Role Overview

We are looking for a highly experienced Senior Scala/Pekko Engineer to design, develop, and maintain scalable, resilient, cloud-native backend applications. The ideal candidate will have strong expertise in Scala, Pekko or Akka, distributed systems, event-driven architecture, and modern backend engineering practices.

You will contribute to architecture and technical design decisions, build reliable microservices and APIs, and help deliver high-performance systems using AWS, Kafka, Docker, and Kubernetes. The role requires strong engineering ownership, architectural thinking, and the ability to collaborate with product, frontend, and SRE teams.

Key Responsibilities

- Design, develop, and maintain scalable, highly available backend services using Scala and modern functional programming practices.
- Build asynchronous, concurrent, and fault-tolerant applications using Apache Pekko or Akka.
- Develop clean, maintainable, testable code using Scala libraries and functional programming tools such as Cats and Cats Effect.
- Contribute to system architecture, distributed systems design, microservices, API contracts, and technical decision-making.
- Design and implement Event Sourcing, CQRS, Domain-Driven Design (DDD), and event-driven architectures using Kafka.
- Build resilient, high-performance APIs and distributed services with appropriate error handling, recovery, and concurrency controls.
- Develop, deploy, and operate cloud-native applications on AWS using Docker and Kubernetes.
- Work with relational and non-relational databases, ensuring data consistency, performance, and appropriate data modelling.
- Establish and maintain automated testing, code quality standards, observability, logging, metrics, and production reliability.
- Contribute to CI/CD pipelines, deployment automation, and continuous improvement of software delivery practices.
- Collaborate with Product, Front-End,



and SRE teams to translate business requirements into reliable technical solutions.
- Participate in code reviews, architecture discussions, technical mentoring, and knowledge-sharing activities.
- Take end-to-end ownership of engineering outcomes, troubleshoot complex production issues, and challenge technical decisions constructively.

Required Technical Experience
- 12+ years of software engineering experience, with strong hands-on expertise in Scala backend development.
- Robust practical experience with Apache Pekko and/or Akka for concurrent, asynchronous, and distributed applications.
- Solid understanding of functional programming, including practical use of Cats and Cats Effect.
- Strong knowledge of distributed systems, microservices, concurrency, fault tolerance, and API design.
- Hands-on experience with Kafka and event-driven architectures.
- Practical knowledge of Event Sourcing, CQRS, and Domain-Driven Design.
- Experience building and operating cloud-native backend services on AWS.
- Hands-on exposure to Docker, Kubernetes, CI/CD, automated testing, and production monitoring.
- Experience with relational and non-relational databases.
- Strong problem-solving, communication, technical ownership, and cross-functional collaboration skills.

Preferred / Additional Experience
- Experience migrating or modernizing Akka-based systems to Apache Pekko, or working with both ecosystems.
- Experience with production-scale distributed systems and high-throughput event processing.
- Experience with Java or Python as complementary backend languages.
- Familiarity with production observability, performance tuning, resilience testing, and incident management.

What Success Looks Like
- Delivering reliable, maintainable, and scalable backend services.
- Making sound architecture decisions for distributed and event-driven applications.
- Improving service resilience, observability, performance, and deployment quality.
- Taking ownership of complex engineering problems from design through production support.
- Working effectively with cross-functional teams in an Agile product environment.
