AI Security Engineer

AI Threat Modelling and Security Architecture

• Guide application and platform teams on threat modelling for AI and LLM-based systems across the full lifecycle
• Develop and maintain AI-specific threat models aligned to recognised standards and regulatory expectations
• Translate threat models into explicit architectural controls security requirements and acceptance criteria
• Advise on secure AI design patterns including least-privilege isolation and human-in-the-loop safeguards

Secure Implementation and Runtime Enforcement

• Work closely with AI and ML engineers to ensure secure implementation of AI guardrails within application codebases
• Ensure robust input sanitisation validation and prompt hardening for text document and multimodal inputs
• Ensure output validation redaction and data exfiltration prevention mechanisms are correctly implemented
• Evaluate test and support deployment of LLM security frameworks and detection mechanisms
• Ensure security-relevant telemetry and logs are captured in line with regulatory and audit requirements

AI Security Observability and SOC Integration

• Define and publish AI-specific security indicators for operational monitoring and alerting
• Enable real-time visibility into AI security signals such as anomalous behaviour prompt abuse or tool misuse
• Support downstream security operations and incident response teams with actionable AI security context

AI Red Teaming and Offensive Security Integration

• Embed automated AI security testing into CI/CD pipelines including prompt fuzzing and regression testing
• Support and guide offensive security teams on LLM-specific attack scenarios
• Operationalise AI red-teaming tools and custom adversarial test cases
• Ensure findings feed back into guardrail tuning detection logic and adaptive defence mechanisms

Required Qualifications

Core Experience

• Strong background in application development security engineering or platform engineering
• Practical experience working with AI-enabled applications LLMs or ML pipelines
• Solid grounding in application security concepts and secure software design
• Hands-on experience implementing or integrating AI guardrails sanitisation and runtime security controls

AI and Security Capability

• Practical understanding of AI and LLM threat vectors such as prompt injection data poisoning tool abuse and agent escalation
• Experience collaborating closely with AI engineers platform teams and offensive security practitioners
• Ability to translate security intent into concrete testable engineering controls

Advantageous but Not Mandatory

• Experience with AI red-teaming tools or adversarial testing frameworks
• Familiarity with secure CI/CD and DevSecOps practices
• Experience operating in regulated or highly governed enterprise environments
• Exposure to SOC integration detection engineering or security observability

Why Work for SentraAI

• Enterprise AI done properly.
  We exist to take AI and data out of experimentation and into production environments that are regulated scrutinised and expected to work every day.
• Quality is not optional.
  SentraAI is built on the belief that engineering discipline governance by design and delivery rigour are competitive advantages not overhead.
• Clear ownership and accountability.
  You will be trusted with real responsibility clear mandates and meaningful outcomes not diluted roles or performative activity.
• Work that survives contact with reality.
  We design systems operating models and decisions that still stand up months and years after go-live not just at demo time.
• Run-state matters as much as build-state.
  We optimise for operability auditability and change control from day one because that is where enterprise value is won or lost.
• Substance over hype.
  We deliberately avoid delivery theatre buzzwords and novelty for noveltys sake. Credibility is earned through execution.
• Learn from experienced practitioners.
  You will work alongside people who have built broken fixed and run enterprise systems and who care deeply about doing the work properly.
• A firm with a point of view.
  SentraAI is opinionated by design. We stand for doing fewer things better and we expect our people to take pride in that standard.
