Relay is building the web3 messenger. We are looking for talented and motivated front-end engineers of all experience levels. Relay engineers thrive in a high-growth, high-velocity environment where success depends on the highest levels of communication, code quality, and pragmatism. Each engineer must be able to individually own a slice of the Relay codebase while also maintaining a working knowledge of others.
Accordingly, Relay is looking for team members who are not only highly-skilled individual contributors but also strong collaborators and communicators.
- Carefully implement critical UI components, shared functionality, and certain subsystems (like monitoring, testing, validation, etc)
- Rapidly implement functional UI elements from design mocks and workflow diagrams, with an eye toward correctness and readability.
- “Set the tone” in terms of craftsmanship standards and code quality
- Active/thoughtful participation in discussion surrounding ticket specification, design review, etc.
- Participate in active, intentional, and thorough code reviews.
- 5+ years of experience building production React applications
- 1 year of Type Script experience
- Minimum 3 years working with any strongly typed programming language
- Very strong verbal and written communication skills.
- Very strong understanding of idiomatic UI implementation patterns

Relay's benefits include unlimited and encouraged time off, 100% company-paid medical, dental, & vision for you and your dependents, 2-3x/week company lunches at local restaurants, and for remote employees: up to $2,000 USD home office setup stipend (all benefits are subject to applicable taxes and based on eligibility).
