Maintain high code quality. Write clean, maintainable, and well-tested code, and participate in code reviews and technical design discussions.
Test and debug. Build automated tests, monitor system performance, and troubleshoot issues in production environments.
Contribute to system design. Engage in hands-on coding and architectural decisions to ensure reliability, security, and scalability.
Grow the team. Support a strong engineering culture through mentorship, thoughtful reviews, and shared ownership of technical standards.
Qualifications:
5+ years of software engineering experience with a track record of shipping production systems or features

Strong working knowledge of HTML, CSS, JavaScript, and modern frontend frameworks or libraries, with comfort building user-facing experiences
Solid system design, coding, and testing skills across both frontend and backend
Proven ability to collaborate effectively with product, design, and other engineering partners
