Freelance Math Content Developer Jobs in Austin, TX

We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built – but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

We're singularly focused on delivering 10 to 100s of GW of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them – with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization‑scale infrastructure for AI.

Fluidstack operates at the center of one of the most consequential buildouts in computing history. We are building datacenters and deploying supercomputers faster than anyone else in the world, for customers who are building the future of AI. We are looking for the person who will build the brand, voice, and community presence of Fluidstack from the ground up. You will make a deeply technical company legible, interesting, and compelling to builders, engineers, operators, investors, and executives who are making the most important infrastructure decisions of the decade.

• Own the Fluidstack brand narrative end‑to‑end: messaging architecture, positioning, tone, and how we talk about the company across every surface.
• Build and run a content engine that produces technical writing, long‑form analysis, customer stories, and product deep‑dives that are actually worth reading. Write, edit, commission, and publish on a consistent cadence.
• Ghost‑write for Fluidstack founders and executives: op‑eds, X and LinkedIn threads, conference keynotes, investor communications, and in‑person remarks. You are the voice behind the voice.
• Own Fluidstack's social presence across X, LinkedIn, and wherever the relevant technical audience actually spends time. Build an editorial calendar, write posts, and grow an audience measured in influence, not just impressions.
• Plan and execute Fluidstack's presence at the conferences and events that matter: Supercomputing, GTC, Hot Chips, and AI infrastructure gatherings. This includes field marketing, hosted dinners, side events, and anything that puts the right people in a room together.
• Maintain strong relationships with technical media, independent researchers, and infrastructure voices who shape opinions in this space. Know what they care about and give them something worth writing about.
• Partner with Sales, Product, and Engineering to translate what we are building into narratives and content that resonate with technical buyers and decision‑makers.
• Track what is working. Use coverage, reach, and engagement data to sharpen strategy and cut what is not driving impact.

• Top 1% writing ability. You write with clarity, precision, and voice. You can write a 2,000‑word technical explainer and a three‑sentence X post with the same level of care, and both are good.
• Proven track record of building a technical brand or community presence from the ground up. You have made something interesting that was not interesting before.
• Deep fluency in the AI infrastructure, compute, or developer tooling space. You understand what a GPU cluster is, why InfiniBand matters, what SLURM does, and what keeps ML engineers up at night. You do not need to be an engineer, but you need to be able to talk with them credibly.
• Experience ghostwriting for executives or founders in a technical or enterprise context.
• Experience planning and executing events or field marketing programs in a technical community.
• At least 6 years of relevant experience in brand, content, developer marketing, developer relations, or technical marketing at a company where the product is genuinely complex.

• Experience at an AI infrastructure company, neocloud, GPU OEM, or developer‑focused infrastructure platform (CoreWeave, Lambda, Together AI, Cloudflare, HashiCorp, Oxide, Tailscale, or similar).
• An existing audience or reputation in the AI/ML or compute infrastructure community.
• Experience running a developer relations or developer community program in addition to brand and content responsibilities.
• A portfolio that includes at least one piece of technical writing you are genuinely proud of. Bring it to the first conversation.
• Experience building and managing a small team or network of freelancers to scale content production without losing quality.

The base salary range for this position is $200,000 – $400,000 per year, depending on experience, skills, qualifications, and location. Total compensation may also include equity in the form of stock options. We are committed to pay equity and transparency.

Additional benefits include a retirement or pension plan in line with local norms, health, dental, and vision insurance, and a generous PTO policy in line with local norms.
