We're looking for a Senior Software Engineer (Node.js / Backend for Frontend) to join our Sportsbook Core Apps engineering team. You'll be working on foundational engineering, focusing on improving the Node.js services layer that sits between our Sportsbook clients and the broader backend platform — enabling faster content delivery, cleaner data contracts, and a more reliable experience for millions of bettors.
Working across a suite of Node.js BFF services, you'll own cross-cutting concerns: caching strategy, runtime health, shared patterns, and the architectural building blocks that feature teams depend on. You'll collaborate closely with engineers across the org to ensure these services are fast, secure, and easy to build on top of. We're looking for skilled engineers who are empathetic communicators with a commitment to continuous improvement and engineering excellence.
The ideal candidate has significant experience building and operating production Node.js services, can propose pragmatic solutions to performance and reliability challenges, and enjoys mentoring others and raising quality standards. As a member of this team, you will strengthen the foundations of our services platform, enabling FanDuel engineers to deliver features more effectively while maintaining quality and operational readiness.
Responsibilities- Evolving the caching and data-aggregation patterns used across our BFF services (including multi-layer caching strategies and proxy service design)
- Driving cross-cutting improvements across multiple Node.js services simultaneously—runtime upgrades, dependency management, security patching, and shared library evolution
- Contributing to architectural decisions (ADRs) and patterns that reduce integration friction and improve consistency for feature teams building on these services
- Building and maintaining shared tooling, libraries, and scaffolding that support teams across the sportsbook platform
- Improving developer experience through better CI reliability, release pipeline automation, and build tooling (NX monorepo)
- Supporting continuous improvement initiatives that raise quality, reduce toil, and improve operational readiness within the domain
- Joining our on‑call rota, sharing out‑of‑hours support duties as part of our incident response process
- Contribute meaningfully to technical design discussions and propose pragmatic solutions aligned with our technical vision
- Take ownership of delivering platform improvements end to end, including measurement, rollout, and iteration
- Mentor and support other engineers, raising the bar through thoughtful reviews, coaching, and knowledge-sharing
- Significant experience building and operating production Node.js services (REST/GraphQL APIs, BFF patterns, or similar)
- Strong TypeScript skills and a solid understanding of service architecture, maintainable code practices, and API design at scale
- Experience with caching strategies in distributed systems (e.g. Redis, in-memory caches, CDN-level caching) and the trade‑offs involved
- Comfort working across multiple services or repos simultaneously and coordinating changes that span team boundaries
- Familiarity with AWS Lambda, containerisation, or similar serverless/cloud-native infrastructure
- Experience working in Agile teams and contributing to collaborative technical standards
- A quality‑focused mindset with strong problem‑solving skills and the ability to evaluate trade‑offs in ambiguous situations
- Experience with React or React Native is a plus but not essential
