Applied AI Engineer - Internal

Matter Intelligence • San Francisco, CA

51d • Onsite

About The Position

Matter Intelligence is building the future of vision AI: pairing a world-first sensor that sees molecular chemistry, temperature, and 3D shape with a Large World Model—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, co-founded and led infrastructure for OpenAI, designed cutting-edge sensors for U.S. Defense, and invented core algorithms for spectral and 3D imaging. We've come together to build the next infrastructure for vision and intelligence in the physical world.
Matter is building technology at the intersection of hardware, AI, and Earth observation. This role sits at the boundary of Engineering and Operations.
As the first hire in this role, you'll work directly with teams across Matter: sensor engineers, ML researchers, satellite systems designers, sales, and leadership. Your job is to understand how they work, identify where intelligent agents can compress hours into seconds, and build them. You might spend a week designing a multi-agent workflow to automate competitive intelligence tracking, then shift to an internal tool that gives the hardware team instant retrieval across five documentation systems. You own problems end-to-end - from discovery through deployment through iteration.
This isn't a role for someone who wants to follow a ticket queue. It's for a developer with strong CS fundamentals who can operate with autonomy, earn trust across a demanding organization, and ship production-grade agents that people actually depend on.

Requirements

• B.S. in Computer Science or equivalent practical experience.
• Demonstrated ability to build and ship production software: clean code, version control, testing, CI/CD.
• Hands-on experience building with LLM APIs and/or agent frameworks — you've built something real, not just followed a tutorial.
• Strong product instincts: you can sit with a stakeholder, understand their workflow, identify what actually matters, and scope something achievable.
• Security-conscious by default: you think about access control, data handling, and failure modes before they become problems.
• Clear written and verbal communicator — you can write documentation a non-engineer will actually read.

Nice To Haves

• Experience building internal tools or automation for operational teams (BizOps, RevOps, FinanceOps, etc.).
• Familiarity with agentic design patterns: tool use, memory, multi-agent coordination, human-in-the-loop flows.
• Experience with agent evaluation and observability tooling (LangSmith, Langfuse, Braintrust, or similar).
• Comfort with RAG architectures and vector database selection.
• Prior experience in a startup environment where you had to own end-to-end delivery without heavy infrastructure.

Responsibilities

• Design, build, test, and maintain production-grade AI agents and tools using current frameworks and APIs.
• Architect agentic systems that are reliable, secure, observable, and maintainable.
• Build AI-native UX patterns that reduce friction to adoption: human-in-the-loop checkpoints, auditability, graceful failure/rollback, and feedback mechanisms.
• Select and integrate appropriate tools, memory systems, and retrieval strategies for each agent's use case.
• Write clean, well-documented, version-controlled code. You set the standard.
• Interview stakeholders across engineering, hardware, science, sales, and leadership to identify high-leverage opportunities for automation and value creation.
• Run user interviews, workflow audits, and surveys to understand actual bottlenecks before writing a line of code.
• Translate qualitative findings into clear, scoped requirements and build plans.
• Maintain a prioritized backlog of agent opportunities with transparent reasoning on what gets built next and why.
• Work across every part of Matter; no two weeks will look the same. One week you're building a pipeline tool for the payload team; the next you're automating how sales tracks relationships.
• Be responsive, communicate clearly, and follow through - your coworkers are your clients.
• Own rollout and change management for what you build: onboarding, adoption, feedback loops, and iteration based on real usage.
• Share and document best practices for working with AI tools across the organization. Lead training session on the best practices for AI adoption and use.
• Build with security first: apply proper secret management, access control, and prompt injection defenses from day one.
• Write agent documentation that humans can actually use—runbooks, decision logs, API specs.
• Establish evaluation frameworks and monitoring so stakeholders know when an agent is working and when it isn't.
• Own quality end-to-end: you ship it, you support it, you improve it.

Benefits

• Competitive total package based on experience.
• Early-stage equity package so you share directly in Matter's growth and success.
• 100% employer-paid health, dental, and vision coverage.
• Unique exposure across hardware, software, science, and commercial teams—and a front-row seat to building the world's most capable sensing and intelligence platform.
