Functional Systems Lead

About the role

Peak Energy is seeking a Functional Systems Lead to own system-level architecture, requirements, and integration across embedded software, electrical systems, and controls for our energy storage products. This role sits at the intersection of embedded systems, electrical engineering, and system modeling, ensuring our products are safe, reliable, and performant from cell to grid.

Responsibilities

• Own system-level architecture and functional definition for energy storage systems (BMS, controls, protections, EMS integration)
• Define and manage system requirements, interfaces, and traceability from cell → module → pack → system → grid
• Lead functional safety architecture, including fault detection, diagnostics, and protection strategies
• Drive systems integration across embedded software, power electronics, thermal, and mechanical subsystems
• Partner with embedded teams to guide development of real-time, safety-critical firmware (controls, protections, communication)
• Develop and validate system models (performance, thermal, electrical behavior, fault conditions) to inform design decisions
• Lead verification & validation strategy (DV/PV), including test definition, coverage, and requirements validation
• Support certification efforts (UL, IEC, IEEE), ensuring compliance at the system level
• Identify system risks and drive DFMEA, fault analysis, and mitigation strategies
• Build and mentor a high-performing systems/embedded team, setting clear ownership and technical direction

Qualifications

• 10+ years of experience in systems engineering, embedded systems, or electrical engineering, with 3–5+ years in technical leadership
• Strong background in safety-critical systems (battery systems, automotive, aerospace, industrial, or similar)
• Experience defining and managing system requirements, interfaces, and architecture
• Deep understanding of embedded systems and real-time controls
• Familiarity with electrical systems (power electronics, battery systems, sensing, protections)
• Experience with system modeling and simulation (MATLAB/Simulink, Python, or similar)
• Strong experience with DFMEA, fault handling, and system reliability engineering
• Excellent communication skills and ability to operate across multiple technical domains
• Bachelor’s, Master’s, or PhD in Electrical Engineering, Mechanical Engineering, Computer Engineering, or related field

Preferred Qualifications

• Experience with battery management systems (BMS) or energy storage systems
• Background in functional safety standards (ISO 26262, IEC 61508, UL 9540, etc.)
• Experience leading or mentoring embedded software teams
• Familiarity with grid-scale energy systems, EMS, or power systems integration
• Experience in startup or high-growth environments

Benefits

Our competitive benefits package includes:

• Flexible time off
• Comprehensive medical, dental, and vision coverage
• Strong 401(k) plan
• Equity opportunities
• Many great work perks

Compensation

The salary range for this role is $150,000-$225,000, with actual pay varying based on work location, experience, and skills.
