Job description

Overview

Octopus Energy started with a bold idea: to build Britain’s first truly digital energy supplier. By combining world-class tech with brilliant humans who care deeply about customers and driving the renewable energy transition, we became Britain’s largest energy supplier. We are scaling fast and building the next generation of products to accelerate the green energy transition, including making it effortless to switch to heat pumps, solar and EVs, launching smart tariffs, and creating renewable generation at scale. We’re also enabling our global businesses to roll out learnings, products and experiences that customers love here worldwide.

At Octopus Tech, you’ll have real ownership, variety, and the chance to shape products that make a tangible difference in people’s lives – lowering bills, enabling greener living, and delivering experiences customers genuinely love. You’ll work side by side with teams across marketing, operations, and data, and see the impact of your work in the real world, fast.

Our Global Platform Engineering team is responsible for architecting, building, and maintaining the core infrastructure, tooling, and services that enable our engineering teams to deliver at scale safely and reliably.

As a Senior Platform Engineer within this newly created team you’ll be able to take ownership of key platform areas, shaping how we build and operate infrastructure across the Octopus Energy Group. You’ll design and implement scalable solutions, mentor engineers and collaborate closely with teams to understand their needs and translate them into platform capabilities - from cloud infrastructure and CI/CD pipelines to observability and developer experience.

You’ll bring a strong bias towards automation and scale, with a deep understanding of modern cloud infrastructure best practices, balancing pragmatism with long-term thinking. Thriving in an environment that welcomes continuous improvement and new ideas, your communication skills and attention to detail will be indispensable as you turn complex challenges into simple, scalable solutions that strengthen the foundation for all engineering teams.

If this sounds exciting, we’d love to chat.

What you’ll do

• Deliver platform services and improvements through the whole software delivery lifecycle, including coding, peer reviews, testing, and deployments.
• Take ownership of key technical areas, influencing design and implementation for platform services used across the group
• Contribute to technical decisions that affect multiple teams, balancing long-term vision with pragmatic delivery
• Collaborate closely with engineering teams, communicating technical concepts clearly and constructively
• Support incident response, participate in retrospectives, and contribute to improving operational practices
• Proactively identify opportunities to automate, simplify, and scale platform services
• Provide guidance and mentorship to less experienced engineers, sharing knowledge and best practices.

What you\'ll have

• Great communication skills, working effectively with developers, product managers and other business stakeholders to understand, design and deliver impactful projects and reliability improvements
• Previous experience working in small, highly-autonomous teams
• Proficient using AWS; we use a lot of different AWS services and not just the standard few

Good expertise in multiple of the following areas:

• Docker and Kubernetes; we use Amazon EKS in production
• Datadog, or a similar logging/monitoring tool
• Messaging queues, event-driven async processing or similar technologies - we use RabbitMQ
• PostgreSQL, or a similar RDBMS
• Python development experience or equivalent
• Networking and DNS
• Terraform or a similar infrastructure-as-code tool
• Experience with a Linux distribution

Bonus points for

• Experience working in environments where shared platform services support multiple teams or products
• Interest in cross-team collaboration
• Awareness of security, compliance, or reliability considerations in regulated industries
• Some exposure to data-heavy systems (analytics, telemetry, IoT) and how to build infrastructure to support them
• Experience working with geographically distributed teams
• A proactive, innovative mindset

Why else you’ll love it here

• Salary is discussed on a call with a recruiter to match your experience with the correct salary; the team focuses on finding the right octofit.
• Octopus Energy Group offers a unique culture with autonomy and opportunities to work with co-owners on groundbreaking projects. We have been recognised as a great place to work and value leadership and employee well-being.
• Visit our UK perks hub - Octopus Employee Benefits

We would prefer someone who can work in our London office but will consider remote candidates. However, you do need to be able to work in the UK.
