At Umbrella, we’re building cutting-edge cloud cost optimization solutions that help global organizations manage and reduce their cloud spending efficiently.
We’re looking for a strong Senior Backend Developer (Java) to join our core R&D team and take full ownership of complex, large-scale backend projects.

This role is hands-on and perfect for someone who thrives in a fast-paced environment, loves solving hard problems, and has real-world experience working with large volumes of data.

• Design, develop, and maintain highly scalable backend services in Java.

• Build robust and efficient systems capable of handling large-scale data processing and migrations.

• Solve complex concurrency and multi-threading challenges in production systems.

• Occasionally contribute code in Python (for specific tools or integrations).

• Collaborate closely with DevOps, Product, and Data teams across the company.

• Take ownership of end-to-end projects, from concept through architecture, development, and deployment.

• Drive technical excellence, best practices, and innovation within the backend systems.

• 5+ years of hands-on backend development experience, primarily in Java.

• Strong understanding and practical experience with Big Data environments and large-scale data processing.

• Solid experience with multi-threaded programming, distributed systems, and performance optimization.

• Comfortable or open to occasional coding in Python (even if Python is not your primary language).

• Familiarity with microservices architecture, Docker, Kubernetes, and CI/CD workflows.

• Experience working in cloud environments (AWS, GCP, or Azure – advantage).

• Strong problem-solving abilities, analytical thinking, and proactive ownership.

• Excellent interpersonal skills and ability to work effectively in a collaborative environment.

• Practical experience working with language models (LLMs) or AI/ML tools (e.g., integrating LLMs like GPT into production systems).

• Experience with Kafka, Redis, or ElasticSearch.

• Familiarity with cloud cost optimization or FinOps domains.
