Unusual helps brands understand how LLMs talk about them, and gives them tools to change their minds.
This is an immensely important and interesting technical challenge – our engineering team focuses on reverse engineering the sources, implicit biases, and reasoning patterns that guide model behavior, and builds products that use this understanding to help people regain control over how they are represented.
From a product perspective, we have a unique opportunity to define the new field of ”Brand Engineering”: we can accurately measure LLM’s opinions of a brand, which enables us to quantify a brand’s performance relative to their peers along any dimension. By putting numbers to these previous intangibles, we can add an element of science to the art of brand; perhaps the final piece of a decades-long effort to bring math to marketing.
If you want to define a product category, push the boundary on a new field of research – applied interpretability, and make a positive impact by helping people control their own narrative rather than large AI companies, we’d love to talk.
As a Founding Engineer, you’ll own problems end-to-end – from high level customer insight all the way to research and infrastructure. You’ll keep a close feedback loop with customers and the executive team, and ship fast.
In addition, you’ll help shape a new engineering team at the dawn of a new kind of software development. Vibecoding is the next paradigm, and as AI tooling improves, we’ll need to work together to regularly reinvent the best patterns and practices for working alongside agents on a team.
You are a high-agency builder who thrives on difficult technical problems and wants to own outcomes end-to-end, from customer insight to shipped feature.
We're backed by Y Combinator and the first investors in SpaceX, Uber, Stripe, Clay, and Notion. And our team has solved some of the most challenging problems in technology and go-to-market—ranging from building the first Starlink prototype at SpaceX to scaling startups into market leaders within the most competitive industries.
Our values
Our cofounder and CEO Will Jack is a second-time founder who previously started Khosla-and-Greylock-backed Remedy Health. Will has been working in NLP research since 2014 (using attention mechanisms before the Transformer) and is ex-SpaceX, MIT. He was the first person to commercialize AI code generation in 2019 while working on HBO’s Silicon Valley. He gained international recognition as a teenager for building a homemade nuclear fusion reactor. Github:
Our cofounder Keller Maloney has been building in AI applications since 2019, and he was Cum Laude in Econometrics from Princeton University and was a D1 All-American water polo Captain. Github:
Our Head of GTM, Sarah Xu, is a repeat GTM builder with deep empathy for Heads of Growth and agencies. She drove 10X growth at Circle Medical (YC W17), built Ambience Healthcare’s GTM from pre-revenue (led to $350M raised by Oak HC/FT, Kleiner Perkins, OAI, a16z), and designed growth engines at Google for companies and agencies that scaled revenue 5–10X.
Unusual helps brands understand how LLMs talk about them and provides tools to change those representations. It defines and aims to lead Brand Engineering, a field that measures LLMs' opinions of a brand and quantifies brand performance relative to peers. Its mission includes helping people control their own narrative rather than large AI companies. The company is led by cofounders Will Jack, CEO, and Keller Maloney, with Sarah Xu as Head of GTM, and the team includes alumni from MIT, Princeton, and SpaceX. Will Jack has been involved in NLP research since 2014 with experience at SpaceX and MIT and was the first to commercialize AI code generation in 2019 on HBO’s Silicon Valley, while Keller Maloney has built AI applications since 2019, graduating cum laude in Econometrics from Princeton and serving as a D1 All-American water polo captain. Sarah Xu has driven 10x growth at Circle Medical (YC W17) and built Ambience Healthcare’s GTM from pre-revenue, contributing to about $350M raised by Oak HC/FT, Kleiner Perkins, OAI, and a16z, and has designed growth engines at Google that scaled revenue 5–10x.

No applications, no recruiter spam. Just the intro.
A few questions to make sure this role is the right shape for you. Two minutes.
I write the intro, send it to the founder, and handle the back-and-forth.
If they’re a yes, I book the chat. You show up — that’s the whole job-hunt.
