What You'll Do- Work a dedicated night-shift schedule, running chemistry workflows overnight so compounds are ready for characterization, testing, or handoff the next day.
- Execute overnight peptide synthesis workflows, including resin loading, coupling and deprotection cycles, cleavage, purification, analytical characterization, and sample preparation for testing.
- Run microwave-assisted solid-phase peptide synthesis during night-shift hours, support routine synthesizer maintenance, and help troubleshoot failed couplings, low crude purity, side products, cleavage issues, and instrument downtime.
- Purify and characterize peptide candidates using analytical HPLC, prep HPLC, LC-MS, and related methods; record identity, purity, yield, and batch-level QC data for morning handoff.
- Prepare compounds for in vitro and in vivo testing, maintain accurate experimental records, and communicate overnight synthesis results, issues, and timelines clearly to the day team.
Who You Are- You are specifically looking for or open to a night-shift lab role. You are comfortable working overnight hours, operating independently during quieter lab periods, and handing off clean, well-documented work to the day team.
- You have hands-on chemistry or biochemistry lab experience and strong experimental discipline. Your education path matters less than your ability to learn quickly, and care about the quality of the result.
- You're excited to own the overnight synthesis workflow: running reactions, purifying and characterizing compounds, documenting results, and preparing samples for testing with care and urgency.
- You are proactive and reliable when issues arise. When an instrument breaks, a synthesis fails, data look off, or a handoff is unclear, you document clearly, communicate early, and help troubleshoot toward a clean result.
Pay & Benefits- In addition to the posted salary range, we offer generous equity options.
- Compensation will depend on the skills, experience, and scope of impact you bring. If your background, experience, or compensation needs fall outside this range, we are still open to a conversation based on the scope and impact you could bring.
- $500+ monthly wellness budget for training, supplements, coaching, recovery, or other tools that help you perform at your best.
- Healthcare: We offer a broad range of medical, dental, and vision coverage options, with Capable covering 100% of the base policy.
- You will also have access to HSA, FSA, and 401K plans.
- Healthy dinners with the team are provided daily.
- We support visa sponsorship where appropriate, including O-1, H-1B, J-1, TN, and other employment-based pathways. Our team is already international, with members from Canada, Pakistan, Germany, Austria, Switzerland, China, India, and the United States.
