Job Description

About Antheia:
Antheia is the advanced biosynthesis company transforming pharmaceutical manufacturing and innovation for the 21st century. Antheia’s commercially proven technology platform produces high-value pharmaceutical ingredients in a fraction of the time compared to legacy approaches while significantly reducing supply chain risk. The company provides its global pharmaceutical customers with a resilient, efficient supply of critical ingredients at scale, while expanding the innovation frontier for new therapeutic development. Backed by leading investors and recognized by the U.S. government as a priority technology for public health and national and economic security, Antheia is manufacturing the medicines the world needs today while enabling tomorrow’s breakthrough therapeutics.

Working at Antheia:
Our cross-functional team shares a vision for the future: improved pharmaceutical supply chains that can end drug shortages and drive equitable access to essential medicines. As a team, we aim to embody a culture that celebrates diversity, prioritizes knowledge sharing, encourages exploration and ideation, challenges constructively, and supports individuals in their professional and personal journeys. At Antheia, you can expect to be inspired by the science, by your teammates, and by the opportunity we have to bring about change in the pharmaceutical industry.

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.
