The Role
We're looking for a mid-level Ruby developer to join our engineering team and help build and maintain the software that powers elections. You'll be working on real, meaningful problems, complex data workflows, client-facing tooling, and backend systems that have to work flawlessly when it counts most. You'll collaborate closely with cross-functional teammates and have real ownership of your work from day one.
This is a hybrid role, three days a week in our St. Louis office, two days remote. We genuinely like each other here, so the in-office days don't feel like a punishment.

- 3-5 years of professional Ruby on Rails experience
- Solid understanding of RESTful API design and implementation
- Comfortable with relational databases (PostgreSQL preferred) and writing efficient queries
- Familiar with Git and collaborative development workflows
- Experience with test-driven development (RSpec, Minitest, or similar)
- Strong communication skills, you can explain what you're building and why
- Self-directed and comfortable asking for help when you need it
- Genuinely curious about how things work and how to make them better
