Principal Software Engineer, Platform Engineering

8–12 years of experience designing and building backend or platform software for enterprise SaaS or cloud-native applications, with a primary focus on application-layer engineering, not infrastructure operations.

Deep expertise in Java, Spring Boot, Hibernate, MySQL, and RESTful API design — demonstrated through architecting complex, high-throughput production systems.

5+ years working in cloud environments (AWS preferred); strong understanding of how cloud services affect software design, performance, and cost — not just how to configure them.

Demonstrated experience independently driving multi-team software design decisions: writing design docs, facilitating alignment, and managing technical tradeoffs.

Strong command of distributed systems concepts: event-driven architecture, eventual consistency, multi-tenancy isolation, rate limiting, and fault tolerance — applied through code, not configuration.

Demonstrated active use of Generative AI coding tools in professional software development within the past 12 months.
