Zusammenfassung

NewGMedia Recruitment Agency seeks a Senior Java Architect to lead the engineering of a cloud-native operator platform built around distributed services and high-volume transaction processing. You will shape architecture, drive scalable patterns, and contribute hands-on across development, data flows, deployments, and observability.

You will design microservices, implement APIs (REST/GraphQL), and ensure low latency with robust data strategies and modern tooling.

Qualifikationen

• 7+ years of professional Java development experience, including architecture design.
• Experience with low-latency, high-throughput systems, multithreading, non-blocking I/O, and microservice development.
• Strong knowledge of the Spring ecosystem, including Spring Boot, Spring Data, and Hibernate.
• Experience with REST, GraphQL, Docker, Kubernetes, Kafka, SQL, and relational databases such as PostgreSQL.
• Familiarity with NoSQL and distributed data technologies including Cassandra, DynamoDB, Elasticsearch, Redis, BigQuery, or Bigtable.
• Working knowledge of AWS, Terraform, GitLab, Grafana, Prometheus, and ELK-based observability.

Aufgaben

• Design and implement a new microservices-based system with a focus on scalability, reliability, and operating cost.
• Apply sound architecture and engineering practices to services handling high throughput and demanding latency requirements.
• Build REST and GraphQL APIs and select caching approaches that improve response times.
• Design data partitioning and data-offloading strategies for large or rapidly growing datasets.
• Configure delivery pipelines, automated checks, code-coverage reporting, and Helm-based deployments.
• Create and maintain Grafana dashboards, monitoring views, and operational alerts.

• Apply sound architecture and engineering practices to services handling high throughput and demanding latency requirements.
• Build REST and GraphQL APIs and select caching approaches that improve response times.
• Design data partitioning and data-offloading strategies for large or rapidly growing datasets.
• Configure delivery pipelines, automated checks, code-coverage reporting, and Helm-based deployments.
• Create and maintain Grafana dashboards, monitoring views, and operational alerts.

Benefits and work setup

• Flexible remote, office, or hybrid arrangements without time tracking, with generally flexible working hours.
• Paid vacation and sick leave, plus additional emergency and special-occasion leave.
• Annual health-expense budget, parental support, and performance-related bonuses.
• English classes, learning support, and assistance with conferences and seminars.
• Career development through internal promotion, a low-bureaucracy environment, and no expected overtime.
• Tools and technical resources provided, with opportunities to collaborate in a multicultural setting.
