A bit about us

At Gamma we provide voice, data, and mobile solutions to businesses across the UK, Germany, Spain, and the Benelux region.

Our people are at the heart of everything we do. When you join us, you’ll be part of a collaborative, forward-thinking team that’s transforming how businesses connect and communicate globally.

We’re growing fast, but we never lose sight of what matters: our people. Whether you're looking to develop your skills, take on new challenges, or make a meaningful impact, Gamma is the place to do it.

What is the role responsible for?

As a Lead Software Engineer, you will play a key role in developing and maintaining Gamma’s Group Products suite, including proprietary OSS/BSS and UCaaS & CCaaS solutions.

Leading technically complex development across the platform, building new features and maintaining existing systems using TypeScript, Node.js, and React
Collaborating with product, architects, and engineering teams to scope, plan, and estimate solutions that are scalable and future-proof
Designing and developing secure, high-performance APIs and integrating third-party tools and services
Producing and reviewing detailed Solution Design documentation, ensuring consideration of security, performance, and system-wide impact
Driving high standards through code reviews, mentoring engineers, and contributing to CI/CD and testing best practices
ing site reliability engineering principles to improve observability, resilience, and incident response
Monitoring, profiling, and optimising application performance, including capacity planning to meet SLAs
Identifying technical debt and recommending improvements to systems, processes, and tooling

What you’ll bring

You don’t need experience in everything listed, but we’re especially keen to hear from people with some of the following skills:

Strong experience with TypeScript, Node.js, and modern frontend frameworks such as React or Angular
Deep understanding of software architecture, design patterns, and API design principles
Experience working with CI/CD pipelines, automated testing frameworks (e.g. Jest, Playwright), and version control
Proven experience running large-scale production systems in AWS and working with Kubernetes/containerisation
Strong debugging, performance optimisation, and problem-solving skills across distributed systems
Experience mentoring engineers and contributing to technical leadership within teams
Knowledge of observability, monitoring, and site reliability engineering practices
Experience with Java and/or telecoms technologies (e.g. VoIP, WebRTC) is highly beneficial

What do we offer you?

25 days annual leave + birthday
Subsidised private medical insurance
5.1% matched pension contributions
Enhanced parental leave
Life assurance and Income protection
save and incentive plans
Electric Vehicle and Cycle scheme
Employee discounts
Volunteer day

A few things to note

We require all candidates to be eligible to work in the UK and pass a basic DBS check.

If you don’t meet every requirement but feel you could thrive in this role, we would still encourage you to .

Gamma is an equal-opportunity employer committed to building diverse, inclusive teams where everyone feels valued and can be their authentic selves. We welcome applicants from all backgrounds, especially those underrepresented in our industry. As a family-friendly employer, we foster a culture of trust, autonomy, and flexibility to support your work-life balance and help you thrive at Gamma.

For recruitment agencies – we have a network of fantastic partners that support us in our hiring from time to time. We’re not looking to increase that network currently, so please don’t send speculative CVs.
