Remote - Principal Architect (.NET​/Platform Modernization Architect), W2

Myticas's direct client, is seeking a Principal Architect (.NET / Platform Modernization Architect) for a 100% Remote contract position.

Location: 100% REMOTE

ONLY W2. This is Contract-to-Hire opportunity.

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.

• 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 datafeeds,
  • 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.

• 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.

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