Senior Laboratory Assistant

Commitment: Full-time 

Experience Level: Bachelor’s degree, Master’s, or equivalent lab experience

The Role

We’re looking for an exceptional and hard-working Senior Laboratory Assistant to support both histology workflows and day-to-day lab operations at Conception. This is a lab operations–focused, hands-on role for someone who thrives in the lab environment, enjoys keeping things running smoothly, and is comfortable taking on a wide range of essential tasks behind the scenes.

The ideal candidate is a professional-level lab assistant who has built their career supporting scientific teams—someone dependable, detail-oriented, and confident with core lab skills like pipetting and media prep. At a minimum, you must have prior lab experience and be able to use pipettes reliably.

While this role offers opportunities for cross-training and growth within lab operations, it is not currently structured as a path toward a scientific or research-track position. We’re looking for someone ready to commit to a 2-year role as part of our Lab Operations team, contributing meaningfully to the success of our R&D work through strong operational support.

What You’ll Be Doing

Histology Support - 40% (Training Provided)

• Assist with manual immunofluorescence staining

• Handle slides, reagents, and staining materials

• Support preparation and coordination for imaging workflows

• Aliquote and maintain antibody stocks

Lab Operations & Sample Logistics - 60%

• Label tubes for sample collections (e.g., immunofluorescence and NGS workflows)

• Assist scientists during sample collection, handling materials, and prepping samples

• Bulk label tubes for small molecule aliquoting

• Prepare media and buffers for the scientific team

• Help with stock audits, inventory restocking, and tracking

• Clean and maintain incubators and other lab equipment as needed

• Prepare and support sample shipments (e.g., NGS, external assays)

• Keep lab spaces organized and stocked, including weekly cleaning and maintenance of operations support

Who We’re Looking For

We’re looking for someone who is exceptional at what they do—highly dependable, detail-focused, and energized by helping a lab run efficiently. You should be motivated by being part of a larger mission and take real pride in supporting the daily work of scientists. Flexibility is key—you’re the kind of person who can adjust to shifting needs and jump in where help is needed. 

Bonus Points For

• Experience in histology or immunostaining

• Familiarity with lab stock systems or media/buffer prep

• Sample handling and support during live experiments

• Experience cleaning and maintaining cell culture equipment

• Interest in Conception’s mission and biotech operations
