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.

What You'll Be Doing

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

What We're Looking For

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.

Essential Skills

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
Nice to Have

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
About You

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
