Senior Python Engineer

Job Description

Senior Python Engineer - Financial Services

You will join a financial services business reimagining their technology stack to be cloud-native on AWS, with modern front ends and Python-based services at the core.

Great engineering culture matters as well as writing clean, well-designed code, building systems that are easy to test and extend, and learning from one another along the way.

You’ll spend your time designing and building clean, reusable Python components that form the backbone of cloud-first solutions on AWS.

You’ll work on evolving existing platforms as business needs change, collaborating closely with business users to shape maintainable, well-architected software that solves real problems.

You’ll be comfortable working in a modern engineering environment, using Agile ways of working, CI/CD pipelines, and DevSecOps practices, with tools like Git and GitHub supporting your day-to-day development.

You’ll bring solid experience with Python in enterprise systems, along with hands-on knowledge of both SQL and NoSQL databases, common data structures, and data transformation patterns.

Experience with serverless and cloud technologies—such as AWS Lambda, AppSync, or DynamoDB—will help you hit the ground running.

Just as importantly, you’ll enjoy working with people.

You’ll communicate confidently with both technical and non-technical stakeholders, contribute to code reviews and pair programming, and help coach and support more junior engineers by sharing best practices and encouraging high-quality software craftsmanship.
