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
