About the company

Series A, YC-backed fintech building the AI financial-ops platform for construction, a $12T industry still running on decades-old, often on-prem software with no APIs. 500+ paying customers and growing fast.

The role: Software Engineer

For engineers who love simplifying complex systems, unifying fragmented data and building high-scale backends. Every integration is different: part engineering, part archaeology.

• Unification: bring dozens of fragmented systems under one standard (data models, auth, account linking, filters, pagination)
• On-prem: connect to SQL-, DLL- and API-based systems built 20-40 years ago and add real-time communication and webhooks where none exist
• Scale and speed: millions of API requests a day, caching and storage layers, shipping code daily
• Operational excellence: a reliable, SLA-backed API layer with testing across 1k+ endpoints
• Front end too: build apps that dog-food the API

What they're looking for

• 1-5 years as a back-end or full-stack engineer who can work independently
• Undergrad CS degree
• Recent Seed-Series D startup experience, or a clear desire to join a startup
• Familiarity with AWS
• Self-motivated, high ownership, low ego

Tech: PostgreSQL, Redis, AWS

Compensation: $140K-$285K base + 0.05-0.25% equity + 15% annual bonus

Location: In person in San Francisco, 5 days/week. Visa sponsorship and relocation bonus available.

Benefits: 90% of healthcare covered, 100% 401k match up to 4%, on-site gym, commuter benefits, breakfast and dinner stipends
