Junior Controls Engineer

Junior Controls EngineerRole summaryThe Junior Controls Engineer joins the ADC Hardware sub-team and reports to the Hardware Lead.You will help design, document, build, and commission the physical controls layer for propellantmanufacturing equipment: control panels, field wiring, sensors, VFDs, and industrial networks. Youwill work closely with the Software sub-team, which owns PLC programs and HMIs, and withTechnicians who install and maintain equipment on the floor. This is a hands-on, early-career rolewith direct mentorship from senior controls engineers.Responsibilities• Create and maintain electrical schematics, panel layouts, wiring diagrams, and I/O lists for new andexisting equipment• Specify and select components including sensors, transmitters, load cells, valves, motor starters,VFDs, power supplies, and remote I/O• Support panel builds, field wiring, and installation alongside the Technicians sub-team• Commission new equipment through I/O checkout, loop checks, sensor calibration, and VFDparameter setup• Configure and troubleshoot industrial networks and devices using Modbus TCP, EtherNet/IP, andOPC UA• Integrate instrumentation with data acquisition hardware such as NI cRIO and cDAQ• Partner with the Software sub-team to define I/O mappings and validate PLC and HMI behavioragainst the hardware• Diagnose and resolve electrical and controls issues on the production floor, including occasionaloff-hours support during runs• Keep drawings, bills of materials, and documentation current in our revision-controlled libraries• Follow and help improve electrical safety, lockout/tagout, and hazardous-location practices for anenergetics environmentRequired qualifications• BS in Electrical Engineering, Mechatronics, Mechanical Engineering, or a related field, orequivalent hands-on experience• 0 to 2 years of experience in industrial controls, automation, or electrical design (internships,co-ops, and competition teams count)• Ability to read and create electrical schematics and wiring diagrams• Working knowledge of AC and DC power distribution, 24 VDC control circuits, and analog anddiscrete I/O• Familiarity with PLC fundamentals and ladder logic• Comfort with hand tools, multimeters, and hands-on work in a manufacturing environment• Clear written and verbal communication• Must be a U.S. person as defined by ITARPreferred qualifications• Experience with an electrical CAD tool such as AutoCAD Electrical, EPLAN, or SolidWorksElectrical• Exposure to industrial protocols such as Modbus TCP, EtherNet/IP, CIP, or OPC UA• Hands-on experience with VFDs, servo systems, or motor control• Familiarity with WAGO, Allen-Bradley, or similar PLC and remote I/O platforms• Experience with NI hardware (cRIO, cDAQ) or LabVIEW• Knowledge of NFPA 70, NFPA 70E, NFPA 79, or UL 508A• Exposure to hazardous-location equipment, intrinsic safety, or energetics manufacturing• Basic scripting in Python for testing, data review, or device configuration• Experience in defense, aerospace, or another regulated manufacturing environmentWork environment and requirements• Location: on site at our Luling, TX facility, with occasional travel to Socorro, NM (open question:confirm primary site and any Austin office time)• Split between office work and the production floor, including work around energetic materials understrict safety procedures• Ability to lift up to 50 lb, climb ladders, and work in panels and on equipment for extended periods• Willingness to wear required PPE and follow site safety, LOTO, and ESD procedures• Occasional evening or weekend support during production runs and commissioning• Ability to obtain and maintain a U.S. security clearance may be required (
