Principal Electrical Engineer (Power Electronics)

Location: Austin, TX, US

Company

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

What you will do

• Design and specify power and voltage-conversion hardware, rectifiers, converters, and distribution devices for high-current, pulsed, or pulse-reverse reactor duty.
• Own panel integration, protection coordination, grounding and bonding, power quality, electrical safety, and code compliance for packaged modules.
• Relate electrical operating parameters to reactor performance, efficiency, and energy use across the real operating range.
• Mitigate thermal, EMI, and harmonic effects; partner with Mechanical and Controls teams on PLC integration and safe-state behavior.
• Build and run electrical FATs covering efficiency, thermal performance, harmonics, and fault conditions; diagnose failures and feed findings into design improvements.
• Drive design-for-manufacture, supplier qualification, manufacturing quality, commissioning support, electrical troubleshooting, reusable design standards, mentoring, and technical representation with customers and suppliers.

Requirements

• BS or MS in Electrical Engineering and 7+ years of power-electronics or power-supply design experience.
• Hands-on experience designing voltage-conversion devices, rectifiers, and converters through validated, manufacturable products.
• Experience with panel integration, protection, grounding, power quality, electrical safety, and compliance.
• Hardware bring-up and FAT experience covering efficiency, thermal, harmonics, and fault-condition testing.
• Design-for-manufacture and supplier-management experience with power components.
• Experience with CAD software such as AutoCAD Electrical, EPLAN, SolidWorks, or Fusion 360, and simulation tools such as COMSOL or ANSYS for system modeling and design optimization.
• Experience mitigating thermal, EMI, and harmonics at component, panel, and system levels.
• Exceptional written and verbal communication, including the ability to specify, review, and defend power-hardware designs to engineers, customers, and auditors.
• Comfort with ambiguity and the judgment to decide what to design and test next without waiting for direction.

Nice to have

• High-current DC and low-voltage AC or pulsed-power experience.
• Familiarity with UL, NSF, and field electrical codes, including NSF/ANSI 61 materials context for wetted or packaged hardware.
• Industrial water or process-plant deployment experience.
• PLC and drive integration literacy.
• Electrochemical or electrolyzer power-supply experience and knowledge of how waveform shapes affect electrode behavior.
• Thermal and electromagnetic simulation experience and electrical-design CAD experience.
• Reliability engineering and accelerated-life testing of power-related hardware.
• Knowledge of controls, instrumentation, automation, and SCADA or PLC systems.

Culture & Benefits

• Fast-paced environment focused on accelerating the development and adoption of water-treatment technologies.
• Work spans engineering, electrochemical, mechanical, controls, manufacturing, customer, partner, and supplier collaboration.
• Assessment tests are required as part of the recruitment process; candidates who do not complete them cannot progress to the next stage.
