Engineer, Test & Validation

The posting, as Hyliion wrote it

Hyliion is committed to creating innovative solutions that enable clean, flexible and affordable electricity production. The Company’s primary focus is to develop distributed power generators that can operate on various fuel sources to future-proof against an ever-changing energy economy.

Job Purpose

The Engineer, Test & Validation is responsible for converting engineering and customer objectives into measured and validated results on the KARNO development team. The role covers the full test cycle: defining the test, assembling and instrumenting the hardware, executing the run, reducing the data, and presenting conclusions in technical review. Work spans KARNO Power Modules and Cores, linear generator and motor dynamometers, and component and subsystem rigs, and the resulting data directly informs program decisions. Because KARNO departs from conventional reciprocating and turbine architectures, using flameless oxidation to drive sealed helium through a thermodynamic cycle with a single magnet-carrying piston per shaft on pressurized helium bearings generating native 800 VDC, no established test methodology exists for a machine of this type. This position therefore carries significant influence over the test methods, rigs, and acceptance criteria against which KARNO is validated.

Duties and Responsibilities

• Operate KARNO Power Modules and Cores through startup, steady-state, step-load, load-acceptance and load-rejection, endurance, thermal cycling, and fuel-switching sequences, evaluated against defined acceptance criteria including ISO 8528 performance classes and program-specific targets.
• Operate and maintain linear generator and motor dynamometers, resistive and reactive load banks, and the associated power measurement chain, characterizing efficiency, force, thermal limits, and controls behavior across the operating envelope.
• Commission and operate regenerator, heat exchanger, burner, seal, bearing, and pressure vessel rigs, covering flow, pressure drop, effectiveness, leak rate, durability, and life testing on the components that set KARNO's performance.
• Perform mechanical assembly of test articles and rigs, including instrumentation installation and routing, harness build, gas and coolant plumbing, sensor calibration, channel checkout, and rig commissioning.
• Design, procure, and fabricate fixtures, adapters, brackets, ducting, and tooling where no suitable off-the-shelf solution exists, including CAD models, drawings, and as-built documentation.
• Translate engineering objectives into test plans, DVP&R entries, test matrices, instrumentation lists, run sheets, and acceptance criteria, including the hazard analysis required to release a test for execution.
• Configure data

• Disciplined approach to safety that identifies hazards, engineers them out, and keeps testing on schedule.
• Rigorous about data quality, able to distinguish a genuine signal from an instrumentation problem and resolve it before it reaches a report.
• Self-directed in identifying the next test to run, building it, and executing it.
• Ability to collaborate across mechanical, electrical, controls, software, and manufacturing disciplines.
• Ability to treat failed test results as data and apply them to subsequent design and test iterations.
