Job description

Frontend Developer - UI & Design Systems

Since its release in 2014, Spark’s initial project Rock RMS has been leading the innovation curve of the Church Management Space. Hundreds of ministries have been impacted by this open‑source revolution. It’s amazing what God has done, and we believe He’s just getting started.

This position is a key hire that will allow Spark to take Rock to the next level by owning and evolving our front‑end design system in code. You’ll be part of the development team, responsible for maintaining reusable UI/CSS components, building new ones, and acting as the bridge between our designers and developers. Think of it as building something like Bootstrap, but for churches. We’re looking for a detail‑oriented, self‑driven front‑ender who’s passionate about clean, scalable code and pixel‑perfect UIs.

What You'll Be Doing:

• Developing new UI components—styled, documented, and tested—for use across Rock RMS
• Collaborating closely with designers to translate mockups and style guides into production‑ready code
• Partnering with backend and full‑stack developers to integrate components into the application
• Writing clear documentation and usage examples for every component
• Participating in code reviews, ensuring CSS/HTML/JS best practices and accessibility standards

You’ll fit right in if you:

• Are an expert in CSS (including preprocessors like Less or Sass)
• Have hands‑on experience building and maintaining a design system or component library
• Communicate effectively between design and development teams
• Thrive in a fast-paced development environment
• Are proactive about learning new front‑end tools and techniques

You'll work well if you:

• Are proficient with Vue.js or similar frameworks
• Are an expert in Bootstrap and Tailwind
• Use Git for version control and collaborate via pull requests

Bonus Points For:

• You’ve got a background in graphic or visual design
• You’ve created custom themes or utility‑first toolkits (e.g., Tailwind plugins)
• You’ve contributed to open‑source front‑end projects
• You’re familiar with church‑management or CRM systems

Location and Application: This position is located in Phoenix West Valley. We offer competitive salaries to qualified applicants.
