Micro Precision information

What is the difference between Micro Precision vs Micro Quality Control Technician?

AspectMicro PrecisionMicro Quality Control Technician
CertificationsOften requires calibration and measurement certificationsRequires quality assurance and inspection certifications
Work EnvironmentLaboratories, manufacturing plants, precision measurement settingsQuality labs, manufacturing facilities, inspection sites
Industry UsageManufacturing, electronics, aerospaceManufacturing, pharmaceuticals, electronics

Micro Precision focuses on precise measurement and calibration tasks, ensuring equipment accuracy. Micro Quality Control Technicians perform inspections and quality checks to maintain product standards. While both roles require attention to detail and related certifications, Micro Precision emphasizes measurement accuracy, whereas Micro Quality Control Technicians focus on product quality assurance.

What is a micro precision technician?

A micro precision technician is a specialist who works with extremely small components and precise measurements, often in industries like electronics, aerospace, or medical device manufacturing. Their role involves using specialized tools and equipment to assemble, calibrate, inspect, or repair micro-scale parts with high accuracy. Attention to detail and a steady hand are essential for this job, as even the smallest error can affect product quality or functionality. Micro precision technicians may also be responsible for maintaining equipment and ensuring work meets strict industry standards.

What are some common challenges faced by professionals working in micro precision manufacturing, and how can they be addressed?

Professionals in micro precision manufacturing often encounter challenges such as maintaining extremely tight tolerances, minimizing defects, and ensuring product consistency at a microscopic scale. These challenges can be addressed by adopting advanced quality control processes, utilizing cutting-edge equipment, and continuously updating technical skills. Collaboration with engineering and quality assurance teams is also essential to troubleshoot issues and optimize production methods. Ongoing training and attention to detail are key to overcoming these challenges and succeeding in this specialized field.

What are the key skills and qualifications needed to thrive in a micro precision technician role?

To thrive as a Micro Precision Technician, you need a strong background in precision measurement, calibration, and quality control, often supported by technical training or an associate degree in electronics or metrology. Familiarity with calibration equipment, micrometers, oscilloscopes, and relevant standards such as ISO/IEC 17025 is typically required. Attention to detail, problem-solving, and strong organizational skills help you excel in this meticulous field. These skills ensure the accurate maintenance and verification of instruments critical to manufacturing, research, and safety standards.

Job description

Join our fast-paced and passionate team as a Opto-Mechanical Engineer 2. As we scale, you will be instrumental in building our foundation from the ground up. This is a dynamic, hands-on role for a self-starter who thrives in a fluid startup environment. You'll have the opportunity to work on cutting edge technologies, work closely with leadership, and develop and implement engineering practices that support our mission and growth. Your key responsibilities are as follows:

Design & Engineering

    • Photonic Component & Assembly Design: Design precision mechanical components and sub-assemblies for photonic systems, including optical isolators, fiber optic connectors, and micro-optic/crystal mounting solutions.
    • Precision Optomechanical Fixturing: Design and build custom assembly tooling, alignment jigs, and fabrication stations to support low-volume prototyping and high-volume production.
    • Tolerance & Thermal Analysis: Perform basic tolerance stack-up analysis and thermal/stress evaluations (FEA) to ensure optical alignment is maintained across operating temperatures and mechanical strain.

Production, Documentation & Material Tracking

    • Fabrication Drawings & Drafting: Create, release, and maintain detailed 2D fabrication drawings adhering to GD&T standards (ASME Y14.5) for CNC machining, precision molding, and sheet metal.
    • BOM & Material Tracking: Build and maintain Bills of Materials (BOMs), track engineering prototypes through procurement and fabrication, and manage component inventory for build cycles.
    • Engineering Change Management: Process Engineering Change Orders (ECOs) and update CAD models and documentation based on design reviews, supplier feedback, or assembly findings.

Prototype Testing & Lab Work

    • Hands-On Assembly & Integration: Support cleanroom or lab-level assembly and alignment of delicate optical and mechanical sub-assemblies using adhesive bonding (UV/epoxy), soldering, or precision mechanical fasteners.
    • Root Cause Analysis & Failure Mode Testing: Assist senior engineers in investigating design or manufacturing non-conformances, running root cause analysis (RCA), and implementing corrective actions.

Requirements

  • This position requires access to export-controlled information. Employment is contingent upon the applicant being a U.S. person as defined by 8 U.S.C. § 1324b(a)(3).

Experience:

  • A bachelor’s degree in mechanical engineering, Physics, or a related field.
  • A minimum of 2 years of relevant experience, ideally within a startup or technology company.

Skills:

  • CAD Expertise: Proficient in 3D CAD modeling and drawing generation (SolidWorks preferred) with demonstrated experience using GD&T (ASME Y14.5).
  • Optomechanical Design Basics: Familiarity with optomechanical mounting techniques (kinematic mounts, flexures, adhesive bonding of optics/crystals, glass-to-metal joints).
  • Fiber Optics & Micro-Packaging: Exposure to fiber handling, fiber alignment mechanisms, or micro-electronic/photonic packaging considerations.
  • DFM / DFA Awareness: Solid understanding of Design for Manufacturability (DFM) and Design for Assembly (DFA) across precision CNC machining, sheet metal, and small-scale assembly.
  • Hands-On Aptitude: Comfortable working in an optical cleanroom/lab environment using hand tools, torque drivers, and optical alignment or measurement equipment.

Benefits

The expected annual salary range for this position is $85,000-$125,000.

As a full-time employee, you will be eligible for Monarch’s comprehensive benefits package, which includes:

  • Medical, Dental, and Vision insurance
  • Fidelity 401(k) plan with 4% employer matching
  • 20 paid time off (PTO) days per year
  • 13 paid company holidays
  • 9/80 work schedule (every other Friday off)
