Responsibilities

• Assemble small catheter components in a cleanroom environment according to detailed procedures and quality standards.
• Work under a microscope for extended periods to perform fine, detailed assembly work.
• Use small hand tools to handle, position, and assemble tiny parts, including coiling wire and small tubing.
• Follow all cleanroom protocols, including gowning procedures and contamination control practices.
• Maintain high levels of quality and accuracy while meeting production goals and timelines.
• Demonstrate reliable attendance and punctuality, especially during the first 90 days of employment.
• Participate in and pass a hands-on assessment to demonstrate basic assembly and hand tool skills.
• Collaborate and communicate effectively with team members while maintaining focus on quality and productivity.
• Work the assigned shift schedule, including long shifts and frequent overtime as needed.

Essential Skills

• Ability to work under a microscope for long periods of time.
• Proficiency using small hand tools for detailed assembly work.
• Capability to work long hours, including extended shifts and frequent overtime.
• Strong attention to detail and ability to perform precise, repetitive tasks.
• Reliable attendance and punctuality, especially within the first 90 days.
• Ability to pass a hand assessment test to demonstrate fine motor and assembly skills.
• Comfort working in a cleanroom environment and following strict procedures.

Additional Skills & Qualifications

• Previous cleanroom experience is highly desired.
• Prior manufacturing or production experience is strongly preferred.
• Openness to entry-level candidates who can demonstrate strong hand skills and dependability.
• Willingness to learn and improve performance over time.
• Ability to build positive working relationships while maintaining quality and productivity.

Why Work Here?

• The organization offers a path from contract to permanent employment for individuals who demonstrate strong attendance, quality, and performance.
• Once hired on permanently, employees receive comprehensive benefits, including 100% coverage of their own benefits and partial coverage for their immediate family, along with a 401(k), paid time off, and holiday pay.
• The leadership values effort, dependability, and continuous learning rather than expecting instant expertise, and they provide multiple chances for those who show commitment and improvement.

Work Environment

• You will work in a controlled cleanroom environment and must wear full gowning at all times, following strict cleanliness and contamination control procedures.
• The culture in the cleanroom is supportive and collaborative, with encouragement to talk and build good relationships as long as quality and productivity remain high.
