Senior/Principal Lead Delivery Engineer — Industrial

Full-time position | San Mateo, CA (Onsite)

Luminary helps engineering companies be more competitive by getting to market faster, creating better products, and reducing development risk. We do this through our Physics AI platform — the fastest and easiest way to build and deploy models that understand and instantly predict physical reality with precision. Our customers span industries from automotive and aerospace to defense, industrial, semiconductors, and energy — ranging from hyper-growth startups to Fortune 100 enterprises. Luminary is a Series B company headquartered in San Mateo, California.

As the Senior/Principal Lead Delivery Engineer for Industrial, you own customer outcomes for Luminary's engagements with heavy machinery, industrial equipment, HVAC, pumps, turbomachinery, and engineered products companies. You are a dual hat — project manager and product manager — leading a matrixed value delivery team that converts customer engineering challenges into Physics AI solutions across structural, thermal, electromagnetic, and multi-physics workloads. You partner with the GTM team on account engagement and growth.

• →Own end-to-end customer outcomes across new and existing industrial accounts — from discovery and use case scoping through model development, deployment, and embedding into customer engineering workflows.
• →Author Statements of Work (SOWs), educate customers on the engagement plan, and own delivery accountability against them.
• →Lead a value delivery team in a matrix structure: Applications Engineers, Applied AI/ML Scientists, Data and Platform Engineers, and selected product engineers. Set technical direction, sequence the work, remove blockers.
• →Operate as a dual hat — project manager and product manager — running sprints, milestones, and risk while also choosing the right use cases and shaping the product intuition for what to build next.
• →Stay hands-on-keyboard where it matters. Debug a model, restructure a data pipeline, prototype a workflow integration. Lead from the front, not from slides.
• →Embrace co-engineering: work side-by-side with industrial engineers on use case development, sharing knowledge and building trust through visible, collaborative work.
• →Partner with the GTM tream on new account engagement, GTM-to-delivery handoff, and account growth.
• →Bring market and customer signal back to Product and Research, directly shaping Luminary's roadmap for industrial use cases.

• 5–10 years of experience in a technical role in a relevant industry (engineering, simulation, R&D, advanced engineering, technical program management, or applied AI/ML). Principal-level candidates have an extensive track record in the industry.
• Multi-physics fluency across industrial engineering disciplines: structural mechanics, thermal analysis, electromagnetics, rotating machinery, fluid dynamics, or multi-physics optimization. Generalist depth across several disciplines is more valuable than world-class depth in one.
• Strong hands-on engineering chops — Python, scripting, simulation tools, and AI/ML workflows. Comfortable diving into code, models, or simulation setups when needed.
• Working knowledge of AI/ML applied to engineering — surrogate modeling, neural operators, physics-informed ML, or digital twins.
• Demonstrated ability to lead cross-functional technical teams without direct authority. You influence through clarity, credibility, and outcomes.
• Product instinct: a track record of choosing the right problems to solve and shipping things that get used — not just demos that get cited.
• Customer-facing presence: equally credible explaining a physics model to a chief engineer and walking a customer roadmap with Luminary leadership.
• Self-starter mentality, comfortable with ambiguity, persistent through iteration. You question what you are asked to do and prioritize what actually moves the needle.
• Willing to travel 10–25% to customer sites.

• Advanced degree (MS or PhD) in Mechanical, Industrial, Manufacturing, Electrical, or Materials Engineering.
• Prior experience at major industrial companies (e.g., Siemens, GE, Carrier, Trane, Grundfos, Flowserve, Caterpillar, Atlas Copco, Cummins) or enterprise software companies serving industrial sectors.
• Experience with engineering challenges specific to rotating machinery, heat exchangers, pumps and compressors, or similar complex engineered products.
• Track record of driving technology adoption in industrial environments with measurable business impact (reduced development time, improved performance, lower prototyping costs).
• Experience deploying ML or simulation tooling into production engineering workflows.
