Job Title: Senior Applied AI Engineer Team: Global Quality Engineering Location: New York City, Los Angeles, San Francisco   Overview Paramount Skydance Corp. is seeking a Senior Applied AI Engineer to architect, build, and operationalize AI-driven solutions that transform how we deliver software quality across the enterprise. This role blends advanced machine learning, large language models, and software engineering expertise to improve automation efficiency, accelerate feedback loops, enhance defect detection, and deliver predictive quality insights. You will be a key member of the Global Quality Engineering (GQE) team and partner with DevOps, SRE, and Infosec teams to embed AI capabilities directly into the SDLC, leveraging modern platforms such as Vertex AI to deliver scalable, resilient, and impactful AI solutions for Quality Engineering initiatives.   Key Responsibilities   AI/ML Solution Development ● Architect, develop, and deploy end-to-end AI/ML systems addressing key QE workflows (e.g., bug prediction, app confidence scoring for incremental releases, flaky test detection, intelligent test prioritization, anomaly detection). ● Build, optimize, and tune RAG pipelines, including:     o embedding and vector store selection     o chunking and retrieval optimization     o hallucination mitigation and grounding techniques     o hybrid LLM architectures ● Perform LLM fine-tuning (full-model, LoRA/QLoRA, instruction tuning) and determine when fine-tuning is appropriate vs. RAG-only or hybrid approaches. ● Build LLM tools for:     o test case generation (manual and automated)     o synthetic test data creation     o log and telemetry summarization     o automated triage and quality insights ● Develop model evaluation frameworks ensuring accuracy, robustness, and safe behavior over time.   Global Quality Engineering Innovation ● Identify and prioritize opportunities to integrate AI automation across test strategy, execution, triage, and release decisioning. ● Integrate AI into CI/CD pipelines for dynamic risk-based testing, anomaly detection, and intelligent quality gates. ● Build solutions that analyze logs, traces, telemetry, and user signals to detect emerging quality risks.   Cloud & Platform Engineering (Vertex AI) ● Leverage Google Cloud Vertex AI to build scalable, production-grade AI systems, including:     o Model Garden     o Vertex AI Training, Tuning (LoRA/QLoRA), and Custom Jobs     o Vertex AI Vector Search for high-performance retrieval     o Vertex AI Pipelines for automated ML workflows     o Vertex AI Online Endpoints for real-time inference ● Integrate Vertex AI with GCP services (BigQuery, Cloud Run, GKE, Pub/Sub) for full production deployment.   Technical Leadership ● Lead architectural decisions on LLM system design, MLOps, data pipelines, and monitoring strategies. ● Mentor engineers on applied ML, modern AI development, prompt engineering, and RAG-vs-fine-tuning tradeoffs. ● Partner in the creation of engineering standards for model governance, safety, code quality, and scalable AI development.   Cross-Functional Collaboration ● Collaborate with peers in GQE as well as DevOps, SRE and Infosec teams to translate quality challenges into high-value AI solutions that accelerate testing. ● Work closely with Data Engineering to ensure training data quality, governance, privacy, and compliance. ● Clearly communicate complex concepts to a variety of audiences including executives, engineers, and non-technical stakeholders.   Required Qualifications ● 7+ years of experience in machine learning engineering, software engineering, or applied AI. ● Strong expertise in Java, Python, PyTorch/TensorFlow, and modern LLM tooling. ● Deep hands-on experience with RAG systems, including:     o vector database design and embedding evaluation     o retrieval optimization and hybrid architectures     o hal
