About the Role

As an Analytics Engineer, your mission is to ensure that every data user at CitySwift is working from a single, high-quality source of truth. You will apply software engineering best practices—like version control, testing, and continuous integration—to the world of data warehousing.

In the Data Analytics team, we sit in the information layer between our tech stack and our customers. You will play a critical role in scaling our Modern Data Information Layer. You are building scalable data models that enable our platform to deliver real-time insights to the world’s largest transport operators. If you thrive on seeing the impact of data on business decisions, if you're curious about solving business problems at scale, if you want to be at the centre of AI adoption and if you love working in a creative data-led environment, then this role is for you. 

Key Responsibilities

• Data modelling & architecture: Build & create data models that help solve business problems. Follow team conventions and best practices for data architecture design. Understand Git workflows and raise PRs for review. 
• Semantic Layer & BI development: Define, build and edit semantic layer views that power customer-facing analytics such as User Apps, Dashboards, and AI tools. Create and build scalable and reusable dashboards. 
• Engineering collaboration & deployment: Understand the essentials of how analytics are surfaced within products. Participate in cross-team meetings and follow agreed deployment processes.
• Commercial & stakeholder partnership: Understand the core commercial metrics and KPIs of the business. Respond to data requests from commercial teams. Build awareness of how data outputs are used in decision-making. 
• Team enablement & technical leadership: Seek support from senior colleagues, be curious and ask challenging questions. Share learnings with data peers. Follows established team processes and documentation standards. 

Desired Qualifications

• Experience: 3+ years in a data-centric role (Analytics, Data Engineering, or BI)
• Business Acumen: Experience with solving real-world problems with data and translating data insights into outcomes.
• Tooling Mastery: Advanced-level SQL (window functions, CTEs, optimisation). Deep familiarity with BigQuery or a similar cloud data warehouse (Snowflake, Redshift, etc.).
• Engineering Mindset: Proficient with Git and the command line. You understand why modularity, DRY (Don't Repeat Yourself) principles, and documentation are non-negotiable.
• Problem Solving: Experience handling large-scale datasets. You know how to handle time-series anomalies, null values, and complex joins without breaking the pipeline.
• Communication: Ability to explain complex data to stakeholders and justify architectural decisions based on both technical performance and business needs.
• Education: Degree in Data Analytics, Computer Science, Information Systems, Mathematics, or a related field—or equivalent experience scaling a modern data stack.

We value, recognise and reward our people

• A role with real scope, where your impact is visible, your salary is reviewed as we grow, and there are career progression opportunities as the company scales and internationalises. 
• Comprehensive health and life insurance through Laya Healthcare in Ireland and Aviva in the UK.
• Flexible working with hybrid working as the default in Ireland, core hours of 10am to 4pm, remote options depending on role and a work abroad programme of up to 6 weeks.
