About the Role
VAPT Engineers sit within the 2nd-line CISO organisation at Ryt Bank, providing independent penetration testing and vulnerability assessment capability that is structurally separate from the 1st-line security function.
This role is for security professionals who are genuinely passionate about offensive security — finding vulnerabilities before adversaries do and helping Ryt Bank understand its real attack surface as an AI-powered digital bank.
What You'll Do
PENETRATION TESTING & VAPT
- Plan and execute quarterly vulnerability assessments across the bank's full infrastructure, applications, and API surface. Sr VAPT Engineers own and lead the programme; VAPT Engineers execute assessments and triage findings.
- Coordinate the annual intelligence-led penetration test covering internal network, external perimeter, applications, and APIs. Sr VAPT Engineers scope, manage, and validate; VAPT Engineers support execution.
- Lead the bank's triennial red team simulation — intelligence-led, adversary-simulated exercises targeting critical banking systems. Sr VAPT Engineers lead; VAPT Engineers participate and develop skills.
- Manage the external penetration testing firm relationship — scoping, reviewing methodologies, validating findings, and ensuring remediation is tracked. Led by Sr VAPT Engineers.
AI RED TEAM
- Own the bank's AI red-team programme, testing the bank’s adopted large language models, RAG pipelines, MCP-connected agents, and agentic workflows.
- Apply MITRE ATLAS (v5.4.0) techniques to simulate AI-targeted attacks: model API reconnaissance, training data poisoning, model evasion, prompt injection, indirect prompt injection via RAG documents, and confused-deputy attacks in agent-to-agent workflows.
- Test against OWASP Mobile, API, Web and LLM Top 10 (2025 edition) — covering prompt injection, sensitive information disclosure, excessive agency, system prompt leakage, vector and embedding weaknesses, and AI supply chain risks.
- Use AI red-team tooling to run systematic adversarial evaluations of the bank's AI systems. Sr VAPT Engineers own the programme; VAPT Engineers execute specific test scenarios.
- Produce AI security findings reports and coordinate remediation with the Lead, Security Engineering.
REMEDIATION & REPORTING
- Run purple team exercises in collaboration with the Lead, Cyber Operations — testing detection coverage, validating SIEM rules, and improving SOC response playbooks.
- Produce clear, actionable pentest and AI red-team reports for technical and non-technical audiences — including executive summaries for the CISO and board.
- Track all findings to remediation within agreed SLAs; escalate unresolved critical findings through the CISO.
- Provide technical security consultancy to engineering teams on high-risk features, novel architectures, and AI system deployments.
What We're Seeking
EXPERIENCE
- 3–7 years in penetration testing, red teaming, or offensive security roles with demonstrated independent delivery.
- Proven experience scoping, leading, and reporting on mobile and web applications, API, network, and cloud penetration tests.
- Hands-on experience with mobile, API and web application penetration testing
- Deep familiarity with AI penetration testing and tooling — testing LLMs, RAG systems, or agentic AI architectures is a strong differentiator.
- Deep familiarity with MITRE ATLAS and OWASP Mobile, Web, API and LLM Top 10 attack frameworks.
- Experience managing external pentest vendors.
- Experience in regulated environments (banking, fintech, insurance, critical infrastructure) preferred.
SKILLS
- Proficiency with offensive security tools — Burp Suite, Metasploit, Nmap, and custom scripting.
- Sr VAPT Engineers: proficiency with AI vulnerability testing tools (PyRIT, garak, Promptfoo) and ability to produce board-ready findings reports.
- VAPT Engineers: growing proficiency across offensive tools and methodologies.
- Ability to communicate findings clearly to technical and non-technical audiences.
- Understanding how to scope and execute adversarial exercises safely in a live banking environment.
PREFERRED CERTIFICATIONS
- OSCP, OSCP+ OSEP, CREST CPSA or CRT (Sr VAPT Engineers); OSCP in progress (VAPT Engineers).
- GIAC GPEN, GWAPT, or GXPN.
- CompTIA PenTest+.
What We Value
- Revolutionary in our thinking.
- Innovative in our products, services and the way we work.
- Genuine in our intentions.
- Honourable in our actions.
- Tenacious in overcoming challenge.
