Role Overview
We are seeking a Principal Engineer to lead a critical refactoring initiative, migrating our existing platform to an in-memory database architecture. You will play a pivotal role in ensuring scalability, performance, and reliability across our technology stack.
Main Responsibilities
* Lead the design and refactor of the core platform to leverage an in-memory database solution, with emphasis on GemFire or equivalent distributed caching/data grid technologies.
* Partner with product and architecture teams to define scalability, performance, and quality goals aligned to RxSense business growth.
* Build and optimize data models, query performance, and caching strategies for mission-critical systems.
* Drive a test-first, quality-driven approach to engineering to improve release confidence, enhance date certainty, and reduce defects.
* Champion initiatives that reduce time to market while improving system reliability and lowering long-term engineering effort.
* Provide technical leadership and mentorship across engineering teams in best practices for distributed systems and high-performance data processing.
* Contribute hands-on to application development, with emphasis on Python for automation, integration, and backend logic.
* Collaborate with teams using Java and .NET/C# to ensure seamless migration and interoperability across the platform.
* Drive code reviews, design reviews, and architecture discussions to maintain engineering excellence.
* Champion the RxSense engineering culture of innovation, reliability, and continuous improvement.
Knowledge, Skills, and Experience
* 10+ years of software engineering experience, with at least 5+ years in distributed systems, in-memory data grids, or high-performance databases.
* Experience designing and implementing scalable architectures in a regulated or mission-critical environment.
* Strong understanding of data consistency, replication, fault tolerance, and distributed computing principles.
* Hands-on leadership: ability to set direction, mentor teams, and still roll up sleeves for deep technical work.
* Experience with GemFire (strongly preferred) or similar platforms (Hazelcast, Redis Enterprise, Coherence, Ignite).
* Proficiency with Java and/or .NET/C#, particularly in enterprise environments.
* Proven expertise in Python (backend, data pipelines, automation, or distributed applications).
* Background in healthcare, PBM, or other regulated industries a plus.
* Familiarity with CI/CD pipelines, cloud infrastructure (AWS), and containerized environments (Docker/Kubernetes).
* Prior success driving large-scale platform refactors or migrations.
