Senior Python Backend Engineer, Financial Systems

Responsibilities

• Push production AI agents into the platform’s most complex flows, and build the Python services and MCP servers that orchestrate them: tool layer, context handling, model routing through OpenRouter
• Build the integration backbone the platform runs on: payments, identity, e-signature, real time data, at the latency live decisions demand
• Build out the rules engines and configuration runtime that turn the platform into a product factory, with customers shipping entirely new products on top of us without us touching the code
• Migrate whole companies onto the platform: importer pipelines, batch reconciliation services, zero data loss
• Build and scale the multi-tenant batch systems that move real money every night: settlement runs, document pipelines, async workers, where every customer’s data has to stay correct under load
• Design the public APIs the entire customer ecosystem runs on, with AI agents as first-class consumers and the contracts that let new endpoints ship at speed
• Build the financial systems behind every dollar that moves through the platform: billing, payouts, commissions, refunds, every cycle
