About Us

At Basis, we're not just building a company — we're building the future.

We're redesigning the electrical systems that power our homes to fight climate change, reduce household costs, and create a better future for generations to come.

That means rethinking everything, not just what we build, but how we build it.

To do this, we need incredible people : bold, creative, sharp, thoughtful, who move fast and think differently.

That's where you come in.

The Role

We are seeking a highly autonomous Senior Infrastructure Engineer to lead the growth and optimisation of the AWS infrastructure supporting our ecosystem.

As the main owner of our platform infrastructure, you will be at the heart of our technical operations, taking charge of our existing systems with the freedom to architect and implement significant improvements.

Architect and Own AWS Infrastructure : Take full ownership of design, deployment and management of the Basis cloud ecosystem on AWS, ensuring it is secure, scalable, and cost-effective.

Manage Container Orchestration : Administer and scale Kubernetes clusters (EKS), managing lifecycle of cluster components, networking and containerized workloads.

Implement Cloud Security : Work with our security architect and engineer to implement cloud security best practices, including managing IAM roles and policies, network security (VPCs, security groups) and data encryption.

Drive the Infrastructure Roadmap : Proactively identify performance bottlenecks, technical debt and areas for improvement.

Develop a forward-looking roadmap to keep our platform scalable and resilient.

Contribute to CI / CD Pipelines : Work with backend engineers to improve continuous integration and deployment pipelines, empowering them to ship software rapidly and safely.
