Kraken

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

London, United Kingdom

Full-Time

TLDR

You will design scalable systems that integrate Kraken with telecom and utility ecosystems, focusing on complex challenges like water leak detection and customer experience transformation.

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
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

Drive Architectural Improvements

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

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

Core Technical Skills

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

Nice to Have

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
