Job Description

A bit about us
At Gamma, we’re more than just a leader in Unified Communications as a Service (UCaaS). We’re a fast-moving technology organisation delivering innovative voice, data, and mobile solutions across Europe.
Our product and service portfolio is at the heart of what we do — powering reliable, scalable communications for thousands of businesses. Behind the scenes, our engineering teams design, build, and maintain the software systems that generate real business impact.
We combine the agility of a start-up mindset with the stability of a leading European business. Collaboration, ownership, and continuous improvement define how we work — and we’re always looking for people who want to build meaningful technology at scale.
Who are we looking for?

We’re looking for a motivated and detail-oriented Software Engineer to support the design, development, and implementation of systems within the BSS/OSS domain. You’ll play a key role in delivering reliable, scalable solutions while building a strong understanding of both functional and non-functional requirements.
In this role, you’ll take ownership of technical implementations and continuously develop your expertise in areas such as system capacity, security, performance, and maintainability. You’ll work collaboratively with cross-functional teams to ensure high-quality, future-proof solutions.
What will you be doing day-to-day?
Your day-to-day responsibilities will include:
• Designing and implementing high-quality, maintainable code
• Reviewing code to ensure best practices, performance, and readability
• Writing and maintaining automated tests to ensure system reliability
• Contributing to and improving CI/CD pipelines for efficient delivery
• Participating in Agile ceremonies such as stand-ups, sprint planning, and retrospectives
• Supporting the implementation and integration of various systems across the BSS/OSS landscape
• Collaborating with team members to troubleshoot issues and continuously improve development processes
What you’ll need
To succeed in this role, you should have:
• Strong experience with Java (version 8 or above)
• Solid understanding of SQL and database design principles
• Familiarity with ReactJS for front-end development
• Working knowledge of PHP
• Understanding of industry best practices in automated testing
• Familiarity with CI/CD principles and tooling
• Experience working in Agile development environments
• Knowledge of public cloud platforms, ideally AWS
• Understanding of containerisation technologies (e.g. Docker) and orchestration tools such as Kubernetes
What do we offer you?
At Gamma, we believe in work–life balance, which is why we offer 25 days of annual leave, plus an extra day off for your birthday. We also provide a volunteer day, allowing you to support a cause that matters to you.
Family is important to us. With enhanced maternity and paternity pay, we support you at every stage of life. Our contributory pension scheme helps you plan for the future, with Gamma increasing contributions in line with yours.
Your wellbeing comes first. We offer group income protection, life assurance (four times your salary), and private medical insurance through Vitality, which extends to your immediate family.
We want you to share in our success, which is why we offer tax-efficient share save and share incentive plans.
We’re also committed to sustainability, offering an Electric Vehicle scheme through Octopus and a Cycle to Work scheme, making greener travel easier.
A few things to note
Unfortunately, we can’t offer visa sponsorship or relocation support for this role.
This role is hybrid, with office and home working flexibility.
If you feel you could be a great fit for Gamma but don’t meet every requirement, we still encourage you to apply — you might be exactly who we’re looking for.
