Senior Front End Engineer

Jobtailor; Deutschland; Remote; EUR 121.000 - 164.000; Vollzeit

Zusammenfassung

PrizePicks is seeking an experienced Senior React Native Engineer to design and implement complex, performant mobile features in a fully remote environment. You will own end-to-end feature delivery, optimize performance, and mentor others while collaborating with product, design, QA, and other engineers.

You'll work with Expo, TypeScript, and monorepo tooling to scale mobile apps serving millions of users, while shaping engineering practices around testing, accessibility, and deployment

Qualifikationen

• 5–8 years of professional software engineering experience with production React Native apps.
• Proven track record of owning and delivering complex, multi-component mobile features in a team.
• Experience across the full mobile development lifecycle — from development through app store submission and post-release monitoring.
• Experience building mobile applications backed by large-scale, high-throughput distributed systems serving millions of users.
• Expert-level TypeScript proficiency — clean, type-safe, well-tested production code.
• Deep React Native expertise, including performance optimization, native module integration, complex animations, and platform-specific considerations.
• Strong experience with Expo and its ecosystem.
• Proficiency with monorepo tooling (Yarn workspaces or similar).
• Solid understanding of mobile testing strategies, including Jest and Maestro for E2E testing.
• Experience with CI/CD for mobile and Expo/EAS workflows, including build pipelines, OTA updates, and app store deployment.
• Understanding of mobile observability, including crash reporting, performance monitoring, and analytics integration.
• Comfortable working autonomously with minimal direction on ambiguous problems.
• Effective communicator able to articulate technical decisions to engineers and non-technical stakeholders.
• Experience working in a fully remote engineering organization.
• Able to context-switch between deep technical work and collaborative planning.
• Experience leveraging AI-assisted development tools across coding, planning, scoping, and code review is a standout qualification.
• Experience integrating AI tooling into engineering workflows is a standalone qualification.
• Must be authorized to work for any employer in the U.S.; PrizePicks is unable to sponsor or take over sponsorship of an employment Visa

Aufgaben
