What They Are Looking For
Compensation
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.
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.
- 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
The base pay range for this role is $150,000 – $190,000 per year.
