Job description

Archer is an aerospace company based in San Jose, California building an all-electric vertical takeoff 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.

Our sights are set high and our problems are hard, and we believe that diversity in the workplace is what makes us smarter, drives better insights, and will ultimately lift us all to success. We are dedicated to cultivating an equitable and inclusive environment that embraces our differences, and supports and celebrates all of our team members.

What you’ll do:

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

General

• Excellent verbal and written interpersonal communication
