About the Role:

We’re looking for an experienced Java Backend Developer to join our engineering team working on a distributed system that processes and manages real-time alerts, presence detection, and camera-based events. You’ll contribute to the development of high-availability services deployed across microservices and AWS infrastructure.

Requirements:

• 8+ years of experience in Java backend development.
• Deep understanding of clean code, modular architecture, and distributed systems.
• Experience with database modeling and time-series data (e.g., TimescaleDB/Postgres).
• Solid grasp of AWS services (especially SQS, S3, SNS) and IAM credentials management.
• Familiarity with JWT-based auth flows and secure token verification.
• Familiarity with AWS Elastic Beanstalk.
• Comfortable working in a highly modular Gradle project with internal and external dependencies, including Bazel.
• Good communicator and collaborator – able to work across teams and modules.

Job Responsibilities:

• Design, build, and maintain backend services using Java 8+.
• Work across a modular codebase spanning multiple Gradle subprojects (alerts, analytics, media, auth, etc.).
• Implement and maintain API endpoints, token verification flows, and SQS message handling pipelines.
• Write unit and integration tests using JUnit and Mockito; manage coverage with JaCoCo.
• Optimize performance with TimescaleDB/PostgreSQL and participate in schema design.
• Work with AWS SDK for Java (v2.25+) to integrate with S3, SQS, SNS, and IAM.
• Collaborate on DevOps practices: Docker-based environments, GitHub Actions, and internal Maven publishing.

Good to Have:

• Programming language experience in OOP and strongly typed languages.
• Working knowledge of agile approaches.
• Experience with NoSQL databases.
• AWS Cloud certification is preferred.
• Experience with observability tools and performance tuning.
• Exposure to computer vision pipelines or event-based alerting systems.
• Familiarity with legacy media management, inference systems, or IoT camera networks.

What We Offer:

• A hybrid, flexible working policy.
• Professional growth and development opportunities.
• An international team of world-class engineers that brings positive energy.
• A friendly, supportive, and relaxing working environment in our offices.
