What they're building

AI systems that design modular biological machines moderate signal

Today: "We develop the AI systems that design modular biological machines and the experimental infrastructure to instantiate them." (anthrogen.com)

Roles: Member of Technical Staff (Research Engineer) · Member of Technical Staff (Research Scientist)

Requirements mention: strong Python · distributed training · GPU optimization · inference and serving at scale · generative models · diffusion · autoregressive

Inference: the two Technical Staff roles, both opened 2026-07-07, point to model training and serving work alongside the lab build-out. The postings do not say more than this.

Experimental infrastructure to construct and measure designed assemblies, including robotic lab work strong signal

Today: "We build the experimental infrastructure to construct these assemblies and return what we learn to the models." (anthrogen.com)

Roles: Research Associate (Biology) · Member of Platform Science (Research Scientist) · Research Associate (RL Environments)

Requirements mention: cloning · PCR · mammalian cell culture · transfection · high-throughput experimentation · lab automation · robotic lab · Opentrons · Hamilton · Tecan · liquid handlers

Inference: three Platform roles, all in San Francisco, suggest the wet-lab side is being staffed in parallel with the AI side, with automated and robotic lab work named in the postings. The postings do not say more than this.

In-vivo research for designed biological systems weak signal

Today: "We build the experimental infrastructure to construct these assemblies and return what we learn to the models." (anthrogen.com)

Roles: Member of Platform Science (Research Scientist, In-vivo)

Requirements mention: in-vivo research · pharmacokinetics · pharmacodynamics · animal-care protocols · translational biomarkers

Where the headcount is going

Department	Open
Platform	4
Technical Staff	2
De Novo	1
Operations	1

Eight postings in San Francisco, none remote: seven defined roles plus one open-ended De Novo posting with a placeholder title; Platform holds the most (4), then Technical Staff (2) and Operations (1).

Who they need

Seniority: Two senior, two mid, two junior, and two with no level stated.

Skills named most: Python, R, cloning, PCR, transformations, liquid handlers, distributed training, GPU optimization, experimental infrastructure, AI systems, in-vivo research, pharmacokinetics

Locations: All eight postings are listed as San Francisco, none remote.

You'd fit if you have molecular biology protocols, cloning, transformations, PCR, protein expression and purification, assay development, lab technique, Python or scripting, and experience with robotic lab platforms, and you can work in San Francisco (Research Associate, RL Environments).
You'd fit if you have strong Python, a systems language, production-grade code, distributed training, GPU optimization, PyTorch and JAX, and you can work in San Francisco (Member of Technical Staff, Research Engineer).
You'd fit if you have in-vivo research experience, pharmacokinetics, pharmacodynamics, animal-care protocols, quantitative analysis skills, and you can work in San Francisco (Member of Platform Science, In-vivo).

How to use this

If you're applying: Check the fit lines against your own background before applying; all roles are San Francisco-based and none are remote. The Platform wet-lab roles and the Technical Staff AI roles are the two clearest tracks. The De Novo posting has no defined title, so treat it as a general application. The Founding Operator role is the only one with a stated salary ($100,000-$200,000 base) and covers recruiting, onboarding, purchasing, facilities and public communications.

If you're selling or recruiting: Seven defined roles plus one open-ended posting, four of the defined roles in Platform, all San Francisco. The flag reads freeze because no roles opened in the last 30 days. Five roles opened on 2026-09-13 and none have closed, so this is a pause in new postings, not a cutback. The site describes Anthrogen as an AI research lab and names no products. A Founding Operator opening suggests operations, including recruiting and purchasing, is still being set up.
