Job Title: Mechanical Test Engineer

Job Description

This role focuses on hands-on testing and data collection related to stool sample handling and preparation to support the development of an advanced lab automation diagnostic product. You will work in a discovery-driven environment where you define, execute, and refine tests around sample characteristics, processing forces and parameters, and contamination mitigation techniques. The position requires a methodical, detail-oriented engineer who can perform repetitive testing without frustration, interpret findings, and provide input that guides further experimentation and design decisions. This opportunity offers exposure to cutting-edge diagnostic automation and provides strong experience for building a technical resume.

Responsibilities

• Perform hands-on testing of stool sample handling and preparation, including evaluation of sample characteristics, processing forces, and key process parameters.
• Collect, record, and organize test data accurately and consistently using Excel and other data collection tools.
• Analyze test results to identify trends, issues, and opportunities for improvement in sample handling processes and fixtures.
• Develop, refine, and execute test protocols as discovery progresses, adapting to changes in test scope and requirements.
• Operate and maintain test equipment, fixtures, and automation-related hardware used for mechanical and biomedical testing.
• Apply mechanical aptitude to set up, adjust, and troubleshoot test fixtures, automation components, and related lab equipment.
• Perform lab-based tasks such as pipetting, liquid handling, and use of vortex equipment to support test procedures.
• Handle human specimens (specifically stool) safely and consistently in a confined workspace, following established procedures and maintaining high attention to detail.
• Use cameras or imaging equipment to document tests, capture visual data, and support data analysis and reporting.
• Prepare and present data analysis and test findings in a clear, structured format to engineering stakeholders.
• Provide feedback and technical input that helps guide further testing and informs the design of automated diagnostic products.
• Work independently with minimal supervision while maintaining rigorous documentation and adherence to test plans.
• Contribute to validation activities by supporting test design, execution, and documentation for pre-alpha discovery testing.

Essential Skills

• 2–5 years of experience in Mechanical Engineering or Biomedical Engineering.
• Test experience in a mechanical or biomedical context, including planning and executing test protocols.
• Strong mechanical aptitude, particularly in testing, fixtures, and automation-related systems.
• Proven experience in data collection and data analysis, with proficiency in Excel.
• Laboratory experience with pipetting and liquid handling.
• Ability to work methodically and with high attention to detail in repetitive testing environments.
• Comfort and resilience working continuously with human stool samples in a confined area.
• Capability to work independently and maintain consistent, accurate documentation of test activities.

Additional Skills & Qualifications

• Experience handling human specimens, preferably stool.
• Experience using vortex equipment in a laboratory environment.
• Experience operating cameras or imaging systems to document tests and capture visual data.
• Experience preparing and delivering data analysis presentations to technical audiences.
• Experience designing or contributing to the design of automated products, particularly diagnostic or lab automation systems.
• Expereince in biomedical engineering or related disciplines supporting diagnostic product development.
