Senior Software Engineer - #1163699

About the role

This is a founding-engineer role with real ownership. You will set the technical direction, govern the vendors building the platform, define the standards everyone integrates against, and progressively build the AI-native product layer on top. You will report directly to the founder.

Key responsibilities

• Review vendor codebases to map what exists, what is assumed, and where the systems need to connect
• Write and own the Integration Specification — the single source of truth for API contracts, event schemas, data naming, versioning, and error handling that both vendors follow
• Define a shared data model for entities that cross both systems — contracts, invoices, hirers, vehicles, and payments — with consistent fields, statuses, and tenant isolation
• Run a weekly vendor review: what was built, what drifted from spec, and what needs escalating — and hold the line on architecture
• Build the integration test suite that proves the two systems actually work together
• Build and ship the first end-to-end, human-plus-agent financial workflow
• Introduce automation and AI into the workflow progressively, where it genuinely adds value
• Design and deploy the first production AI agents
• Build out the intelligence layer on top of the financial engine
• Grow and lead the engineering team as the company scales

About you

• 5+ years building and shipping real software products — not just projects
• Experience designing or governing API integrations across multiple systems
• Experience technically directing or reviewing the work of an external dev team — and holding them to a standard
• Use AI tools natively in your own work and are meaningfully faster and better because of them
• Product mindset: ask why before how and change technical approach based on user problem understanding
• Write clearly and precisely
• Can design a relational data model for a complex domain that handles versioning, multi-tenancy, and audit requirements correctly from day one
