Job description

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.
Technical Responsibilities
  • Facilitate technical growth for all members of the development team
  • Develop, shape, and maintain technical processes and workflows
  • "Set the tone" in terms of craftsmanship standards and code quality
  • 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.
  • Active/thoughtful participation in discussions surrounding ticket specification, design review, etc.
  • Participate in active, intentional, and thorough code reviews.

Lead Responsibilities
  • Actively participate in GitHub discussions, issues, and pull requests
  • Provide technical support and guidance in both GitHub and Discord
  • Participate in growing the development team

Requirements
  • 5+ years building production, customer-facing React applications.
  • 7+ years of experience building production, customer-facing frontend applications (using React or any other frontend toolchain).
  • 1 year of TypeScript experience
  • Minimum 3 years working with any strongly typed programming language
  • Minimum 1 year leading or 2 years contributing to a web3-centric project
  • Very strong verbal and written communication skills.
  • Very strong understanding of idiomatic UI implementation patterns
  • Deep understanding of JavaScript and TypeScript
  • Strong understanding of the browser programming environment (the DOM, data-fetching APIs, storage APIs, sessions, HTTP, caching, etc).
  • Working understanding of public key cryptography (encrypting, signing, etc) and associated user flows
  • Desire to work in a semi-public-facing role as an OSS maintainer

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).
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
