Growth Engineer (Founding Team Track)

Doplex Labs↗ is a stealth applied AI lab building tools that give people their attention back. Our first product is Belay↗, which helps coding agents stop repeating the same mistakes. Our second is Rotty↗, a free Chrome extension that hides AI slop, spam, bots and engagement bait on Reddit, X and LinkedIn.

Rotty↗ reads each post the way a person would and folds low-effort content into a single line that says why. It runs on the user's ChatGPT plan, a free API key, or a small model that runs entirely in the browser. An open-source version, Rotty Lite, is available on GitHub under the MIT license.

The role

We're looking for a Growth Engineer to help us get Rotty↗ in front of the people who need it and scale it as they arrive. You'll work directly with the founders, split roughly between building and distribution: shipping improvements, growing our open-source community, and finding the channels where Rotty spreads.

This is a volunteer role to start. If Doplex Labs joins an accelerator such as Y Combinator or a16z speedrun, or raises funding, it can transition to become a paid founding engineer role with equity. We'll be straightforward with you about timelines and progress throughout.

What you'll do

• Grow Rotty's↗ user base: launch on platforms like Hackernews, Reddit, X etc; write posts, threads and demos; find and test new channels
• Build and maintain Rotty Lite, our open-source version: review issues and pull requests, write docs, and make it easy to contribute
• Talk to users: collect feedback, spot what's missing, and turn it into improvements
• Ship features and fixes in the extension, especially support for new sites
• Help prepare accelerator and grant applications with metrics and demos

What we're looking for

• You have built something people use and you are AI-native (side projects count)
• You're active in at least one online community and understand how things spread there
• You write clearly and enjoy explaining technical things simply
• You care about the problem: feeds full of filler, bots and bait
• You can commit 8–15 hours a week and work independently

Nice to have

• Experience with Chrome extensions, LLM APIs or local models (Ollama, WebGPU)
• Open-source maintainer or contributor experience
• An audience on X, LinkedIn, Reddit or a blog
• Prior launches on Product Hunt or Hacker News

What you get

• Real ownership and visible impact on an early product, with your name on the work
• Direct mentorship and decision-making alongside the founders
• Public, attributable open-source contributions
• A clear path to a paid founding engineer role with equity if we join an accelerator or raise funding
• Flexible, remote, async-friendly hours

To fasttrack your application

Show us how you'd get Rotty↗ in front of people. Rotty is in review on the Chrome Web Store, so right now growth means waitlist signups. Pick one or two of these (none are required):

• Bring people to the waitlist. Use your own link, getrotty.vercel.app/?ref=yourname (letters, numbers, dots and dashes), so we can see the signups you drove. Tell us where you shared it and why you chose that channel.
• Make something. A short demo video, a thread, a meme, a blog post or a before/after screenshot of a feed full of slop. Post it, or just send it to us.
• Improve the code. Open a pull request on Rotty Lite (github.com/DoplexLabs/rotty-open-source), such as fixing a site's selectors, adding a site, or improving the prompt.

Include what you did and any results in your application. Quality and volume matter the most: the better your idea and the more audience you reach, the more you stand out.
