Together we are making instant access to physical goods through autonomous aerial robotics a reality. As our Senior Software Battery Engineer, you will report directly to our Aircraft Software Lead and play a significant role in our current and future battery system design and development. A passion for batteries and the potential they have is critical for this role as you will own a major subsystem that has huge implications for our system's overall capabilities.

You will:

  • Work with various cross-functional teams to develop requirements for a new Battery Management System (BMS) features, diagnostics, and algorithms
  • Design, implement, and test cutting-edge algorithms for run-time BMS logic to derive State-of-Charge, State-of-Health, State-of-Power and State-of-Energy computations.
  • Deliver high-quality C/C++ code for real-time embedded systems
  • Develop Software-in-the-Loop infrastructure in an object-oriented fashion, making a high degree of re-use of existing objects and objects that are highly reusable
  • Design a rapid test iteration framework for developers to use for quick, at-desk spot checks
  • Participate in hardware and software systems design reviews
  • Participate in hands-on hardware bring up, system debugging, and code optimization
  • Work in a dynamic, cross-functional team to advance our cutting-edge battery control and management strategy
  • Support power electronics hardware prototype design, verification, and validation
  • Develop safety-critical features like charge control, thermal control, fault detection, and diagnostics on multiple hardware platforms
  • Supports Quality, Reliability and Robustness efforts (DFMEA, Fault Tree analysis, etc)
  • Develop and enhance existing battery models to ensure Real vs. Simulation accuracy
  • Develop behavior models for various sub-components of the aircraft, complete with fault insertion capability engineering
  • Develop complex battery aging models which accurately reflect true cell aging patterns


  • 5+ years of relevant experience as a firmware engineer, embedded design, or software engineer in battery-related technologies
  • BS in Electrical Engineering, Computer Science, Computer Engineering or evidence of exceptional skills in related fields with practical software engineering experience
  • Experience with battery management systems and Lithium-ion batteries
  • Experience in robotics, real-time systems, embedded system, or autonomous vehicles
  • Deep knowledge of embedded programming platforms and engineering production firmware in C
  • Experience with microcontrollers, namely STM32
  • Experience with functional safety and embedded software development for safety-critical systems
  • Strong background in object-oriented design, prioritizing testability, reusability, and maintainability
  • Low-level driver development (e.g. CAN, SPI, I2C, ADC, PWM, TIBQ Chip from Texas instruments)
  • Participation in improving code robustness and designing testing infrastructure

Great additions:

  • Experience in reviewing schematic design and capture, in tools such as Altium Designer
  • Proficiency in C++ and/or other object-oriented programming languages

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.

Identifying yourself as an individual with a disability is voluntary, and we hope that you will choose to do so. Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past.
