Senior Software Engineer (React)

Responsibilities

• Write high-quality code Produce TypeScript and React code that is clean, performant, well-tested, and raises the bar for the codebase. Internal tools carry real operational weight - quality here directly affects the teams relying on them.
• Integrate with third-party platforms Build and maintain integrations with platforms like Braze and Appsflyer. Coordinate how promotions are created, targeted, and delivered to users. Understand the data contracts between internal systems and external platforms, and build accordingly.
• Contribute to architecture Participate in team-level architectural decisions around internal application patterns, data modeling, API design, and third-party integration strategies.
• Improve quality proactively Identify opportunities to improve reliability, data accuracy, UI performance, and developer experience in our internal tooling - and act on them.
• Guide junior engineers Provide technical guidance to Software Engineers I and II through thorough code reviews, pairing sessions, and design feedback.
• Collaborate cross-functionally Work closely with Product, Marketing, and Partnerships to understand operational workflows and translate them into well-designed tooling. You're comfortable sitting in a room with non-technical stakeholders and turning fuzzy requirements into a concrete build plan.
• Participate in on-call rotation Take increasing ownership of incident response, contributing to root cause analysis and systemic improvements - including issues with promotion issuance, payout processing, or integration failures.
• Build team knowledge Document technical decisions, data models, and integration patterns to strengthen your team's shared understanding.
• What You Have

• 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 - u
