What are the typical projects or challenges faced in a Bayesian-focused role?

In a Bayesian role, you’ll often work on projects involving probabilistic modeling, uncertainty quantification, and predictive analytics for real-world decision-making. Common challenges include structuring prior distributions, ensuring computational efficiency for complex models, and clearly explaining Bayesian results to non-technical stakeholders. You might collaborate closely with data engineers, domain experts, and business analysts to refine models and translate findings into actionable recommendations. This role offers the opportunity to tackle diverse analytical problems across industries like healthcare, finance, or tech, supporting ongoing professional growth and learning.

What is a Bayesian job?

A Bayesian job typically involves applying Bayesian statistics, probabilistic modeling, and inference techniques to analyze data and make decisions under uncertainty. Professionals in this field use Bayes' theorem to update beliefs based on new evidence, often working in areas like machine learning, finance, healthcare, and research. Common roles include Bayesian statisticians, data scientists, and researchers who build probabilistic models to improve predictions and decision-making.

What are the key skills and qualifications needed to thrive in the Bayesian position, and why are they important?

To thrive as a Bayesian (typically a Bayesian Data Scientist or Statistician), you need a strong background in probability theory, statistical modeling, and mathematics, often with an advanced degree in statistics, data science, or a related quantitative field. Experience with programming languages such as Python or R, Bayesian analysis libraries (e.g., Stan, PyMC), and familiarity with statistical software are commonly required. Analytical thinking, collaborative teamwork, and the ability to communicate complex results clearly are valuable soft skills in this role. These abilities are essential for designing robust models, interpreting data accurately, and delivering actionable insights to interdisciplinary teams.

ML Research Scientist - Bayesian Optimization

Merge Labs

San Francisco, CA • On-site

$200K - $270K/yr

Full-time

Posted 5 days ago


Key responsibilities

  • Design and scale Bayesian optimization and reinforcement-learning frameworks to guide molecular engineering campaigns through iterative design-build-test-learn cycles.

  • Build scientific and engineering scaffolding for active-learning and closed-loop optimization, including data ingestion, ML modeling, and library design.

  • Collaborate with wet-lab scientists to define optimization objectives and encode domain-specific priors and constraints.


Job description

Merge Labs is a frontier research lab with the mission of bridging biological and artificial intelligence to maximize human ability, agency and experience. We're pursuing this goal by developingfundamentally new approaches to brain-computer interfaces that interact with the brain at high bandwidth, integrate with advanced AI, and are ultimately safe and accessible for anyone to use.
About the team:
Merge is building the next generation of brain-computer interfaces by combining recent advances in synthetic biology, neuroscience, AI, and non-invasive imaging. To support this mission, we are building a cross-functional data-science group which sits at the intersection of computational modeling, neuroscience, and biomolecular engineering. This group collaborates extensively with wet-lab scientists, automation engineers, and data engineers to create ML frameworks that accelerate molecule discovery and device optimization.
About the role:
We're hiring a Senior / Principal ML Scientist to design and scale Bayesian optimization and reinforcement-learning frameworks that guide molecular engineering campaigns through iterative design-build-test-learn (DBTL) cycles. Starting from a blank slate, you'll first architect the company's closed-loop optimization backbone- building the data and modeling foundations that connect experiments to these ML frameworks. Over time, you'll help translate these prototypes into production pipelines that measurably improve experimental throughput and discovery success across multiple biomolecular and neuroengineering verticals.
In this role, you will:
  • Build the scientific and engineering scaffolding for active-learning and closed-loop optimization, including data ingestion, ML modeling, and library design.
  • Collaborate with wet-lab scientists to define tractable optimization objectives and encode domain specific priors and constraints.
  • Prototype representation-learning and acquisition-strategy using internal and public datasets; benchmark and validate model performance.
  • Integrate ML models with experimental data streams and serve to non-domain experts for model democratization.
  • Extend ML frameworks to handle multi-objective or constrained optimization problems.
  • Stay up-to-date with the latest research in Bayesian optimization, active learning, and RL, and prototype novel algorithms that can be deployed to improve the company's discovery or development workflows.
  • Contribute to the long-term research roadmap and serve as a thought-leader for scientists.

You might thrive in this role if you have:
  • Strong grounding in probabilistic modeling, uncertainty quantification, and representation learning.
  • Working knowledge of preference optimization and transfer-learning strategies
  • Proficiency in Python / PyTorch / BoTorch / Pyro (or similar) and comfort writing clean, reproducible production grade code.
  • Experience bridging machine learning and experimental science - working with sparse, noisy, and or high-cost data.
  • A collaborative, systems-level mindset.

Nice to have
  • Familiarity with neuroscience.
  • Familiarity with language / state-space models.

If you're excited about this role but don't meet every qualification, please apply. As we build, we're hiring for complementary strengths to form a high-impact team.
