• Collaborate with hardware, QA, product management, and other cross-functional teams to define requirements and deliver high-quality releases.
• Apply Agile methodologies to manage project work, prioritize deliverables, and continuously provide value.
• Review customer standards and technical specifications to derive clear, actionable software requirements for new product development.
• Identify, troubleshoot, and resolve complex technical issues across development, testing, production, and field environments.
• Participate in peer code reviews and drive ongoing improvements to engineering processes, tools, and best practices.
• Create and maintain clear technical documentation, including software design specifications, installation instructions, and engineering guidelines.
• Assess project scope, technical risk, and resource needs for complex software modules; advise on design strategies and product enhancements.
• Mentor junior engineers through technical guidance, design feedback, code reviews, and collaborative problem-solving.
• Champion the practical integration of AI tools and workflows to improve engineering efficiency and productivity.
• Travel up to 10% for field troubleshooting, data collection, site surveys, and customer support activities in the United States and internationally.

Required Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, Computer Engineering, or a related technical field; a Master’s degree is a plus.
• 5+ years of professional software development experience, including at least 3 years of production C++ development.
• Extensive experience developing, debugging, and optimizing C++ applications in performance-critical or resource-constrained environments.
• Demonstrated expertise in software architecture and designing robust, scalable, maintainable, and testable solutions for industrial, automation, robotics, manufacturing, or embedded systems.
• Hands-on experience developing low-latency, real-time software for embedded Linux environments.
• Strong experience with multithreaded programming, inter-process communication, and system-level debugging.
• Deep knowledge of zero-trust networking over TLS, including certificate and chain-of-trust management.
• Strong understanding of cybersecurity principles for IoT and embedded systems, including TPM2 secret storage, secure boot, signed over-the-air updates, operating-system hardening, and device management.
• Experience designing and implementing integration tests involving hardware-in-the-loop environments.
• Advanced understanding of code testability, automated testing practices, and CI/CD pipelines.
• Proficiency with Git version control.
• Ability to work with hardware interfaces and troubleshoot complex software-hardware integration issues.
• Strong verbal and written communication skills, with the ability to collaborate effectively across engineering, QA, product, and customer-facing teams.
• Excellent analytical and problem-solving skills, with a demonstrated ability to work independently and within cross-functional teams.

Preferred Qualifications

• Familiarity with industrial communication protocols such as Modbus, CAN bus, and OPC UA.
• Experience with Go, Python, shell scripting, or related automation tools.
• Experience supporting field deployments, collecting diagnostic data, or troubleshooting customer systems.
• Experience working in regulated, safety-conscious, or cybersecurity-focused product environments.
