Chief Information Security Officer (CISO)

Yesterday San Francisco, CA
About Lumafield: 

Lumafield was founded in 2019 to upgrade manufacturing.

We are engineers with deep experience across the product development cycle, from initial ideas to shipping hardware, across industries and specializations, who became frustrated by the cost and complexity of modern manufacturing. So we decided to upgrade it.

Engineers make million-dollar decisions every day, and they need tools that give them the greatest possible insight into their products. By offering unprecedented visibility into products, as well as AI-driven tools that highlight problems and generate quantitative data, Lumafield promises to revolutionize the way complex products are created, manufactured, and used across industries. We started with industrial CT scanning, which for us was the most valuable but underutilized tool in the manufacturing toolbox, enabling us to rapidly inspect essential components non-destructively.

We rebuilt the whole system, from X-ray capture, to computer vision analysis, to web-based collaboration, to the entire business model, making the most advanced manufacturing tech more accessible to every industry. Our company, like our platform, is designed for upgrades. We’re building for greater intelligence, autonomy, and speed. For deeper vision, operational excellence, and powerful insights. And then we'll upgrade it all again.

Lumafield is headquartered in Cambridge, MA, and has an office in San Francisco, CA.

About the role: 

As CISO, you will own Lumafield's security function end-to-end—from cloud infrastructure and product security to customer data protection and regulatory compliance. This is a rare opportunity to define security culture and architecture at a high-growth company whose customers share some of the most sensitive intellectual property in the world: proprietary product designs, internal manufacturing processes, and competitive R&D data.

You will report directly to the CEO, and partner closely with Engineering, Product, Operations, and Sales to make sure security enables the business rather than slows it down.

  • Be an integral part of our enterprise sales process — handle security questionnaires, support complex sales cycles, and build trust with InfoSec teams at major manufacturers

  •  Build and continuously test Lumafield's incident response plan; own the enterprise risk register and manage third-party vendor risk

  • Champion a security-first culture through training, clear policies, and acting as a pragmatic advisor to business stakeholders

  • Experience managing security in enterprise sales cycles, including responding to customer security questionnaires and participating in procurement reviews
