Requirements
  • Several years of professional front-end engineering experience (or equivalent), with deep hands-on experience building production applications using modern JavaScript / TypeScript frameworks (e.g. React, Next.js).
  • Strong mastery of HTML, CSS, and modern styling approaches (CSS-in-JS, design tokens, component-based styling), with a deep understanding of browser behavior, layout, and performance.
  • Proven experience owning and evolving complex front-end systems, not just implementing features.
  • Experience integrating with backend APIs (REST / GraphQL / streaming APIs) and collaborating closely with backend teams on system design.
  • Experience building or supporting realtime, streaming, or AI-driven UI components.
  • Strong product and UX instincts - comfortable working with designers and product managers to refine flows, interactions, and edge cases.
  • High standards for code quality and maintainability; experience with testing strategies, CI/CD workflows, and version control (Git).
  • Strong interest in - and comfort with - AI-augmented engineering workflows, using AI tools to accelerate development without sacrificing correctness or quality.
Responsibilities
  • Own the front-end architecture for core product surfaces, making thoughtful decisions around state management, data fetching, performance, and scalability.
  • Build responsive, accessible, and high-performance UIs using modern front-end technologies (e.g. React, Next.js, TypeScript).
  • Design, develop, and evolve a shared component library / design system, ensuring consistency, usability, and maintainability as the product grows.
  • Collaborate closely with backend engineers to define API contracts (REST / SSE / GraphQL) and ensure smooth, efficient data flow between frontend and backend.
  • Build AI-first, realtime user experiences, including streaming and interactive components that respond dynamically to backend and model outputs.
  • Leverage AI-assisted development tools (code generation, refactoring, testing, linting, review) as a core part of your workflow to increase velocity while maintaining high code quality.
  • Partner deeply with Product and Design to translate UX concepts and wireframes into production-ready features, proactively identifying edge cases, trade-offs, and implementation risks.
  • Drive performance, accessibility, and quality across the front-end stack (load times, responsiveness, cross-browser support, a11y).
  • Set and uphold high engineering standards: write clean, testable code; lead by example in code reviews; help define front-end best practices and patterns.
Desired Qualifications
  • Experience building conversational or chat-based interfaces, including managing complex client-side state, streaming responses, and dynamic message flows (e.g. ChatGPT-style UIs).
  • Prior ownership of a design system or shared component library used by multiple engineers or teams.
  • Deep experience with TypeScript in large-scale front-end codebases.
  • Strong background in performance optimization, accessibility (a11y), and cross-browser support at scale.
  • Experience working in a fast-moving startup or AI-native product environment.
  • Strong communication skills - able to clearly articulate UI constraints, technical trade-offs, and architectural decisions to cross-functional partners.

ST Labs develops blockchain applications and token-based networks on the Cosmos blockchain. They work with founders and teams to build decentralized, consensus-driven, secure business platforms, covering not only the technical development of dApps but also the economics, governance, and community structures needed for networks to scale. Using the Cosmos tech stack (Cosmos SDK), ST Labs acts as a technical partner to design, deploy, and govern interoperable, application-specific blockchains, with a team of blockchain engineers and research analysts who aim to reshape consumer and enterprise models through permissionless innovation. Their goal is to help create global ecosystems that connect the communities around various applications, enabling scalable and interconnected decentralized platforms.
