Scientist, Microbiome

Build the experimental engine powering the AI intelligence layer for human microbiology.

Microbiome research today lives in two worlds. Assay-heavy labs build truth datasets but lack AI to model the complexity. AI teams build promising models on existing data, but can't test causal mechanisms. We're working to narrow this gap. We are hiring a scientist to drive the wet-lab workstreams that generate the proprietary datasets behind our platform. You will execute stool-derived community culturing and anaerobic screening workflows that provide high-quality data to our models in the near term and chart new experiments beyond.

Reports To

Heidi Arjes (VP, R&D)

Responsibilities

  • Lead screening workstreams for stool-derived communities, including reliable anaerobic culture execution, sample handling, and day-to-day operations and experimental delivery.

  • Champion data quality and reproducibility across the pipeline, from sample intake through QC checkpoints, documentation, and downstream data handoff.

  • Continuously elevate core protocols by troubleshooting, optimizing parameters, and translating successful approaches into robust, scalable SOPs.

  • Drive experimental insight for microbiome–compound interaction studies, clearly communicating results, surfacing failure modes, and proposing actionable next steps.

  • Safe and disciplined execution under BSL-2 and anaerobic handling requirements, with rigorous sample tracking and protocol adherence.

Your Background

  • PhD in microbiology, microbiome science, molecular biology, or a related field; or MSc/BSc with 3+/5+ years industry experience in microbiology or microbiome workflows.

  • Hands-on experience culturing diverse microbes and standardizing/troubleshooting for optimal microbial growth. 

  • Experience generating reproducible experimental data with clear QC and documentation, executing and troubleshooting assays/screening workflows/equipment

  • Working knowledge of at least one microbiome-relevant readout, such as 16S/metataxonomy, metagenomics, metabolomics, or LC-MS-based workflows.

  • You approach new challenges with curiosity, rigor, and adaptability, and are comfortable in a fast-moving, flexible environment.

Nice to Have

  • Experience optimizing or scaling high-throughput screening workflows and onboarding new equipment or optimizing new assays.

  • Experience culturing stool-derived anaerobes or stool-derived microbes under anaerobic and BSL-2 conditions.

  • Experience working closely with cross-functional teammates, especially computational, data science, or ML teams.

  • Experience working effectively in a startup or other fast-moving, resource-constrained environment.

Why Join Outpost Bio?

  • You'll be the first. You'll help build the experimental infrastructure from the start, influence the workflows, and shape how we generate the proprietary datasets that decode the human microbiome. 

  • An ML Lab-in-the-loop. Every screen you execute feeds directly into Outpost's AI platform. You'll collaborate with our ML team in a tight feedback loop: your data improves the models, the models guide your next experiments. 

  • You'll own real equity in what you build. We offer meaningful ISO stock options because we believe the people building this company should share in what it becomes. We want teammates who think like owners, and we structure compensation to reflect that.

  • Outstanding benefits. Full medical, dental, and vision coverage from day one (Outpost covers 100% of employee premiums). 401(k) with match. 25 days PTO plus your birthday off. Short- and long-term disability, and commuter benefits.

  • Small team, outsized reach. You're joining a small founding team backed by top-tier investors with deep connections across AI and Bio. The science you do here will directly shape how pharma/consumer companies understand molecule<>microbiome interactions.

About Us

Outpost Bio pairs high-throughput functional assays of human-derived microbial communities with causal machine learning to build predictive models of microbiome-compound interactions. We generate large-scale perturbation datasets using stool-derived communities (SDCs) and multi-omic measurements, then train frontier models that predict metabolism, toxicity, and response at the community level. Headquartered in Boston and London, we’re building the team to create a category-defining platform that transforms R&D.

Work on a problem that matters.

Our mission is ambitious, and our standards are high. Our culture is built on intellectual honesty, deep ownership, reliably doing what we say we will do. If you are a builder who thrives on candid feedback and are ready to do the best work of your career, we would love to meet you.

An open invitation to researchers.

We’re building AI to predict how interventions impact the human microbiome and will be contributing foundational datasets and models back to the scientific community. We’re seeking collaborators with rich pre/post-intervention datasets of the microbiome. We'll offer partners rich insights to existing datasets.
