What You’ll Do

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.

- 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
