Lead Software Engineer – Kraken Utilities (OSS / Telco Integrations) in London

About Kraken Utilities

Kraken is a globally proven technology platform, already licensed to support over 55 million customer accounts, with a target of 100 million by 2027. It is one of the most advanced, AI-driven platforms for utility management—covering billing, CRM, meter data, and intelligent customer communications. We are now extending Kraken beyond energy into water and broadband, forming a new division: Kraken Utilities. Over the past three years, this team has been built from the ground up to re-architect and evolve Kraken for new industries—solving complex challenges like water leak detection, customer experience transformation and high-volume data processing. We are in a rapid growth phase, with clients including: Severn Trent, Leep, Portsmouth Water, Essential Energy, TalkTalk, and Cuckoo, and a global team of 120+ people.

The Opportunity

This is not a “business-as-usual” engineering role. You will play a key role in shaping how Kraken integrates with telecom and utility ecosystems—designing systems that are scalable, resilient, and developer-friendly. You’ll act as a systems thinker and architect, solving multi-team challenges and building platforms that other engineers (internal and external) rely on.

What You’ll Do

• Design and develop new components of the Kraken platform for broadband utilities.
• Work closely with (and help shape) the OSS & Integrations function, which is responsible for:

• Partner Integrations
• Build and maintain integrations with telecom network providers, CPE (router) providers, and call record systems.
• Handle a mix of REST and SOAP APIs to provision and query network state.

Team & Culture Impact

• Help scale Kraken Utilities by embedding a strong engineering and customer-first culture.
• Influence how teams are structured and how systems evolve.
• Take ownership of architectural direction and execution.

What We’re Looking For

We’re looking for an empathetic leader who enjoys solving complex system problems. You’ll be responsible for leading a team of engineers, making decisions on how the team operates and setting the technical direction of the team. You’ll be curious about AI developer workflows, ready to experiment and introduce new ways of working. This role will involve line management duties, as well as being hands on and close to the code. You’ll be responsible for ensuring the quality of the code being delivered through thoughtful code review. Work with other engineering teams and external engineering teams regularly. Work with client delivery to help prioritize, deliver and maintain work required by clients. Be responsible for monitoring and alerting of production systems and where required, lead and manage incidents.

Technical Skills

• Experience with Python stack and Web frameworks.
• Strong domain modelling skills.
• HTTP & REST APIs.
• Building robust, fault-tolerant systems.

• Experience building SDKs or APIs for other developers.
• Experience with microservice design.

What Makes This Role Different

• You’ll work on platform-level architecture, not just features.
• You’ll design systems that impact multiple teams and external partners.
• You’ll help redefine how developers interact with Kraken via SDKs and abstractions.
• You’ll have real ownership in shaping both technology and team structure.
