What You'll Be Doing

• Design and build the API and serving layer that powers data-intensive product experiences, using REST and/or GraphQL APIs to efficiently expose data, insights, and analytics to applications.
• Develop highly scalable backend services using Java and Kotlin, with a focus on API-first architecture, performance, reliability, and extensibility.
• Build new data-driven product experiences that transform large volumes of operational and analytical data into actionable insights, scoring, dashboards, and customer workflows.
• Design and optimize data access patterns across APIs, relational databases, caching layers, and analytical data sources to support enterprise-scale workloads.
• Build and maintain React/TypeScript user experiences, including dashboards, forms, workflows, status indicators, and drill-down experiences, while contributing to reusable components and established frontend architecture and data-flow patterns.
• Establish clear and maintainable contracts and boundaries between frontend applications, APIs, and backend services.
• Participate in architecture and design reviews as we take new products from early-stage development through general availability and enterprise scale.
• Identify and solve performance and scalability bottlenecks across backend services, APIs, databases, data access patterns, and front-end applications.
• Troubleshoot complex production issues across the full technical stack using logs, metrics, traces, query analysis, browser debugging, and other observability tools.
• Instrument front-end applications with appropriate observability and telemetry to understand errors, performance, and customer experience in production.
• Leverage AI-assisted development tools and techniques to improve engineering productivity and accelerate product development.
• Participate in code reviews, document technical decisions and processes, and contribute to cross-team engineering initiatives.
• Take ownership of features end-to-end—from architecture and implementation through testing, deployment, monitoring, and production troubleshooting.
• Other duties as needed.

About You

• 10+ years of software development experience building production applications, with strong experience in Java. Kotlin experience is a plus but not required.

• Strong TypeScript/JavaScript fundamentals, including using TypeScript to establish maintainable, reusable contracts and clear boundaries across components, APIs, and application layers.
• Strong understanding of HTML, CSS, browser fundamentals, and accessibility, beyond simply working within a React framework.
• Experience building reusable React components and working within established front-end architectures and data-flow patterns.
