You are the giant slayers who have shaped Littlefish into the business it is today—and now, we’re looking for the next wave of internal trailblazers to help us take things even further. 

We’re seeking individuals who embrace change with optimism, who think beyond the obvious, and who bring energy, curiosity, and collaboration to everything they do.

We’re hiring for a Cyber Security Engineer to join our Cyber Services Division. If you enjoy taking ownership, solving complex challenges, and making a measurable impact on customer security, this could be the role for you. 

As our Cyber Security Engineer, you’ll play a key part in supporting and evolving our security tooling, especially our SIEM platform. You’ll work directly with both internal teams and customers to ensure strong security outcomes across the board. 

You will:  

• Take ownership of SOC tooling, with a primary focus on our SIEM platform.
• Implement SIEM solutions into customer environments and tune data feeds effectively.
• Work closely with the SOC to maintain and continuously improve SIEM rulesets and use cases.
• Provide expert cyber guidance and technical leadership to customers.
• Support major security incidents and play a hands on role in investigation and response.
• Deliver cyber led project work, independently or as part of wider Professional Services engagements.
• Stay ahead of emerging technologies and contribute to future security tooling roadmaps. 

Who you are: 

You’re confident, curious, collaborative, and passionate about improving security for customers and colleagues alike. You thrive in a role where you can influence decisions and deliver real value. 

You will bring: 

• Strong understanding of SIEM tools and attacker behaviours.
• Handson experience with O365, M365 and Azure security administration.
• PowerShell scripting capability.

• The ability to explain complex concepts clearly to both technical and nontechnical audiences.
• The ability to turn policy or regulatory requirements into meaningful technical solutions.
• Experience writing technical design documents.

• Azure Sentinel, AlienVault, AWS or GCP security controls.
• Linux, data storage, or scripting in Python or Bash.
