Senior Software Engineer - Financials in London

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.

What we do: build the most AI-driven, innovative, forward-thinking platform for energy management. From optimizing 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.

Our team: All technology is written and maintained by a multi-discipline engineering team. This includes server-side, client-side and mobile engineers working closely with UX experts, copywriters and designers. We follow a Kanban-like approach, using Google docs and Asana to specify and manage work; Github, CircleCI and Terraform Enterprise as part of an immutable-infrastructure, continuous delivery pipeline; and Loggly, Sentry and Cloudwatch to measure performance and monitor production. Kraken is a great place to learn, work with some talented engineers and level-up your skills. Some of our coding conventions are open-source.

Our technology: On the server-side, we mainly use Python. Most of our websites are powered by Django, Django-REST-framework and GraphQL (Graphene). We use AWS heavily, employing most of the "Hashistack" (eg Packer, Consul, Terraform) as part of a continuous deployment pipeline.

What you'll do:

• Develop an innovative and highly technical product, central to Kraken's billing system used by a multitude of countries, markets, and clients.
• Abstract specific problems into generic building blocks that clients can use to build and modify their systems.
• You will be working in a multi-disciplinary software engineering team; solving design challenges; domain modeling; solving technical problems; engineering solutions for smart meters; writing robust fault-tolerant software primarily in Python, Celery, and async processing.
• We have lots of difficult design challenges to solve. The energy market is complicated, outdated, and process-heavy - there’s an awful lot of domain modeling that we need to get right. Strong attention to detail is essential.
• We have difficult technical problems to solve. With the advent of smart meters, we'll soon be processing millions of meter readings a day.
• There's a great opportunity for disruption in the energy market. The big suppliers still dominate but are not exactly popular. The energy landscape is changing as we move to more disaggregated forms of generation, with less predictability, more dynamism, and smarter technology.
• You'll be working for a company that’s fighting climate change. Our parent company is the largest investor in solar generation in the UK and is funding wind and anaerobic digestion. As a supplier, we're helping people to use greener technology and renewable energy, all helping move the world towards a lower carbon future.

What you'll have:

• Ability to think abstractly to solve general problems, not directly tied with an immediate user need.
• Skills in identifying performance bottlenecks and optimising code.
• Experience with developing development frameworks or language design.
• Experience in designing scalable and maintainable systems. Understanding of design patterns and best practices.
• Celery and async processing.
• Postgres.
• REST and GraphQL APIs.
• Plus experience in the following would be a bonus: AWS, Terraform, Packer, Consul.
