● Architectural Strategy: Define and evangelize the long-term roadmap for high-scale,
mission-critical distributed systems.
● Engineering Excellence: Lead architecture reviews ensuring designs align with
security, scalability, and cost-efficiency goals.
● System Design: Implement event sourcing and CQRS patterns; analyze the impact of
changes on complex data flows.
● Leadership & Mentorship: Guide junior engineers and drive a culture of continuous
learning and experimentation.
● Operational Maturity: Drive the adoption of advanced DevSecOps and SRE principles,
ensuring 24/7 application reliability and performance.
● Collaboration: Partner with Product, Data Science, and Account Management to
translate business requirements into robust technical stories.

● Distributed Systems: 4+ years of experience designing distributed, scalable
architectures.

Preferred Skills (The "Nice-to-Haves")

● Reactive Frameworks: Experience with Akka/Pekko (Cluster, Persistence, Projections,
and Serialization) is highly desirable but not required.
● Big Data: Exposure to Apache Spark and Spark SQL; experience tuning large-scale
Big Data applications.
