Job description

Principal Engineer, Simulation Workbench

Concurrent Real-Time is part of HBK's Virtual Test Division, which focuses on providing real-time software, simulators, and hardware-in-the-loop solutions to virtually test products throughout the development cycle, helping companies accelerate innovation and reduce time-to-market, and improve their competitive advantage. With 250 highly skilled employees, HBK's Virtual Test Division has offices in Germany, Italy, France, UK, China, Japan, and the USA as well as a broad network of worldwide channel partners. Concurrent Real-Time is the industry's foremost provider of high-performance, real-time Linux software, hardware and professional services. Our mission is to be the leading provider of best-in-class real-time Linux solutions and support for time-critical applications, and to inspire technological advancements worldwide. For more than 50 years, we have been providing real-time solutions for mission-critical applications worldwide. With offices in 6 countries, our core competencies include:

• Real-time Linux and RTOS platforms engineered for deterministic, time-critical workloads
• X-in-the-Loop simulation: hardware-in-the-loop, man-in-the-loop, and AI-in-the-loop
• Custom engineered systems for aerospace and defense programs, from concept through fielded delivery
• High-speed data acquisition and signal conditioning
• High-performance visual systems and process control
• Low-latency signal processing

Concurrent Real-Time is currently seeking a full-time Principal Engineer for the Simulation Workbench team!

Must be a US citizen. Unable to hire dual citizens, green card holders or visa holders for this position.

About the Role

We are looking for a deeply experienced software engineer to serve as the technical lead for our Simulation Workbench (SimWB) team. SimWB is our real-time hardware-in-the-loop simulation platform, running on real-time Linux and driving a wide range of I/O hardware. As the most senior engineer on the team, you will work in the core of the product, including the real-time scheduler and configuration server, own significant subsystems end to end, and set the technical direction the rest of the team builds on. You will partner with the team's Manager on roadmap and architecture decisions. This is a hands-on senior individual contributor role with broad technical authority and no direct reports.

What You’ll Do

• Own and evolve core SimWB subsystems, including the real-time scheduler and the configuration server
• Design, implement, and debug I/O support for our own cards, including our FPGA cards, as well as for protocols such as EtherCAT, ARINC 429, MIL-STD-1553, CAN, and serial and Ethernet interfaces.
• Develop and maintain the SimWB SDK and API surfaces used by customers and by internal teams
• Diagnose and resolve complex real-time issues involving timing, determinism, and hardware/software integration
• Provide the deepest level of technical escalation support for customer issues, working with the Support and Applications Engineering teams
• Produce and maintain design documentation so that critical product knowledge is retained by the team
• Serve as the technical lead for the team: set coding and design standards, review designs and code, mentor Lead and Senior Engineers, and raise the technical bar of the group
• Partner with the SimWB Manager on roadmap and architecture decisions, and help assess the feasibility and effort behind proposed features
• Evaluate new technologies and translate future product needs into engineering feasibility

What We’re Looking For

• 10+ years of software development experience in a Linux environment
• Expert-level C and C++, with solid working knowledge of Java
• Demonstrated experience with real-time systems, including scheduling, determinism, and performance analysis
• Hands-on experience with I/O boards and device-level software, including reading hardware documentation and bringing up new boards
• Experience owning a significant subsystem or product area end to end
• Hands-on experience with MATLAB and Simulink, including integrating Simulink models into a real-time execution environment (highly preferred)
• Bachelor’s degree in Computer Science, Electrical Engineering, or equivalent experience

Nice to Have

• Experience with hardware-in-the-loop or man-in-the-loop simulation platforms
• Linux kernel or device driver development experience, including real-time kernel variants
• Experience with other third-party modeling and simulation tools such as Dymola, Adams, or rFpro, and with model exchange standards such as FMI/FMU
• FPGA exposure, or experience integrating FPGA-based I/O into software products
• Experience with Python and Java client or GUI development, including Swing or Qt
• Master’s degree in Computer Science or Electrical Engineering
