JOB SUMMARY
Client is looking for a strong Scala backend engineer with microservices experience to work in a small, agile team. The team develops client-facing REST APIs that provide data for IP TV (television over the internet), for functionality such as consumer entitlement verification, on/off-net verification, parental control verification, and settings.
The technology stack includes Scala, Scalatra, Memcached, Kafka, MongoDB, docker, Kubernetes, Splunk and Datadob. All code is written in a functional style, and is fully asynchronous using Scala Futures. The team works at scale, handling hundreds of millions of REST calls per day.
Engineers on this team create new microservices and improve existing microservices. Projects are usually of considerable complexity and require a mastery of development tools. Engineers are expected to design and implement scalable, dependable systems as needed. As this is a small team, engineers must be self-starters, capable of handling responsibility and making decisions.
Required Qualifications /Detail Job Description and expectations:
- Design and develop RESTful APIs using Java and Scala using scalantra or any functional programming experience.
- Build event-driven services and microservices that produce and consume messages via Apache Kafka.
- Implement backend systems using frameworks like Spring Boot, Akka HTTP, or Play.
- Ensure reliable, fault-tolerant Kafka integration, including schema validation, error handling, and retries.
- Collaborate with frontend and platform teams to define clear API contracts and integration patterns
- Contribute to code quality, testing, and CI/CD automation
- Monitor, troubleshoot, and optimize performance of services and API endpoints
- Strong programming experience with Scala (Akka, Play, or Cats/Scalaz) and Java (8 )
- Hands-on experience with Apache Kafka (producer/consumer APIs, Avro/Protobuf, topic design)
- Experience building and consuming RESTful APIs and optionally GraphQL APIs
- Knowledge of functional programming and reactive patterns
- Familiarity with Spring Boot, asynchronous programming, and dependency injection
- Strong unit and integration testing practices
- Comfortable with Git, CI/CD pipelines, and API security (OAuth2, JWT)
Nice to Have
- Kafka Streams or Akka Streams experience
- Exposure to Kafka Connect, Schema Registry, and message validation patterns
- Knowledge of Docker, Kubernetes, and cloud-native app development
- Familiarity with API gateways (e.g., Kong, Apigee) or service mesh (e.g., Istio)
