Job description

What You'll Be Part Of:

You'll join a highimpact engineering organization building scalable, shareable technologies that power multiple product teams. As a fullstack engineer with a strong affinity for frontend development, you'll shape user experiences, define UI architecture, and build reusable components that accelerate development across the company. Your work will influence product direction, elevate engineering productivity, and help define the next generation of platform and UI capabilities.

Responsibilities:
  • Design and implement extensible, shareable fullstack features across multiple engineering projects, with a strong emphasis on frontend architecture and user experience.
  • Build highquality UI components and frontend systems using modern frameworks (e.g., React).
  • Serve as a goto technical expert for frontend patterns, performance, accessibility, and best practices.
  • Review code with prescriptive, actionable feedback; contribute to coding standards and UI/UX guidelines.
  • Drive improvements to automation systems and testing frameworks, including frontend testing strategies.
  • Explore and evaluate AI technologies to enhance team productivity and effectiveness.
  • Create space for teammates to adopt AI tooling through pairing, demos, and documentation.
  • Lead research into external technologies (frontend and fullstack) and propose adoption strategies.
  • Own oncall responsibilities, create and update runbooks/SOPs, and coach others on incident investigation.
  • Author, review, and approve requirements and technical designs for multiple projects.
  • Work crossfunctionally to align partners and stakeholders to project vision, mission, and strategy.
  • Mentor less experienced engineers in communication, design, UI engineering, and execution.
  • Communicate clearly and effectively, tailoring messaging to technical and nontechnical audiences.
Qualifications and Education Requirements:
  • Extensive experience developing fullstack software, including shareable frontend and platform components.
  • Deep expertise in frontend engineering using modern frameworks such as **React**, plus strong understanding of JavaScript/TypeScript, state management, and UI performance.
  • Strong understanding of test automation systems, maintainable test patterns, and qualitydriven engineering (including frontend testing frameworks like Jest, React Testing Library, Cypress).
  • Strong knowledge of data structures, algorithms, and performance optimization techniques.
  • Experience authoring and reviewing technical designs for complex, multiteam projects.
  • Proven ability to independently deliver highimpact engineering work.
Preferred Skills:

Frontend Development

  • Core Languages: HTML5, CSS3, and JavaScript (ES6+).
  • Frameworks/Libraries: React
  • Design Principles: Responsive web design and mobile-first development.

Backend Development

  • Languages & Environments: Node.js (JavaScript/TypeScript), Python (Django/Flask), or Java (Spring Boot).
  • API Architecture: RESTful APIs (standard) and GraphQL (modern alternative).
  • Server Logic: Authentication (JWT/OAuth), authorization, and middleware.

Database Management

  • Relational (SQL): PostgreSQL, MySQL, or SQL Server for structured data.
  • Non-Relational (NoSQL): Redis for caching.
  • Querying: Proficiency in writing SQL queries and utilizing ORMs (like Prisma or Sequelize).
Additional Notes:

This role is ideal for engineers who love fullstack work but feel especially energized by frontend engineering, user experience, and building UI systems that scale across teams. Senior SDEs in this domain are expected to lead by example, elevate engineering quality, and drive innovation across both the frontend and backend.
