Job Description

Join BGSV by 31 December 2026 and receive a Joining Bonus equivalent to 1 month gross salary, subject to program eligibility and terms & conditions.

About the Role

We are looking for a Penetration Tester to join our AI Safety & Security team, working hands-on across Bosch's growing portfolio of AI-enabled products and internal tooling — LLM deployments, agentic AI systems, and Model Context Protocol – style tool-calling integrations. Under the direction of the team's Lead AI Safety & Security Engineer, you will execute structured test plans against real systems, covering both whether an AI system behaves safely (does it refuse harmful requests, stay within its intended scope) and whether it is secure (can it be manipulated via prompt injection or tricked into misusing its tools). This is an individual-contributor role on a newly forming team — you'll be running real engagements from day one, not just shadowing them.

Key Responsibilities

• Execute penetration tests and safety evaluations against LLM-based features and AI agents, following test plans and specifications defined by the team lead.
• Run red-teaming and jailbreak testing to surface harmful, biased, or unsafe model outputs, and document reproducible findings.
• Test for prompt injection (direct and indirect), excessive agency, and tool/plugin abuse in agentic and MCP-style tool-calling systems.
• Verify human-in-the-loop and guardrail controls hold up under adversarial conditions, not just in normal use.
• Write clear, reproducible findings reports — evidence, severity, and a specific recommended fix — that both engineers and governance stakeholders can act on.
• Help build and maintain test tooling: adversarial-prompt scripts, jailbreak test cases, and MCP/tool-schema fuzzing scripts.
• Track published AI security research (OWASP LLM and Agentic Top 10s, MITRE ATLAS) and bring new attack techniques into the team's test suite.
• Work directly with AI/ML engineering teams to reproduce, triage, and confirm fixes for reported findings.
• Support the team lead in scoping and coordinating external red-teaming/pentest vendor engagements when work is outsourced.

Qualifications

Required Qualifications

• Bachelor's degree in Computer Science, Machine Learning, or a related field.
• 2–5 years in penetration testing, security testing, or applied AI/ML security work.
• Hands-on experience testing LLM or agentic AI systems — prompt injection, jailbreaks, or tool/plugin abuse; coursework, CTFs, or independent projects count given how new this field is.
• Working familiarity with the OWASP Top 10 for LLM Applications and/or OWASP Top 10 for Agentic Applications.
• Comfortable scripting in Python and/or JavaScript/Node to automate test cases.
• Clear, precise technical writing for findings reports.

Preferred Qualifications

• Exposure to the Model Context Protocol (MCP) or comparable agent tool-calling frameworks.
• Traditional penetration testing experience across web, API, or network targets.
• Familiarity with AI governance concepts (NIST AI RMF, ISO/IEC 42001, EU AI Act).
• Open-source security tooling contributions, CTF results, or a public research/write-up portfolio.

Relevant Certifications (any of the following a plus)

• Offensive security / penetration testing — OSCP, GPEN, GWAPT, or CEH.
• AI-specific security — ISC2 AI Security Certificate or Certified AI Security Professional (CAISP).
