Applied AI Engineer (Product)

About Matter Intelligence

Welcome to Matter, where we are building the future of vision AI: pairing a world-first sensor that sees molecular chemistry, temperature, and 3D shape with a Large World Model that will be the most powerful intelligence engine for the physical world. This system doesn't just see what something looks like; it understands everything from a single pixel. We call this Superintelligent Vision.

Our team has delivered technologies to Mars for NASA/JPL, designed advanced sensors for U.S. Defense, and built core infrastructure at OpenAI. We are now building the next generation of space- and airborne-based sensing systems.

About The Role

Matter is hiring a Product Intelligence Engineer to turn physics-informed models, general-purpose AI, and ultraspectral data into secure, evidence-backed intelligence products. Reporting to Ignacio Cases Martin, this hands-on individual contributor will build agentic workflows, retrieval and tool integrations, reports, and human-in-the-loop experiences that help customers make operational decisions.

Key Responsibilities

• Build production workflows that combine physics-informed models, LLMs, VLMs, world models, scientific code, data services, and deterministic rules through stable interfaces.
• Design durable execution across state, planning, model routing, retrieval, memory, tool use, retries, timeouts, checkpoints, human approval, and recovery.
• Create evidence-backed outputs that distinguish source data, model inference, system-generated synthesis, user input, and unresolved uncertainty.
• Partner with product and design to build workflows for review, correction, comparison, approval, reporting, and recovery.
• Build context, retrieval, memory, and indexing patterns that respect permissions, freshness, versioning, retention, and evidence lineage.
• Evaluate real system behavior across task success, groundedness, scientific validity, safety, latency, cost, and human intervention.

Qualifications

Required

• Experience building production AI applications, agent systems, workflow engines, backend services, or complex software products.
• Strong hands-on engineering skills across APIs, stateful services, databases, asynchronous execution, testing, debugging, and production operation.
• Practical experience with LLMs or multimodal systems, retrieval, memory, tool use, model routing, structured generation, and common failure modes.
• Product judgment and the ability to connect technical design choices to the user decision or workflow being improved.
• Experience building systems with security, permissions, data isolation, auditability, or human-approval requirements.

Preferred

• Experience with scientific, geospatial, industrial, defense, autonomy, or other high-consequence intelligence systems.
• Experience building multimodal applications that combine imagery, maps, time series, documents, structured data, or sensor streams.
• Experience with agent evaluation, constrained generation, program synthesis, durable workflow systems, or mixed cloud and edge architectures.
• Experience working closely with product and design teams to ship customer-facing capabilities.

What Success Looks Like

• Customers receive timely, evidence-backed answers and workflows that support real operational decisions.
• Agentic capabilities behave predictably across failures, version changes, unavailable dependencies, and human-review boundaries.
• Reusable product-intelligence components reduce one-off integration work without obscuring user control or scientific evidence.

Location

This role is based in San Francisco, CA, and requires onsite work.
