Nowadays, we're on the hunt for a hands-on and security-focused Information Security Engineer!
At Casumo, we’re building a secure, scalable, and forward-thinking digital environment - and we’re looking for an Information Security Engineer to help us do it.
In this role, you’ll work at the intersection of engineering and security, embedding best practices into our systems, products, and processes.

Conduct code reviews, threat modelling, and architecture assessments to strengthen system security.
Identify and remediate vulnerabilities across applications, APIs, and services.
Partner with development teams to promote and improve secure coding practices.
Support and optimise application security tools (e.g. SAST, DAST, dependency scanning).
Help secure cloud-native and distributed systems at scale.
Take ownership of reducing security debt—working with engineers to design, track, and implement effective fixes.
Act as an escalation point for security incidents identified by our managed SOC.
Lead or support incident response, investigation, and remediation efforts.
Collaborate with SOC providers to enhance detection and response capabilities.
Contribute to maintaining security frameworks such as ISO 27001 and PCI DSS.
Support audits and regulatory requirements as needed.
Maintain and improve security documentation, policies, and technical standards.
Champion security best practices across the organisation through training and collaboration.
Translate complex security concepts into clear, practical guidance for engineers and stakeholders.
Stay up to date with emerging threats, vulnerabilities, and industry trends.
Degree in Computer Science, Software Engineering, or equivalent practical experience.
Around 3–6 years of experience in software engineering, security engineering, or a related field.
Hands-on experience securing modern applications and distributed systems.
Strong understanding of:
Application security principles and common vulnerabilities (e.g. OWASP Top 10).
Authentication, authorisation, and security protocols.
Applied cryptography fundamentals.
Experience with one or more programming languages such as:
JavaScript (essential for modern web applications).
Python, Java, C/C++, PHP or similar.
Ability to read, write, and review code from a security perspective.
Familiarity with cloud environments, APIs, and microservices architectures.
Experience defending against real-world attack vectors across multiple domains.
Understanding of endpoint, network, and application security.
Exposure to vulnerability management and security testing practices.
Security certifications (e.g. CompTIA Security+, CySA+, AWS Certified Security – Specialty, Google Cloud Professional Cloud Security Engineer).
Experience working with ISO/IEC 27001 or PCI DSS environments.
Experience collaborating with or operating alongside a managed SOC.
Familiarity with security tooling (e.g. Cloudflare, SAST/DAST tools).
Experience with Infrastructure as Code (Terraform, CloudFormation) and container security (Docker, Kubernetes).
A pragmatic security engineer who balances risk with business needs.
