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


BenefitsWe believe we are stronger when we not only celebrate our many differences, values, and voices but also include them in everyday practice. Having a diverse and inclusive culture is essential, which is why we offer a flexible approach to work-life balance, operating in a remote-hybrid way. We'll help you get set up with the essentials you need to work from home or the office. We also offer an attractive range of additional benefits, including:

  • Competitive compensation packages; including a long-term equity program.
  • Comprehensive group benefits package.
  • Company sponsored retirement savings plan.
  • Professional development opportunities: education reimbursement, learning allowance, company-sponsored workshops, and more!
  • Generous holiday allowance, sick leave, parental leave, flexibility including Summer Fridays, and the opportunity to work from abroad.
  • Charity matching and time off for community volunteering.
  • Regular virtual and in-person events and socials.
