Overview

You will be part of a collaborative team shaping the future of scientific instrumentation for applications across biopharma, biosciences, and advanced analytical workflows. With access to world-class scientists, research facilities, and multidisciplinary collaborators, you will help create enabling technologies that support new separations, sample handling approaches, microfluidic architectures, and bioscience workflows. This is a unique opportunity to influence foundational technology development and translate promising concepts into high-value instrumentation platforms.

Join our forward-thinking Instrumentation Research Group as a Senior Mechanical Engineer. You'll lead the development of innovative analytical systems and next-generation scientific instrumentation. We are committed to building a diverse team and fostering an inclusive workplace culture.

Responsibilities

• Lead mechanical design efforts for research-stage liquid chromatography, microfluidic, and bioscience instrumentation from concept through prototype demonstration. • Design and develop mechanical, fluidic, and electro-mechanical subsystems, including flow paths, microfluidic interfaces, sample handling components, precision assemblies, and thermal management features. • Drive the development of high-fidelity prototypes for early-stage concepts, learning loops, and subsystem feasibility studies. • Perform mechanical, fluidic, and thermal analysis using engineering fundamentals and simulation tools such as FEA to guide design decisions. • Collaborate closely with scientists, chemists, biologists, electrical engineers, software engineers, and systems engineers to translate research needs into robust hardware solutions. • Support the design of systems and components requiring careful consideration of dead volume, pressure tolerance, chemical compatibility, manufacturability, serviceability, and reliability. • Assemble, test, troubleshoot, and refine prototypes in the lab, using experimental data to improve performance and inform future design rules. • Contribute to ideation, concept generation, and technical scouting for emerging technologies in fluidics, separations, consumables, and bioscience workflows. • Incorporate Voice of the Customer (VoC) and user workflow understanding into design decisions where appropriate. • Document technical work through engineering reports, functional specifications, design records, and intellectual property disclosures. • Mentor junior engineers and contribute to a collaborative, inclusive, and innovation-driven team environment.

Qualifications

• PhD in Mechanical Engineering or related field, or M.S. with 3+ years, or B.S. with 5+ years in research, advanced development, or instrumentation-focused engineering environments. Advanced degree preferred.• Strong interdisciplinary engineering background with experience working on complex systems in research or advanced development environments. • Demonstrated success in the design and development of precision mechanical and/or fluidic systems. • Hands-on experience with prototype development, testing, troubleshooting, and iterative design refinement. • Proficiency in 3D CAD, preferably SolidWorks; familiarity with NX is a plus. • Experience with engineering analysis tools, including FEA and/or CFD. • Familiarity with GD&T, tolerance analysis, and precision mechanical design practices. • Strong written and verbal communication skills with the ability to work effectively across technical disciplines.

Key Experience

• Experience in liquid chromatography, microfluidics, life science instrumentation, consumables, sample preparation, or bioscience-related hardware development. • Experience designing components or subsystems involving fluid handling, valves, fittings, seals, manifolds, chip interfaces, cartridges, or low-volume flow paths. • Familiarity with bio-compatible materials, chemically resistant materials, and design constraints associated with biological or analytical samples. • Background in instrument miniaturization, precision assemblies, additive manufacturing, or advanced materials. • Experience working alongside scientists in bioscience, analytical chemistry, or advanced technology development settings. • Exposure to coding or data-analysis tools such as C++, Python, MATLAB, or LabVIEW is a plus. • Familiarity with technical publications, patent generation, and structured documentation.

Desired Skills

• Strong technical curiosity and creativity in solving multidisciplinary engineering challenges. • Ability to balance innovation with practical design considerations such as robustness, usability, and manufacturability. • Independent work ethic with a proactive, hands-on approach to prototype development and problem solving. • Strong collaboration and mentorship skills. • Clear decision-making and analytical thinking in ambiguous research environments.

• Advanced analytical and decision-making abilities.
