Full job description

Overview

This is a Staff Data Engineer opportunity focused on building the data layer behind how modern software is stored, secured, and delivered at serious scale.

The platform handles tens of millions of requests daily and petabytes of data monthly, with data feeding directly into the product rather than sitting behind it.

Current areas of focus include:

  • Building CDC pipelines so every change is tracked and nothing is lost
  • Handling billions of events in near real-time
  • Redesigning log and export systems at scale
  • Laying the foundations for AI-driven insights
    This role combines greenfield platform work with scaling existing systems.

What You'll Be Doing

  • Shape the data platform architecture
  • Build high-throughput, reliable pipelines
  • Work across teams including security, product, and billing
  • Solve system-level problems, not just tickets
  • Raise the bar for how data is used across the platform

What You'll Need to Succeed

  • Strong data engineering experience at scale

  • Experience with distributed and event-driven systems

  • AWS and modern tooling such as Kafka, Kinesis, and Postgres

  • Strong coding skills in Python and SQL
    Just as importantly, you'll bring:

  • A strong interest in how data is actually used

  • A systems mindset, not just a pipeline mindset

  • Comfort working without a playbook or perfect specs

What's In It for You

  • Core product infrastructure work, not reporting
  • Real scale and real complexity
  • Plenty of greenfield opportunity
  • A data platform that is central to what gets built next
  • Small team, high ownership, engineering-led environment
  • Competitive salary plus stock in a recently funded, high-growth environment

Additional Information

Candidates must be based in Ireland or the UK and have the right to work. No sponsorship is available.

Location: Dublin - City Centre

Salary: EUR 130000 - 140000 / Year
