Senior Ruby Developer Jobs in Detroit, MI (NOW HIRING)

Belle is a fast growing engagement company that is revolutionizing home healthcare – and it all begins with the feet. With 25M+ U.S. seniors no longer able to see or reach their feet, a lack of self care and mobility challenges cost the health insurance plans $38B+ in preventable medical spending every year.

Belle trains and manages a network of nail technicians or “Community Health Workers” who provide in‑home foot care (aka medical pedicures). Belle uses cutting edge data science to identify those most in need on behalf of health plans and deploys its services accordingly. While in the home, Community Health Workers complete assessments and screenings, often being the first to identify emerging issues below and above the knee. As these issues arise, a team of remote nurses coordinate care with other healthcare providers - preventing serious and costly episodes.

Our mission: Bring Joy to Healthcare. Join us if our cause inspires you!

We're looking for a Senior Product Engineer who operates as a true product partner. You'll own significant areas of our product, make architectural decisions, and influence what we build—not just how. A core pillar of this role is data and analytics: you'll own the infrastructure, models, and reporting that make Belle a genuinely KPI‑driven organization. You think in terms of patient and operational outcomes, weigh tradeoffs against business impact, and can push back on a spec when the data or the user need points elsewhere. You set the technical bar for the team and raise the people around you.

• Lead the design and delivery of major features across our Ruby on Rails web app and React Native mobile app
• Own data and analytics as a core part of the role—build and maintain the reporting, dashboards, and underlying data models the entire organization relies on to make decisions
• Partner with product and clinical leadership to shape roadmap and translate operational strategy into technical direction
• Own architecture and technical decisions for your areas; balance speed, scalability, and maintainability
• Set the standard for how the team uses AI coding tools to ship faster without sacrificing quality
• Mentor engineers through code review, pairing, and design discussion
• Identify high‑leverage opportunities in product, operations, and data—and drive them
• Help shape engineering practices, standards, and culture as we scale

• Our Community Health Worker mobile application that drives productivity, engagement, and data capture for our in‑field mobile workforce
• Our suite of scheduling and logistics tooling that drive workforce utilization and member engagement
• A custom CRM platform that enables our growth and retention marketing teams to power predictable, cost‑effective growth
• Clinical tooling to drive patient outcomes and utilization/efficacy of our clinical staff

• 5+ years of professional software engineering experience building and shipping production software
• Deep experience with React (or React Native) and Ruby on Rails—required
• Strong command of SQL and relational databases—you can model data well, write performant queries, and reason about schema design. Data and analytics are a core pillar of this role, and our engineers own them, not just features
• A track record of owning features or products end to end, including the product thinking behind them
• Comfort operating with incomplete information, making decisions without extensive process, and building systems that may support 10x growth over the next few years
• You're an early adopter and power user of AI coding tools (Claude Code, Codex, Cursor, etc.) and can show others how to get the most out of them
• Strong product judgment: you've influenced what gets built, killed bad ideas early, and measured impact after shipping
• A builder at heart—you make things on your own time because you can't help it (see concrete ask below)
• Experience mentoring engineers and elevating team standards
• Excellent communication across technical and non‑technical stakeholders

• Metabase or similar BI tooling—you'll likely be building in it regularly
• Inertia.js experience
• Healthcare, digital health, Medicare, or value‑based care experience
• Experience in fast‑paced, high‑growth, or startup environments

What does success in this role look like?

• Within your first 12 months, you will:
• Own a major product area
• Improve company‑wide reporting and analytics
• Mentor and support other engineers on our team
• Drive measurable improvements in operational KPIs through your product initiatives

• Competitive compensation based on experience
• Health, Dental, and Vision Insurance Benefits
• 401k
• PTO, Sick, Wellness leave, and Paid Holidays
• Opportunity for significant career growth and expansion of responsibilities
• Ability to reshape an industry and protect lives
