Employer immigration record

from this employer's Department of Labor filings

Files H-1B transfers

4 transfer filings in the last year, covering 4 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.

Sourced from Department of Labor LCA, PERM and prevailing-wage disclosure data. Employer matching is by name, so figures may be split across an employer's legal entities. Absence of a filing means none appears in our copy of the data, not that none exists.

About the role

  • We aggregate and analyze comprehensive health data - including blood tests, imaging, and longitudinal biomarkers - to provide members and clinicians with actionable, clinically meaningful insights.
  • The Function proactive health dataset includes whole-body MRI, 100+ blood biomarkers, radiology reports, questionnaires and, increasingly, wearables data, all linked to the same individual and refreshed over time.
  • The Medical Intelligence Lab (MIL) at Function exists to turn that data into an early-warning system for every member.

Responsibilities

  • Build and maintain the evaluation framework that decides what we ship: powered validation sets, confidence intervals, label-efficiency curves, forecasting metrics, collapse diagnostics, and benchmark registration against MIL's clinically validated specialist models.
  • Development and Delivery Own the training and evaluation codebase end to end: data loaders over our standardized research exports, distributed training on GPU infrastructure, experiment tracking, versioned model releases with model cards and licence inventories.
  • Deliver pretrained encoders and forecasters to MIL's product-track teams as documented, reproducible artefacts, and support their integration through clinical validation and hand-off to Engineering and Product Development.
  • Science, Rigor and Responsible ML Differentiate between predictive and causal claims: we forecast from observational data and validate before we assert.
  • Design analyses so that limitations are explicit and reviewable.
  • Write it down: experiment logs, design notes, and the periodic "what we learned" retrospectives that shape the roadmap.
  • We are building models that can do two things:
  • You will design and train the models, own the evidence that they work, and ship them as the pretrained foundation upon which a portfolio of MIL products and tools build.
  • The work is expected to reach large numbers of members and also the scientific literature; we publish, and we deliver.

Requirements

  • You are a researcher who likes to ship and/or an engineer who insists on evidence.
  • You are comfortable being early

Nice to have

  • Work with longitudinal cohorts or biobank-scale data (e.g., UK Biobank, NAKO, ADNI) or with EHR/lab time series.
  • Tabular foundation models or numeric tokenization for continuous clinical values
  • normative modelling
  • biological/organ-age estimation.
  • report information extraction with LLMs.
  • Cloud ML infrastructure (AWS, Databricks)
  • Prior experience as a founding or early member of a research team.
  • What's in it for you?

Benefits

  • Our mission Function Health's mission is to empower people to live longer, healthier lives through proactive, data-driven healthcare.
  • We believe individuals should understand their own health deeply, in context, and over time.
  • Our platform brings together complex medical data and transforms it into clear, trustworthy insights that support better health decisions.
  • Your mission Function Health is building something that has not existed before:
  • a multimodal, longitudinal picture of health for hundreds of thousands (soon to be millions) of people.
  • In a nutshell, we aim to design a new model of proactive, predictive and preventative health.
  • Team Lead and MIL's Chief Medical Scientist.
  • Research and Design Longitudinal health dynamics.
  • Multimodal health-state representation.

Company info

  • Function Health's mission is to empower people to live longer, healthier lives through proactive, data-driven healthcare.
  • Your mission Function Health is building something that has not existed before: a multimodal, longitudinal picture of health for hundreds of thousands (soon to be millions) of people.
  • The World Model team's job is at the core of that ambition.
  • We are building models that can do two things: represent a member's health today from whatever data exists historically, and predict how that state evolves, what the next lab panel is likely to show, what the next scan is likely to find, and eventually how that trajectory changes under an intervention.
  • As a Research Scientist on this team you will be a key technical contributor, working directly with the Team Lead and MIL's Chief Medical Scientist.
