Data Engineer

Data Engineer (Graph Data Systems/Neo4j/Python/Entity Resolution) · Senior · Remote · LATAM

We are partnering with a fast-growing healthtech startup that is building
AI-native infrastructure for next-generation personalized and preventative healthcare
.

They are developing an all-in-one clinical data platform designed for a new era of medicinewhere fragmented, longitudinal, and multi-modal health data becomes real-time, actionable insights for clinicians and care teams.

This platform unifies records, labs, wearables, diagnostics, genomics, and lifestyle inputs into a single, coherent patient model. Early customers include leading functional, integrative, longevity, and concierge medicine clinics, helping shape the product from day one.

The mission:
turn complex health data into clarity and action
, laying the foundation for predictive personal health models, adaptive clinical intelligence, and digital health twins.

Senior Data Engineer (Graph-Based Data Systems)

This role is ideal for an engineer who has
strong experience with graph databases
and thrives in building complex, scalable data systems from the ground up. You will design the core graph architecture, data lineage systems, fuzzy matching engines, and ingestion frameworks that power the future of healthcare intelligence.

Core Responsibilities

Graph Data Architecture

• Design and implement the companys core
  graph database architecture
  (likely Neo4j).
• Create advanced graph models representing patients, biomarkers, protocols, events, and relationships across multi-modal data.
• Enable high-context queries such as
  "find patients with similar longitudinal patterns."

Data Normalization & Entity Resolution

• Build the entire normalization and deduplication engine.
• Implement
  fuzzy matching & entity resolution
  for unifying messy, multi-source health data.
• Establish rules, heuristics, confidence scores, and automated unification pipelines.

Metadata, Lineage & Provenance

• Design a transparent lineage layer where every data point tracks:
• source
• timestamp
• reliability
• transformation path
• confidence scoring
• Ensure full traceability from ingestion storage computation.

Time-Series & Longitudinal Data Systems

• Architect storage optimized for
  high-frequency time-series signals
  (CGM, wearables, diagnostics).
• Support long-term longitudinal analysis across patient lifecycles.

API Layer & Query Engine

• Build APIs enabling complex graph queries and multi-relationship traversal.
• Support both real-time and analytical access patterns.

Multi-Source Health Data Ingestion

• Design ingestion for:
• clinical records (EHRs)
• labs
• wearables
• lifestyle/behavioral inputs
• continuous monitoring devices
• advanced diagnostics and genomics
• Unify this data into a structured, high-quality canonical model.

Required Skills

Must-Haves

• Deep, hands-on experience with graph databases (Neo4j or similar).
• Strong graph-based and relational data modeling.
• Experience with
  fuzzy matching & entity resolution
  algorithms.
• Experience in
  metadata, lineage, and provenance
  systems.
• Time-series data architecture and longitudinal data design.
• API design for complex, multi-hop queries.
• Strong
  Python + SQL
  .
• Solid
  system design
  , especially around scalability and performance.

Nice-to-Haves

• Knowledge graphs or semantic data modeling.
• Built full data platforms end to end.
• Experience normalizing messy, multi-source data.
• Kafka, Pub/Sub, or other streaming frameworks.
• Exposure to healthcare data: FHIR, HL7.
• Experience with ML-driven feature extraction or enrichment.

What You Can Expect

• 100% remote
• Full contractor engagement
• High-impact role with ownership from day one
• Work alongside a world-class founding team in healthtech and AI
• Build foundational infrastructure for the next decade of healthcare
• Fast-moving, product-driven environment

Ideal Candidate

• Thrives in early-stage, high-ownership environments.
• Loves building complex systems from scratch.
• Enjoys deeply technical challenges with real-world impact.
• Believes in the power of data to transform healthcare.
