• Excellent written & oral communication, strong documentation skills.

• Comfortable working in a team, collaborating cross‑functionally.

• Capacity to work in a fast‑paced dynamic environment, managing multiple tasks while maintaining high quality.

• Proficient in Microsoft Office (Word, Excel, etc.).

Nice to Have / Plus Factors:

• Experience using flow cytometry for immunology research, immune cell phenotyping, or other cell‑based assays.

• Previous work in regulated environments (e.g. GLP / GMP).

• Experience designing or executing conjugation of fluorescent antibodies.

What You’ll Gain

• Opportunity to build strong expertise in flow cytometry, assay development, and reagent innovation.

• Hands‑on role in R&D where your contributions are visible and impactful.

• Exposure to process development, protocol writing, and regulatory science.

• Collaborative, mission‑driven environment with growing opportunities.

Physical Requirements

• Ability to lift up to 25 lbs safely.
