- **Company:** Epistemix
- **Location:** United States
- **Employment:** full-time
- **Work type:** remote
- **Posted:** 2025-12-08

## Job description

The Synthetic Population Engineer uses cutting edge data science techniques to continuously improve the Epistemix synthetic population. A synthetic population is a statistically representative model of a population of real people and their environment, including personal attributes, social connections, and associations between people and places. These datasets empower customers to solve problems in domains where empirical data is unavailable due to legitimate concerns for personal privacy or where desired data simply does not exist. The Synthetic Population Engineer contributes to profitable growth by making the synthetic population more useful and accessible to customers, increasing adoption and utilization. Having a synthetic population that is continuously updated and improved over time is critical to building trust in the models and solutions built with our platform.

## About Epistemix

The most consequential decisions in public health, life sciences, insurance, and enterprise strategy share a common problem: they involve human behavior, network effects, and downstream effects that cannot be safely tested before action is taken. Traditional analytical techniques built on historical data were not built for this. Epistemix was. We build simulation and data-driven modeling tools that let leaders visualize how strategies will unfold across populations and systems before they commit resources. By clarifying which variables drive outcomes, where leverage exists, and how they interact, we help organizations move from uncertainty to conviction. Getting these decisions right means faster interventions, better-allocated resources, and measurable improvements in human and economic outcomes. We exist to make that possible. Our platform gives organizations access to realistic, high-resolution population data and the modeling infrastructure to run scenario planning at scale. Together, these capabilities let decision-makers stress-test strategies in a controlled environment before deploying them in the real world across healthcare, consumer industries, insurance, and government. We are approaching our Series B and actively building the team that will define what comes next.

## Responsibilities

- Identify and evaluate empirical datasets and use them to enrich the synthetic population to enable new use cases, including through adding new individual attributes and detailed social networks.
- Utilize simulation techniques, including ABMs, to project future demographic trends.
- Improve the geographical plausibility of synthetic environments, ensuring realistic placement of homes, workplaces, schools, and other points of interest (e.g., along roads, close to real world population centers).
- Expand the geographical region covered by the Epistemix synthetic population, with the goal of creating a fully integrated and consistent representation of the global population.
- Create visualizations for marketing and productizing synthetic populations.
- Develop innovative methods for supporting external users in augmenting Epistemix synthetic populations with their own proprietary data.
- Work with external vendors and marketplaces to expand the ecosystem of data providers that can be integrated with the synthetic population.
- Support the synthetic populations team in engaging with customer success, professional services, and engineering teams to understand project specific synthetic population requirements.

## Qualifications

- Proficient experience in:
- Using Python for data science applications.
- Working with relational databases such as PostgreSQL (additional database management experience preferred).
- Working with geospatial data.
- Working with simulation or machine learning models.
- Demonstrate empathy for users and decision makers by explaining how the synthetic population was created (e.g., which data sources and models were used) in an accessible way for all.
- Possessing the passion to build the standard for synthetic populations globally to improve decision making across social, health, economic, and environmental policies and advancing data science into more commercial applications.
- A PhD or master’s degree in Data Science or a relevant technical discipline such as Computer Science, Mathematics, Statistics, Epidemiology, or Public Health.
- Proven track record of success building data products and/or data marketplaces.
- Having a startup mentality with understanding the risks and the ability to flex across needs of an evolving team in a fast-paced environment.

## About Epistemix

## Company Overview
- **One-liner**: Epistemix provides an agent-based simulation platform that enables organizations to forecast population behavior, manage risk, and make data-driven decisions in low-information environments.
- **Entity Type**: Private (Post-Series A; raised $19.5M in total funding across 7 rounds)
- **Headquarters**: Pittsburgh, Pennsylvania, United States (with an office in the United Kingdom)
- **Founded**: 2018
- **Founders**: John Cordier (CEO)

## Core Business
- **Primary industry/industries**: Simulation Software, Population Modeling, Decision Intelligence, Public Health
- **Target customers**: Government agencies (public health), Global Corporations (CPG, healthcare, finance), and Research Organizations (B2B, Enterprise)
- **Mission or purpose statement**: Epistemix is building the tools to make sense of complex population dynamics to empower better decisions — replacing uncertainty with clarity and moving decision-making from guesswork to insight.

