The opportunity

We're looking for an exceptional Senior Python Engineer to join a major, multi-year technology programme at National Grid, helping to build a new customer CRM platform from the ground up.

The platform is currently in the discovery phase, making this a genuine greenfield opportunity to influence architecture, engineering standards and ways of working from the outset.

The platform will support a range of customer interactions, including login issues, enquiries, complaints and wider customer service activity.

You'll work across multiple front-end and back-end engineering teams in an Agile environment. This is a hands-on engineering role - we're looking for someone who is an excellent Python engineer but can also influence, guide and share best practice across teams.

What you'll be doing

Designing and building high-quality, production-grade Python services and applications.

Contributing to the architecture and technical foundations of the new platform.

Working with Product Owners to shape scope, backlogs and technical roadmaps.

Supporting discovery, technical design and delivery planning.

Working across multiple codebases and development teams.

Sharing engineering best practice and helping establish consistent standards.

Mentoring engineers, conducting code reviews and raising engineering capability.

Building scalable, resilient and maintainable services.

Working with event-driven architecture and Apache Kafka.

Developing cloud-native solutions using AWS, including Lambda and API Gateway.

Working with DynamoDB / NoSQL, with SQL and relational database experience desirable.

Contributing to Agile planning, refinement and continuous improvement.

What we're looking for

Above all, you'll be a genuinely strong, hands-on Python engineer with the technical depth to build and the influence to help others build well.

You'll have:

Extensive commercial Python experience.

Strong AWS experience, including services such as Lambda and API Gateway.

Practical experience with Kafka and event-driven architecture.

Experience with DynamoDB or other NoSQL technologies.

Ideally, experience with SQL and relational databases.

Strong software...
