As of Aug 16, 2026, the average hourly pay for modbus in California is $24.12, according to ZipRecruiter salary data. Most workers in this role earn between $17.79 and $30.14 per hour, depending on experience, location, and employer.

What is the difference between Modbus vs PLC Technician?

AspectModbusPLC Technician
CredentialsKnowledge of communication protocols, certifications in industrial networkingCertifications in PLC programming, electrical or automation certifications
Work EnvironmentIndustrial settings, control systems, network troubleshootingManufacturing plants, automation systems, control panel maintenance
Industry UsageUsed for communication between devices in automation systemsDesign, install, troubleshoot PLC-based automation systems

While both roles operate within industrial automation, Modbus specialists focus on communication protocols between devices, whereas PLC Technicians handle programming and maintaining programmable logic controllers. Understanding both is essential for seamless automation system operation.

What are the key skills and qualifications needed to thrive as a Modbus engineer, and why are they important?

To thrive as a Modbus Engineer, you need a solid understanding of industrial automation, Modbus protocols (RTU/TCP), and electrical or control systems, usually backed by an engineering degree. Familiarity with PLC programming, SCADA systems, network troubleshooting tools, and relevant certifications such as Certified Automation Professional (CAP) is highly valuable. Strong problem-solving, attention to detail, and effective communication skills help in diagnosing issues and collaborating with multidisciplinary teams. These abilities are crucial for ensuring reliable, efficient integration and maintenance of Modbus-based systems in industrial environments.

What is a Modbus professional?

Modbus professionals are experts who understand and work with the Modbus communication protocol, which is widely used to connect electronic devices in industrial automation systems. They typically configure, troubleshoot, and maintain Modbus networks to ensure reliable data exchange between devices such as sensors, controllers, and SCADA systems. Their work is essential in industries like manufacturing, energy, and building automation, where seamless device communication is critical for operational efficiency.

What are some common challenges engineers face when integrating Modbus communication into industrial automation systems?

Engineers often encounter challenges such as ensuring compatibility between devices from different manufacturers, managing network latency, and troubleshooting communication errors like data loss or incorrect addressing. It’s also common to address issues related to protocol versions (Modbus RTU vs. Modbus TCP) and configuring the correct baud rate and parity settings. Collaborating closely with control system integrators and IT teams is essential to ensure seamless data flow and system reliability.

Senior Electrical Test / Systems Engineer

Archer

San Jose, CA • On-site

$126K - $158K/yr

Full-time

Re-posted 24 days ago

Job description

At Archer's Product Realization Lab, we build the high-power electromechanical infrastructure that makes flight possible. From megawatt-scale dynamometers to complex electrical test stands, we own the full stack: integration, software, and controls.

We are seeking a Senior Electrical (Test) Systems Engineer to serve as the ultimate authority on system health. This isn't a "follow the manual" role. You'll be operating at the volatile intersection of high-voltage power and sensitive low-voltage instrumentation-a boundary where noise, grounding issues, and transients create real-world consequences. We need a battle-tested expert who has seen these systems fail in industry and knows exactly how to build them to last.

What you'll do: 

  • Build and maintain real-time test and control applications on NI cRIO, PXI, and DAQ using LabVIEW, VeriStand, and Python, with strong CAN bus integration and test automation experience
  • Interface with subsystems via CAN bus, EtherCAT, Modbus, TCP/IP, and related industrial communication protocols, from initial bring-up through fault diagnosis in deployed systems
  • Diagnose and resolve electrical faults in medium- to high-power test systems including voltage/current ripple, transient noise, EMI, and grounding failures, with full ownership of root-cause findings and mitigation recommendations
  • Lead grounding architecture reviews and remediation across the lab, with specific focus on how high-voltage ground faults cascade into low-voltage instrumentation systems
  • Set up and operate oscilloscopes, signal conditioning hardware, and bench instrumentation to characterize and isolate electrical anomalies in complex, integrated test environments
  • Own ongoing support of delivered test systems including software updates, bug fixes, new feature integration, and in-field troubleshooting to ensure systems remain reliable as configurations evolve
  • Support system bring-up, integration verification, and validation across hardware, controls, and software layers

What you need:

  • Degree in Electrical Engineering or equivalent hands-on industry experience
  • Proven LabVIEW development on cRIO and PXI platforms - building and maintaining real-time applications, not just configuring existing ones
  • Hands-on experience with CAN bus, EtherCAT, Modbus, and TCP/IP in deployed, real-world systems
  • Python proficiency for test automation, data analysis, and tooling
  • Electrical background with hands-on grounding architecture, oscilloscope-based fault diagnosis, and signal conditioning in mixed high/low voltage environments
  • Experience with version control (Git) and structured software development practices

Bonus Qualifications:

  • NI Certified LabVIEW Developer (CLD) or Architect (CLA)
  • Experience in aerospace, EV powertrain, motor drive, or power electronics test environments
  • HIL or real-time validation experience (NI, dSPACE, Speedgoat, or equivalent)
  • Familiarity with NI SystemLink, DIAdem, or TestStand
  • Additional protocols: EtherNet/IP, LIN, RS-232/485
  • Electrical CAD tools (EPLAN, AutoCAD Electrical)

Please note that this job description is intended to provide a general overview of the position and does not include an exhaustive list of responsibilities and qualifications.

At Archer we aim to attract, retain, and motivate talent that possess the skills and leadership necessary to grow our business. We drive a pay-for-performance culture and reward performance that supports the Company's business strategy. For this position we are targeting a base pay between $126,700 - $158,400. Actual compensation offered will be determined by factors such as job-related knowledge, skills, and experience.

Archer is committed to provide a safe workplace and a safe aircraft. This is a safety sensitive designated role. Employment in safety sensitive positions is contingent on successful passage of a background check and is subject to pre-employment and random drug screening.
