Research Associate, Analytical
Job type: Full Time · Department: Product · Work type: On-Site · USD 80000 - 100000 / year
South San Francisco, California, United States
We’re looking for an Analytical Research Associate to support our materials and product development efforts through hands-on analytical testing, with a primary focus on gel permeation chromatography (GPC). This is an early career, lab-intensive role ideal for someone who enjoys running samples, maintaining instruments, and ensuring high-quality, reproducible data in a fast-moving research environment.
In this role, you’ll spend the majority of your time preparing and running polymer samples on our GPC systems, working closely with an analytical scientist and collaborating with scientists across the materials team. You’ll also play an important role in instrument maintenance, calibration, troubleshooting, and documentation - helping ensure our analytical methods perform consistently and reliably.
While this role is primarily execution-focused, it offers room to grow over time into deeper analytical ownership, including method development and expanded responsibility across chromatography-based techniques.
You’re someone who enjoys being in the lab, takes pride in producing reliable data, and thrives in a small, highly technical startup environment. You balance attention to detail with flexibility and creativity, communicate clearly with teammates, and aren’t afraid to flag issues early when something doesn’t look right.
Prepare and run polymer samples on GPC systems, following established methods and SOPs
Track method performance to ensure data quality, reproducibility, and consistency over time
Perform routine instrument maintenance, calibration, and troubleshooting, escalating issues as needed
Identify clearly problematic or compromised data and communicate issues proactively
Collaborate closely with an analytical scientist on scheduling, priorities, and technical problem-solving
Support materials scientists and engineers by running analytical tests for ongoing experiments
Maintain accurate records of experiments, maintenance, and calibrations
Contribute to writing or updating SOPs and best practices as the lab and team evolve
Over time, take on additional ownership such as consumables management, method improvements, or expanded analytical scope
Required / Core Skills
Hands-on experience running samples on a SEC/GPC or similar LC system (academic or industry)
Strong fundamentals in chromatography and laboratory best practices
Experience working with polymers (synthetic and/or biopolymers)
High attention to detail and commitment to data quality
Comfort working independently while collaborating closely with others
Ability to recognize when data or samples are clearly problematic and speak up
Safe lab practices, including handling chemicals, solvents, and glassware
Nice to Have
Industry experience (1-3 years preferred, but not required)
Exposure to instrument calibration, maintenance, or troubleshooting
Experience with multiple analytical techniques beyond GPC
Familiarity with rheology or interest in learning additional techniques
Experience contributing to SOPs or method documentation
This role is designed to grow with the right person. As our analytical needs expand, strong performers may take on:
Greater ownership of GPC methods and performance tracking
Involvement in method development and optimization
Broader analytical responsibilities across chromatography-based techniques
A longer-term path toward expanded scientific or technical roles, aligned with individual interests
