We provide voice, data, and mobile solutions to businesses across the UK, Germany, Spain, and the Benelux region, and we’re expanding rapidly to bring digital automation and Gamma-powered services to SMEs through a growing network of channel partners.

Our team thrives on collaboration, innovation, and the belief that diverse perspectives make us stronger. Join us, and you’ll have the opportunity to make an impact, grow your career, and be part of a company that celebrates inclusivity and fresh ideas.

Who are we looking for?

Are you passionate about cybersecurity and looking to take the next step in your career? We’re looking for a Tier 2 Cyber Security Analyst to join our fast-paced and supportive Security Operations Centre (SOC) team.

You'll play a vital role in detecting and resolving security incidents for our customers—collaborating closely with your teammates and staying ahead of emerging threats. Whether you’re deep-diving into technical investigations, supporting more junior analysts, or helping customers understand how to improve their security, you’ll be part of a team that protects, empowers and grows together.

What will you be doing day-to-day? 

• Monitor and analyse security alerts using SIEM and other tools, investigating threats and supporting escalations from Tier 1 Analysts.
• Proactively identify anomalous behaviour and carry out threat hunts to uncover potential risks.
• Research and document new vulnerability disclosures, helping communicate insights clearly across the business and to customers.
• Triage, escalate, and resolve security incidents—making sure customers receive timely updates and support.
• Provide guidance to customers and internal teams in a way that's clear, collaborative, and easy to understand.
• Support security tool tuning and development of new use cases to improve proactive threat detection.
• Keep clear records of investigations, actions and outcomes in line with our processes.
• Contribute to knowledge-sharing and process improvement across the SOC.
• Stay up to date with the latest cyber security trends, tools and techniques—and share your insights with the team.
  
  
  

What you’ll need:

We don’t expect you to tick every single box—but you’ll thrive in this role if you:

• Have experience working in a SOC or similar security operations environment
• Know your way around tools like SIEM, firewalls, endpoint protection, IDS/IPS, antivirus etc.
• Understand networking principles (TCP/IP, OSI model, common ports, VPNs)
• Are confident investigating incidents and writing clear, actionable reports
• Understand best practices in cloud security (especially hybrid environments)
• Know the common frameworks like ISO 27001, PCI DSS, NIST, GDPR
• Are collaborative, solution-focused, and genuinely enjoy supporting others
• Have strong communication skills, especially when simplifying technical language
• Are curious, proactive, and enjoy learning and adapting in a fast-moving industry
• Have a degree in Cyber Security, Computer Science or similar (or equivalent experience)
• Have industry certifications such as CompTIA CySA+, CEH, Microsoft SC-200
  
  
  

Due to the sensitivity of the role, you will also need to go through (and pass) security clearance.

What do we offer you? 

• At Gamma, we believe in work-life balance, which is why we offer 25 days of annual leave (adjusted due to nature of the role), plus an extra day off for your birthday.
• Giving back is important to us, so we also provide a volunteer day to support a charity that matters to you.
• Family matters, too. With enhanced maternity and paternity pay, we’re here to support you as a parent and help you thrive in your career.
• We offer a contributory pension plan to help you save for the years ahead, with Gamma’s contribution varying dependant on yours.
• Your well-being is our priority. We offer group income protection and life assurance (four times your salary) to ensure peace of mind for you and your loved ones.
• We want you to share in our success. That’s why we offer tax-efficient share save and share incentive plans, giving you the opportunity to benefit from Gamma’s growth.
• We’re committed to health, both physical and mental, and provide private medical insurance through Vitality, which extends to your immediate family..
• And, because we care about the environment, we offer an Electric Vehicle scheme through Octopus and a Cycle to Work scheme, making it easier to get around sustainably.
  
  
  

A few things to note 

• Unfortunately, we can't offer visa sponsorship or relocation support for this role.
• This role is hybrid from our Luton office.
• As our SOC Team works 24/7/365, you will need to be available to work evenings/nights, weekends and bank holidays.
• If you feel you could be a good fit for Gamma but do not think that you meet all the requirements, we still encourage you to apply as you could be the person that we are looking for!
