Software Engineer, BMS

Archer is an aerospace company based in San Jose, California building an all‑electric vertical take‑off and landing aircraft with a mission to advance the benefits of sustainable air mobility. We are designing, manufacturing, and operating an all‑electric aircraft that can carry four passengers while producing minimal noise. We believe that diversity in the workplace makes us smarter, drives better insights, and ultimately lifts us all to success.

• Embedded development and verification of safety critical software components for the aircraft battery management system
• Develop and integrate battery controls and complex low‑level drivers for battery microcontrollers to interface directly with analog and digital front‑end circuitry
• Work with systems engineers to decompose item requirements into high‑level and low‑level software requirements in compliance with DO‑178C
• Work with a multi‑disciplinary team to develop, integrate, verify and certify complex hardware/software systems
• Develop and implement fault detection and diagnostic algorithms in software to identify and respond to hardware‑level events such as insulation breakdown, short circuits, and sensor failures
• Apply digital signal processing and filtering techniques to sensor data (e.g., cell voltages, pack current) to improve the accuracy and reliability of critical state estimation and protection functions
• Analyze hardware schematics to inform the development of low‑level software and lead the initial board bring‑up and debugging of new BMS hardware designs
• Participate in the definition and documentation of streamlined software development and verification processes supporting the certification of safety critical software to comply with DO‑178C
• Foster team collaboration to promote and support personal development

• Excellent verbal and written interpersonal communication
• Excellent organizational skills
• Collaborative mindset
• Passion for learning and problem solving

• 10+ years of experience in a related field
• At least a BS in Electrical Engineering, Computer Engineering, Computer Science, or related degree
• Proficiency with C/C++
• Familiarity with safety critical software development standards (DO‑178C, ISO 26262, ASIL) to high criticality levels (DAL‑A/B or ASIL C/D)
• Hands‑on experience through the Full Software Development Life Cycle (development through verification and/or certification/production)
• Hands‑on understanding of low‑level communication standards and protocols (RS‑422/485, CAN, ARINC‑429, AFDX, Ethernet, TCP/IP, SPI, I2C, etc.) and their hardware implementation
• Working knowledge of sensor technologies and measurement techniques for high‑voltage battery systems (current sensing, voltage monitoring, temperature measurement)
• Familiarity with diverse tools and technologies used for the development, testing and analysis
• Experience working on Battery Management Systems
• Excellent organizational and communication skills

• Experience with MATLAB/Simulink
• Experience with modeling tools/certification (DO‑331)
• Familiarity with modeling tools like UML or SysML
• Working with Real Time Operating Systems (RTOS)
• Demonstrated experience with initial board bring‑up, hardware debugging, and using lab equipment (oscilloscopes, logic analyzers, power supplies)
• Experience with the HW in the Loop, SW in the Loop or MIL
