REQUIREMENTS

• 5+ years of professional software engineering experience, with significant full-stack work
• Expert-level React and TypeScript with a deep understanding of modern patterns and performance optimization
• Strong backend development experience with direct database integration and API design
• Experience designing centralized business logic layers reusable across multiple platforms (SSR, APIs)
• Database expertise: Schema design, query optimization, PostgreSQL
• Production experience with real-time web technologies (WebSockets, SSE, WebRTC)
• Deep understanding of web performance (Core Web Vitals, bundle optimization, lazy loading, code splitting)
• Experience with state management at scale (Redux, Zustand, Jotai, Recoil, or similar)
• Strong experience in systems-level programming for performance-critical applications, with proficiency in low-level optimization techniques including parallel processing, memory management, profiling, and benchmarking.
• Experience building robust file processing systems including upload/download handling, media compression and format conversion, file validation, and quality checks.
• Familiarity with cloud infrastructure, CI/CD pipelines, containerization, and monitoring/observability practices.

RESPONSIBILITIES

Technical Leadership & Architecture

• Participate in shaping the technical vision for rebuilding our asset management platform from scratch
• Design a centralized data architecture with direct database integration and shared business logic reusable across SSR and future GraphQL.
• Make critical architectural decisions, including tech stack selection, state management patterns, data layer design, and performance optimization strategies.
• Ensure future-proof architecture compatible with GraphQL migration while optimizing for immediate SSR performance
• Define coding standards and best practices for the team, ensuring maintainable, scalable code
• Collaborate with product and design teams to translate requirements into technical specifications

Full-stack Development

Frontend

• Build modern React-based apps with real-time capabilities using technologies like TanStack ecosystem, Server-Sent Events, and BroadcastChannel API
• Build performant UI components with smooth data loading patterns, virtualization, and responsive user interactions
• Optimize bundle size, lazy loading, and code splitting for <1s Time to Interactive

Backend Integration

• Build a shared business logic layer reusable across multiple service boundaries and rendering contexts
• Design database schema and ORM integration
• Develop background job processing systems for asynchronous workflows

Performance-Critical Systems (Rust/Zig)

• Design and optimize performance-critical operations using systems-level programming and worker-based architectures to keep heavy processing off the main thread
• Implement WASM modules for browser-based file processing with near-native performance
• Build batch processing systems capable of handling large-scale concurrent operations efficiently
• Profile and eliminate performance bottlenecks across critical data processing and transformation pipelines
