Job description

About Fundamental

Fundamental is an AI research lab pioneering the future of enterprise decision-making. Our flagship model, NEXUS is the world's most powerful Large Tabular Model (LTM) - purpose-built for the structured records that contain trillions of dollars in business value. With $275m in funding from leading investors and trusted by Fortune 100 companies, Fundamental is giving businesses the Power to Predict.

At Fundamental, you'll work on unprecedented technical challenges in foundation model development and build technology that transforms how the world's largest companies make decisions. This is your opportunity to be part of a category-defining company from the ground-up. Join the team defining the future of enterprise AI.

About the role

Fundamental's story is complex, and how it is told matters. This role owns how that story reaches the market: the voice of our founders on X and LinkedIn, our company channels, and the content strategy behind them. You will turn deep technical work into writing that earns the attention of customers, researchers, investors and the people we want to hire.

This is a content role first. You will help decide what we publish, why and where, from long-form blogs and thought leadership to the posts that carry them. You will write in the voice of our founders, with their sign-off, and build a steady rhythm of content that grows an audience over time. You will also help put our leaders in front of the right podcasts and platforms.

You will work from the US, report to our Head of Marketing, and work closely with Jeremy and Gabriel day to day. If you have a few years in marketing and a real specialism in social, you are plugged into the US tech scene, and you write with confidence and work well independently, you will recognise this role. We are looking for someone who enjoys owning a brief from first idea to published piece, and who wants the variety of a small, fast-moving team at an early-stage company.

Key responsibilities

• Own our content strategy: decide what we publish across blogs and long‑form content, and build an editorial plan tied to product, research and company milestones

• Be the voice of our founders: ghostwrite for Jeremy and Gabriel on X and LinkedIn, capture how they sound and get posts approved quickly

• Run our company channels: own the Fundamental LinkedIn and X accounts, from the content calendar to daily publishing

• Make complex ideas accessible: turn technical research and product news into content that customers and researchers want to read and share

• Build the audience: use the data to grow reach and engagement, and tell us what is working and what is not

• Open doors for our leaders: pitch and prepare our founders for podcasts, panels and other earned opportunities

• Turn one idea into many: repurpose blogs, talks and research into posts, threads and talking points

• Find the stories: partner with marketing, product, research and sales to spot what is worth telling

• Keep things moving: manage briefs, approvals and the content calendar, and handle the routine tasks that keep it all on schedule

• Try new tools: use AI‑assisted writing and workflow tools where they help, with strong human editing and fact‑checking

Nice to have

• Podcast and media outreach experience, including pitching and preparing leaders for appearances

• Familiarity with technical subject matter such as AI, machine learning or enterprise software

• Light design or video skills, such as Canva or short‑form video editing

• Experience measuring content impact beyond reach, such as inbound leads, pipeline influence or press coverage

• Experience at an early‑stage or high‑growth company, or on an in‑house technology team
  

Benefits

• Competitive compensation with salary and equity

• Comprehensive health coverage for you and your dependents, including medical, dental, vision, and 401K

• Paid parental leave for all new parents, inclusive of adoptive and surrogate journeys

• Relocation support for employees moving to join the team in one of our office locations

• A mission‑driven, low‑ego culture that values diversity of thought, ownership, and bias toward action
