AWS Data Engineer - Inside IR35 - Investment Banking

Data Platform Engineer

City of London (Hybrid - 3 days on-site) | Contract | £700/day, Inside IR35

A well-established Japanese investment bank operating in capital markets is bringing in a hands-on Data Platform Engineer to help drive its AWS cloud transformation programme. This is a genuine build-and-run role for someone who's happiest with their hands on the keyboard, not just steering from the sidelines.

You'll be joining the Applications team to build and operate data pipelines and integration flows across front and back office systems, combining data engineering with platform engineering to deliver production-ready services. Expect a mix of hands-on AWS delivery (Glue, Lambda, Step Functions, EventBridge) and closer collaboration with the architecture team to keep implementation aligned with strategic direction.

What You'll Be Doing

• Building and maintaining data pipelines and integration flows (batch and near real-time) across the Applications landscape
• Delivering cloud-based data solutions on AWS aligned to architectural standards and the cloud transformation programme
• Implementing scalable, resilient data processing patterns, including event-driven data flows
• Working with messaging/streaming technologies to support data movement across systems
• Supporting platform reliability - monitoring, alerting, and performance optimisation
• Contributing to CI/CD, automation, and infrastructure-as-code for consistent, efficient delivery
• Mentoring and upskilling team members to embed sustainable ways of working

What We're Looking For

• Minimum 5 years' hands-on AWS engineering experience, ideally in data engineering, cloud platform engineering, or enterprise application integration
• Strong hands-on experience with AWS data platform services: Glue, Lambda, Step Functions, EventBridge, S3, Athena, RDS, Lake Formation, IAM, CloudWatch
• Strong Python development skills for Glue jobs, Lambda functions, and automation/integration workflows
• Practical experience with Terraform as primary IaC tool, plus CI/CD tooling (Bitbucket Pipelines, GitHub Actions, or GitLab CI)
• Solid data engineering fundamentals - SQL, data modelling, pipeline design, batch and near-real-time flows
• Experience with messaging/streaming/event-driven architectures (ActiveMQ/Artemis, RabbitMQ, or AWS Kinesis)
• Experience with containerised/compute platforms - Amazon EKS and EC2

Desirable

• AWS Certified Solutions Architect, Developer, or Data Engineer (or equivalent Azure/GCP with strong AWS delivery background)
• Experience with QuickSight, AWS Bedrock, or Bedrock AgentCore
• Background in financial services / capital markets or another regulated, data-heavy environment
