Data Engineer

We are looking for a talented Data Engineer to help us build and maintain robust, scalable, and efficient data infrastructure - from ingesting data from third-party sources, to the pipelines and orchestration that move our data, to the models that shape it. Working closely with analytic engineers, analysts, and business stakeholders, you'll help transform raw data into valuable insights that drive business decisions. We're hiring across a range of experience levels - from engineers developing pipelines and models independently, through to those leading the design of larger, higher-scope systems.

• Strong proficiency in SQL, with experience in relational and/or NoSQL databases. • Experience designing and maintaining data models (dimensional, normalised, or wide-table approaches) and schema design for analytics or product use cases. • Hands-on experience building and maintaining ETL/ELT pipelines and ingesting data from third-party or internal sources, using modern data engineering tools (e.g., Apache Airflow, Dataflow, or similar). • Experience with cloud data platforms, particularly Google Cloud Platform (BigQuery, CloudSQL, Dataflow, Pub/Sub) or equivalent AWS/Azure services. • Proficiency in Python or another programming language commonly used in data engineering. • Experience with version control (Git) and CI/CD practices. • Knowledge of data governance, security best practices, and data privacy regulations. • Strong communication skills, with the ability to explain technical concepts to non-technical stakeholders. • Bachelor's degree in Computer Science, Engineering, or related field, or equivalent practical experience.

We're hiring across a range of experience levels - from engineers developing pipelines and models independently, through to those leading the design of larger, higher-scope systems. The main elements of this role will involve: • Data modelling and pipeline development: Design, develop, and iterate data models and schemas, and build ETL/ELT pipelines to process large volumes of data efficiently and reliably. • Data infrastructure development: Implement and maintain scalable data architectures and pipeline orchestration (scheduling, dependencies, retries) using cloud technologies, ensuring high availability and performance. • Data quality and governance: Implement data quality checks, monitoring, and validation processes to ensure data accuracy and consistency across systems. • Collaboration and delivery: Work closely with engineers, data scientists, AI/ML engineers, analysts, and business teams across the company to understand requirements and deliver data solutions that meet their needs. • Technical innovation: Stay current with emerging data technologies and best practices, proposing and implementing improvements to our data infrastructure and processes. • Documentation and knowledge sharing: Create and maintain technical documentation, share knowledge with team members, and contribute to engineering best practices. • Be a reflection of the GC Values that help us work with one another effectively. Who we're looking for You'll enjoy this role if: • You're passionate about working with data at scale and solving complex data challenges - whether that's shaping how data is modelled, how it moves, or how reliably it's delivered. • You write clean, maintainable, and efficient code, and care about getting the details right. • You enjoy collaborating across diverse teams, and can translate business requirements into technical solutions. • You think critically and solve problems methodically - debugging complex data issues and optimising system performance. • You take ownership of your work, proactively looking for ways to improve it. • You're eager to learn and grow in a fast-paced fintech environment.
