Lead Software Engineer – Kraken Utilities; OSS​/Telco Integrations

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, Talk Talk, and Cuckoo
, and a global team of 120+ people
.

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.

• Design and develop new components of the Kraken platform for broadband utilities

• You will 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

  • API & Platform Development

    • Develop robust APIs connecting Kraken to external telco infrastructure

    • Improve integration reliability and scalability

  • Automation

    • Create workflows to streamline operations between Kraken and partner systems

• Reduce tight coupling between integrations and core business logic (e.g. Order Management, Quoting, Charging)

• Improve system stability and developer productivity

• Lead on microservice design
  , contract testing
  , and integration patterns

• Build facades and emulators to simulate integrations

• Treat internal developers as first-class customers

• Design and build an SDK layer for third party developers

• 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

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.

• 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

• 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
