Data Engineer
Send a job offer directly to this candidate
Data Engineer with an operations and finance background — years working with financial and operational data where errors had real consequences. It's where I learned what bad data actually costs. Now build structured pipelines on AWS and Spark, focusing on incremental processing and validation from the start.
Recently completed an intensive Data Engineering, AI & ML bootcamp focused on production-style pipelines and applied ML. Currently building independently with Airflow, dbt and Athena. Looking for a hands-on data engineering role where the work is close to the data itself — schema design, quality decisions, understanding why the data looks the way it does.
Particularly interested in data products and behavioural data modelling — the kind of work where engineering decisions directly affect what clients can trust and use.
