Electric Propulsion System Research Scientist, Amazon Prime Air

About the role

We are seeking a Research Scientist II to join our Electric Propulsion Subsystem team. In this role, you will be a significant and autonomous contributor, solving difficult engineering problems related to battery management systems (BMS) and energy storage. You will design, develop, and validate BMS hardware and algorithms from concept through production, working on high-voltage lithium-ion battery packs that push the boundaries of performance, safety, and energy density. This position requires an engineer who demonstrates strong technical depth in battery systems and BMS design while also exhibiting the system-level thinking and influence characteristic of our most impactful contributors. Location: USA, WA, Seattle.

Responsibilities

• Design, develop, and validate BMS architectures for high-voltage lithium-ion battery packs from concept through volume production, including cell monitoring and sensing strategy, communication topology, and isolation design
• Develop safety controls, fault detection and diagnostic mechanisms, cell balancing routines, and thermal protection boundaries, and lead test plans validating BMS designs against safety standards (e.g., UL 2271, IEC 62619, UN 38.3) for functional safety, thermal resilience, and abuse tolerance
• Develop software algorithms for State of Charge (SOC), State of Health (SOH), and State of Power (SOP) estimation using machine learning models
• Support Hardware-in-the-Loop (HIL) testing, bench verification, and real-world data analysis to validate BMS algorithms and correlate models with physical pack performance
• Design charging infrastructure interfaces, including charge profile management, communication protocols, and interoperability with external charging systems
• Apply system-level thinking to understand how the BMS integrates with and influences the broader product architecture, including power electronics, thermal management, and vehicle control systems, and maintain high-quality design documentation (schematics, algorithm specs, analysis reports, test results)

Qualifications

Basic Qualifications:

• Master's degree or Ph.D. degree in Electrical Engineering or related field
• 3+ years of developing electric propulsion and/or battery management systems.

Preferred Qualifications:

• Experience working on power systems hardware for aerospace programs (aircraft, drone, satellites, etc.)
• Experience leading vendor engagements and manufacturing partner discussions for power electronics and battery system.
• Working knowledge of DO-160 and DO-274 design and test standards and IP (Ingress Protection) rating requirements and design-for-environment principles
• Strong written and verbal communication skills
• Demonstrated ability to use AI tools to build mechanism that reduce routine work and bring processes to scale
• Demonstrated ability to learn new technical domains quickly and work independently on well-scoped tasks

Benefits

• Health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage)
• 401(k) matching
• Paid time off
• Parental leave

Pay

The base salary range for this position is $136,000.00 - $184,000.00 USD annually. Your Amazon package will include sign-on payments and restricted stock units (RSUs). Final compensation will be determined based on factors including experience, qualifications, and location.
