Technician, Engine Assembly

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 Technician, Engine Assembly is responsible for the high-accuracy assembly of Karno™ linear generator engine modules. This role supports scaling limited-production builds of a next-generation linear power generation platform.

Unlike traditional rotating engines, this role requires exceptional discipline in axial alignment, stack-up control, sealing integrity, and cleanliness, as well as close collaboration with engineering and quality during design maturation, testing, and iteration.

Duties and Responsibilities

Linear Engine & Genset Assembly

Assemble Karno™ linear engine subassemblies , including:

Reactor, Heater and Chillers

Seal systems (dynamic, static, high-temperature, and gas sealing)

Linear generator interfaces (stator/translator interfaces, housings)

Structural frames and alignment-critical assemblies

Perform axial and concentric alignment of linear components to tight tolerances.

Execute precision stack-up controlled assemblies where tolerance accumulation directly impacts efficiency and reliability.

Apply torque, preload, and fastening sequences per controlled build instructions.

Sealing, Cleanliness & Handling

Install and verify critical sealing interfaces supporting:

High-pressure, high-heat environments

Thermal cycling and dynamic motion

Maintain engine-grade cleanliness standards, including:

FOD prevention

Proper lubrication and material handling

Protection of sealing surfaces and linear bearing interfaces

Quality & Process Compliance

Follow detailed work instructions, engineering drawings, torque tables, and build travelers.

Perform in-process inspections and document critical characteristics.

Ensure part serialization and traceability for engine-critical components.

Identify, document, and escalate:

Fitment issues

Stack-up or alignment risks

Seal integrity or assembly-induced failure risks

Test, Teardown & Iteration Support

Support pre-test mechanical verification, leak checks, and readiness reviews.

Assist with post-test teardown, inspection, and failure analysis.

Rebuild and reconfigure engines based on test feedback and engineering changes.

Work closely with manufacturing and design engineers to refine assembly sequences and tooling.

Continuous Improvement & Scale-Up

Provide hands-on feedback to improve:

Assembly methods

Tooling and fixtures

Error-proofing and standard work

Support PFMEA actions, pilot build readiness, and transition toward limited production.

Participate in safety, quality, and lean manufacturing initiatives.

Additional duties and responsibilities as assigned, needed, or required for the business.

Qualifications

Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.

Qualifications include:

Education, Experience and Certifications

High school diploma or GED required

Technical certification, military technical training, or trade school preferred

3–7 years of precision mechanical assembly experience , ideally in:

Advanced engine or power systems

Aerospace or pressure systems

Prototype or pilot manufacturing environments

High-tolerance electromechanical assemblies

Experience with:

Seal installation and verification

Press fits and interference fits

Torque and preload-controlled fastening

Experience with free-piston, linear motors/generators, or non-rotating engine architectures preferred

Background in pressure vessels, combustion systems, or high-temperature assemblies preferred

Familiarity with prototype test cycles and teardown-driven learning preferred

Experience working under ISO 9001 / AS9100-style quality systems preferred

Exposure to electromechanical integration (mechanical + stator/translator interfaces) preferred

Skills and Abilities

Strong mechanical aptitude with emphasis on linear motion systems

Proficiency with precision measurement tools:

Micrometers, bore gauges, calipers, dial indicators

Feeler gauges and alignment tools

Ability to read and interpret engineering drawings, GD&T, and assembly schematics

Comfortable working with build documentation, travelers, and MES systems

Extreme attention to detail and precision

Discipline in controlled assembly processes

Strong mechanical intuition and problem-solving skills

Comfort working in evolving designs and pilot environments

Ownership of build quality and engine performance outcomes

Role Classification and Working Conditions

This is an hourly, non-exempt-level position. This position typically works in a production/assembly/engineering lab environment. Overtime may be required.

Physical/Other Requirements

Ability to lift and/or move up to 50 pounds.

Fine motor control and precision hand work for extended periods.

Ability to travel, as needed, by plane, automobile, etc.

We are not accepting candidates that require sponsorship for this role at this time.
