About Us

Fact Machine is reinventing how people engage with opinions online. We run 24-hour prediction markets on subjective questions - think "Should the US acquire Greenland?" or "Is this the right take?"- where users trade on predicted consensus outcomes. We've raised $8.2M and are preparing for public launch in the next 3 months after a successful closed alpha.

The Role

We’re looking for a Senior Full-Stack Engineer to join our core team. You’ll be working closely with our CTO and three more engineers to bring the product to life across the stack.

This is a foundational role based on ownership, speed, and autonomy - ideal for someone who has deep experience working at early stage startups, familiarity with our typescript stack (NestJS + NextJS) and wants to build something truly new that we know can scale massively.

What You’ll Do

• Contribute to our frontend built with Next - from wallet integrations, transaction flows to real-time market UIs and fluid animations.

• Develop, deploy, optimize our backend codebase (a mix of Rust + a NestJS), including transaction relayers, Rest APIs, real time updates, or on-chain indexing

• You may configure and manage infra, build and maintain CI/CD workflows, or dive deep on application security and system health, among others.

• Beyond all, optimize for speed, reliability, and UX. We’re heavily indexed on ease-of-use - anything we build must appeal to everyday users beyond the crypto native crowd. 

• Ship rapidly: prototype, test, and deploy iteratively as we expand and scale.

You Might Be a Fit If You

• Are comfortable with a high degree of ownership + responsibility in a high trust environment. We operate in a flat hierarchy and we’re lean. You will not be micromanaged, all we care about is output.

• Have prior on-the-job experience working in full stack development that’s experienced heavy usage or supported a large user base. Extensive crypto development experience is a great addition to this (but not required).

• Are comfortable building across the stack: TypeScript/React (frontend), and TS/Nest (backend/APIs). Some react experience is a must for this role. 

• You already understand how to build and scale high frequency consumer applications and have worked closely with product and design teams to bring ideas to life.

• If you don’t know something, your first instinct is not to give up or delegate, it’s to learn it.

• You’re proactive. You see problems and want to fix them without being told to. 

• Are based in New York City and willing to work in person - this role is embedded closely with our CTO and founding team who all work in-person in NYC.

Why Join Us

• Work side-by-side with experienced builders at the very beginning of a new category of application.

• Build something original.

• This is an incredibly high impact role.

• As we scale we will scale you with us - you’ll eventually lead teams, play a key role in managing the technical infrastructure, and help set requirements and goals as the team grows. 

• Competitive compensation, meaningful equity, and a tight feedback loop from real users.
