This position requires strong backend engineering expertise, deep Java experience, and the ability to work effectively in complex, evolving system environments.

6+ years of backend engineering experience with ownership of complex, production-scale systems.
Strong proficiency in Java, including experience modernizing legacy applications and working with JVM-based systems.
Solid understanding of PostgreSQL, RESTful API design, and backend performance optimization.
Hands-on experience with AWS and infrastructure-as-code tools such as Terraform, Kubernetes, and Ansible.
Proven ability to independently drive projects from design through production deployment.
Strong communication and collaboration skills across engineering, product, and platform teams.
Experience working in distributed, high-scale, or performance-sensitive environments is a plus.
Familiarity with system modernization, including monolith-to-service or containerized architecture migrations, is highly valued.
