About the Role

The Product Engineer – Software is a hands-on builder who owns execution across SprintRay’s connected software ecosystem. This role sits at the intersection of embedded systems, cloud infrastructure, AI-driven features, and APIs, with a strong emphasis on shipping reliable, real-world software that powers physical devices.

You’ll combine solid engineering fundamentals with strong product intuition—balancing speed and pragmatism while making thoughtful tradeoffs between technical constraints, customer experience, and long-term platform health. This is a highly collaborative role that works closely with firmware, hardware, manufacturing, and product teams to turn ideas into production-ready software.

• Leverage telemetry and device data to identify failures, improve diagnostics, and increase uptime and reliability.

• Translate customer issues, field data, and operational insights into clear, actionable software requirements.

• Prototype, iterate, and ship AI-enabled and data-driven features that enhance the user experience.

• Challenge legacy approaches thoughtfully and help push the platform toward a modern, scalable IoT architecture.

• Contribute to technical decisions with a strong sense of product quality, usability, and maintainability.

Required Qualifications

• Education: Industrial Engineer, Systems Engineer or other relevant engineering fields

• 5+ years of experience building software for connected or electromechanical systems, such as embedded software, IoT devices, robotics, drones, smart home products, or similar.

• Comfortable working across the stack and at the boundaries of firmware, hardware, cloud services, and mobile or web applications.

• Strong intuition for telemetry, diagnostics, and how devices behave—and fail—in real-world environments.

• Solid engineering fundamentals with the ability to write clean, reliable, and maintainable code.

• Product-minded: able to balance technical constraints with customer needs and business goals.
