You'll be joining our Platform Security Engineering team – a group of smart, talented engineers who make sure every application LEAP builds is secure.
Day to day, you'll work alongside LEAP engineering teams to secure our applications, hunt down vulnerabilities, and help strengthen our software development lifecycle.

To make this happen, you will:

Red Teaming, threat modelling and code reviews
Create detailed vulnerability reports and share them with key stakeholders
Communicate findings and recommendations clearly and effectively
Track vulnerability remediation
Conduct threat modelling sessions with internal development teams
Coordinate third‐party penetration tests and support compliance and audit requirements
What You'll Bring
Bachelor's degree in IT or a related field
Pentesting certifications will be highly regarded (OSCP, OSCP+, CRTO, CRTP, GPEN, etc.)




Broad testing background across web applications, APIs, internal and external infrastructure
Experience producing structured penetration test reports that demonstrate the attack path with supporting evidence, business impact and detailed remediation advice
It would be a bonus if you've worked with tech, SaaS or startup companies
Ability to approach complex problems with creativity and critical thinking
Excellent time‐management skills with the ability to prioritise tasks and manage multiple competing priorities
