Senior Backend Developer

Role Description

• Push production AI agents into the platform's most complex flows. Build the MCP servers that orchestrate them: tool layer, context handling, model routing through OpenRouter.
• Build the integration layer that powers the platform and the AI agents on top of it: identity, e-signature, real-time data services. Every call has a user or an agent on the other end.
• Build the rules engines, configuration runtime, and AI Copilots that turn the platform into a product factory. Customers ship entirely new products without us touching the code.
• Bring whole companies onto the platform: importer pipelines, schema mapping, hard go-live dates. Every customer's data shape is different. Every cutover has a deadline that doesn't move.
• Engineer the multi-tenant infrastructure companies run on. Async workers, document pipelines, scheduled jobs touching every site. The AI agent fleet is joining them tenant by tenant.
• 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.

Qualifications

• Bachelor's Degree or higher in Computer Science or a related field.

• Professional experience working with Docker for containerization and AWS.
• Excellent verbal and written communication skills.
