Senior Full Stack Engineer (Ruby on Rails)

Opendate is the operating system for live music venues — booking, ticketing, marketing, and settlement, all in one place. We replace the tangle of spreadsheets, holds-and-confirms email chains, and ticketing platforms that independent venues, promoters, and festivals have been duct-taping together for decades. Customers range from 200-cap clubs to multi-day festivals. We're a Rails shop with real backend problems: multi-tenant ticketing at on-sale scale, financial settlements that have to reconcile to the penny, and integrations with the rest of the music industry's plumbing (Stripe, Dwolla, Seats.io, Twilio, SendGrid). If you like systems where correctness actually matters and the users are people you can go meet at a show, you'll fit in. Stack: Rails, React/Redux, PostgreSQL, Redis, BigQuery, AWS, GCP, Docker, Terraform. Flutter on mobile. AI-first engineering culture — Cursor, Claude Code, and Copilot are part of the daily workflow, not banned from it. 100% remote within the US (no sponsorship), with optional Indianapolis or Chicago offices if you want them. Looking for 5+ years of senior full-stack experience, comfortable owning projects end-to-end and shipping to production weekly. Apply: https://www.opendate.io/careers/senior-full-stack-software-e...
