Senior Applied AI Engineer

Job Title

Senior Applied AI Engineer

Global Quality Engineering

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 Dev Ops, 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.

• 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 embedding and vector store selection, chunking and retrieval optimization, hallucination mitigation and grounding techniques, and hybrid LLM architectures.
• Perform LLM fine-tuning (full-model, LoRA/QLoRA, instruction tuning) and determine when fine-tuning is appropriate versus RAG-only or hybrid approaches.
• Build LLM tools for test case generation (manual and automated), synthetic test data creation, log and telemetry summarization, and automated triage and quality insights.
• Develop model evaluation frameworks ensuring accuracy, robustness, and safe behavior over time.

• 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.
• Leverage Google Cloud Vertex AI to build scalable, production-grade AI systems, including Vertex AI Training, Tuning (LoRA/QLoRA), and Custom Jobs;
  Vertex AI Vector Search for high-performance retrieval;
  Vertex AI Pipelines for automated ML workflows;
  Vertex AI Online Endpoints for real-time inference.
• Integrate Vertex AI with GCP services (Big Query, Cloud Run, GKE, Pub/Sub) for full production deployment.

• 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.

• Collaborate with peers in GQE as well as Dev Ops, 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.

• 7+ years of experience in machine learning engineering, software engineering, or applied AI.
• Strong expertise in Java, Python, PyTorch/Tensor Flow, and modern LLM tooling.
• Deep hands-on experience with RAG systems, including vector database design and embedding evaluation, retrieval optimization and hybrid architectures, hallucination reduction and grounding strategies.
• Strong hands-on experience with LLM fine-tuning, including full-model and parameter-efficient approaches, cost, latency, and behavior tradeoff analysis.
• Expertise selecting between RAG vs. fine-tuning vs. hybrid approaches based on data characteristics, quality needs, and business constraints.
• Production experience with Google Cloud Vertex AI, including training, tuning, pipelines, Vector Search, and real-time model deployment.
• Solid understanding of quality engineering tools, automation frameworks…
