How much do fault detection diagnostics jobs pay per year?

As of Jun 11, 2026, the average yearly pay for fault detection diagnostics in the United States is $109,561.00, according to ZipRecruiter salary data. Most workers in this role earn between $80,500.00 and $138,500.00 per year, depending on experience, location, and employer.

What are the key skills and qualifications needed to thrive as a Fault Detection Diagnostics specialist, and why are they important?

To thrive in Fault Detection Diagnostics, you need expertise in control systems, HVAC or industrial equipment, and a background in engineering or a related technical field. Familiarity with building automation systems (BAS), analytics software, and industry certifications such as Certified Energy Manager (CEM) or relevant vendor certifications are highly valuable. Strong problem-solving abilities, attention to detail, and effective communication are essential soft skills for diagnosing issues and collaborating with teams. These skills ensure accurate detection and resolution of system faults, leading to improved operational efficiency and reduced downtime.

What are Fault Detection Diagnostics?

Fault Detection Diagnostics (FDD) refer to the use of software and analytical tools to automatically identify and diagnose faults or performance issues in systems such as HVAC, industrial equipment, or building automation systems. FDD processes data from sensors and control systems to detect abnormalities, pinpoint their causes, and sometimes suggest corrective actions. This helps organizations reduce downtime, improve efficiency, and prevent costly equipment failures. FDD is widely used in industries focused on maintaining operational reliability and energy efficiency.

What are some typical challenges faced by professionals in Fault Detection Diagnostics, and how can they be addressed?

Professionals in Fault Detection Diagnostics often encounter challenges such as managing large volumes of sensor data, distinguishing between false alarms and genuine issues, and keeping up with evolving building automation technologies. Collaborating closely with building engineers and IT staff is essential to accurately interpret diagnostic results and implement effective solutions. Continuous professional development and leveraging advanced analytics tools can help address these challenges and contribute to more reliable system performance.

What is the difference between Fault Detection Diagnostics vs HVAC Technician?

AspectFault Detection DiagnosticsHVAC Technician
CertificationsHVAC certifications, EPA refrigerant handlingHVAC certifications, EPA refrigerant handling
Work EnvironmentIndustrial, commercial, building automation systemsResidential, commercial HVAC systems
Industry UsageBuilding management, automation, energy efficiencyInstallation, maintenance, repair of HVAC systems

Fault Detection Diagnostics specialists focus on analyzing and identifying issues within building systems using advanced tools, often working in automation and energy management. HVAC Technicians perform hands-on installation, repair, and maintenance of heating, ventilation, and air conditioning systems. While both roles require similar certifications and may work in overlapping environments, Fault Detection Diagnostics emphasizes system analysis and troubleshooting, whereas HVAC Technicians focus on physical system servicing.

Job description

Job Title: Functional Systems Lead
Location: Burlingame, CA
Department: ESS Engineering
Reports to: CTO
Position Type: Full Time
About Peak Energy
Peak Energy is the first American venture to advance globally proven Sodium-Ion battery systems as the storage standard for the new era of renewable energy on a resilient grid. Sodium-Ion is cheap, readily available and safe, making it the leading contender in a rapidly evolving market.
Our leadership team is powered by decades of expertise in scaling gigawatt-level innovation at world-class companies such as Tesla, Northvolt, SunPower, Fluence, and Enovix. We are backed by strategic investment and product partners such as TDK Ventures and Eclipse Ventures.
About the Role - Functional Systems Lead:
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.
You will lead the definition of functional requirements, system behavior, and safety architecture, while partnering closely with embedded, hardware, and modeling teams-and may directly oversee embedded software development for safety-critical functions.
This is a highly cross-functional, hands-on leadership role ideal for someone who thrives in ambiguity and wants to shape both product and engineering direction.
What You'll Do (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

What You'll Bring (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
  • Experience driving cross-functional integration across hardware, software, and systems teams
  • 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
