Senior Software Engineer - Next Best Action

Become a part of our caring community and help us put health first

We are searching for a Senior Software Engineer to architect, develop, and maintain action and policy platforms that enable real-time, personalized decisioning across both digital and assisted channels. These platforms determine which actions can be taken, contextual variations, and the conditions under which they are permitted, leveraging structured metadata, deterministic rule engines, and resilient backend services.

This position demands expertise in microservices development, advanced database schema design, and seamless integration of enterprise rules systems. You will be responsible for designing robust, scalable data models, building high-throughput, low-latency services, and integrating policy evaluation engines. Additionally, you will employ AI-assisted and agentic engineering practices to enhance productivity, ensure correctness, and streamline long-term maintainability.

Key Responsibilities

Microservices & Backend Engineering

• Architect, implement, and operate microservices that deliver:
• Action and variant metadata
• Context-aware policy and eligibility evaluation
• Versioned, read-optimized APIs for high-performance runtime consumption
• Guarantee that services are:
• Highly available, with low latency
• Horizontally scalable for increased demand
• Backward compatible to support safe evolution and upgrades
• Apply industry best practices for API design, schema evolution, service isolation, and secure integration.

Database & Schema Design

• Design, deploy, and maintain resilient database schemas to support:
• Comprehensive action and variant catalogs
• Versioning, lifecycle management, and effective dating
• Rule bindings and complex metadata relationships
• Select and operate appropriate data stores (relational, document, key-value) tailored to workload and scalability requirements.
• Implement and monitor:
• Schema migration and backward compatibility strategies
• Indexing and query optimization for performance
• Data integrity, consistency, and reliability
• Auditability and traceability for compliance and governance

Rules & Policy Engine Integration

• Integrate and manage enterprise-grade rules engines to support:
• Eligibility, constraints, and business policies
• Suppression, cooldowns, exclusions, and other operational guardrails
• Policy-driven allow/deny logic
• Work with technologies such as Drools (DRL/DMN), IBM ODM, DMN-based services, OPA/Rego, or similar.
• Ensure rule execution is deterministic, versioned, stateless, and free from unintended side effects.

AI-Assisted & Agentic Engineering

• Utilize AI-powered and agentic tools to:
• Generate and refactor database schemas and service logic
• Streamline rule authoring, validation, and ongoing refactoring
• Detect and address conflicting or redundant rules early in the development cycle
• Automatically produce comprehensive test cases and explore edge scenarios
• Apply AI responsibly to reduce manual effort while safeguarding clarity, correctness, and strong governance.

Testing, Reliability & Governance

• Develop automated tests for:
• Database migrations and schema changes
• Service-level contracts and API backward compatibility
• Rules behavior, precedence, and edge cases
• Ensure platforms are fully observable and resilient, featuring:
• Structured logging, metrics, and alerting
• Clear error handling, fallback strategies, and robust incident management
• Support audit and compliance requirements through traceable and reproducible system behavior

Collaboration & Technical Leadership

• Work closely with platform, data, and machine learning teams to maintain clean integration points and shared standards.
• Participate actively in architecture and design reviews to uphold platform quality.
• Mentor junior engineers and contribute to technical standards and best practices.

Use your skills to make an impact

Required Qualifications

• Minimum 6 years of experience in backend or platform engineering
• Proven ability to build:
• Microservices and REST/gRPC APIs
• Database-backed systems with complex, evolving schemas
• Deterministic rules or policy-driven platforms
• Direct experience integrating enterprise rules engines (Drools, ODM, DMN, OPA, or similar)
• Strong proficiency in Java and/or Python
• Experience using AI-assisted development tools for increased productivity and accuracy

Preferred Qualifications

• Experience designing versioned schemas and backward-compatible APIs
• Knowledge of high-throughput, low-latency architectures
• Familiarity with systems requiring explainability, auditability, and strong compliance
• Background in regulated or high-compliance domains

Success Metrics

• Action and policy services are stable, performant, and adaptable
• Database schemas facilitate correctness, efficiency, and full audit trails
• Rules execution is deterministic, transparent, and trusted by stakeholders
• AI-assisted tooling reduces development and maintenance cycles
• Platform is widely trusted as a reliable source of truth for downstream consumers
