Applying synthetic biology, genomics, bioinformatics, data science, and fermentation, we harness the most beneficial molecules from plants to create active pharmaceutical ingredients in more controlled and economical ways. We are a close-knit team inspired by the possibilities of delivering transformative technologies and breakthrough science to change the course of medicine. We value our people as our most important resource and are always looking for talented individuals who can make valuable contributions to our efforts. As a key member of Antheia's Analytical Development group, you'll partner closely with the Downstream Processing (DSP) team to keep high-quality analytical data flowing for process development. This role is hands-on and lab-based, with a strong focus on chromatography (especially LC/HPLC) and routine sample preparation and analysis at meaningful scale. You'll thrive here if you enjoy steady bench work, take pride in careful execution, and bring a thoughtful, organized approach to managing multiple requests. You'll be supported by clear SOPs, a collaborative team, and a manager who trusts you to run your day while being available when you need guidance.

Responsibilities

• Prepare solvents, standards, reagents, and routine samples.
• Run and review chromatography-based assays (LC/HPLC-heavy; other techniques may include GC and ion chromatography).
• Manage incoming work via LIMS , track requests, and organize your workload so results are delivered on time.
• Review data, document results clearly, and keep meticulous records and archives.
• Perform routine instrument maintenance, basic troubleshooting, and calibrations.
• Support planning and scheduling of instrument time; communicate timelines with partner teams.
• Contribute to troubleshooting (for example, investigating unexpected peaks or instrument issues) as you grow in independence.

Requirements

• B.S. (or equivalent) in a hard science (Chemistry, Biochemistry, Analytical Chemistry, Chemical Engineering, etc.).
• 1 to 3+ years of hands-on chromatography experience (industry preferred; strong academic lab experience considered).
• Comfort with routine sample prep and running established SOP-based assays with care and consistency.
• Strong fundamentals with basic lab equipment and practices (balances, pH meters, glassware, etc.).
• A warm, organized, self-directed working style; you're someone who can manage requests, keep track of details, and communicate clearly without needing daily oversight.
• Nice-to-haves (helpful, not required)
• Small molecule pharmaceutical chromatography experience (especially LC/HPLC).
• Ion chromatography experience.
• Familiarity with common instrument ecosystems:
• Agilent (common for LC/GC/MS)
• Thermo/Dionex (ion chromatography)
• Experience with MS and related software, for example:
• ChemStation , Chromeleon , MassHunter
• Confidence troubleshooting routine instrument or data issues (you do not need to know every instrument, but you're comfortable learning and applying good judgment).
• Work location and schedule
• On-site, lab-based role (Menlo Park area).
• Typical business hours with some flexibility (for example, starting a bit earlier or later), as long as the work is getting done and communication stays strong.
