Want to be part of a team that’s making a difference to human health?

About the role:

The Manufacturing Test Manager leads all testing of precision dispensing head assemblies before they ship, from incoming inspection through final leak and functional release. You will develop and carry out a test strategy that supports production schedules, standardize test processes and SOPs, and drive root cause analysis on test failures. The role makes the go/no-go release decision on each unit and works closely with production, supplier quality and our international engineering team.

DUTIES AND ESSENTIAL JOB FUNCTIONS:

Test strategy and operations

• Develop and implement a manufacturing test strategy that supports production schedules and business goals.
• Oversee test operations day to day: scheduling, staffing, equipment and throughput against the production plan.
• Own the full test lifecycle, from test requirements and test plans through execution, defect tracking and reporting.
• Own leak, pressure-decay and functional test procedures; set pass/fail criteria with engineering.
• Maintain golden reference units so results stay comparable over time.
• Keep test fixtures and instruments calibrated and maintained to minimize downtime.
• Allocate and manage test resources, including people, equipment and budget.

Failure analysis and continuous improvement

• Lead root cause analysis on test failures using 8D, 5-Why and fishbone methods, and track corrective actions to closure.
• Design and run structured test plans (DOE) to isolate causes such as seal gland depth, bore surface finish, burrs and cleaning residue.
• Arrange outside metrology when in-house capability falls short.
• Drive continuous improvement and cost reduction through test automation and process simplification.
• Evaluate and introduce new test technologies, tools and methods.

Quality and compliance

• Standardize test processes, SOPs, work instructions and records under the ISO 9001 quality system.
• Execute nonconformance (NCR) and CAPA procedures tied to test results.
• Establish and monitor KPIs for yield, throughput and quality, and brief senior leadership on performance and risks.
• Support CE marking and customer audits with complete, traceable test records.

New product introduction and cross-functional work

• Support new product introduction and design transfer, including test method development and validation.
• Work with supplier quality on incoming inspection of machined parts; feed test data back to suppliers.
• Partner with assembly teams on build practices that affect test yield.
• Represent test in cross-functional forums and act as the site test contact for the international engineering team.

People leadership

• Hire, train, certify and mentor test technicians; lead performance reviews and career development.
• matrix current and build a culture of accurate data and early escalation.

Requirements

• Bachelor's degree in mechanical, manufacturing, electrical or quality engineering, or equivalent experience.
• 7+ years in test, quality or manufacturing engineering for precision instruments, medical devices or fluidic assemblies
• 2+ years managing technicians or a manufacturing test team.
• Hands-on experience with leak and pressure-decay testing and sealing design (O-rings, gland dimensions).
• Working knowledge of GD&T, surface finish specs and reading mechanical drawings.
• Proven use of structured RCA methods (8D, 5-Why, fishbone) and statistics (SPC, Cp/Cpk, DOE).
• Experience working under ISO 9001, including NCR/CAPA and document control.
• Experience with SAP or an equivalent ERP system.
• Strong communication at all levels and the ability to make independent, informed decisions under tight deadlines and changing priorities

Preferred qualifications

• Experience with liquid-handling or life-science lab automation instruments.
• Familiarity with surface metrology (profilometry or optical measurement systems) and machined-part cleanliness (deburring, residue).
• Knowledge of stainless steel grades for machined parts and passivation.
• Background in Lean Manufacturing; ASQ certification (CQE, CQM or CRE) or Six Sigma Green/Black Belt.
• Test automation experience, such as LabVIEW or Python.
• Experience with CE marking technical files and customer or notified-body audits.
• Multi-site experience working with an overseas engineering or parent-company team.
