Lead Software Development Engineer Jobs (NOW HIRING)

You'll join a high‑impact engineering organization building scalable, shareable technologies that power multiple product teams. As a full‑stack engineer with a strong affinity for front‑end 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.

• Design and implement extensible, shareable full‑stack features across multiple engineering projects, with a strong emphasis on front‑end architecture and user experience.
• Build high‑quality UI components and front‑end systems using modern frameworks (e.g., React).
• Serve as a go‑to technical expert for front‑end 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 front‑end 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 (front‑end and full‑stack) and propose adoption strategies.
• Own on‑call responsibilities, create and update runbooks/SOPs, and coach others on incident investigation.
• Author, review, and approve requirements and technical designs for multiple projects.
• Work cross‑functionally 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 non‑technical audiences.

• Extensive experience developing full‑stack software, including shareable front‑end and platform components.
• Deep expertise in front‑end 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 quality‑driven engineering (including front‑end 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, multi‑team projects.
• Proven ability to independently deliver high‑impact engineering work.

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).

This role is ideal for engineers who love full‑stack work but feel especially energized by front‑end 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 front‑end and back‑end.
