About The Position

Allegro MicroSystems is building a pioneering team at the intersection of semiconductor technology and life sciences. We are seeking a highly motivated Senior Research Associate to become a foundational member of our new Manchester Molecular Sensors Laboratory. Working closely with the Principal Assay Scientist, you will play a key role in developing, validating, and scaling our Giant Magnetoresistance (GMR) biosensor platform. This position is ideal for a hands-on scientist who enjoys laboratory experimentation, problem-solving, and translating biological assays into robust sensor-based diagnostic solutions. You will contribute to the development of multi-modal assay workflows for protein, DNA, and RNA detection while helping establish the laboratory capabilities and processes needed to support future product development and customer applications.

Requirements

• B.S. or M.S. in Biochemistry, Molecular Biology, Bioengineering, Chemistry, or a related discipline.
• 3-6 years of hands-on laboratory experience in biotechnology, diagnostics, medical devices, or related R&D environments.
• Experience with standard laboratory techniques, including pipetting, solution preparation, dilution series, ELISA, or molecular biology workflows.
• Experience with surface chemistry, bioconjugation, or immobilization of biological capture reagents.
• Strong experimental design, troubleshooting, and data analysis skills.
• Proficiency in Excel and statistical analysis tools; experience with JMP, Python, or equivalent software is highly desirable.
• Excellent organizational skills and attention to detail.

Nice To Haves

• Experience working with biosensors, diagnostics, immunoassays, or molecular detection technologies.
• Familiarity with process development, manufacturing transfer, or semi-automated laboratory workflows.
• Experience working in highly multidisciplinary product development environments.
• Exposure to regulated product development or quality systems is a plus.

Responsibilities

• Execute and optimize biosensor assays across a variety of biological targets and sample matrices, including blood, serum, and saliva.
• Support development of protein, nucleic acid, and multiplexed assay formats for GMR sensing applications.
• Conduct experimental studies to improve assay performance, sensitivity, robustness, and reproducibility.
• Perform surface functionalization, bioconjugation, and immobilization processes on sensor substrates.
• Support the development, characterization, and optimization of surface chemistry workflows for biosensor manufacturing and scale-up.
• Contribute to process improvement initiatives aimed at increasing assay consistency and performance.
• Analyze experimental results using tools such as Excel, JMP, Python, or equivalent platforms.
• Identify technical trends, troubleshoot assay challenges, and communicate findings clearly to project stakeholders.
• Collaborate with scientists and engineers to develop innovative solutions for improving sensor performance and assay sensitivity.
• Prepare reagents, buffers, controls, and test samples to support R&D activities.
• Maintain laboratory inventory, equipment calibration, documentation, and standard operating procedures.
• Ensure laboratory activities comply with safety and quality requirements.
• Assist in developing proof-of-concept demonstrations and customer-specific validation studies.
• Generate technical data and reports supporting customer evaluations, product verification, and manufacturing transfer activities.
• Support high-priority customer testing and application development efforts.
• Partner with electrical, mechanical, software, and manufacturing engineers to integrate biological assay requirements into system design.
• Provide biological and assay-development expertise during product development, verification, and troubleshooting activities.

Benefits

• We foster a culture of Real Innovation, empowering you to push boundaries, develop cutting-edge solutions, and drive continuous improvement.
• Your work will create a Real Impact by solving complex real-world challenges that fuel our success and shape the future of technology.
• You’ll experience Real Connection, collaborating with talented colleagues around the globe in an environment built on trust, respect, and a shared purpose.
