Chief of Staff

What we do

Cambrium is the new chemical company, engineering molecules with absolute precision to enable performance that didn't exist before. We built an AI engine that designs scalable molecules we can manufacture into performance chemicals, enabling our customers to create products that outperform.

We are an equal-opportunity employer and value diversity. We consider all applications equally regardless of race, colour, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, or gender identity. We strongly encourage individuals from groups traditionally underrepresented in tech to apply. Please apply even if you don't match the criteria exactly. We believe potential and determination beat experience.

Your role

As Chief of Staff, you will sit at the centre of Cambrium's strategic engine, reporting directly to Mitchell, our CEO, and working closely with our interdisciplinary Leadership team. This is a high-impact, high-ownership role for someone who is structured, intellectually curious, and ready to tackle significant challenges in their day-to-day. You will work across the most consequential workstreams in the company, from fundraising and investor relations to board governance and company-wide rhythm-keeping, giving you a front-row seat to how an ambitious deep tech company is built.

You will take full ownership of critical projects, drive them to completion, and raise the bar on how we operate across our science, engineering, and commercial teams. Your responsibilities will change over time and will always remain somewhat flexible. The same goes for what you can do at Cambrium - if you deliver, we will scope the role around you to make sure you can thrive and take your career in the direction that you want. However, if you are craving a neatly scoped, predictable list of responsibilities, this is not the role for you.

Your responsibilities
