Principal Software Engineer – Knowledge Graph & Semantic Layer

Help us build the "System of Action" that supercharges global manufacturing teams.  QAD is entering a high-velocity era to architect the world’s first AI-native, agentic ERP. We are moving beyond legacy "systems of record" to build an autonomous platform where humans and AI work as a tag team to redefine how factories operate.  Join us at this pivotal moment to build our next generation platform, lead the next generation of the Adaptive Enterprise and turn global speed into strategy.  

Ignite Your Future

Are you a visionary Principal Software Engineer ready to define and drive the technical strategy for an entire function, own complex, high-impact systems, and directly contribute to the future of intelligent manufacturing? Join QAD, where we are redefining the supply chain through our intelligent, adaptive platform—a single System of Action that connects people, processes, and data. As a Sr. Principal Software Engineer, you will be a key technical leader responsible for the architecture, governance, and delivery of our enterprise-scale SaaS products, operating with Champion Pace. You will be a recognized internal subject matter expert, focusing on providing thought leadership across the organization.

The Mission: What You'll Be Building

You will be the core driver in the conceptualization, design, development, and implementation of new, highly complex models and procedures. You will provide strategic technical direction, mentor senior and principal team members, and leverage broad expertise in highly specialized fields to develop solutions in cloud-native architectures, microservices, and Agile product development. You will be instrumental in building the next generation of our platform

Technical authority for encoding manufacturing knowledge into ERA — the graph and ontology layer that makes ERA's AI defensible.

Your Impact/ What you will be doing: 

• Design the ERA Knowledge Graph schema: entity types, relationship definitions, and property graph architecture

• Define manufacturing domain ontologies — formal representations of ERP concepts agents can reason over

• Own query performance for knowledge retrieval — agent response latency depends on your design

• Lead entity resolution, entity lineage tracking, and context assembly strategy

• Set the technical standard for semantic modeling across the Intelligence sub-team

Required Skills & Qualifications

• 10+ years in data or AI engineering; expert in graph databases and semantic modeling

• Production-grade Neo4j, Amazon Neptune, or equivalent graph DB experience (schema, Cypher/SPARQL, performance)

• Semantic modeling depth: RDF/OWL ontologies, entity resolution, and lineage tracking

• Experience building data products consumed by AI/ML or agent systems

• Hybrid search experience: vector + graph retrieval

• LLM grounding techniques: retrieval-augmented generation with knowledge graph context

• Manufacturing or ERP domain familiarity

The Mindset:

• Strategic Problem Solver: Strong logical thinking and problem-solving abilities. Exercises independent judgment in selecting methods, techniques and evaluation criteria for obtaining results. Capable of driving functional solutions end-to-end and influencing technology choices.

• Adaptability: Eagerness to quickly learn and adopt cutting-edge technologies. Understands and works on highly complex issues where analysis of situations or data requires an in-depth evaluation of variable factors.

• Ownership & Quality: A detail-oriented mindset with a focus on quality, demonstrating end-to-end responsibility for architectural components and their impact on the entire function.

• Proactive Leader: Takes initiative to anticipate and address future needs, risks, or improvements without explicit direction, establishing new standards where necessary.

• Quick Learner: Demonstrates a rapid capacity to grasp new technologies, complex systems, and development methodologies.
