We are seeking a senior-level product engineer to join the MxU team and help build the future of church technology. This is a hands-on engineering role for someone who wants to shape product direction, talk directly with the people closest to the customer, and ship production software across web, desktop, and mobile.

About MxU

MxU was founded in 2019 to serve church production, worship, and tech teams through practical training and purpose-built software. We have served over a hundred thousand church volunteers and staff through our training platform, courses, and member content.

Our product is expanding beyond training into a broader operating system for church production teams: realtime dashboards, service planning, Planning Center-connected workflows, production tools, desktop integrations, mobile experiences, and operational analytics. Churches rely on this work every week, often live during services, so quality, clarity, and practical reliability matter.

We are a small team of high-level contributors. The work is broad, the ownership is high, and the best ideas can come from anyone.

The Role

At MxU, a Senior Product Engineer owns full features from rough idea to production-ready release. You will work with non-technical team members to understand customer pain, shape product direction, design the experience, and then implement the feature across the relevant parts of the stack.

This role is a fit for someone who enjoys both sides of product engineering: turning ambiguous customer needs into a crisp product path, then getting deep into code, tests, data models, APIs, UI details, and production behavior.

You will work closely with the CTO to keep product decisions, implementation choices, and technical architecture aligned as the product grows.

Reports to: CTO
Salary range: $120,000 - $220,000
Location: Remote, United States
Type: Contract to hire

What You Will Work On

Build full-stack product features in our Rails web app, including API, database, background job, realtime, and browser UI work.
Build and refine realtime dashboards, control surfaces, and public display experiences.
Work on broad surface areas of the product including integrations, learning management system, service planning and more.
Contribute to the Tauri desktop app when features need native macOS behavior.
Contribute to the Expo React Native mobile app when features need native iOS or Android experiences.
Use observability, logs, customer evidence, and production data to debug real problems.
Keep the product cohesive by reusing existing patterns and simplifying the system.

Our Stack

Ruby on Rails monolith
Limited React front end for complex UI
React native / expo iOS and Android apps
Tauri / Rust macOS app

Experience And Requirements

Deep full-stack Ruby on Rails experience (required).
Strong product judgment and ability to shape ambiguous ideas into usable software.
Comfortable with modern browser UI work, including React, Inertia, Hotwire/Stimulus, Tailwind CSS, and Vite-style tooling.
Strong database and backend instincts: data modeling, migrations, background jobs, API boundaries, tests, and production debugging.
Comfortable owning features that cross frontend, backend, and operational concerns.
Able to work with non-technical teammates and translate customer context into product and implementation decisions.
AI-assisted development experience, including the judgment to use AI effectively without outsourcing responsibility.
React Native experience is a strong plus.
Tauri, Rust, macOS desktop, local network, or native integration experience is a strong plus.
Experience with realtime systems, websockets, dashboards, or production-control workflows is a strong plus.

Flexible remote work.
Small team with meaningful product surface area.
