What You'll Do

You'll work across the full lifecycle of data engineering - from designing elegant solutions to deploying them in production. Your day-to-day will include:

• Building and maintaining data pipelines of varying complexity - from straightforward transformations to advanced probabilistic algorithms that drive our data science capabilities

• Designing thoughtful solutions for new challenges, with emphasis on clean architecture and maintainability

• Writing automated tests because we believe quality is built in, not bolted on

• Fixing bugs and improving existing systems - our codebase evolves constantly

• Exploring data when problems require investigation and analysis

• Contributing to backend services and internal tools that support our data infrastructure

• Deploying your work - you own it from concept to production

Our Tech Stack

• Primary: Apache Spark, Scala

• Also using: Java, Python

• Backend services: Scala, Java, Rust

• Process: Scrum and Kanban - we use what fits the work

What We're Looking For

• Strong foundation in data engineering principles and distributed systems

• Experience with Apache Spark or similar big data processing frameworks

• Proficiency in Scala and/or Java (we'll help you grow in whichever you're less familiar with)

• Solid SQL skills for data querying and analysis

• Understanding of software engineering best practices - testing, version control, code review

• Analytical mindset for data exploration and problem-solving

• Ability to balance pragmatism with technical excellence

• Fluent English - our team communicates in English daily

Nice to Have

• Experience with Python for data analysis

• Exposure to Rust

• Background in adtech or high-volume data processing

• Familiarity with probabilistic algorithms or data science concepts

What We Value

• Thoughtful design over quick hacks

• Automated testing as a core practice

• Ownership - you're responsible for what you build

• Collaboration - we solve problems together

• Continuous improvement - for our systems and ourselves
