Data Engineer

Data Engineer

We’re looking for a Data Engineer to join our fast-moving, hands-on data engineering team. This isn’t a traditional pipelines-for-analysts role - you’ll be building data systems and products that directly power real-time applications, internal tooling, and commercial projects across the business.

Entrepreneurial and autonomous - we prototype fast, ship often, and embrace hands-on problem-solving; maturing projects as they become foundational parts of the company's infrastructure, whether that means writing resilient, test-driven code, designing for observability, or building systems that can scale and recover gracefully. You’ll have the space to experiment and the responsibility to stabilise when it counts.

You’ll work across AWS and GCP, using a modern, containerized, event-driven stack. From real-time data processing to batch workflows, from APIs to backend services, you’ll help evolve our data fabric — the foundation for how data flows and generates value across the business.

What you’ll be doing:

-Design and build real-time, event-driven, and batch data pipelines using Python.

-Develop and deploy containerized microservices using Docker, running in ECS Fargate or similar cloud-native environments.

-Work across AWS and GCP, leveraging services like Lambda, Kinesis, SQS, EventBridge, AWS Batch, Spark, and BigQuery to power cross-cloud data products.

-Build and integrate with RESTful APIs to expose data services and connect systems.

-Contribute to CI/CD pipelines using Terraform, Docker, and Git-based workflows.

-Write unit and integration tests using pytest, applying TDD principles where it makes sense.

-Use ORMs and validation frameworks (e.g. Django ORM, Pydantic, SQLAlchemy) to model and persist data cleanly.

-Help monitor and debug production systems using tools like CloudWatch, X-Ray, and structured logging.

-Collaborate on prototype-to-production projects - balancing speed and stability depending on context.

What we’re looking for:

-Experience: 3+ years in data engineering or backend development, ideally in a fast-paced or product-led environment.

-Python skills: Confident writing clean, modular, and testable code - you’ve likely worked with pytest and TDD where it makes sense.

-Cloud Fluency: Solid experience with AWS (especially Lambda, Kinesis, SQS, EventBridge) and familiarity with GCP, including BigQuery.

-Containerisation: Comfortable building and deploying containerised applications using Docker, ideally in ECS Fargate or similar.

-APIs & Microservices: Hands-on experience building and integrating with RESTful APIs using FastAPI, Django REST Framework, or similar.

-Data Workflows: Experience designing and maintaining real-time and batch data pipelines, including dbt Core and stream processing tools.

-Infrastructure Know-How: Confident working with Terraform and CI/CD pipelines in a cloud-native environment.

-Database Familiarity: Skilled in both SQL and NoSQL (PostgreSQL, DynamoDB, OpenSearch, or equivalents), using ORMs like Django or SQLAlchemy.

-Observability & Monitoring: Comfortable using tools like CloudWatch, X-Ray, and structured logging to keep systems running smoothly.

-Mindset: Curious, Collaborative, and Proactive - you enjoy solving problems hands-on and aren’t afraid to experiment, learn, and iterate.
