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 Software Engineer to design, build, and maintain software solutions across Gamma’s product and service portfolio.
In this role, you’ll contribute to the design and development of internal tooling applications focused on monitoring, diagnostics, reporting, and data processing. You’ll work closely with product, operational, and engineering teams to ensure systems are scalable, observable, and aligned with Gamma’s architectural standards.
This is an opportunity for someone who thrives on solving complex, open‑ended problems and wants to make a measurable impact through high‑quality engineering.
What will you be doing day‑to‑day?
- Design software systems that meet defined objectives and architectural standards
- Develop and maintain internal tooling applications for monitoring, diagnostics, and reporting
- Implement robust back‑end services and components underpinning these systems
- Collaboratively design and define APIs (local libraries and remote services)
- Ensure software is testable at all levels and implement automated testing strategies to minimise regression risk
- Integrate solutions into existing CI/CD pipelines, or create new pipelines where required
- Facilitate technical design discussions, document Architecture Decision Records (ADRs), and maintain high‑quality technical documentation
- Follow Gamma architecture recommendations and team conventions, contributing to their evolution
- Contribute to defining and delivering the team’s technical roadmap
- Work closely with production and operational teams to understand domain‑specific data and optimise how it is consumed, processed, cached, and presented
- Ensure systems are observable through appropriate metrics, monitoring, and alerting integrations
- Provide technical input to customer support teams regarding incidents and potential user‑impacting changes

- SIP and RTP knowledge (beneficial)
- Engineering capability
- Expert‑level problem‑solving skills, particularly with ambiguous or open‑ended challenges
- Ability to conduct root cause analysis and proactively identify technical risks
- Experience refactoring code for testability, scalability, and maintainability
- Strong decision‑making skills, balancing abstraction, complexity, and future change
- Ability to contribute to scoping decisions with estimation and risk analysis
- Experience integrating monitoring, metrics, and alerting into systems
Collaboration & Leadership Behaviours
