    Role Description
    The Senior Backend Engineer will lead the design and implementation of high-scale, serverless backend services using AWS, Python, Relational and NoSQL database, and modern architectural designs. You’ll own systems end-to-end, from design, development, and testing, through deployment, monitoring, and ongoing improvements. You will collaborate with engineering, analytics, product, and operations teams to build data pipelines, APIs, event-driven workflows, and durable processing engines that are foundational to delivering an exceptional, predictable healthcare experience.

    Responsibilities
    Architecture and System Design
    • Design and build large-scale, resilient, serverless systems using AWS Lambda, API Gateway, SQS, SNS, DynamoDB, Step Functions, EventBridge, and Kafka.
    • Architect durable, fault-tolerant workflows for claims processing, episode generation, eligibility updates, communication engines, and other core healthcare processes.
    • Create and evolve backend APIs for both B2C (member portal) and B2B (payer, employer, provider) integrations.
    Engineering and Implementation
     

    • Develop high-quality backend services in Python, following strict test-driven development (TDD) practices.
    • Build clean, well-structured codebases emphasizing maintainability, testability, reliability, and scalability.
    • Implement secure data flows and storage patterns aligned with HIPAA and healthcare compliance best practices.

     Data and Healthcare Standards

    • Partner with Analytics and Data Engineering to ensure data accuracy, consistency, and fidelity.
    Operational Excellence
     

    • Own systems end to end: development, testing, deployment, monitoring, and iteration.
    • Build and maintain CI/CD pipelines, infrastructure-as-code, and observability dashboards.
    • Continuously improve reliability through canaries, alarms, automated rollback, and well-designed SLOs.
    Collaboration and Leadership
     

    • Drive cross-functional architectural discussions and propose scalable, long-term solutions.
    • Mentor and hire engineers, raising the bar for engineering culture, coding standards, and system design thinking.
    • Work closely with product to refine requirements, define technical specs, and deliver high-value features.
    Qualifications
    • 7+ years of backend engineering experience, with a proven track record of shipping and operating production-grade systems.
    • Expert-level proficiency in AWS serverless, including Lambda, DynamoDB, API Gateway, Step Functions, Kafka/SQS, and event-driven architectures.
    • Strong Python engineering fundamentals, including TDD, dependency injection, modular code, and clean design patterns.
    • Deep understanding of high-scale system design, distributed computing, data modeling, fault tolerance, and observability.
    • Experience building B2C and B2B systems that serve thousands of users and millions of transactions.
    • Proficiency with PostgreSQL, DynamoDB, RDS, Kafka, caching strategies, and database schema design.
    • Strong experience building scalable, public-facing RESTful APIs.
    • Strong ownership mindset and a passion for delivering high-quality, reliable systems from design to production.
    • Experience collaborating with SecOps, DevOps, and analytics teams, with comfort using GitHub Actions, IaC, and automated pipelines.
    • Excellent verbal and written communication skills and cross-functional collaboration abilities.
    • Bonus: Experience with healthcare EDI standards (837/834), payer systems, claims processing, HIPAA compliance, or health-tech domain work.
    Compensation: $70.00 - $80.00 per hour
