Job Summary

We are seeking a Senior Technologist / Principal Architect to provide hands-on technical leadership as a mature healthcare analytics product evolves into a scalable platform. The initial focus for this role will be the incremental modernization of a legacy Oracle/PL/SQL based drug diversion detection system that processes hundreds of millions of records per tenant, followed by broader platform responsibilities as the product expands.

A core requirement of this role is defining and executing a modernization strategy that moves business logic and expensive processing out of the database layer and into application and platform-level compute, enabling improved scalability, flexibility, testability, and long-term platform evolution.

  • Location: Telecommute
  • Job Type: Contract
  • Salary: $79 - $89 per hour
  • Work Hours: 8am to 6pm
  • Education: Bachelors

Responsibilities

  • Lead the incremental modernization of a large, Oracle-centric system by extracting business logic and computationally intensive processing from PL/SQL into application and platform-level components, implemented using modern languages and frameworks (e.g., .NET/C#).
  • Design architectures that treat the database primarily as durable storage and efficient data access, while executing complex rules, detection logic, enrichment, and aggregation outside the database.
  • Define processing strategies that may include in-process, distributed, stateful, or partitioned execution models, selected based on workload characteristics (batch, near real-time, scale, and data volume).
  • Define and evolve the target architecture and technology stack, prioritizing open-source ecosystems and vendor-neutral patterns.
  • Design solutions capable of processing hundreds of millions of records across tenants, with attention to throughput, scalability, data isolation, and cost efficiency.
  • Establish migration strategies that enable parallel execution, parity validation, and safe incremental cutover as logic is moved out of the database.
  • Provide technical leadership as the product expands to integrate:
    • New clinical and operational data feeds
    • Modular services and APIs
    • Authentication and authorization capabilities
    • Internal and external integrations
  • Shape architectural standards for data ingestion, batch and near real-time processing, service boundaries, and API design.
  • Ensure systems are scalable, observable, reliable, and auditable, appropriate for regulated healthcare environments.
  • Remain hands-on, contributing to design and code while mentoring engineers and influencing technical direction across teams.

Qualifications

Skills and Experience

  • 5-7 years of experience
  • Health industry experience is a must-have
  • Significant experience modernizing legacy, data-intensive systems operating at scale.
  • Demonstrated success decoupling business logic and processing from relational databases and re-implementing it in application or platform-level execution environments.
  • Strong proficiency in C#/.NET or similar modern, multi-paradigm languages, with emphasis on modularity and testability.
  • Deep understanding of SQL and relational databases, including performance tuning and making informed decisions about what belongs in the database versus outside it.
  • Experience designing systems that handle large-volume, multi-tenant data using batch, micro-batch, or near real-time processing approaches.
  • Proven ability to define and execute incremental modernization strategies without disrupting production systems.
  • Experience guiding systems as they evolve from product to platform, supporting multiple integrations and consumers.
  • Strong communication skills and ability to influence technical and non-technical stakeholders.

Education

  • Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
  • Advanced degree is a plus but not required.
