Security Engineer II (Defensive)

Job Summary: 

As a Security Engineer II on the Defensive Platform Builder track you will build hands on experience across secure software design and cloud native infrastructure defence working under the direction of senior and lead engineers. You will develop an automation first mindset within a high velocity fintech environment supporting the integration of security controls into our public cloud and GitLab CI/CD pipelines while building towards independent ownership of AppSec and CloudSec work.

Responsibilities and Tasks (in order of priority)

1. Secure SDLC & CI/CD Automation

• Support the integration of automated security requirements and validation tooling into engineering pipelines under the direction of senior team members.

• Help build and maintain internal tooling and automated controls that reduce reliance on manual security checkpoints.

2. Cloud & Infrastructure Hardening

• Work alongside SRE and DevOps teams on secure public cloud architecture running Infrastructure as Code security scans (for example Terraform) and supporting network isolation controls.

• Contribute to cloud Identity and Access Management reviews and help maintain Zero Trust boundaries within containerised environments such as Docker and Kubernetes.

3. AI Driven Security & Application Reviews

• Assist in configuring and running automated security review workflows that use LLM APIs for pull request analysis.

• Learn and apply technical controls that protect generative AI features against LLM specific risks such as prompt injection and insecure output handling.

• Support source code audits and API security reviews building towards independent ownership of more complex assessments over time.

4. Cross Functional Collaboration & Development

• Take part in software development and infrastructure sprint planning to build a practical understanding of how security fits into the wider engineering lifecycle.

• Provide clear actionable feedback on code and configuration issues under the guidance of senior and lead engineers.

• Actively seek mentorship from senior and lead security engineers to develop breadth across the wider security function.

Qualifications :

• Education: Bachelors degree in Computer Science Cyber Security Software Engineering or a related technical discipline or equivalent practical experience.

• Core Experience:  indicative range 1 to 3 years of hands on experience in application or cloud security software engineering or a closely related technical role.

Highly Preferred Certifications

• Cloud & Architecture: AWS Certified Security - Specialty Certified Kubernetes Security Specialist (CKS) or CISSP.

• Modern AI Security: OffSec OSAI (Offensive Security AI Red Teamer).

• Broader Depth: OSCP or GCIH where candidates bring exposure to offensive or incident response work as a secondary strength.

Skills and Abilities

• Balances a builders engineering empathy with a security first mindset treating software SRE and product teams as operational allies rather than a source of friction.

• Communicates clearly under pressure able to distill cloud configuration drift or a live vulnerability into a plain high impact risk summary for non-technical stakeholders.

• Shows creative novel problem solving across complex non-standard application and cloud infrastructure challenges within a distributed financial microservices environment.

• Resilience and analytical clarity in high-pressure scenarios supporting transparent communication and contributing to risk-based decisions during active security incidents or compressed financial product launch windows.

• Balances technical risk reduction with business enablement supporting security infrastructure that serves as a competitive advantage and helps unblock global revenue and enterprise-client acquisition.
