We are seeking a highly motivated Senior Data Engineer to join an enterprise technology team working on modern, AI-enabled data platforms. This role is ideal for an experienced engineer who enjoys building scalable data solutions, collaborating with cross-functional teams, and driving engineering best practices in a cloud-native environment.

You will work on enterprise-grade applications and data processing solutions using modern technologies including Azure, Databricks, Python, and microservices.

• Build efficient and reliable data processing and transformation pipelines.
• Write clean, well-documented, and maintainable Python code.
• Optimize applications for performance, scalability, and efficient data handling.
• Collaborate with engineering, product, and business stakeholders to deliver high-quality solutions.
• Troubleshoot and resolve technical issues to ensure system reliability.
• Create and maintain technical documentation, workflows, and development standards.
• Communicate effectively with internal teams and external stakeholders while supporting project delivery.

Required Qualifications

• 5+ years of professional software engineering or data engineering experience.
• Strong experience with Apache Spark using Databricks and/or Azure Synapse/Fabric.
• Advanced Python programming skills, including data manipulation with Pandas, Polars, or similar libraries.
• Experience working with Parquet, Delta Tables, and other columnar storage formats.

• Experience designing scalable applications using microservices architecture.
• Strong analytical, troubleshooting, and problem-solving skills.
• Excellent organizational, communication, and time management abilities.
• Ability to work independently while collaborating effectively within distributed teams.

Preferred Qualifications

• Experience with Microsoft Azure cloud services, including Data Lake, Blob Storage, Service Bus, Redis, and related services.
• Familiarity with FastAPI.
• Experience with Docker and Kubernetes.
• Exposure to modern AI technologies, RAG pipelines, or large language model (LLM) applications is a plus.

Technology Stack

• .NET 8 / ASP.NET Core
• Microservices Architecture
• GitHub Enterprise
• Angular
• Docker & Kubernetes
• AI/LLM technologies (LangChain, LangGraph, RAG)

You'll own the interface that turns raw medical data into something a clinic manager can actually act on. Today most of that data lives in exports, internal reports and half-built screens - the product works, but the front-end has grown faster than it was designed. Your job is to build and clean up the part users touch: dashboards, patient and claims tables, filters, charts, reports.

This is a hands-on product role, not a lead role. You own your tasks end to end, architecture decisions are made together with the CTO.

About the company
A European product company building a data and analytics platform for the healthcare sector - clinics, medical networks and insurers use it to see what is happening with their patients, costs and operations in one place.

• On the market since 2022
• Team of 11-50 people
• Fully remote engineering team [to be confirmed]
• Product company, no outsourcing or client rotation

What you'll do

• Build and maintain front-end features of the platform in React + TypeScript
• Develop data-heavy UI: dashboards, charts, large tables, filters, export and reporting screens
• Integrate the front-end with backend APIs, handle async data, caching and error states 
• Turn Figma designs into clean, reusable components
• Use AI coding tools (Claude Code and similar) as part of your daily workflow
• Cover your code with tests and take part in code review
• Work directly with the CTO and the designer to clarify requirements before you build
• Take a task from description to production and keep it stable afterwards

Who we're looking for
Must have:

• 3-5 years of commercial experience with React
• Strong JavaScript and TypeScript
• Practical experience with state and server data management (React Query / Redux Toolkit / Zustand - any of them)
• Experience integrating REST APIs and building complex forms and data tables
• Experience with charts and data visualization libraries (Recharts, Chart.js, D3-based, or similar)
• Daily use of AI coding assistants in real work, with hands-on experience of Claude Code
• English at B2+ - you will talk to the CTO and the team directly, without a translator
• Ability to run your own tasks without daily check-ins, and to ask questions early when something is unclear

Nice to have:

• Experience connecting AI tools to external systems
• Figma-to-code integrations or similar
• Background in healthcare, medtech or fintech - any domain with strict data rules (GDPR, HIPAA, FHIR/HL7)
• Next.js, testing (Jest, React Testing Library, Playwright)
• Experience working with design systems

Soft skills:

• Ownership - the team is small, and nobody will chase you for status updates
• Clear written communication - most of the work happens async, across time zones
• Attention to data correctness - a wrong number on a medical dashboard is not a cosmetic bug

Conditions

• Remote, flexible working hours
• 29 days of PTO (18 working days per year plus all national holidays)
  10 paid sick days
• Free English classes with native speakers or Ukrainian teachers
• People-first management, minimal bureaucracy

• Embed directly into a client squad as a hands-on Individual Contributor (not a coaching/managerial role).

Must-Have Skills:

• Experience with dbt.
• Strong SQL and data-modelling skills.
• Experience building and maintaining business-critical data models for credit, payments, and fraud/AML reporting.
• BigQuery — the client's stated primary data warehouse for data platform and analytics workloads.
