Staff Software Engineer (Backend-Focused)

What They Do

Our client is a Series A startup, building the modern operating system for the hospitality industry: a two-sided marketplace + automated accounts payable + bill-pay platform. They are already live with dozens of groups and thousands of suppliers, digitizing millions in paper invoices every month and moving real dollars through the platform.

The role

They are looking for a backend-focused staff-level engineer who will own major product surface area end-to-end (especially payments and money-movement) and bring professional rigor as they scale from 1-to-N. You’ll work directly with the founders and a small, high-ownership team.

You’ll be responsible for:

• Designing and shipping core payments and money-movement features (ACH, virtual cards, bank integrations, compliance flows)
• Building and scaling rock-solid integrations with banks, accounting platforms, ERPs, payroll systems, and property management systems
• Professionalizing the Rails monolith and infrastructure for high-volume financial data while still moving extremely fast

About you:

• 8–12+ years shipping production systems at staff/expert level
• Deep, current Ruby on Rails expertise (monolith, Postgres, Sidekiq, etc.)
• Strong backend ownership with comfort scaling distributed systems (caching, data consistency, microservices extraction, high-throughput pipelines)
• Real payments/fintech experience (PCI, ACH, bank APIs, accounting integrations, compliance workflows)

Compensation & perks

• $160K–$230K base + meaningful Series A equity (real upside)
• 75% paid medical, dental, vision for you + dependents
• 401(k)
• Quarterly team offsites (they fly everyone in and put the team up at partner hotels)
• Remote-first, minimal meetings, high-trust culture
