Senior Scalability Engineer - Streaming & Realtime Systems

Judi Health is an enterprise health technology company providing a comprehensive suite of solutions for employers and health plans. They are seeking a Senior Scalability Engineer focused on streaming and realtime systems to own the architecture and expansion of their streaming data infrastructure while collaborating closely with clients and cross-functional teams.

Responsibilities:

• Own streaming infrastructure: Design, implement, and expand WAL-based replication systems that process database changes through Kinesis to Snowflake and Redshift, handling millions of records while maintaining strict ordering and delivery guarantees
• Build CDC systems: Architect and implement change data capture infrastructure for cross-platform data synchronization, enabling realtime analytics and event-driven workflows across the organization
• Develop shared libraries: Create reusable Kinesis/SNS consumer patterns and libraries used across multiple teams, establishing best practices for event processing, error handling, and observability
• Partner with product teams: Work directly with teams to design and implement realtime data processing solutions tailored to their business needs, providing technical guidance and hands-on support
• Ensure data reliability: Implement exactly-once processing semantics, dead letter queues, retry strategies, and monitoring to guarantee data integrity across streaming pipelines
• Build observability: Develop monitoring, alerting, and dashboards for streaming pipelines to track throughput, lag, data quality issues, and system health using the LGTM stack
• Demonstrate technical leadership: Mentor engineers on streaming architecture patterns, lead design reviews for event-driven systems, and represent the Scalability team in cross-functional planning
• Make strong architectural choices through careful evaluation and prior experience with distributed systems
• Responsible for adherence to the Capital Rx Code of Conduct, including reporting of noncompliance

Requirements:

• 10+ years of software engineering experience with demonstrated progression into technical leadership roles
• 3+ years of experience leading technical initiatives, architecting distributed systems, or serving as a subject matter expert on streaming infrastructure
• Strong expertise in Python (Flask/SQLAlchemy) for production applications
• Deep PostgreSQL knowledge: Understanding of write-ahead logs, replication, logical decoding, and change data capture mechanisms
• Production streaming experience: Proven track record building and operating high-throughput streaming systems using Kinesis, Kafka, or similar event streaming platforms
• Distributed systems expertise: Strong understanding of ordering guarantees, exactly-once semantics, partition strategies, backpressure handling, and fault tolerance patterns
• AWS experience: Production experience with Kinesis, S3, SNS/SQS, Lambda, ECS, and data pipeline orchestration
• Data warehouse knowledge: Experience loading data into Redshift, Snowflake, or similar analytical databases
• Systems thinking: Ability to design resilient, observable streaming architectures that balance throughput, latency, and reliability
• Collaboration and communication: Strong written and verbal communication skills with ability to work autonomously while driving proactive collaboration in a remote environment
• Rust development experience or strong interest in learning Rust for high-performance systems
• Infrastructure as code: Experience with Terraform or similar IaC tools for managing cloud infrastructure
• Observability tools: Hands-on experience with Grafana, Prometheus, Loki, or similar monitoring/alerting platforms
• Event-driven architectures: Background designing event sourcing, CQRS, or other event-driven patterns
• Previous Pharmacy Benefits Manager (PBM) or healthcare technology experience
