TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
This Senior Full Stack Software Engineer role is crucial for operationalizing Keysight's AI Labs strategy, serving as the connective tissue between foundational machine learning research and commercial-grade quantum, 6G, and semiconductor validation platforms. The function elevates research-grade AI/ML models—including generative AI applications—from experimental environments into high-reliability, cloud-native production systems. By building and securing the underlying full-stack infrastructure, this position directly enables the scalable deployment of physics-informed AI, transforming the efficiency and accessibility of advanced test and measurement workflows across critical technology sectors.
The primary constraint impacting the immediate utility of AI/ML within the deep-tech test and measurement value chain is the MLOps gap: translating specialized models optimized for specific physical domains (e.g., quantum control, RF signal processing) into continuously reliable, low-latency, and globally available software services. Traditional software engineering expertise, especially full-stack capability focused on robustness and scalability, is the key workforce gap that prevents R&D breakthroughs from reaching market-ready TRLs (Technology Readiness Levels). In the current vendor landscape, platforms like Keysight must integrate AI to maintain differentiation, moving beyond hardware-centric offerings to providing intelligent, predictive design and validation environments. This role addresses the inherent complexity of integrating high-dimensional data, complex domain-specific models, and secure, multi-tenant cloud infrastructure (AWS, Azure, GCP). By establishing strong, secure, and observable production endpoints, this engineer mitigates the technical risk associated with deploying novel AI applications to demanding, mission-critical engineering customers, accelerating the maturity of integrated quantum and 6G technologies.
The technical skill architecture centers on delivering high-availability and high-throughput application delivery. Expertise in backend languages (Python, Java, Node.js, C#) is leveraged to develop performant, logically segregated microservices and robust RESTful APIs, ensuring efficient data exchange and model serving. Frontend mastery (React/Angular/Vue) ensures that complex, high-signal data visualizations derived from AI models are delivered via intuitive, responsive user interfaces, maximizing user adoption and data accessibility. Crucially, demonstrated proficiency in DevSecOps practices, including CI/CD pipelines, Docker, and Infrastructure-as-Code (Terraform), translates directly into system stability and accelerated deployment cycles. This fusion of full-stack development, cloud engineering, and foundational data integrity (SQL/NoSQL) establishes the necessary scaffolding for high-scale, secure, and compliant ML workflow orchestration that can reliably service a global R&D customer base. * Architecting a cloud-native delivery layer for physics-informed machine learning models used in quantum and advanced semiconductor design.
* Establishing codified best practices for security and compliance across the AI model lifecycle, protecting proprietary R\&D data.
* Accelerating the market penetration of Keysight’s generative AI and ML intellectual property into production measurement solutions.
* Mitigating latency and scaling constraints associated with deploying complex simulation and validation models globally.
* Enabling seamless integration of R\&D outputs with customer-facing platforms, collapsing the innovation cycle time.
* Standardizing data governance and modeling practices for high-volume, multi-domain engineering datasets (RF, EM, Quantum).
* Cultivating an MLOps culture that ensures model drift detection and continuous retraining are programmatically embedded.
* Enhancing the user experience (UX/UI) of scientific tools to improve the efficiency of non-expert AI users within engineering teams.
* Influencing architectural decisions for next-generation platform development across Keysight’s diverse technology portfolio.
* Providing mentorship that expands the foundational software engineering competency across the wider AI Labs R\&D group.
* Reducing operational expenditures through automated deployment, monitoring, and debugging in multi-cloud environments.
