Senior Scala/Data Engineer

We are looking for a Senior Scala / Data Engineer on behalf of our client — a company operating in a highly data-intensive, distributed systems environment. This is a hands-on role for an engineer who doesn't just build services, but owns large-scale data processing systems end-to-end.

If you enjoy working on complex data flows, optimizing performance at scale, and designing resilient distributed architectures — this role is for you.

You will play a key role in shaping how data powers products, working on systems where efficiency, scalability, and fault tolerance are critical.

What you'll do

• Design, build, and optimize distributed data processing systems using Scala
• Develop high-throughput, low-latency data pipelines
• Work with big data frameworks such as Spark and distributed architectures
• Build and maintain scalable backend services for data-intensive workloads
• Optimize the performance of data jobs and the underlying infrastructure
• Ensure fault tolerance, resilience, and reliability of distributed systems
• Implement monitoring, logging, and observability for pipelines
• Collaborate with engineering teams on scalable system design
• Contribute across backend and data engineering domains
• Maintain high standards of code quality, performance, and maintainability

What we're looking for

• Strong production experience with Scala
• Proven background as a Senior Data Engineer or Backend Engineer in data-heavy environments
• Solid understanding of distributed systems and parallel processing
• Hands-on experience with Spark, Kafka, or similar technologies
• Strong knowledge of the JVM ecosystem and performance tuning
• Experience building high-load, scalable systems
• Strong system design and architectural thinking
• Ability to work independently and take ownership
• Strong problem-solving skills in complex systems
• English level: B2+ (C1 preferred)
• Availability to work in EU time zone

Nice to have

• Experience with functional programming paradigms
• Cloud experience (AWS / GCP)
• Experience with stream processing (Flink, Akka Streams)
• Background in low-latency / real-time systems
• Experience in niche or technically complex domains

What's in it for you

• Opportunity to work with a top-rated employer (DOU 2025)
• Challenging projects that drive real technical growth
• Collaborative, proactive, and supportive team
• Comfortable and modern office in Kyiv (with power backup)
• Minimal bureaucracy and a regular feedback culture
• Team events, both online and offline
