Job Description
Company Overview:
Blink Health is the fastest growing healthcare technology company that builds products to make prescriptions accessible and affordable to everybody. Our two primary products – BlinkRx and Quick Save – remove traditional roadblocks within the current prescription supply chain, resulting in better access to critical medications and improved health outcomes for patients.
BlinkRx is the world’s first pharma-to-patient cloud that offers a digital concierge service for patients who are prescribed branded medications. Patients benefit from transparent low prices, free home delivery, and world-class support on this first-of-its-kind centralized platform. With BlinkRx, never again will a patient show up at the pharmacy only to discover that they can’t afford their medication, their doctor needs to fill out a form for them, or the pharmacy doesn’t have the medication in stock.
We are a highly collaborative team of builders and operators who invent new ways of working in an industry that historically has resisted innovation. Join us!
About the Role
We are seeking a Principal Data Platform Engineer to define and evolve our real-time and batch data platform built on AWS and Databricks. This role owns the technical vision for how data is ingested, processed, stored, and served as trusted datasets, metrics, and APIs that power products, decisioning systems, machine learning use cases, and operational workflows.
As a Principal, you are a technical authority and force multiplier—deeply hands-on while setting architectural direction across streaming systems, lakehouse design, and data-serving layers. You will partner closely with engineering, analytics, and product teams (and occasionally data science partners) to simplify the platform, eliminate legacy patterns, and establish scalable, reliable foundations for real-time analytics and AI-enabled applications.
What You Will Do
Define and own the end-to-end data platform architecture, spanning streaming ingestion, lakehouse storage, and data/insight serving layers
Architect real-time streaming systems using AWS Kinesis and Spark Structured Streaming to support low-latency use cases including model-driven and decisioning workloads
Design stream-to-lakehouse convergence patterns that unify real-time and historical data with strong correctness guarantees required for analytics and ML use cases
Build and evolve data and metrics APIs that expose curated datasets for downstream applications and analytics including machine learning systems
Establish canonical event schemas and data contracts to support event-driven and API-based consumption by analytics and ML workloads
Make deep technical decisions across AWS infrastructure (Kinesis, S3, IAM, networking) and Databricks internals (clusters, jobs, Delta Lake, performance tuning)
Drive platform modernization, retiring legacy tools and patterns in favor of simpler, lakehouse-first designs
Set standards for high-performance SQL and Spark workloads, optimizing for cost, latency, and scale while supporting data freshness and correctness expectations common to ML pipelines
Lead complex platform initiatives from architecture through production delivery and ongoing reliability
Provide technical leadership and mentorship, shaping best practices for platform design, data quality, and operability
Qualifications
10+ years of deep expertise in real-time and distributed data systems, including AWS Kinesis and Spark Structured Streaming
Strong command of Databricks on AWS (Delta Lake, clusters, jobs) and core AWS services (S3, IAM, networking)
Proven experience designing data-serving architectures and APIs for analytics and metrics consumed by downstream applications and ML workflows
Advanced Python and SQL skills for building scalable, high-performance data pipelines
Demonstrated ability to design idempotent, replayable, and observable data platforms at scale suitable for analytics and machine learning use cases
Why Join Us:
It is rare to have a company that both deeply impacts its customers and is able to provide its services across a massive population. At Blink, we have a huge impact on people when they are most vulnerable: at the intersection of their healthcare and finances. We are also the fastest growing healthcare company in the country and are driving that impact across millions of new patients every year. Our business model not only helps people, but drives economics that allow us to build a generational company. We are a relentlessly learning, constantly curious, and aggressively collaborative cross-functional team dedicated to inventing new ways to improve the lives of our customers.
We are an equal opportunity employer and value diversity of all kinds. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
