Specializing in industries such as healthcare, automotive, insurance, and finance, our powerful data/AI insights tools inform the creation of compliant content at scale. We enable our customers to harness their data and streamline the creation of localized, personalized content.

About The Role

We're looking for a Senior Data Scientist to take a leading role in building the AI that powers Constellation. You'll ship production models—generative AI, autonomous agents, and predictive models for churn, LTV, and pricing— while mentoring a growing team and shaping our technical standards. If you want your work to reach real users in regulated industries like automotive and life sciences (not sit in a notebook), this is that role.

 

What You’ll Do

  • Lead AI/ML Initiatives: Architect, prototype, and productionize ML models, including generative AI, recommendation systems, and domain-specific agents tailored to marketing, regulatory compliance, and creative workflows.
  • Drive Agentic AI Capabilities: Build agent-based systems that reason, retrieve, validate, and act autonomously, supporting prompt chaining, tool usage, and evaluation feedback loops.
  • Mentor & Scale the Team: Coach junior and mid-level data scientists and engineers, review code, drive standards, and help shape a culture of high performance, curiosity, and inclusivity.
  • Collaborate Cross-Functionally: Work closely with Product, Engineering, Design, and GTM teams to integrate intelligent systems into customer-facing features and internal tooling.
  • Model Business-Critical Outcomes: Develop models for customer LTV, churn, content efficacy, user engagement, and pricing optimizations, leveraging both structured and unstructured data.
  • Own the ML Stack: Contribute to architecture decisions on model lifecycle management, pipelines, monitoring, and experiment tracking using modern tooling like MLflow, SageMaker, or Vertex AI.
  • Drive Applied Research: Stay on top of advances in transformers, large language models, retrieval-augmented generation, and probabilistic programming—and bring these innovations to production.

What We’re Looking For

  • 8+ years of experience in data science, ML engineering, or applied AI, with a track record of shipping models in production.
  • Deep experience with Python (Pandas, NumPy, Scikit-learn) and modern ML/DL libraries (PyTorch, TensorFlow, Hugging Face, LangChain).
  • Strong command of SQL and data modeling in cloud warehouses (e.g., Snowflake, BigQuery, Redshift).
  • Experience building systems using AWS (Lambda, SageMaker, EC2, Batch, S3) or similar cloud platforms.
  • Solid understanding of ETL/data pipelines and orchestration tools (e.g., Airflow).
  • Experience with agent-based architectures, LLMs, and real-world generative AI applications (NLP, content synthesis, summarization, retrieval).
  • Familiarity with automotive or life sciences data domains is a strong plus—whether in marketing analytics, medical devices, vehicle inventory intelligence, or regulatory content.
  • Outstanding communication and mentorship skills, with a collaborative mindset and a passion for helping others grow.

Bonus Experience

  • Experience with probabilistic modeling (e.g., PyMC3, Stan).
  • Familiarity with graph databases (e.g., Neo4j) and modeling network effects.
  • Prior exposure to recommendation engines, survival models, or multi-touch attribution.
  • Experience with deploying and evaluating LLMs, retrieval pipelines, or autonomous AI agents in production.
  • Exposure to Looker, Tableau, or similar BI platforms.

Why Constellation?

  • Work on real-world AI systems that impact regulated, high-stakes industries.
  • Collaborate with a team of ambitious, principled builders who care about quality, ethics, and impact.
  • Join a design-forward organization with strong product leadership and a rapidly growing client base.
  • Enjoy flexibility, autonomy, and opportunities to lead across the stack.

 

Compensation

NY Pay Range: $170,000 – $200,000

Final package commensurate with experience. Includes base salary, equity options, and benefits.

Constellation is committed to diversity, inclusion, and equal opportunity. If you require accommodation during the interview process, please let us know.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
