Senior Front-End Engineer

Description

We’re looking for a Senior Front-End Engineer to lead the development of intuitive, performant UIs for our mobile attribution platform. You’ll own key parts of our front-end architecture, build data-rich dashboards and workflows in ReactJS with a Ruby on Rails backend, and collaborate closely with product managers, designers, and other engineers.

You should have deep experience with modern web development (HTML, CSS, JS/TS), a strong product sense, and a track record of shipping and maintaining complex features. You’ve likely worked on component systems, optimized performance at scale, and mentored other engineers.

This is a hands-on role with plenty of scope to shape user experience, front-end standards, and team direction. While we’re targeting senior engineers, we’re open to strong mid-level candidates who show leadership and ownership.

Team, Culture, and Product

We're a small engineering team looking to grow responsibly. We're a remote-only organization with most of the engineering team working from US timezones. We aim to help mobile app developers make data-driven decisions about their marketing in a secure, privacy-centric, user-friendly way. We encourage flexibility in working locations and hours but also make sure we all overlap at least briefly for a bit each day.

Responsibilities

• Lead major architecture and software design decisions
• Build composable, reusable front-end components for use in our marketing analytics dashboard
• Collaborate closely with designers, product managers, and backend developers to create user-friendly and visually appealing interfaces
• Write clear and maintainable documentation for front-end code
• Ensure test coverage for new features using appropriate testing tools (e.g., Jest)
• Employ feature flags to support trunk-based development workflows
• Adhere to and enforce code style guidelines and best practices
• Profile and debug UI performance issues

Requirements

• Proficiency in ReactJS, along with a strong foundation in HTML, CSS, and JavaScript
• A proven ability to work effectively in remote, collaborative environments
• Familiarity with Git and repository hosting platforms like GitHub
• Excellent organization and communication skills
• An appetite for learning, problem-solving, and contributing to a dynamic team environment

Nice-to-haves

• Experience integrating front-end components with Ruby on Rails backends
• Experience building and consuming REST APIs
• Experience with writing tests for JavaScript, preferably with Jest
• Experience with advanced topics in React such as the Context Api, Memoization and Virtualization
• Experience with Figma for design collaboration
• Experience working with in-house style guides

Benefits

• Annual budget for learning and personal development (conferences, books, classes, etc)
• Budget for fitness and well-being activities (gym memberships, fitness equipment)
• Unlimited vacation days and a vacation stipend to make sure you take time off (we recommend at least 20 days off per year)
• Team off-sites and other get-togethers
• Health Care Plan (Medical, Dental & Vision)
• Family Leave (Maternity, Paternity)
