AI Security Researcher

The role

You will find, study and fix security threats to Apollo's internal systems, including new risks from AI agents. You will red-team software, infrastructure and agent access controls, and turn findings into deployed fixes and controls.

What you will do

• Hold responsibility for the security of Apollo's internal surfaces.
• Red-team internal software, infrastructure, and AI agent access controls and monitoring.
• Build realistic attack trajectories.
• Design solutions for novel or emerging threats in AI security.
• Track adversary tactics, techniques, and campaigns, and turn that into tuned detections.
• Own each finding through to a deployed fix.
• Build and roll out durable controls: checks, tests, defaults, detections.
• Work with engineers to implement controls and hold remediation to a high bar.

Required qualifications

• 5+ years in security roles in a hands-on technical capacity (not purely GRC/compliance).
• Ability to think structurally about threat modelling and failure modes.
• Ability to read code, understand infrastructure, and evaluate technical controls.
• Direct experience with offensive security: threat modelling, red teaming.
• Knowledge of application or cloud security.
• Engineering mindset: treat security as an engineering problem and translate findings into fixes and controls.
• Comfortable with startup pace, ambiguity and changing priorities.
• Strong written communication.

Nice to have

• Experience with AI/ML systems security or LLM security.
• Detection engineering, SOC, or incident analysis experience.
• Familiarity with insider threat programs or insider risk frameworks.

Benefits

• Market competitive salary and equity.
• Engineers have an effectively unlimited token budget.
• Flexible work hours and schedule.
• Unlimited vacation.
• Unlimited sick leave.
• Up to 6 months of paid parental leave.
• Comprehensive health, dental and vision insurance.
• Retirement savings with employer matching (e.g. 401(k) for US employees).
• Lunch, dinner, and snacks provided on workdays.
• Paid work trips, including staff retreats, business trips, and conferences.
• $1,000 (USD) yearly professional development budget.
• Relocation support and visa fees (if applicable).

Before you apply

• Visa sponsorship is offered in the UK and US, but not guaranteed for every role or candidate.
• Multi-stage process: screening interview, take-home test (about 2-3 hours), 3 technical interviews, and a final interview with the CEO.
• No LeetCode-style general coding interviews.
• AI tools may be used on the take-home test; the candidate is responsible for the quality of submitted work.
• Resumes are screened by AI-powered tools, but a human reviews all resumes and makes final hiring decisions.
