Duration: 03 Months Location: San Francisco, CA - 100% onsite in the R&D laboratory. This role is expected to work in the lab all scheduled workdays; remote work is not anticipated.
Hours: 40 hours per week, Monday-Friday, with work schedule aligned to laboratory and team needs.
Initial 3-month contract with the possibility of renewal/extension based on business need, workload, and performance. No conversion to a permanent role is guaranteed.
Job Description:- This is a full-time, laboratory-based contractor role created to support a high volume of product stability work that must be completed within a tight project timeline. The contractor will work closely with approximately 4-5 formulators and will primarily own the day-to-day execution, tracking, and documentation of stability studies while providing additional hands-on formulation lab support as needed.
- Set up, organize, label, place, pull, and track stability samples according to defined study protocols and timelines.
- Perform routine stability evaluations and physicochemical measurements such as appearance, color/odor observations, pH, viscosity, and other defined test methods.
- Maintain accurate stability trackers, laboratory records, and sample traceability; summarize data and identify trends or changes over time.
- Promptly communicate missed pulls, unusual observations, test deviations, or potential stability failures to the responsible formulator.
- Prepare laboratory batches, dilutions, or test samples as directed by formulators and support basic formulation work when stability workload allows.
- Coordinate priorities across multiple projects/formulators and proactively manage daily and weekly testing schedules to meet deadlines.
- Maintain good laboratory hygiene and safety practices and support routine instrument care, calibration checks, and readiness of commonly used lab equipment.
- Support laboratory inventory, materials/sample organization, and general lab readiness so testing can proceed efficiently.
- Provide clear, timely progress updates and work collaboratively with the formulation team; perform other related laboratory duties as assigned.
Required Education:
- High school diploma or equivalent required. Technical certificate, Associate degree, or coursework in Chemistry, Laboratory Science, Chemical Technology, or a related field preferred. A college degree is not required if the candidate has relevant hands-on laboratory experience.
Top 5 Required Skills:
- Hands-on laboratory experience with the ability to work independently and safely in a formulation/R&D lab environment.
- Ability to perform and document basic physicochemical testing, including pH and viscosity measurements, using standard laboratory equipment.
- Strong organization and multitasking skills to manage a high volume of stability studies, sample pulls, measurements, and deadlines concurrently.
- Accurate data recording and attention to detail; able to recognize changes, deviations, or potential out-of-specification results and escalate promptly.
- Strong communication and collaboration skills to support 4-5 formulators at a time, provide timely status updates, and respond proactively to lab priorities.
Technology Proficiencies:
- pH meters; viscometers (e.g., Brookfield or equivalent); laboratory balances; temperature-controlled stability chambers/ovens; standard lab equipment; Microsoft Excel/Office for data tracking and summaries. Experience with electronic lab records, SAP, or PLM is a plus.
Preferred Attributes:
- 1-2+ years of hands-on laboratory experience in consumer products, home care, personal care, or a related formulation environment; prior stability testing experience; familiarity with good laboratory practices, sample traceability, and instrument calibration checks; quick learner who is dependable, collaborative, flexible, and attentive to day-to-day lab needs.
