Junior Software Engineer - Smart Pear

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.

Smart Pear is the part of Kraken Technologies that provides, amongst other things, the means by which Kraken (and so its clients) talk to smart meters. In this sense Smart Pear provides a DCC Adaptor service to Kraken and to a range of energy sector participants. We’re looking for a Software Engineer who enjoys tackling complex, ambiguous problems, is willing to dig into the detail, and has the stamina to see tough issues through to resolution. We value strong critical reasoning and learning agility at least as much as a specific technology background.

What You’ll Do

• Work day-to-day in a small, collaborative team (approx. 8 engineers) using an agile approach to deliver features, fixes and improvements to the Smart Pear platform.
• Rotate as the business-facing engineer: triage emergent issues, communicate clearly with clients and internal stakeholders, and drive incidents and requests through to resolution.
• Understand client requests and business needs to design and build the most appropriate solutions prior to controlled test and release of new features.
• Contribute to client onboarding programmes including setting up environments in AWS and ensuring that the correct configurations are implemented in third party applications, resolving emergent migration issues and overseeing the smooth onboarding of meters to our platform.
• Help understand technology and operating environment (e.g. regulatory) changes and evolve the Smart Pear product accordingly.

What You’ll Have

• Strong analytical problem-solving and critical reasoning - able to break down ambiguous problems, debug systematically and make sound trade-offs.
• Stamina and ownership: comfortable sticking with challenging investigations (including production issues) until they’re resolved.
• A STEM degree/background (or equivalent experience) that demonstrates structured, quantitative thinking; plus a grounding in computer science fundamentals (through study, a foundation course, bootcamp or practical experience).
• Experience building software in Ruby and/or Python; willing to work primarily in Ruby and grow Ruby skills quickly.
• Clear communication skills: able to explain complex technical and regulatory concepts to a wide range of audiences, including client-facing conversations.

What Will Help

• AWS (and hands‑on experience operating or deploying services in a cloud environment).
• Infrastructure‑as‑code / environment setup (e.g., Terraform) and working with JSON/XML.
• PKI / certificates / TLS and encryption concepts (even if only at a troubleshooting level).
• Java (or another JVM language), alongside Ruby.
• Domain exposure: the GB energy market, smart metering, the DCC, or other regulated/standards‑heavy environments.
