About The Position

This is a backend engineering role for someone who genuinely enjoys working in complex legacy systems, not just maintaining them, but charting a clear path to something better. You'll contribute to the modernization of AMS's backend, partnering with the team to make technical decisions that improve performance, scalability, and maintainability over time.

Requirements

• 6+ years of backend engineering experience with a track record of owning and delivering complex systems
• Strong proficiency in Java, including experience working with and modernizing legacy systems
• Solid understanding of PostgreSQL, RESTful API design, and performance optimization at scale
• Hands-on experience with AWS and infrastructure-as-code tools (e.g., Terraform, Kubernetes, Ansible)
• Demonstrated ability to drive projects independently, from design through production
• Strong communication skills and the ability to collaborate effectively across engineering, product, and platform teams

Nice To Haves

• Experience with additional languages such as Python, TypeScript, or C#
• Proven experience migrating monolithic systems to containerized or service-oriented architectures
• Background in data-intensive, high-scale, or security-sensitive environments
• Strong grasp of JVM and troubleshooting memory/CPU issues
• Familiarity with frontend technologies (e.g., React)
• A Bachelor’s degree in Computer Science or a related field

Responsibilities

• Own and deliver backend features end-to-end, contributing to the modernization of AMS’s backend architecture (e.g., upgrading from Java 11 to a current LTS version and evolving toward containerized, multi-tenant, cloud-native systems)
• Design and optimize API workflows and data models, improving system performance, scalability, and PostgreSQL query efficiency
• Lead efforts to introduce asynchronous processing patterns, eliminate deprecated code, and modernize build and dependency management systems
• Partner with Platform Engineering to enhance CI/CD pipelines, infrastructure, and deployment workflows using tools like Terraform, Kubernetes, and Ansible
• Contribute to architectural decisions and technical direction within the AMS domain, balancing short-term delivery with long-term scalability
• Mentor and support junior engineers, raising the overall technical quality and engineering standards of the team
• Participate in on-call rotations, proactively improving system reliability, observability, and incident response practices
