• Use modern tools and frameworks (REACT and Node.js) to architect and develop applications from the ground up • Build and maintain automated evaluation pipelines (evals) for agent and skill outputs • Define strict input/output contracts for MCP tools and agent skills using typed schemas • Own the prompt engineering lifecycle for assigned tools and skills • Contribute to the team's MCP tooling catalog

• Entwicklung komplexer Frontend-Applikationen auf Basis von Javascript Frameworks • Realisierung anspruchsvoller Designkonzepte in Zusammenarbeit mit UX/UI-Experten • Anbindung externer Schnittstellen • Evaluierung von Lösungen für optimierte Projektplanung • Design, Implementierung, Test und Dokumentation neuer Features • Optimierung der vorhandenen Code-Basis • Implementierung von A/B-Tests mit dem Produktteam

• Work cross-functionally across Reddit Engineering to understand developer needs, quickly prototype solutions, and iterate based on feedback. • Own frontend development for internal developer tooling, from solution design and implementation through launch and long-term maintainability. • Build scalable, maintainable interfaces across both AI-powered developer workflows and the core non-AI systems engineers rely on every day. • Lead high-impact projects across Reddit’s developer tooling ecosystem by writing and reviewing code and design docs, aligning stakeholders, and making pragmatic technical tradeoffs. • Improve the team’s tools, processes, and best practices while raising the bar for quality, usability, and maintainability. • Mentor engineers and help shape a roadmap that reflects real developer needs and delivers meaningful improvements to Reddit’s engineering organization.

• Architect Financial Trust: Own the end-to-end financial experience for our Core, Plus, and Pro tiers. You’ll build the responsive interfaces and component logic that allow operators to navigate high-stakes distributions with confidence and clarity. • Product Design Strategy: Partner across the organization to ensure interface decisions move the needle on conversion, feature adoption, and retention. You are comfortable debating unit economics and UI. • AI-Native Prototyping: Leverage AI-forward development environments to rapidly test concepts as working prototypes, effectively removing the gap between product hypothesis and production-ready code. • Production-Level Craft: Work directly within our front-end architecture (React/TypeScript) to implement fluid interactions, elegant data visualizations, and predictable state management where user trust is paramount. • Scalable Product Architecture: Drive the evolution of the Pro product through components and views that handle property management at scale—addressing variable data, edge cases, and the sophisticated tools operators need. • Solve from First Principles: Use data, owner feedback, and cross-functional conversation to identify what needs to be designed and engineered before it becomes a support issue. • Autonomy and Ownership: You are responsible for shipping features and for the ultimate outcome. You’ll use your expertise, data, and user feedback to refine the user experience across multiple product areas to achieve business goals. • Systemic UI Thinking: Elevate Evolve’s core design system by translating design components and patterns into a robust, accessible, and highly reusable code library that maintains platform-wide consistency.
