Full-time

About the Company

A profitable, fast-growing SaaS platform in the mission-driven technology space, backed by a leading accelerator and a recent $140M growth investment. The company facilitates hundreds of millions in transactions annually and is on track to cross $100B in total volume over the next decade. With 130+ employees distributed across 30+ states and a $100M AI product investment underway, this is a company operating at meaningful scale with significant runway ahead.

• Remote-first role based in the US. Team members are expected to attend multiple company-wide and team-specific on-sites throughout the year.
• Contract to Hire after 3 months.
• Sponsorship not available.

The Role

This is not a traditional product engineering role. It is a deeply business-embedded engineering position at the intersection of Finance, Engineering, and Operations. The hire will build the systems and instrumentation that make unit economics visible, trustworthy, and actionable - working in close partnership with Finance, Operations, and Engineering leadership rather than from a standard product roadmap.

Ideal for a Rails engineer who wants to apply strong technical skills to real operational problems and who is motivated by business impact, not just feature delivery.

Responsibilities

• Own full-stack delivery from UI to backend services, including database tuning and performance
• Build new features start to finish - architecture design, coding, automated testing, and production support
• Work closely with teammates in a fast-paced, agile environment across pods and the broader Engineering org
• Tackle technical issues throughout the stack and contribute to shared documentation
• Contribute to coding standards, tech debt refinement, and system security monitoring
• Participate in interviewing and onboarding new team members
• Participate in on-call support rotation (team-based, paired)

What They Are Looking For

• Strong experience with Ruby on Rails
• System design experience focused on incremental, scalable, resilient architecture
• Comfortable across the stack - backend services, databases, and light frontend
• Experience with modern frontend frameworks (React, Vue.js)
• SQL database experience (PostgreSQL, MySQL, SQLite)
• Deployment experience on Heroku, AWS, or similar
• 5+ years of hands-on development experience
• Comfort with financial concepts: margins, COGS, pricing, revenue recognition, or unit economics
• Experience building systems where correctness, auditability, and explainability matter
• Ability to work with non-technical stakeholders and translate ambiguous business questions into concrete technical work
• Comfortable with ambiguity - shaping the problem, not just executing against a spec

Bonus

• Deep Ruby on Rails and RSpec expertise
• Postgres database administration experience
• Shipped code supporting tens of thousands of users including enterprise customers
• Operations/SRE experience including networking, caching, database, and performance triage
• Experience in fundraising, crowdfunding, fintech, or payments products
• Startup environment experience
• Experience building internal tools for Finance or Operations teams

Compensation

The base pay range for this role is $150,000 – $190,000 per year.
