HILSIL Software Design Lead

YOUR MISSION 

True Anomaly is looking for you, a creative and experienced engineer, to develop a custom software for the hardware-in-the-loop / software-in-the-loop (HIL/SIL) testbed for our spacecraft. In this role, you’ll be responsible for verifying the spacecraft-level functionality and supporting on-orbit anomaly resolution. You’ll take full ownership of the development, configuration control, and maintenance of the HIL/SIL software. Bring your innovative ideas for a "factory of the future" and apply them in a fast-paced production environment with same-year space flight results. 

RESPONSIBILITIES 

• Lead the software design, development, and implementation of Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) systems for spacecraft testing and validation. 

• Define the architecture for HIL/SIL systems to enable accurate simulation of spacecraft dynamics, sensors, actuators, and environment. 

• Collaborate with systems engineering, GNC, avionics, and software teams to define requirements and ensure seamless integration of HIL/SIL systems into the development lifecycle. 

• Develop high-fidelity real-time simulation models of spacecraft subsystems, including propulsion, thermal, power, and communication systems. 

• Implement and integrate simulation interfaces, data acquisition systems, and real-time control hardware to create a comprehensive HIL/SIL testing platform. 

• Design and execute test campaigns using HIL/SIL systems to validate software, firmware, and hardware functionality before integration and flight. 

• Analyze and troubleshoot issues identified during HIL/SIL testing, collaborating with engineering teams to resolve them efficiently. 

• Maintain and upgrade HIL/SIL systems to support evolving mission requirements and technology advancements. 

• Define, lead, execute test and flight scripts used in ground testing and flight. 

QUALIFICATIONS 

• Bachelor’s degree in software, electrical, aerospace, or controls engineering. 

• 5-7+ years of professional experience with spacecraft simulators and EGSE.  

• Demonstrated excellence software systems and integration with hardware. 

• Experience with CAD, ability to open models, review drawings.

• Familiarity with communication protocols, including CAN, SPI, UART, and Ethernet, as applied in HIL/SIL setups. 

• Demonstrated proficiency in Python, C++ and C#. 

• Demonstrated proficiency programming for Beckhoff Automation IPCs in C#/Visual Studio, National Instruments LabVIEW, or Dspace.

• Ability to implement systems that incorporate software version control such as Github.

• Demonstrated ability to work autonomously with little input on requirements or management oversight.

• Excellent written and verbal communication skills.

PREFERRED QUALIFICATIONS 

• Experience with spacecraft-specific HIL/SIL challenges, such as GNC system validation, fault-tolerant design testing, and closed-loop control verification. 

• Proven track record of innovation in test automation, simulation fidelity, or integration efficiency. 

• Experience working in a fast-paced, startup environment or a similarly dynamic setting. 

COMPENSATION 

• California Base Salary: $145,000-$200,000 

• Equity + Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave 

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job related knowledge and skills, education, location and experience. 

ADDITIONAL REQUIREMENTS 

• Ability to maintain or obtain TS//SCI clearance 

• Work Location: LB or Centennial 

• Work environment is in a standard office, working at a desk or in a production factory. 

• Physical demands may include frequent standing, sitting, walking, bending, and lifting or carrying items up to 20lbs.
