Senior Data Engineer | High-Growth Data Platform | Hybrid Build the foundational data mesh architecture for a premier global intelligence firm.


The Opportunity


This is a high-impact individual contributor role at the heart of a leading intelligence platform’s data engineering capability. You will join a core team of senior engineers responsible for designing and evolving the foundational infrastructure and services that power data across the entire organisation.


This is a deeply hands-on role that demands strong technical expertise and the ability to influence across teams without formal authority. You will drive the platform toward a data mesh architecture, establishing the standards that allow domain teams to operate autonomously while maintaining trust across the ecosystem.


What You’ll Be Doing

  • Design and build core platform components that form the foundation of a scalable data platform.
  • Drive the progressive realisation of a data mesh architecture and self-service tooling.
  • Evaluate and evolve the data stack, making informed recommendations on tools and services.
  • Define architectural principles and standards for data formats to ensure interoperability.
  • Implement sophisticated access controls and data masking capabilities for security and privacy.
  • Build automated quality gates and data contract validation at ingestion and serving layers.
  • Develop an observability framework and alerting mechanisms for pipeline health and incident response.
  • Design strategies for data discoverability, lineage tracking, and metadata management.


What They’re Looking For

  • Extensive experience building production-grade data platforms using dbt, Airflow, Spark, and Snowflake.
  • Practical knowledge of data mesh principles and federated data architectures.
  • Solid understanding of AWS cloud infrastructure, including networking, IAM, and compute.
  • Experience with data cataloging, lineage tools, and metadata management frameworks.
  • Ability to influence technical direction and drive alignment across teams without formal authority.
  • Strong prioritisation instincts, balancing deep technical work with organizational needs.


Nice to Have


  • Familiarity with the Apache Iceberg table format.
  • Knowledge of data contract frameworks and schema validation tooling.


Why Join?


You will join a high-performance team where engineering quality is a priority and technical leadership is practiced through mentorship and shared standards.


This role offers the chance to move beyond standard pipelines into advanced areas like data mesh and automated governance. You will have the autonomy to shape a modern architecture and the opportunity to see your work directly empower engineers across the business

How Many Machine Learning Tools Do You Need to Know to Get a Machine Learning Job?

Machine learning is one of the most exciting and rapidly growing areas of tech. But for job seekers it can also feel like a maze of tools, frameworks and platforms. One job advert wants TensorFlow and Keras. Another mentions PyTorch, scikit-learn and Spark. A third lists Mlflow, Docker, Kubernetes and more. With so many names out there, it’s easy to fall into the trap of thinking you must learn everything just to be competitive. Here’s the honest truth most machine learning hiring managers won’t say out loud: 👉 They don’t hire you because you know every tool. They hire you because you can solve real problems with the tools you know. Tools are important — no doubt — but context, judgement and outcomes matter far more. So how many machine learning tools do you actually need to know to get a job? For most job seekers, the real number is far smaller than you think — and more logically grouped. This guide breaks down exactly what employers expect, which tools are core, which are role-specific, and how to structure your learning for real career results.
