We build payment and point-of-sale software for restaurants, bars, and nightclubs, mostly on Oracle MICROS Simphony (we're an Oracle partner). Small team, real money moving in production — you own systems, not tickets.
Stack: Go (Echo, GORM, Postgres) for the payments API and the Oracle SPI/OPI service; Next.js / React / TypeScript for the operator portal; Kotlin / Jetpack Compose for the Android card-terminal app.
Looking for ~3–6 yrs, strong in Go or TypeScript and happy to learn the rest. You care about correctness (a double-charge isn't a cosmetic bug) and can read an existing codebase. Payments/Simphony experience is a plus, but we'll teach it.
