Senior Software Engineer (React)

PrizePicks is the fastest-growing sports company in North America, recognized for its leading platform in Daily Fantasy Sports. They are seeking a Senior Software Engineer with strong TypeScript and React expertise to develop internal tooling and platforms that support promotional and partner programs, while also guiding junior engineers and contributing to architectural decisions.

Responsibilities:

• Own feature development
• Write high-quality code
• Integrate with third-party platforms
• Build the affiliate partner platform
• Contribute to architecture
• Improve quality proactively
• Guide junior engineers
• Collaborate cross-functionally
• Participate in on-call rotation
• Build team knowledge

Requirements:

• 3–5 years of professional software engineering experience, with meaningful time building React web applications — ideally including internal tools, admin platforms, or operational dashboards
• History of delivering complex features within a software team to drive business outcomes
• Experience breaking down ambiguous operational requirements into concrete technical plans
• Exposure to integrating with third-party platforms and managing the data contracts between systems
• Advanced proficiency in TypeScript — you write clean, type-safe, production-quality code
• Strong React experience — deep understanding of component lifecycle, hooks, performance optimization, and patterns for data-heavy, form-heavy internal applications
• Experience with RTK Query, React Query, or similar data-fetching and caching layers for complex admin UIs
• Experience building and consuming REST or GraphQL APIs; comfort reasoning about backend data models even if your primary focus is the frontend
• Familiarity with Braze or similar CRM/messaging platforms — understanding how promotions, segments, and campaigns are structured and delivered
• Experience with state management solutions suited to complex, multi-step workflows (form state, async data, optimistic updates)
• Solid testing practices — unit and component testing with Jest; familiarity with Playwright, Cypress, or similar E2E frameworks
• Familiarity with CI/CD pipelines, containerized local dev environments, and web deployment workflows
• Working knowledge of React Native — enough to contribute to mobile-facing promotional surfaces when needed
• Autonomous — you can take an ambiguous operational problem and drive it to a well-defined technical solution
• Comfortable working directly with internal stakeholders to validate requirements and surface tradeoffs
• Strong written communicator, especially important in a fully remote environment
• Able to balance deep technical work with collaborative design and planning
• Prior experience building internal tooling, back-office platforms, or operational dashboards at scale
• Hands-on experience with Braze — building integrations, managing campaign data, or working with its API
• Familiarity with Go or Ruby/Rails at a read level — enough to navigate BFF and monolith APIs, trace data flows, and collaborate effectively with backend engineers without needing a translator
• Experience with affiliate or partner program platforms, payout workflows, or performance tracking systems
• Familiarity with financial data considerations — auditability, reconciliation, and accuracy requirements around payouts
• Comfort working in Kubernetes-based deploy environments (K8s manifests, ArgoCD) — you don't need to own it, but you're not intimidated by it
• Experience using AI-assisted development tools for coding, planning, and scoping work
• Prior experience working in a remote engineering organization
