Technician, Engine Assembly

Hyliion is committed to creating innovative solutions that enable clean,flexible and affordable electricity production. TheCompany's primary focus is to develop distributedpower generators that can operate on various fuelsources to future-proof against an ever-changingenergy economy.Job PurposeThe 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 ResponsibilitiesLinear Engine & Genset AssemblyAssemble Karno linear engine subassemblies, including:Reactor, Heater and ChillersSeal systems (dynamic, static, high-temperature, and gas sealing)Linear generator interfaces (stator/translator interfaces, housings)Structural frames and alignment-critical assembliesPerform 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 & HandlingInstall and verify critical sealing interfaces supporting:High-pressure, high-heat environmentsThermal cycling and dynamic motionMaintain engine-grade cleanliness standards, including:FOD preventionProper lubrication and material handlingProtection of sealing surfaces and linear bearing interfacesQuality & Process ComplianceFollow 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 issuesStack-up or alignment risksSeal integrity or assembly-induced failure risksTest, Teardown & Iteration SupportSupport 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-UpProvide hands-on feedback to improve:Assembly methodsTooling and fixturesError-proofing and standard workSupport 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.QualificationsReasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.Qualifications include:Education, Experience and CertificationsHigh school diploma or GED requiredTechnical certification, military technical training, or trade school preferred3-7 years of precision mechanical assembly experience, ideally in:Advanced engine or power systemsAerospace or pressure systemsPrototype or pilot manufacturing environmentsHigh-tolerance electromechanical assembliesExperience with:Seal installation and verificationPress fits and interference fitsTorque and preload-controlled fasteningExperience with free-piston, linear motors/generators, or non-rotating engine architectures preferredBackground in pressure v
