Job description

EPAM is seeking a Senior Scala Engineer to join the Experimentation & Experience Controls team building a high-scale, in-house A/B testing and Feature Flagging platform for one of the world's most iconic entertainment and media companies — a global leader in streaming, entertainment brands, and digital experiences reaching hundreds of millions of users worldwide.

The platform is capable of serving millions of concurrent requests with single-digit millisecond response times, and its scope extends across the client's entire portfolio of streaming products and entertainment brands.

You will be a key part of an engaging, dynamic, and inclusive engineering organisation, grounded in Scrum and Agile practices, CI/CD, close collaboration, and a commitment to continuous learning and improvement.

Responsibilities

• Lead a significant part of the implementation, design, testing, and deployment of services running in a multi-region cloud environment
• Ensure quality and high standards for feature development through automated testing and code reviews, setting examples for others to follow
• Work with the Lead Engineer in partnership with Product and Project Management to influence roadmap and architectural decisions within the team
• Support Agile practices within the squad, actively contributing to ceremonies such as standup and planning
• Mentor less experienced engineers to help them improve their technical abilities and build their profiles within and outside the organisation
• Contribute to an inclusive culture that values learning, close collaboration, and strives for excellence

Requirements

• Strong understanding of high-quality coding, testing, and development practices
• Experience in a JVM language such as Java, Scala, or Kotlin (the team primarily uses Scala with functional programming principles and frameworks such as Cats Effect and ZIO — willingness to learn Scala is welcome)
• Familiarity designing, building, and operating distributed systems with multi-level failover and fallback strategies
• Familiarity with at least one major cloud provider: AWS, GCP, or Azure
• Familiarity with Terraform or other infrastructure-as-code (IaC) tooling
• Strong communication skills — ability to understand, frame, and simplify both technical and business requirements
• Experience mentoring and coaching engineers on technical and soft skills

Nice to have

• Experience building micro/web services — including REST and GraphQL
• Experience or interest in functional programming and its real-world applications — particularly Scala stacks such as Cats Effect and ZIO
• Experience with relational and NoSQL databases, particularly PostgreSQL, Aurora, and DynamoDB — including data modelling and query performance optimisation
• Experience with Kinesis, Kafka, or other streaming data technologies
• Familiarity with data warehouse, pipeline, and analytics platforms such as Databricks or Snowflake
• Background in high-traffic, low-latency systems serving millions of concurrent users
• Experience working in the entertainment, media, or streaming domain

We offer

• We gather like-minded people:
  • Top tech minds driving innovation in AI, cloud and digital platform modernization
  • Supportive team and agile, startup-like culture
  • Hybrid by design mode and opportunity to work remotely within Poland
  • Chance to work abroad for up to 60 days annually
  • Business-driven relocation opportunities
• We provide growth opportunities:
  • Career development programs
  • Thought leadership, mentoring, soft skills and well-being programs
  • Certification (Anthropic, Gemini, GCP, Azure, AWS)
  • English classes
• We cover it all:
  • Stable pay
  • Participation in the Employee Stock Purchase Plan with a 15% discount
  • Benefits package (health insurance, multisport, shopping vouchers)
