We are currently seeking a Data Migration Engineer to join a healthcare data migration project. You will extract, transform, and migrate patient and practice data from a wide range of Electronic Health Record (EHR) systems into a unified platform.

Align with key ethical principles, consistently demonstrating responsibility, confidentiality, and integrity;
Able to deliver under deadline pressure without cutting corners on quality.
Requirements
Strong programming skills, with hands-on experience in Node.js / JavaScript (ES Modules);
Confident, strong Linux user: command line, shell scripting (grep, sed, awk, find), ssh, permissions, and cron/scheduled tasks;
Proven experience with web scraping, API integration, and/or RPA, and the ability to pick the right data-acquisition approach per system: public APIs, unofficial/internal APIs, browser automation, HTML parsing, file exports, or RPA;
Solid experience with the core stack: MongoDB, axios, puppeteer, cheerio, and cookie/session handling (tough-cookie / http-cookie-agent);
Comfort parsing and normalizing many data formats - JSON, CSV, XML, HL7, CCDA, PDF, XLSX, and Access databases (csv-parse, fast-xml-parser, xlsx, mdb-reader, pdf-parse, officeparser, simple-hl7);
Schema definition and data validation with zod;
Familiarity with git, eslint + prettier, vitest, and Docker/docker compose;
Careful, secure handling of sensitive patient data - least privilege, and data protected in transit and at rest;
A track record of delivering on tight migration deadlines without compromising data accuracy.
Nice to Have
Prior experience with EHR / healthcare data systems;
Familiarity with HIPAA and healthcare data privacy regulations;
Experience reverse-engineering undocumented APIs;
Experience with additional headless-browser frameworks (e.g., Playwright).
As a Data Migration Engineer, You Will
Design and build data extraction pipelines from EHR systems, using whatever approach the source system demands;
Map and transform heterogeneous source data into standardized schemas;
Own the end-to-end migration for assigned practices, from raw export to validated import;
Write tests and validation checks to guarantee data completeness and accuracy;
Take ownership of your migration timeline, anticipate blockers early, and deliver on schedule;
Handle all patient data with care, confidentiality, and integrity, following the principle of least privilege;
Collaborate with the team to continuously improve extraction, mapping, and tooling.
What We Offer
You can fully realize your potential in a supportive environment where your experience is valued.
We believe in continuous learning and development - you'll have access to a library, weekly tech talks, and course compensation (including English classes);
If you love sharing knowledge, we'll fully support you!
