Job description

Help us use technology to make a big green dent in the universe!

Kraken powers some of the most innovative global developments in energy.

We’re a technology company focused on creating a smart, sustainable energy system. From optimising renewable generation, creating a more intelligent grid and enabling utilities to provide excellent customer experiences, our operating system for energy is transforming the industry around the world in a way that benefits everyone.

It’s a really exciting time in energy. Help us make a real impact on shaping a better, more sustainable future.

Kraken Customer

What we do: build the most AI-driven, innovative, forward-thinking platform for energy management. From optimising resources to delivering cost-effective, exceptional customer experiences through advanced Customer Information Systems (CIS), billing, meter data management, CRM, and AI-driven communications, Kraken is powering the next wave of innovation in the energy industry.

Why we do it: future energy will not look like energy as we know it today. We need to not just think about our future, but build for it. Now.

About The Team

Commercials is the product group responsible for how clients bring products to market and sell them on Kraken. We build the systems that define what is sold (Product Catalogue & Contracts), how it is sold (Sales Channels), and how leads, quotes and offers move through the sales funnel. Our mission is to help clients configure and launch complex goods and services with flexibility, from self‑serve digital journeys to higher‑touch sales processes. We sit primarily within the Customer domain, partnering closely with teams across Kraken to deliver end‑to‑end sales capability.

What You’ll Need

• Commercial experience building backend systems using Python and Django (or a closely related framework such as Flask/FastAPI or similar MVC frameworks you can pivot from)
• Experience working on production systems with real users, including writing clean, maintainable, well‑tested code
• Strong understanding of core engineering fundamentals (APIs, data modelling, relational databases, debugging, performance considerations)
• Confidence collaborating in cross‑functional teams and communicating clearly about trade‑offs and technical decisions
• Comfort navigating a growing codebase and learning a complex domain over time
• A product mindset: curiosity about how what you build affects users and clients

What You’ll Do

• Build and extend core Commercials capabilities such as Product Catalogue, Leads Management, Quoting, and Sales Channel configuration
• Deliver backend features and APIs that enable clients to configure products, define sales journeys, and manage pre‑sale activity
• Work on tickets and scoped initiatives, gradually taking ownership of larger pieces of functionality
• Collaborate with product managers, engineers, and domain experts to turn evolving requirements into robust solutions
• Contribute to improving code quality, test coverage, and system reliability
• Learn the Commercials domain language (products, offers, contracts, leads, opportunities) and apply it effectively in your work

Additional context

This is a remote‑friendly role. We care more about engineering quality and long‑term potential than strict years of experience. If you’re technically strong in a comparable stack and can demonstrate sound thinking and communication, we’re open to engineers who can pivot successfully into Python/Django.
