Software Engineer, Frontend

About the role

You will own the full lifecycle of user-facing features from initial discovery through production deployment and monitoring. You will translate ambiguous product goals into resilient frontend architectures while collaborating daily with product designers to refine the user experience. You will contribute directly to our backend REST API work using Next.js and TypeScript, ensuring seamless integration between frontend and backend systems. You will champion code quality and maintainability, guiding the evolution of our design system and establishing best practices across the team. You will proactively identify and fix issues in the product experience without waiting for direction, taking ownership of problems end to end. You will leverage Dust as our primary tool for coding, debugging, and knowledge work to accelerate development and incident response. You will ensure that applications built are scalable, performant, and accessible across a diverse set of users and environments.
