• Develop complete features: REST APIs in the Java backend and Angular components in the frontend • Implement and maintain REST endpoints consumed by the UI and by internal services • Build and evolve operational screens: dashboards, listings, filters, forms and data visualizations • Ensure authentication and access control in both backend and frontend layers (JWT) • Write unit and integration tests in the backend and unit tests in the frontend • Collaborate on defining API contracts between frontend and backend • Participate in code reviews and contribute to the evolution of team standards • Maintain code quality and consistency across both layers

• Own the design, development, and reliability of backend systems that power order management, trade matching, settlement, and market resolution for prediction markets • Architect distributed systems that enforce strict correctness guarantees across clearing, payout, and position management workflows • Drive the technical strategy for migrating from third-party venue participation to a fully Coinbase-operated exchange and clearing platform • Lead cross-functional collaboration with Product, Compliance, and Risk teams to ensure the platform meets regulatory requirements and launches with confidence • Shape engineering standards and practices across the Prediction Markets team, setting a high bar for code quality, system design, and operational rigor • Partner with engineers across Consumer & Business to identify shared infrastructure opportunities and reduce duplication across trading surfaces

• Backend: Application of design patterns, query optimization, API security, and a clear understanding of infrastructure and processing costs. • Frontend: Emphasis on performance (Core Web Vitals), Server-Side Rendering (SSR), state management, and responsiveness. • DevOps & Infrastructure Mindset: Strong foundation in CI/CD, monitoring and the ability to debug issues directly in the cloud environment to support application reliability and stability.

• Mandatory use of Cursor: all professionals must use Cursor (an AI-powered IDE) as the standard daily tool for development, testing, and automation. • Version control with Git/GitLab: strong knowledge of Git and working with GitLab workflows (branches, merge requests, code review). • Agile methodology: work in a Scrum/Kanban environment with active participation in ceremonies (planning, daily, review, retro). • Asynchronous collaboration: clear written communication and documentation of your own work. • Problem solving: analytical ability to investigate root causes of incidents, not just treat symptoms. • Proactivity: anticipate risks and propose improvements without waiting for direction; identify and raise issues before they escalate. • Autonomy: operate independently in an environment with limited documentation, making responsible decisions within your scope. • Adaptability: comfortable working in a changing context (ongoing stack and cloud migration). • Clear communication: translate technical issues for business stakeholders and align expectations. • Teamwork: collaborate openly, accept and provide code reviews, and share knowledge to reduce dependency on key individuals. • Ownership: take responsibility for deliveries and the stability of the environment. • Continuous learning: willingness to grow technically, especially in the use of AI and new platform technologies.
