About the Role
We’re looking for a Senior Scala Developer with hands-on experience in building high- performance backend systems using Akka or Pekko, Play Framework, and Kafka. This is a great opportunity to work on event-driven, distributed systems that power critical business platforms.

In this role, you’ll contribute to system design, development, and optimization of cloud-native applications — collaborating with engineers, product teams, and architects in a consulting setting. We value clean architecture, observability, and long-term maintainability. You’ll be working on a highly scalable backend stack — focused on event sourcing, resiliency, and real-time processing — and expected to lead by example through best practices and technical ownership.

• Develop and maintain backend systems using Scala, Akka or Pekko (HTTP, Streams, Cluster Sharding), and Play Framework
• Design and implement event-driven microservices using Kafka
• Apply event sourcing and CQRS patterns when needed
• Build and integrate REST and streaming APIs
• Optimize application performance, throughput, and resource usage
• Ensure systems are observable and maintainable using modern logging/metrics/tracing tools
• Write unit and integration tests, and perform code reviews
• Containerize and deploy services using Docker and Kubernetes
• Contribute to architectural decisions and help improve code quality standards
• Collaborate with cross-functional teams and communicate progress effectively
• Support technical evaluations of other consultants when required, contributing to the assessment of skills and alignment with project needs

What You Bring

• 5+ years of backend development experience, with at least 3+ years using Scala
• Proven experience with Akka or Pekko, including Streams, HTTP, and Cluster Sharding
• Strong knowledge of the Play Framework
• Solid understanding of Kafka and event-driven architecture
• Experience with event sourcing, domain-driven design, and microservices
• Familiarity with observability tools (Prometheus, Grafana, OpenTelemetry, etc.)
• Hands-on experience with Docker and deploying to Kubernetes
• Comfortable working in Agile/Scrum environments
• Proficient with Git and CI/CD pipelines
• Strong communication skills – able to clearly express ideas and technical concepts in English
• Proactive mindset – takes initiative and suggests improvements
• Ownership and accountability – treats app stability and user experience as top priorities
• Collaborative attitude – works well in cross-functional, multicultural teams
• Adaptability – thrives in a fast-changing environment
• Attention to detail – mindful of UI/UX consistency and clean design
• Continuous learner – stays up to date with Flutter and mobile trends
• Familiarity with infrastructure tools like Helm, Argo CD, or TerraformCustomer-oriented thinking – focused on business value and user satisfaction

  Nice to have:

• Experience with NoSQL databases (e.g., Cassandra, DynamoDB)
• Knowledge of streaming processing tools beyond Kafka (e.g., Flink, Akka Streams)
• Background in financial systems, telecom, or large-scale transactional platforms
• Previous consulting experience or working directly with clients/stakeholders

  What We Offer

• 100% remote work to provide flexibility and work-life balance.
• Company laptop and necessary equipment to perform your role effectively.
• Competitive salary package aligned with local market benchmarks
