This is a hands-on role ideal for someone who thrives in a fast-paced, high-growth environment and is passionate about building scalable data infrastructure.  It is a great opportunity to join at a time when the data function is nascent so you will be making a significant mark on the business going forwards.

The Role:

As a Data Engineer, you will be responsible for developing and maintaining data pipelines that ingest, transform, and deliver data from various sources to support business intelligence, analytics, and operational reporting. You will collaborate primarily with the Head of Data & Intelligence but also with cross-functional teams to understand data requirements, implement efficient data workflows, and ensure data quality and governance. Your work will directly support CSL’s strategic and operational goals, helping to embed a data-driven culture across the organisation.

CSL is a market leader in IoT critical connectivity which necessitates our products to be secure, reliable and mission-critical therefore we process high volumes of close to real time data (e.g. network availability, device polling) alongside traditional operational data (e.g. sales, activations) that is less time sensitive.

Key Responsibilities:

Data Pipeline Development & Maintenance

• Contribute to design, build, and maintain scalable data pipelines for batch and real-time data processing.
• Integrate data from various sources including signalling/IoT devices, databases, APIs, and third-party platforms.
• Implement ETL/ELT/data pipeline processes to transform raw data into reporting-ready datasets.
• Produce up to date documentation describing all tooling and processes put in place and get this signed off by the Head of Data & Intelligence and Data Architect
• Work closely with engineering to enable ingestion of critical product telemetry data to allow (close to) real-time product performance observability.

Platform & Architecture Support

• Work closely with the Head of Data & Intelligence on the implementation of CSL’s modern data platform as required including potentially data warehouse, lakehouse and cloud-native architecture.
• Implement the recommended tools and technologies for data ingestion, storage, and processing.

Data Quality & Governance

• Implement data validation, cleansing, and reconciliation processes to ensure data accuracy.
• Collaborate with the Head of Data & Intelligence to align with CSL’s data governance standards.
• Monitor pipeline performance and proactively address data issues.

Collaboration & Stakeholder Engagement

• Work closely with the Senior Data Analyst to understand reporting requirements and deliver data solutions.
• Partner with product, engineering, and business teams to support data needs.
• Provide technical guidance and support to stakeholders on data-related initiatives.
• Enable other technical members of the team to self-serve data through pre-approved patterns, pipelines and tools

Innovation & Continuous Improvement

• Stay abreast of emerging trends in data engineering, cloud platforms, ML/AI and big data technologies.
• Identify opportunities to improve data pipelines, workflows and reduce operational overhead.
• Contribute to the roadmap for advanced analytics, ML/AI, and real-time data use cases.

What Success in the Role Looks Like

• Reliable and scalable data pipelines are in place to support analytics and reporting.
• Data within your purview is accurate, timely, and accessible across the organisation.
• Stakeholders are empowered with high-quality data to make informed decisions.

A collaborative and data-driven culture is fostered across business units

Ideal Experience and Knowledge:

• Proven experience in data engineering or related roles within a fast-paced environment.
• Strong proficiency in programme & scripting such as SQL, Python, PySpark and data pipeline frameworks (e.g., Airflow, dbt).
• Experience with some of the major cloud data warehouse and platforms (e.g., Snowflake, Redshift, ADF, Databricks, MS Fabric etc).
• Good engineering & DevOps process and tooling experience, e.g. Github
• Solid understanding of data modelling, ETL/ELT, data pipelines, and data warehousing.
• Experience working with high-frequency, high-volume data from connected devices or sensors is a strong advantage.
• Excellent problem-solving skills and attention to detail.
• Expertise in BI tools (e.g. Power BI, Tableau, Looker) preferred but not essential
• Strong communication skills, with the ability to collaborate effectively with technical and non-technical stakeholders.
