  • You will develop and utilize custom fixtures, tools, and software solutions to control, characterize, and evaluate diagnostic systems.
  • You will identify potential failure modes and design robust assay sequences and algorithms that account for operational variability and system tolerances.
  • You will qualify assay sequences and algorithms against product requirements and performance expectations.
  • You will follow established engineering design, development, documentation, verification, and validation practices throughout the product lifecycle.
  • You will support continuous improvement initiatives that strengthen engineering capabilities and technical excellence across the organization.

  • You will specify, test, and implement software modifications to improve system functionality and performance.
  • You will collaborate closely with scientists, software engineers, hardware engineers, manufacturing partners, and business stakeholders to successfully integrate assays into new and existing diagnostic platforms.
  • You will manage and interpret characterization data to inform design decisions and support product development milestones.

What you need to succeed:

  • Bachelor's degree in Systems Engineering, Electrical Engineering, Mechanical Engineering, or a related engineering discipline, along with 3 to 5 years of professional experience. (Required)
  • Translate assay and reagent requirements into instrument sequence definitions and algorithm specifications. (Required)
  • Independently plan, prioritize, and manage your work while communicating status, risks, and commitments. (Required)
  • Experience analyzing test data, identifying probable failure modes, and developing and implementing appropriate mitigation strategies. (Required)
  • Design, build, and utilize fixtures that support system characterization and testing activities. (Required)
  • Experience working effectively within cross-functional product development teams. (Required)
  • Possess strong verbal and written communication skills and can explain complex technical concepts to a variety of audiences. (Required)
