• Work with embedded firmware, receivers, sensors, and hardware interfaces.
• Support data flow from physical receivers through processing systems, cloud services, APIs, and web applications.
• Develop backend services and customer-facing applications.
• Troubleshoot issues involving hardware integration, memory, concurrency, data processing, cloud services, and application performance.
• Collaborate on technical requirements, system architecture, and design decisions.
• Take ownership of projects from initial requirements through implementation and production support.

• Five or more years of professional software-engineering experience.
• Strong professional proficiency in C and/or C++.
• Experience developing web applications, backend services, frontend interfaces, or full-stack solutions.
• Experience with embedded systems, firmware, sensors, receivers, device interfaces, or hardware-software integration.
• Strong knowledge of data structures, algorithms, software design, memory management, and concurrency.
• Ability to debug complex problems across multiple technical layers.
• Experience with version control, testing, and code reviews.
• Strong communication, problem-solving, and independent project-ownership skills.

Preferred experience includes Google Cloud Platform, REST APIs, real-time operating systems, telemetry, networking, aviation, drones, aerospace, defense, IoT, robotics, or autonomous systems.

The company prefers a Syracuse-area candidate but will consider remote candidates anywhere in the United States. This person will become a foundational member of the US technical team and may grow into a broader technical leadership role.
