What we're looking for:

We need a senior backend engineer with 5+ years of experience building production systems who has deep expertise in security, cryptography, and cloud infrastructure. You should be comfortable owning a platform end-to-end in a small, fast-moving team and have a track record of shipping secure, scalable backend services from scratch. Bonus points if you have experience with IoT, telematics, or fleet management systems where hardware communicates with cloud services.

What you'll do:

• Architect, develop, and maintain the complete Secure Fleet & Financing Management System - backend APIs, web application, and supporting infrastructure - from the ground up
• Design and implement secure authentication, authorization, and encryption mechanisms to protect sensitive vehicle and financing data
• Collaborate with embedded and electrical teams to integrate backend services with physical on-vehicle hardware (IoT/telematics)
• Define and operate cloud infrastructure, CI/CD pipelines, and deployment processes as the sole owner of the backend platform
• Integrate backend services with mobile and web-based tools for end users, internal administrators, and merchant/point-of-sale systems
• Provide technical leadership on architecture decisions, framework choices, and long-term platform strategy
• Establish best practices for code quality, testing, logging, and system observability as the platform scales
