Note: The job is a remote job and is open to candidates in USA. DrFirst is a healthcare IT company that improves healthcare workflows through intelligent medication management and prescription access solutions. The Senior Data Scientist will lead end-to-end AI, machine learning, and NLP initiatives, develop and productionize LLM-powered solutions and data pipelines, ensure healthcare compliance and model quality, and provide technical leadership and mentorship.
Responsibilities
- Own AI, ML, and NLP initiatives end to end, from problem framing through model development, validation, deployment, monitoring, and long term maintenance in production
- Apply LLMs to automate complex, high volume workflows. Partner with software architects and engineering to deliver solutions that meet strict platform latency and throughput requirements across millions of transactions, balancing accuracy, response time, and inference cost through model selection, caching, and prompt design
- Define what good looks like. Build evaluation datasets and automated eval pipelines for LLM and ML systems, measure quality and error rates on clinical and financial content, and catch regressions when prompts, models, or data change
- Build and own the data foundations behind these models, including production grade pipelines and feature datasets sourced from our PostgreSQL transactional systems and Redshift warehouse, with attention to data quality, lineage, and reliability
- Partner with clinicians, pharmacists, and other domain experts to define ground truth, adjudicate edge cases, and validate that model behavior holds up against real clinical workflows
- Ensure solutions are accurate, robust, and compliant with healthcare regulations including HIPAA, with appropriate handling of PHI and monitoring for bias, safety, and performance drift
- Act as the technical lead on projects. Set direction, define approach, establish best practices, and influence technical strategy on complex, high ambiguity problems
- Coach and mentor data scientists through pairing, design and code reviews, and constructive feedback. Contribute to hiring by interviewing and helping raise the technical bar of the team
- Communicate complex analytical findings to technical and non-technical audiences, including executive management, through clear presentations, reports, and visualizations
Skills
- Master's or Ph.D. in Computer Science, Data Science, Statistics, Mathematics, or a related quantitative field
- 5+ years of professional experience in data science, machine learning, and NLP, with a track record of delivering models into production
- Advanced proficiency in Python and SQL
- Pipeline development and orchestration. Hands on experience building ELT and ETL workflows with tools such as dbt, Airflow, and AWS data services (Glue, DMS, Lambda, S3), with attention to incremental loads, idempotency, data quality testing, and documentation and lineage
- Strong software engineering fundamentals, including tested, modular, production quality Python, Git based workflows and code review, containerization (Docker), and CI/CD
- Experience productionizing and monitoring models on AWS, including model registry, CI/CD for ML, versioning, and post deployment monitoring, with tools such as SageMaker and MLflow
- Experience building and evaluating LLM powered applications, for example Claude via Amazon Bedrock, including prompt design, retrieval and RAG pipelines, and systematic evaluation of output quality
- Proven ability to scope ambiguous problems and deliver solutions end to end with minimal supervision
- Demonstrated ability to lead projects and coach or mentor other data scientists, guiding technical decisions and elevating team output
- Excellent problem solving and communication skills, and the ability to thrive in a fast paced environment
- 90% Desk work
- 10% Remote travel to client sites, conferences, or internal team meetings
- Experience in the healthcare or insurance industry
- Healthcare data literacy across FHIR, HL7v2, and X12, and clinical vocabularies including RxNorm, NDC, ICD-10, and SNOMED
- Demonstrated experience designing and maintaining production data pipelines. This includes modeling data for an analytical warehouse (Amazon Redshift or a comparable columnar MPP platform), extracting from transactional systems (PostgreSQL), and writing performant SQL against large tables, including the ability to read a query plan and fix a slow query rather than escalate it
- Comfortable packaging and deploying work in containers (Docker) and deploying models to cloud managed serving infrastructure such as SageMaker endpoints, ECS, or Lambda. Familiarity with Kubernetes is a plus
Benefits
- Eligible for a Discretionary Performance-based bonus
- Medical, dental, and vision insurance
- 401K eligible after 3 months of employment, with 50% company match up to first 5% of salary contributed to the plan with a 3-year vesting schedule
