Who is Re:Build Manufacturing? At Re:Build Manufacturing we're rebuilding America's manufacturing base and creating meaningful, sustainable jobs in areas that have been deindustrialized over the past 20-30 years. Our strategy is to employ technology, systems, deep financial resources, and best management practices to compete and win as manufacturers in the global market. We are NOT private equity. We do not buy companies with the intention of selling them. Over the next decades, we want to make a difference in the US manufacturing economy and the communities in which we operate. We believe in the power of people and the long-term competitive advantage that can be derived from helping our employees achieve their fullest potential. Who we are looking for A creative problem solver who can use engineering fundamentals to connect scientific theory with engineering design to create novel software solutions. While we value experience with specific tools (like C/C++, RTOS, or Linux), we care more about your ability to architect scalable systems and solve the 'impossible' problems that don't have a manual. A strong communicator who can describe technical solutions to colleagues and clients. A hands-on firmware engineer who likes to build breadboards, use software to debug hardware, and bring electromechanical systems to life. A technical multiplier who measures their own success by the growth and success of the engineers around them. A life-long learner who can take on a challenge in an unfamiliar field and quickly contribute to solutions. You are someone who is equally excited about mastering a new technology and then turning around to teach it to the rest of the team. Your curiosity drives you to stay ahead of industry trends, and your passion drives you to bring the team along with you. A collaborator that enjoys working in teams of scientists, electrical engineers, optical engineers, manufacturing partners, mechanical engineers, and industrial designers. What you get to do Develop embedded software for a wide range of products. These will include medical devices, robotics solutions, industrial automation products, consumer electronics, and much more. Learn across disciplines and acquire additional responsibilities over time. Interact directly with customers to learn about their needs, discuss our capabilities, and demonstrate our solutions. Work closely with electrical and mechanical engineers. Support hardware demonstrations with customers as needed. Become part of a diverse team of engineers that work hard, love what they do, and enjoy a great work-life balance. What you bring to the team Education: BS in computer science, electrical engineering, robotics, or related engineering disciplines. Experience: 8-12+ years of experience working as a firmware engineer on a variety of hardware platforms, using a diverse set of programming languages, and microcontrollers. Consulting: Experience working in a consulting capacity, having interfaced with internal and external clients. Communication & Collaboration : Excellent verbal and written communication skills with the ability to describe technical concepts to both peers and non-technical audiences. Electromechanical: Strong background in electromechanical systems requiring hardware/firmware interaction such as firmware control of actuators, motors, sensors, etc. Debugging: strong background in debugging hardware/firmware interaction using common lab tools such as logic analyzers, digital multimeters, and oscilloscopes. Micros & Interfaces: Working knowledge of microcontrollers and their common peripherals such as UART, SPI, I2C, USB, GPIO, ADC, PWM, etc. Programming Languages: Experience developing embedded software using C/C++ on custom embedded systems. Experience using scripting languages (Python, etc.) to control embedded hardware including ARM-based Linux (Raspberry Pi), basic microprocessors (Arduino), or integrated solutions like LabJack. Dev Tools: Experience using firmware development tools such as IDEs, compilers, debuggers, and cross-compilers. Good source-code management, including the use of source control (e.g. git), and good scheduling and issue management practice (e.g. Jira). Runtimes: RTOS: Experience with the implementation of real-time operating systems (FreeRTOS, Zephyr, others). Linux: A working knowledge of embedded Linux as well as writing drivers and applications. Bare Metal: Comfortable writing firmware to directly control hardware resources, without an operating system. Bonus skills: Implementation of control algorithms and an understanding of control theory. Working knowledge of common regulatory standards such as FCC emission requirements, UL safety standards. Understanding of medical device certification (ISO 13485, IEC 62304). The base salary range for this position is $143,666.72 – $215,500.08 per year.
