We’re looking for a Senior Backend Developer with a strong background in Infrastructure, DevOps, and Cloud Technologies to join our global team.
You will take ownership of our internal Domain Management System (DMS), manage our AWS-based infrastructure, and drive automation, observability, and integrations to support mission-critical services.
This role sits at the intersection of backend engineering, cloud architecture, and system reliability.
You’ll play a pivotal role in developing tools, services, and systems that ensure the resilience and performance of our digital platform, while working closely with cross-functional teams across product, operations, and engineering.

- AWS Infrastructure: Architect, deploy, and manage scalable infrastructure using Infrastructure-as-Code (CloudFormation, AWS CDK, or Terraform). Hands-on with EC2, S3, CloudFront, IAM, CloudWatch, etc.
- DevOps & Automation: Develop and maintain CI/CD pipelines, batch-processing jobs, and automated monitoring/recovery systems. Own system uptime, observability, and fault tolerance
- API & Platform Integrations: Build and maintain robust integrations with platforms such as Affise, Cloudflare, and UptimeRobot
- Internal Application: Design, develop, and maintain internal applications and platforms —such as administrative dashboards and campaign/domain management tools —that streamline operational efficiency and cross-team collaboration
English fluency is a must
4+ years of professional backend development experience, primarily in Java with Spring Boot
Strong proficiency with AWS services: EC2, S3, CloudFront, IAM, CloudWatch, and Route 53

Proven experience with REST/JSON API integration
Experience creating monitoring, uptime checks and recovery systems

Excellent communication skills and a collaborative mindset in cross-functional teams
Nice to have:

- Interest or experience in AI-driven workflows or prompt-engineering
- AWS Certifications such as Developer Associate, Solutions Architect, or DevOps Engineer
