Senior Data Engineer

Data Engineer Metriport is an open-source data intelligence platform that helps healthcare organizations access and exchange patient data in real-time. We integrate with all major US healthcare IT systems and tap into comprehensive medical data for 300+ million individuals. We're looking for a data engineer who can operate at a Senior level: You've built and scaled data pipelines and systems, with hands-on experience across the ecosystem — distributed processing, lakehouses, warehouses, streaming, orchestration. You know when each is (and isn't) the right tool for the job, and people usually come to you for guidance on how to move, transform, and serve data reliably. You fully own your work — technical decisions, delivery, results — and you level up the engineers around you through code reviews, pairing, and guidance. Multiplying the team's output energizes you as much as shipping your own. You're entrepreneurial-minded with an olympian-level work ethic (about half our engineering team are former founders). You understand data reliability, quality, and governance as first-class parts of delivery. You care about delivering value to customers, not about what frilly new tech is under the hood. When someone scopes a project for 3 weeks, you ask "why can't it be done in 3 days?" — and you help others develop that same instinct. You're a hacker at heart, with a good sense of which rules should, and shouldn't, be broken. We ingest clinical data for millions of patients from external healthcare sources, with continuous updates for a growing subset of those patients. You'll be a catalyst to scale the data platform that powers our product — and ship it to customers fast. Day to day, that looks like: Raising the technical bar for our data platform: building on and improving our warehouse, data lake, and ETL/ELT architecture so it scales with patient and customer growth, and helping evaluate the right tools (batch and streaming processing, table formats, orchestration, query engines). Driving data projects end-to-end: writing Design Documents, shipping v0's quickly, and iterating to v1 and beyond. Supporting AI/ML efforts - making sure the AI Engineers have the data they need. Multiplying the team: mentoring engineers on data fundamentals, reviewing designs and PRs, and judging when to invest in quality vs. ship fast. Participating in bi-weekly sprint planning and retros, joining our daily 30-min remote stand-up at 7:30am PST (our only mandatory meeting), and taking part in the on-call rotation. Example projects you could own: Scaling our patient data consolidation pipeline (deduplication, normalization, hydration) to handle 100x today's volume without 100x the cost. Building pipelines that deliver clinical data directly into customers' data warehouses, reliably and at scale. Building the ingestion path for customers pushing large volumes of their own data into the platform. Building document-processing pipelines that extract structured data from PDFs, images, and free text to feed ML models. Requirements: 6+ years of engineering experience, with a heavy lean towards data engineering — building, maintaining, and scaling pipelines processing terabytes of data and millions of events a day. Experience across the data stack — ingestion, storage, processing, warehousing, serving — and an understanding of the tradeoffs (cost, latency, correctness, operability) at each layer. Experience with modern, cloud-native data stacks: e.g., Spark, open table formats (Parquet, Iceberg, Delta) on S3, and warehouses (Snowflake, BigQuery, Redshift). Strong software engineering fundamentals — you write production code (we're a TypeScript shop, with Python in data/ML workflows), not just orchestration configs. Experience mentoring or guiding other engineers — through code reviews, pairing, design feedback, or onboarding. Located in San Francisco / Bay Area, or willing to relocate. Bonus: Experience with streaming systems (Kafka, Kinesis), dbt, or orchestration tooling (Airflow, Dagster). Experience building or supporting ML/data science workflows (feature pipelines, model inputs/outputs, unstructured data extraction). Healthcare standards/technologies: FHIR, HIE, IHE, EHR/EMR, NPI, TEFCA, ADT, HL7, HEDIS, RAF, SNOMED, LOINC, ICD-10, etc. Benefits: Competitive equity + compensation package Full family Platinum health insurance, dental, and vision coverage 401(k) retirement plan + matching Flexible work from home or in-office Healthy lunches are complimentary when working in-office (and breakfast + dinners as needed) Quarterly company off-sites with the team MacBook provided by us Unlimited PTO (we work hard, but trust you to take time you need to be at your best) Core business logic in Node.js and TypeScript, with Python in data and ML workflows. AWS across the board (ECS, Lambda, SQS, SNS, Batch, etc.), infrastructure as code with CDK. Data lives in S3, PostgreSQL/Aurora, DynamoDB, Snowflake, and our FHIR server — with Athena for querying S3 and SageMaker for ML. Our data platform is still early: you'll shape what we adopt next, picking the best tool for the job rather than the trendiest one.
