Your opportunity:

We are looking for a Senior Data Engineer to design and operate large-scale, cloud-native data platforms supporting network experience and operational analytics.

This role focuses on building robust AWS-based data pipelines that ingest, process, and transform high-volume operational and customer data, while ensuring strict compliance with PII handling, data masking, and privacy requirements.

You will play a key role in enabling scalable, reliable data platforms that support downstream analytics, reporting, and monitoring use cases across the business.

You'll make impact by:

Cloud Data Platform Engineering (AWS)

• Design, build, and operate scalable data pipelines on AWS (S3, Glue, Lambda, Redshift, etc.)
• Develop batch and near real-time ingestion frameworks for operational and customer data
• Optimise data processing for performance, cost, and scalability
• Implement CI/CD and infrastructure-as-code practices for data platform deployments

Data Pipelines & Transformation

• Build and maintain ETL/ELT pipelines using tools such as Glue and Airflow
• Transform raw data into structured, analytics-ready datasets
• Develop reusable data models and curated data layers
• Ensure high reliability, traceability, and scalability of pipelines

Data Privacy, Security & PII Handling

• Design and implement data masking and tokenisation solutions for PII (e.g. MSISDN, IMSI)
• Build and operate masking pipelines (e.g. Glue ETL jobs processing S3 datasets)
• Ensure compliance with privacy standards and regulatory requirements
• Implement governance controls, including:
• Data classification
• Access controls and segregation
• Data lineage and auditability

Platform & Architecture Contribution

• Define and implement best practices in data architecture:
• Data lake zoning (raw, curated, masked)
• Partitioning and performance optimisation
• Contribute to AWS platform design and evolution
• Drive continuous improvements in reliability, scalability, and cost efficiency

Stakeholder Collaboration & Leadership

• Work across engineering, network, and business teams to deliver data solutions
• Translate business and operational requirements into scalable data architectures
• Provide mentorship and technical leadership to other engineers
• Own delivery end-to-end with a high degree of autonomy

What you’ll bring:

• 5–8+ years’ experience in data engineering
• Strong hands-on experience with AWS data ecosystem (S3, Glue, Redshift, Lambda, IAM)
• Proven experience building production-grade data pipelines and platforms
• Strong SQL and Python (or similar)
• Experience with orchestration tools (e.g. Airflow)
• Experience handling PII and sensitive data, including:
• Working in regulated environments
• Experience implementing data masking pipelines and controls

Ideally, you will also have:

• Experience with observability or telemetry platforms (e.g. Splunk, Grafana)
• Experience ingesting and structuring high-volume event, log, or telemetry data
• Exposure to telecom / network datasets and operational domains
• Experience working with network performance and customer experience KPIs (e.g. latency, throughput, service availability, order journey metrics)
• Experience working with home / CPE device performance data (e.g. modem/router metrics, Wi-Fi quality, device health signals)
• Familiarity with streaming platforms (Kafka, Kinesis, etc.)
• Knowledge of AWS data security tooling (e.g. Macie)

What's in it for you?

• Flexible hybrid way of working (from home and office)
• ‘Stay Connected Mobile’ – Access to a free mobile plan
• ‘Stay Connected NBN’ – Access to a free, high‑speed NBN plan (up to 500 Mbps)
• ‘Your Leave’ - an additional 4 days of leave to be used whenever you like - every year
• Access to TPG Learning Hub platform and internal development opportunities
• Access to Corporate Partner Discounts
