Senior Platform Engineer

Senior Data Platform Engineer / Data Architect Python AWS Terraform Kafka Event-Driven Architecture

We are looking for a Senior Data Platform Engineer to join a team building a modern, cloud-native data platform on AWS. This is a highly hands-on engineering role focused on designing, building, deploying, and troubleshooting platform components, not producing architecture documentation or leading governance activities.

You’ll work alongside experienced engineers to build the platform foundation that supports data products across the business. This role is ideal for someone who enjoys solving complex technical problems, writing production-quality code, and taking ownership of infrastructure and platform capabilities.

• Build, deploy, and maintain cloud-native platform components on AWS
• Develop infrastructure using Terraform (Infrastructure as Code)
• Design and implement event-driven architectures using Kafka
• Develop automation, platform tooling, and services using Python
• Deploy code through multiple environments and support platform delivery
• Build scalable, resilient, secure, and observable platform services
• Troubleshoot complex distributed systems and production issues
• Improve developer experience through automation, self-service tooling, and platform enhancements
• Collaborate closely with engineering teams to deliver reliable platform capabilities
• Contribute to platform engineering best practices and continuous improvement

We’re looking for an engineer who enjoys building systems and solving technical challenges. You’ll be comfortable getting into the detail, debugging issues, and explaining the reasoning behind your technical decisions.

• Strong hands-on experience with AWS
• Excellent knowledge of Terraform (Cloud Formation considered)
• Proven experience building Event-Driven Architectures
• Strong hands-on experience with Kafka (Confluent experience beneficial)
• Strong Python development skills
• Experience building cloud-native platforms and distributed systems
• Experience deploying and supporting applications across multiple environments
• Strong debugging and problem-solving skills

• Experience with EKS, Lambda, Fargate, DynamoDB or similar AWS services
• Experience with observability, monitoring and platform automation
• Knowledge of CI/CD pipelines and Dev Ops practices
• Experience improving developer experience and internal engineering platforms

You’ll be someone who:

• Enjoys building rather than just designing systems
• Can explain how you diagnose and resolve complex technical issues
• Has a strong engineering mindset with excellent technical depth
• Takes ownership and delivers high-quality solutions
• Thrives in collaborative engineering teams
• Brings technical maturity and pragmatic decision-making
