About Wordware
  • Wordware (YC S24) ) is a toolkit that enables anyone to build, iterate, and deploy their AI stack easily. Our unique approach is centered around Natural Language Programming. Long term we see ourselves as an AI Operating System (aiOS) that acts as an orchestration layer for LLMs, databases, and tools.
  • Sign up for free using this link: app.wordware.ai
  • Primary Tool for Millions of AI Engineers coming to the market in the next 5 years
  • Our users range from AI Tinkerers (free tier) to small startups (for example – 7 YC clients on Company Plan – 899 USD/month) ending at bigger enterprises (Instacart is a client)
  • ⁠In the last 2 months, we went viral a couple of times:
  • Since our launch (2nd of August) we grew from 10k users on our main product, to over 300k today.
  • Repeat founders (Filip Kozera and Robert Chandler) both with exits
  • They’ve known each other for the last 10 years following their research at Cambridge. They have been building companies in Transformers and AI Ops. They have worked full-time on companies together for the last 3 years.
  • The Wordware team is 9 ppl all based in SF.
  • Product + Community Led Growth

note: we're in hustle mode. we're shipping as fast as we can. this is not the kind of job you can cruise and 9-5. only apply if you want to grind, work late nights, and be part of a generational company. We are an onsite company (SF), expect a big house where the founders live, free food, beers and cool team activities.

So we are here, you are looking for a job at a startup huh?

⁉️ What’s it going to be like ⁉️

In Shackleton's famous words: “People wanted for hazardous journey. Low wages, bitter cold, long hours of complete darkness. Safe return doubtful. Honour and recognition in the event of success.”

  • Why tho?

    Risk + Excitement + Hard Work == Startup. Sure, you could join a big company and make decent money but it's that constant thrill of hope, the addictive energy that makes Robert and I come back to startups over and over again 😵‍💫

    To thrive here, you’ve got to embrace this delulu universe, where the victories give us hope and the failures make us want it even more. Yes, we work late hours and often deal with some bullshit, but you'll be part of something bigger and even more, you will have a direct impact on EVERYTHING.

    If you're ready to roll up your sleeves, identify your own features to build, and find your own problems to solve, then come on in. Grab a beer and a slice of pizza, and dive into creating the future of natural language programming and AI agents. Together, we'll revolutionize the way we work. Green Light. 🟢

So, what is Wordware?

***Wordware** is a prompt-first programming language that can be used by non-developers (AI Engineers). We merge concepts like loops, logic and functions from the world of classical programming with the non-deterministic nature of Language Models. It’s exposed in a web-hosted IDE with features like sharing, forking and API deployment.*

About Wordware

Wordware is an IDE for building AI agents using natural language.

It looks and feels like Notion, but lets you design, test, and deploy AI systems in real time - without writing code.

Our mission is to bring structure and joy to human–AI collaboration.

We’re building a generational company that empowers the next billion knowledge workers to create with AI - not by writing code, but by expressing intent.

We’re backed by Spark Capital, Felicis, and Y Combinator ($30M seed round - the largest in YC history).

We work hard, move fast, and don’t take ourselves too seriously. It’s intense, but it’s also fun - at Wordware, you’ll do the best work of your life alongside people you genuinely like.

tl;dr we're building a magical repository where AI agents can be shared, forked, and instantly run (complete with a possible generative UI) and need someone technical enough to be an IC at the start but with the product vision to make this massive

what we're actually building

we're creating wordware, the all-in-one platform for building AI that actually makes sense. our AI agent repository is the beating heart of this ecosystem - it's where tinkerers share their agents, where builders fork and instantly run each other's work, and where the UI itself might even be generative. imagine browsing a library of AI agents that you can not just see, but immediately interact with, customize, and deploy without diving into code.

think about it: most AI today requires diving into code or dealing with complex configurations. we're building something different - a place where AI agents are first-class objects that can be shared, discovered, and deployed without friction. fork an agent, tweak it with our intuitive interface (maybe even with the help of AI), and instantly have your version running and ready to use. this could fundamentally change how AI gets built and shared.

this isn't just a feature - it's the foundation of our community and a key growth engine.

what you'll actually be doing

  • we're looking for super smart ex-CTOs who will start off spending 70% of their time on IC engineering and 30% on PM, with scope for the role to shift over time. please do not apply if this does not sound like the right mix to you
  • owning this project from literal zero to a thriving community
  • getting your hands dirty with early implementation (yes, we need someone who can contribute, not just direct)
  • designing how forking, contribution tracking, and community recognition actually works for AI flows
  • figuring out what metrics actually matter for this kind of community
  • building a system that feels natural to both hardcore AI engineers and people who just want to plug solutions into their workflow

this might be you if:

  • you've built products from nothing before (bonus if you were a founder)
  • you understand AI agents and multi-agent frameworks deeply enough to have opinions
  • you can code when needed but know when to step back and focus on product
  • you've contributed to or built developer communities
  • you get genuinely excited about creating systems that help people collaborate
  • you understand repository and discovery systems and can reimagine them for an AI-first world
  • you can simplify complex concepts without dumbing them down

this probably isn't you if:

  • you need a perfectly defined role with clear boundaries
  • you're looking for a pure management position right now
  • you think AI is "just hype"
  • you've never shipped something from 0 to 1

why this matters

building AI is too damn hard and too damn messy right now. we're trying to fix that, and this collaborative repository is a key piece. get this right, and you'll help shape how the next generation of AI applications gets built.

perks and other stuff

  • early enough to have massive impact
  • small, technical team that moves fast
  • onsite culture in SF + office is 70m from the beach + wind/kite surfing rack + gym and a sauna 🧖‍♂️ 🏄‍♀️

if you've read this far and it resonates, shoot us a note at sebastian @ wordware.ai . tell us about something you built from zero and why you're excited about creating GitHub for AI.

p.s. building this right is incredibly challenging, but that's exactly what makes it worth doing

Technology
  • Full-stack Typescript, Next.js, React and SST serverless on AWS/Cloudflare
  • Using TipTap as the core of our IDE with Y.js for collaboration
  • PartyKit (Cloudflare Durable Objects) for Y.js websockets and likely for future orchestration of pipelines
  • Open source LLMs hosted by Together AI (we’re a customer story on their website) + Groq + OpenAI/Anthropic/Mistral/Google/Cohere/Perplexity for proprietary LLMs
