This is a senior hands-on position. The developer will work with architects, Technical Business Analysts, QA and business teams to modernize one system, workflow or business area at a time without disrupting operations.

Key Responsibilities

• Design and build domain-based services for critical healthcare and laboratory capabilities.

• Modernize legacy applications and workflows while protecting business continuity.

• Reduce tight coupling and direct dependence on shared databases.

• Build independently deployable services with clear ownership and well-defined interfaces.

• Analyze legacy code, database dependencies, data flows and hidden business rules.

• Move hard-coded rules into governed, testable and reusable capabilities.

• Establish clear ownership for data, services and business decisions.

• Create secure APIs and event-driven integrations where appropriate.

• Reduce duplicate data, manual reconciliation and unnecessary copies of sensitive information.

• Plan and execute gradual migrations, parallel validation and controlled cutovers.

• Implement role-based access, audit logging, monitoring, performance controls and secure coding practices.

• Write automated tests and participate in design reviews, code reviews and production support.

• Create technical documentation and mentor engineers in modern engineering practices.

• Use AI-assisted tools for analysis, coding, testing and documentation while validating output and protecting sensitive data.

Required Qualifications

• Bachelor’s degree in Computer Science, Engineering or a related field, or equivalent experience.

• Strong collaboration with architects, analysts, QA and business stakeholders.

Preferred Qualifications

• Experience in healthcare, diagnostics, genomics or laboratory operations.

• Experience applying domain-driven design and the strangler modernization pattern.

• Knowledge of API versioning, event or message patterns, retries, idempotency and recovery.

• Experience moving from shared-database architectures to owned services and data domains.

• Knowledge of authentication, role-based access, audit logging and observability.

• Experience with containers, cloud platforms and performance engineering.

• Experience modernizing regulated systems through gradual migration and controlled cutover.
