Are you excited by the idea of working at the cutting edge of 3D printing technology? Imagine being a key part of a team that is revolutionizing how we manufacture, all while working in an environment that champions autonomy, innovation, and accountability. If you have a passion for low-level firmware and a vision for how embedded OS should be, then this is more than just a job – it’s a journey that will put your talents to the ultimate test.At Supernova, we're not just innovators; we're game-changers. Weaim to produce end-use parts at scale and cost by developing a complete industrial solution to unlock the power and benefits of Additive Manufacturing. We are 100% customer-centered and aware that the value we are bringing is the ability to produce fully functional parts. We work with the conviction that excellence in science and engineering is the cornerstone of transformative change. In our relentless pursuit of excellence, we adopt a champion's mindset, we take controlled risks, and we are constantly on offense to get things done.Your MissionAs a Senior Firmware & OS Engineer at Supernova, your initial challenge will focus on low-level firmware implementation—driving development efforts related to MCU firmware for sensors, actuators, and real-time processes. From this strong foundation, you’ll also help shape the embedded architecture and industrial IoT strategy as we build towards a unified solution. In this role, you’ll take a hands-on approach to coding while setting a strategic vision for long-term scalability and seamless hardware integration. Your work will be central to the development of our advanced 3D printing systems, and you’ll collaborate closely with the electronics engineers to ensure the platform’s robustness and efficiency.Key ResponsibilitiesDevelop and implement low-level firmware to support sensors, actuators, and other real-time components.Select the technology stack for the industrial IoT platform, balancing immediate firmware needs with long-term embedded OS requirements.Lead the development of software architecture and operating systems for our 3D printing systems (from low-level MCU firmware to high-level OS).Define and implement communication protocols to connect MCU components with CPU components and cloud-based services.Collaborate closely with the electronics team to ensure integrated and efficient system functionality.Apply best practices in coding, testing, and maintenance to minimize technical debt.Contribute to team leadership and provide a vision for future-proofing software solutions.About YouBachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field.Minimum of 3 years of experience in developing MCU-level firmware, including implementation of sensors, actuators, real-time processes, communication protocols, and data acquisition.Relevant experience in embedded operating system development.
