At Janicki Industries, we turn complex ideas into real-world solutions through advanced engineering and manufacturing. Our teams design and build innovative structures, tooling, and systems that support industries including aerospace, space, defense, marine, and architecture.

Across every role—from engineers and technicians to operations and support teams—our people help solve challenging problems, push the limits of design and manufacturing, and create solutions that make a lasting impact.

this position is located in Sedro Woolley, Washington State.

We are looking for a Senior Mechanical Engineer to design and develop gearboxes and power transmission systems used in industrial equipment and heavy machinery. This role will directly support our machine build efforts as we expand our capabilities and locations. The ideal candidate has a strong foundation in gear theory, mechanical design, and structural analysis, and enjoys taking a product from concept through manufacturing and test validation

• Design gearboxes and related drivetrain components (gears, shafts, bearings, housings) to meet performance, durability, cost, and schedule targets
• Perform gear design calculations (bending, contact stress, scoring) per AGMA/ISO/DIN standards
• Size and select bearings, seals, and lubrication systems for reliable operation
• Own designs from concept through detailed design, prototyping, manufacturing support, and test validation
• Create 3D models, detailed drawings, and GD&T specifications using CAD software (Solid Works, Inventor, Creo, or similar)
• Run structural, thermal, and vibration analysis (FEA) to validate designs
• Collaborate with manufacturing, quality, and test teams to resolve design and production issues
• Support prototype builds, testing, and root-cause failure analysis
• Prepare design calculations, technical reports, and documentation for design reviews
• Ensure designs meet applicable industry standards and customer specifications
• Work with suppliers on castings, forgings, and purchased components
• Mentor junior engineers and help establish design standards and best practices as the team scales
• Must work well under pressure, meeting and completing multiple deadlines.
• Must be at work on time and maintain good attendance. This is a condition of employment and is an essential function of the job
• Performs other duties as assigned.

• Bachelor's degree in Mechanical Engineering (Master's preferred)
• 5+ years of experience designing gearboxes or power transmission equipment
• Strong knowledge of gear theory, AGMA/ISO gear rating standards, and lubrication principles
• Proficiency with 3D CAD software and gear design/analysis tools (e.g., KISSsoft, MASTA, Romax, or similar)
• Experience with FEA software (ANSYS, Abaqus, or similar) for structural and thermal analysis
• Solid understanding of GD&T, tolerance stack-up, and manufacturing processes (gear cutting, grinding, heat treatment)
• Familiarity with bearing selection and shaft design principles
• Strong analytical, problem-solving, and communication skills
• Experience with large industrial gearboxes (wind, mining, marine, or oil & gas applications)
• Knowledge of noise/vibration (NVH) analysis for gear systems
• Experience with project management and customer-facing technical roles
• Due to our ITAR and EAR regulations applicants must be a US Citizen or Legal Permanent Resident as defined by 8 U.S.C. 1324b (a)(3)
