• Experience building complex web applications at scale.

• Deep understanding of state management and modern frontend architecture.

• Strong product sense and ability to make informed UX decisions.

• Experience working closely with backend systems and APIs.

• Ability to operate independently and thrive in ambiguous environments.

• Strong attention to detail and commitment to high-quality user experiences.

• Excellent communication skills and collaborative mindset.

Nice to Have

• Exposure to AI-powered products or developer tools.

• Familiarity with modern frontend ecosystems, including advanced caching and synchronization strategies.

• Design experience or strong visual product instincts.

• Experience helping establish engineering standards in early-stage teams.

Why Join?