## Products & Services
- **[Populus]**: A population data platform that provides a statistically representative 1:1 synthetic population of a target market. Used for sizing Total Addressable Market (TAM), segmenting audiences, enriching existing data, and discovering patterns traditional analyses miss. (Data/API Platform)
- **[Polaris]**: A scenario planning platform that empowers organizations to test strategies, optimize decisions, and shorten decision cycles through simulation, AI, and inference. Users can ask "What If...?" to understand the impact of different scenarios (e.g., product launches, resource allocation, health benefit adoption). (SaaS Simulation Platform)
- **Custom Consulting / Modeling Services**: Epistemix partners with clients to build bespoke agent-based models for specific strategic challenges (e.g., disease spread, market saturation, political polarization). (Service)

## Market Standing
- **Total Funding**: $19.5M (across 7 rounds)
- **Latest Round (Seed/Series A mix)**:
    - Series A (2024-03-31): $5.0M from 3 investors
    - Venture Round (2022-02-11): $5.1M
    - Seed Round (2022-03-01): $5.0M from 4 investors
- **Notable Investors/Partners**: Not fully disclosed in public sources, but seed/Series A syndicate includes multiple unnamed institutional investors. Partners include leading public health agencies and global corporations.
- **Growth Signals**:
    - Headcount grew 15% YoY (16 employees as of mid-2025).
    - LinkedIn followers grew 30.2% over the past year.
    - Website traffic grew 281.6% year-over-year.
    - Actively hiring with 14 open positions (including AI Engineers, Data Scientists, and Backend Engineers).
    - Clients include major public health agencies and global CPG/healthcare firms.

## Competitive Advantages
- **Proprietary Synthetic Population Technology**: Epistemix builds statistically representative "digital twins" of entire populations (countries, cities, target demographics) without using real PII. This allows them to model behavior in environments where traditional data is sparse or unavailable.
- **Agent-Based Modeling (ABM) at Scale**: Unlike traditional statistical models, their ABM simulates the interactions of millions of individual "agents," capturing emergent behaviors (e.g., tipping points, market saturation, cultural movements) that aggregate models miss.
- **Academic-to-Commercial Bridge**: Born from academic research, the platform has been validated in high-stakes environments (e.g., pandemic response), providing a strong credibility moat.
- **High Switching Costs**: The platform integrates deeply into client planning workflows. Once an organization builds its decision-making process around Epistemix’s simulation outputs, the cost and risk of switching to a less sophisticated alternative are high.

## Strategic Focus
- **Product-Led Growth & Platformization**: Shifting from bespoke consulting to a self-service and scalable SaaS platform (Populus/Polaris).
- **Industry Expansion**: Moving beyond public health into CPG, financial services, and climate resilience.
- **AI Integration**: Leveraging AI and inference engines within the platform to accelerate scenario creation and improve prediction accuracy.
- **Talent Acquisition**: Bulking up engineering and data science teams (hiring for AI Engineers, Synthetic Population Engineers, and Senior Backend Engineers) to accelerate product development.

## Why Work Here
- **Mission-Driven**: Work on the "biggest challenges of our time" — pandemics, climate change, political polarization — by giving leaders the tools to make sense of complex dynamics.
- **Culture & Values**: Guided by values of **Empathy** (understanding users, constraints, motivations), **Clarity** (keeping things simple, being forthright), **Inspiration** ("checkers, not chess" — focus on long-term strategy), and **Grit** (sustained effort to win).
- **Technical Depth**: Strong emphasis on agent-based modeling, synthetic populations, and AI. Tech stack includes Python, TypeScript, Django, React, Postgres, Kubernetes, AWS, Terraform, and modern CI/CD tooling.
- **Growth Opportunity**: As a 16-person company growing rapidly (15% YoY headcount growth) with $19.5M in funding, new hires have significant ownership and impact over product direction.
- **Work Modes**: Primarily in-office presence (HQ in Pittsburgh, PA) with some flexible arrangements. The team culture emphasizes direct collaboration on complex modeling challenges.
