Staff Software Development Engineer (LLM)

Job Responsibilities:

1. Architect and implement functions to monitor and filter LLM requests/responses in real time preventing prompt injection attacks and unauthorized data leakage.
2. Build a highly scalable pipeline capable of handling high-volume LLM traffic with low latency including optimizing databases and caching for quick threat detection and response.
3. Develop monitoring logging and alerting systems to detect anomalies in LLM usage (e.g. suspicious spikes indicating denial-of-service attacks or unusual prompt patterns indicating misuse).
4. Collaborate with teams to translate security requirements into platform features. Mentor junior engineers on secure backend development and best practices in an Agile environment.
5. Ensure the timely delivery of high-quality software features while adhering to project schedules.
6. Communicate effectively across teams with both technical and non-technical stakeholders in both verbal and written forms.

Job requirements:

1. Hands-on experience with deploying or integrating large language models or other AI/ML systems (e.g. implementing model inference pipelines fine-tuning models or working with LLM APIs and prompt handling). Strong understanding of how prompts and context are managed in LLM applications.
2. Solid knowledge of application security principles and experience building secure systems. Familiarity with AI-specific threats (prompt injection data poisoning output manipulation) and a keen interest in staying ahead of new generative AI attack vectors.
3. Proven experience designing microservices architectures and using containerization (Docker) and orchestration (Kubernetes). Comfortable with cloud platforms (AWS GCP or Azure) and designing observable resilient services in a production environment.
4. Ability to design clean efficient and secure APIs. Strong understanding of network protocols data caching and performance optimization.
5. Knowledge of data protection and privacy best practices able to design systems that handle sensitive data responsibly and comply with regulations. Understanding of responsible AI principles (ethics bias transparency) and how they relate to secure AI system design.
6. Familiarity with emerging AI security guidelines such as OWASPs Top 10 for LLMs/Generative AI Security (e.g. knowledge of prompt injection insecure output handling data poisoning risks) and experience implementing related mitigations.
7. Experience with retrieval-augmented generation (RAG) architectures vector databases/embedding stores or streaming data pipelines for ML especially as they relate to monitoring and securing LLM workflows (helps in addressing vector embedding attack vulnerabilities).
8. Understanding of responsible AI and techniques for detecting AI-generated misinformation or hallucinations. Experience building or integrating content filtering policy enforcement or fact-checking systems in AI applications is a plus.
9. Strong programming and debugging skills particularly in Python and C/C.
10. Familiarity with Frameworks like PyTorch or TensorFlow for model integration; libraries such as Hugging Face Transformers or LangChain for LLM and prompt management; LLM APIs (OpenAI etc.) and vector databases is beneficial.
