### Role Overview

Join our team as a **Java/Spring Boot Performance Engineer**, where you will focus on optimizing and enhancing the performance of our systems. Your expertise will be crucial in ensuring efficient concurrency, resource management, and network management within a distributed environment. We are looking for a professional who can drive improvements in application performance and security.

#### Responsibilities
*   Optimize Java/Spring Boot applications focusing on concurrency, blocking calls, virtual threads, schedulers, and resource management.
*   Enhance performance in AWS/EKS environments, utilizing tools such as Kubernetes, Karpenter, HPA, Argo CD, and Helm for effective networking, scaling, and observability.
*   Improve PostgreSQL/JPA performance through query optimization, indexing, N+1 elimination, connection pooling, and transaction tuning.
*   Optimize Angular/Mapbox applications for large-data rendering, GeoJSON/clustering, lazy loading, and browser performance.
*   Develop and maintain distributed systems utilizing SQS for asynchronous processing, worker patterns, retries, DLQs, and distributed locking.
*   Engage in SNMP/network-management development by handling polling, traps, OIDs/MIBs, timeouts, retries, and device communications.
*   Conduct observability and performance testing using Prometheus, Grafana, OpenTelemetry, and tools like k6, Gatling, or JMeter.
*   Implement application security measures focusing on secrets management, RBAC/authorization, tenant isolation, credential handling, secure logging, and adhering to OWASP standards.

#### Required Skills
*   Strong proficiency in Java and Spring Boot with a focus on performance engineering.
*   Experience with AWS and EKS, including Kubernetes and related tools such as Karpenter and Helm.
*   In-depth knowledge of PostgreSQL/JPA for database performance optimization.
*   Proficiency in Angular and Mapbox for front-end performance improvements.
*   Expertise in distributed systems and messaging patterns.
*   Familiarity with SNMP and network management protocols.
*   Competence in observability tools and performance testing frameworks.
*   Solid understanding of application security best practices.

#### Nice to Have

*   Experience working with US-based teams or organizations.
*   Familiarity with US regulatory standards and compliance.
