Research Associate II, Analytical Development

Menlo Park, CA

Who We Are:

Antheia is a science and technology company developing next generation plant-inspired medicines. 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.

About the role

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.

 What you’ll do

  • 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.

Must-haves

  • 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.

Why Antheia

  • Mission that matters: Antheia is changing how medicines are manufactured, with impact well beyond one site or one team.
  • A kind, high-performing culture: Smart, driven colleagues with low ego, plus a community that actually enjoys being together (team activities, events committee, etc.).
  • Mentorship and growth: Your hiring manager brings deep analytical chemistry experience (small molecule analysis, method development, scaling to manufacturing) and a mentorship-forward approach.
  • Exposure to a growing instrument suite: As you ramp, there is room to expand your assay ownership and learn additional techniques.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
