Build data products that shape global telecom decisions
At Opensignal, we don’t just process data, we turn billions of real-world data points into the insights that drive how telecom operators compete, invest, and grow.
We’re looking for a Data Engineer who wants to do meaningful work at scale. If you enjoy building robust pipelines, solving complex data problems, and seeing your work directly influence real-world strategy, this role is for you.

What you’ll do

Own and scale data pipelines processing massive datasets using Spark and Scala on AWS

using agentic AI tools.

Transform raw data into high-impact insights used by global customers and analysts
Design and build resilient data systems with a focus on performance, quality, and reliability
Partner with Data Scientists, Product, and Analytics teams to turn ideas into production-ready data products
Debug, optimise, and continuously improve pipelines through deep root cause analysis
Champion engineering best practices, testing, CI/CD, and clean, maintainable code

Why this role stands out

Real impact: Your work directly influences customer acquisition and retention strategies for major telecom players
True ownership: You won’t just contribute; you’ll own pipelines and shape how data flows across products
Scale & complexity: Work with large, messy, real-world datasets—not toy problems
Collaborative environment: Work closely with highly skilled Data Scientists and Engineers globally
Growth opportunity: Stretch into more senior responsibilities as you deepen your expertise

What you bring

2–5+ years building data pipelines with Apache Spark
Strong coding skills in Scala (or Java with willingness to learn Scala)
Confidence writing complex, performant SQL
Hands-on experience with AWS (S3, EC2, EMR or similar)
A solid understanding of data pipelines, ETL/ELT, and distributed systems
A natural curiosity, you enjoy digging into data issues and figuring out the “why”
Strong collaboration skills, you’re comfortable working across teams

Nice to have (but not essential)

Experience in full agentic AI coding using Codex or Claude.
Experience with Airflow or similar orchestration tools
Exposure to Python for data workflows
Familiarity with Redshift, Athena, or other analytical databases
Experience with ML/data science workflows in production
