Senior Automation and Controls Engineer

Location: Austin, TX, US

Company

hirify.global develops electric-field water purification technologies, including the Farady Reactor, ALTEP, dissolved air flotation, and micro- and nano-bubble systems for municipal, commercial, residential, and consumer water applications.

What you will do

• Design and automate treatment modules, including layouts, piping, structures, skids or trailers, mechanical systems, hydraulics, and utilities.
• Create fabrication-ready packages with piping and instrumentation drawings, structural details, bills of material, and assembly documentation.
• Select and integrate flow, pressure, level, conductivity, pH/ORP, and other instrumentation; develop PLC/SCADA/HMI logic, I/O lists, control narratives, alarms, interlocks, safe states, and shutdown behavior.
• Build and maintain digital twins, validate models against bench, pilot, and field data, and use simulation to size and de-risk packages.
• Develop 3D CFD models using STAR-CCM+, Simcenter, or equivalent to guide hydraulic and thermal design.
• Support manufacturing, shop assembly, FAT, SAT, field commissioning, troubleshooting, root-cause analysis, SOP development, system maintenance, supplier coordination, and mentoring of junior engineers and designers.

Requirements

• BS or MS in Instrumentation, Controls, Mechanical Engineering, or a closely related field, with 5+ years of equipment or package-system design experience.
• Working knowledge of PLC, SCADA, HMI, instrumentation integration, and basic control logic.
• Track record of building digital twins or models, validating them against test or field data, and using them to guide design or operating decisions.
• Proficiency in CFD using STAR-CCM+, Simcenter, or an equivalent tool.
• Strong knowledge of Rockwell, ControlLogix, Iconics, Siemens, DeltaV, Allen Bradley, Wonderware InTouch, Zenon, and other comparable systems.
• DFM/DFA experience taking hardware from prototype to production.
• Field commissioning experience, including FAT and SAT.
• Programming skills in Python, MATLAB, or a similar language for data processing and model-to-data integration.
• Hands-on fluency with modern AI tools such as Claude or equivalent tools, strong written and verbal communication, and the ability to explain designs and model confidence to engineers, operators, and customers.
• Comfort with ambiguity and the judgment to decide what to design, model, and test next without waiting for direction.

Culture & Benefits

• Fast-paced environment focused on accelerating water-industry technology development and adoption.
• Opportunity to work across mechanical, electrical, process, manufacturing, supplier, and field-commissioning activities.

Hiring process

• Assessment tests are required as part of the recruitment process.
• Applications cannot progress to the next stage without completing the assessments.
