Salary Range:

We are looking for a Senior Engineer to join the Web Architecture team. Our team owns the architectural foundation that helps Reverb.com’s product teams ship fast, reliable, and scalable UI experiences. We strive to reduce complexity, define shared patterns, and build developer-friendly APIs and tools that power Reverb’s user-facing features.

The Web Architecture team sits between backend systems and frontend applications. We build and maintain the infrastructure, libraries, and interfaces that connect Reverb’s frontend developers to backend data, while ensuring that performance, observability, and usability are built in by default.

This is a full-time role reporting to the Web Architecture Engineering Manager. Our hybrid work model offers flexible workplace policies that can accommodate work from home candidates who are comfortable traveling to the office location 4+ times per month.

Responsibilities

• Build and evolve the internal APIs, frameworks, and libraries that power Reverb’s frontend experiences

• Help product engineers ship performant features quickly by providing clear architectural guidance and well-designed interfaces

• Improve the consistency and observability of data flows across our applications

• Contribute to the long-term evolution of our web stack (Rails, React, GraphQL), with an eye toward simplicity, performance, and reuse

• Reduce glue code and duplication by establishing shared patterns and usable abstractions

• Collaborate with engineers across product teams to align on technical approaches and developer needs

• Participate in site-wide on call rotations

Requirements

• Strong understanding of web fundamentals and the boundaries between frontend and backend systems

• Comfortable leading projects or initiatives with minimal guidance — we value engineers who bring clarity, form opinions, and follow through

• Strong written and verbal communication, especially in documentation and cross-team collaboration

• Experience writing maintainable JavaScript and working in a React-based application

• Comfortable navigating a Rails application and collaborating on backend contracts

• Familiarity with API design and integration — REST, GraphQL, or custom middle-layer patterns

• Experience contributing to shared libraries, tools, or frameworks used across teams

• A curiosity about improving developer experience through thoughtful abstractions, good defaults, and clear documentation

• Experience working with AWS or similar cloud providers

• Preferred but not required: Experience with Datadog, Docker, Kubernetes, and CircleCI/GitHub Actions
