Experience working in a start-up environment
Experience in sports, commerce, media, or another consumer-scale domain
