Job Description

We’re Quickline, and we believe everyone deserves great internet. Whoever you are, wherever you are and whatever you do online. So we’re on a mission to provide just that. Lightning fast, reliable broadband that reaches the places other providers leave behind. Our mission relies on a team full of inspiring people, and we’re looking for a Lead Data Engineer to build and strengthen the foundations of our data platform, delivering reliable pipelines, governed, high-quality data products that teams across Sales, Network, Customer Experience, Finance and Operations can trust. If building robust, production-grade data systems motivates you, and seeing trusted data improve how a business performs gives you a sense of achievement, we’d be very interested in learning more about your experience and expertise.

Job Responsibility

  • Build and own core data engineering foundations in a business where data is becoming central to operational performance and decision making
  • Design and deliver reliable ingestion and transformation pipelines that reduce failures and “multiple versions of the truth”
  • Create trusted, well modelled datasets that underpin executive KPIs and operational dashboards across the organisation
  • Improve platform maturity: environments, testing, monitoring, documentation, and release practices that make delivery safer and faster
  • Work closely with IT, Systems Development and business teams to align system changes with data flows and change control
  • Be part of a data function that’s building towards a modern, governed single source of truth with clear ownership and quality expectations

Requirements

  • Extensive hands-on data engineering experience within complex, high-growth or technology-led organisations, including building data platforms from inception to production
  • Proven track record of transforming fragile or fragmented pipelines into trusted, governed, production-grade data platforms through practical engineering improvements
  • Strong expertise across the full data engineering lifecycle: data ingestion, transformation and modelling, and enabling consumption through BI layers and semantic models
  • Deep hands-on experience with modern cloud data platforms, including best practices for testing, monitoring, environments, deployment, and data quality management across pipelines and upstream systems
  • Experienced leader and communicator, capable of building and developing high-performing data engineering teams while clearly explaining trade-offs and delivery decisions to non-technical stakeholders

What we offer

  • Pension – 5% employer / 5% employee contribution
  • Health Cashback Scheme – Can claim back prescription, GP and optician charges, therapy allowance, private outpatient consultations, EAP, 24/7 remote GP service, member discounts
  • 25 days annual leave + bank holidays, your birthday, house move and wedding day off
  • Option to buy or sell up to 5 additional days annual leave
  • Enhanced Paternity/Maternity/Adoption leave
  • High Street Shopping Discount Scheme - Holidays, food and drink, insurance, sport, tech, high street, Ikea, M&S, cinema etc
  • Free Parking on site
  • Regular ‘Lunch & Learns’
  • Social Events – Summer and End of Year parties etc
  • Customer Obsessed Awards - Regular opportunities to win
