Senior Python Developer Derby (onsite) £60,000 - £80,000
This is a senior Back End role for someone who wants to own technical direction on high-impact software that supports the UK's transition to low-carbon energy.
You'll be leading technical delivery across Python APIs and services used in real-world energy infrastructure; think power grid management, nuclear, and sustainability-focused tech.
This isn't a theory-heavy R&D role. It's about secure, scalable, performant Back End engineering that enables data to move reliably through critical systems. You'll help shape the architecture, mentor junior devs, and influence DevOps practices across a growing team.
Day to day:
* Architecting and building secure Python APIs using Django or Flask
* Deploying services to AWS, Azure, or GCP using Terraform and Kubernetes
* Mentoring devs, improving CI/CD and DevSecOps pipelines
* Managing performance, reliability, and system security
* Working with stakeholders across product, DevOps and compliance
What you'll bring:
* Deep knowledge of Python with strong experience in RESTful API design
* Cloud-native deployment skills (AWS, Azure or GCP)
* Infrastructure-as-Code with Terraform, Docker, Kubernetes
* Strong understanding of Agile and DevOps engineering culture
* Comfortable leading technical discussions and code reviews
