About the Role

We’re looking for a Senior Cybersecurity Engineer to join our Security team and take ownership of building Linkly’s internal penetration testing capability. This is a brand-new function in the team, so you will be building it from the ground up.

This role requires deep technical cloud security expertise, with Azure as our primary platform. You’ll work closely with our Chief Security Officer, the wider Security team, and our engineering and operations teams to validate that the design and configuration of our products and services meet security requirements. Engineering owns the design; you make sure it holds up.

Within your first 12 months, you’ll have an internal penetration testing function in place and in use, security assessments of cloud infrastructure changes running routinely, and a defined set of security guidelines and baselines for the business.

Key Responsibilities

- Build and run Linkly’s internal penetration testing function, carrying out testing across our cloud infrastructure, products and services.

- Carry out security assessments of current changes to our cloud infrastructure.

- Consult with engineering teams and validate and test that the design and configuration of their products and services are secure and meet security requirements.

- Help set Linkly’s security guidelines and define the security baselines our cloud environments are built and measured against.

- Provide security design review and testing for upcoming initiatives, including our new data product.

What You'll Need





- 6+ years’ experience as a security engineer, penetration tester or security consultant.
- Hands-on penetration testing experience.
- Deep, detailed technical knowledge of Microsoft Azure, including cloud-native attack techniques and common misconfigurations.
- Experience with secure cloud architecture, particularly on Azure.
- Experience developing threat models and helping engineering teams reason through different ways to reduce security risk.
- Scripting or programming skills (e.g. Python or PowerShell) to automate testing and build your own tooling.
- Ability to write clear, concise reports covering findings, risks and practical remediation recommendations.
- Strong communication skills, with the ability to explain technical security concepts to both technical and non-technical audiences.

Nice to Have:

- AWS experience, including secure cloud architecture on AWS.

- Certified Ethical Hacker (CEH) or an equivalent certification.

- Exposure to PCI DSS and the payments industry.

Our Values

- Act Like an Owner: Take full accountability for outcomes and make decisions with the long-term success of Linkly in mind.
- Innovate: Challenge assumptions, champion new ideas and drive meaningful change for customers and the business.
- Deepen Trust: Build confidence through integrity, transparency and consistent delivery with your team, partners and clients.
- Care and Respect: Foster an inclusive, supportive environment where everyone feels valued and empowered to do their best work.
