Global Growth Marketer / Digital Marketer for IrukaDark at CORe / IrukaDark
About IrukaDark: https://irukadark.com/
IrukaDark is a desktop AI assistant built for the small but constant tasks that slow down daily PC work.
With a simple shortcut, users can instantly summarize, translate, rewrite, proofread, understand copied text, organize notes, and process information without breaking their workflow.
Unlike long-running autonomous AI agents, IrukaDark is designed as a “Super-Sub AI”: fast, lightweight, always close to the user, and focused on helping people think, read, write, and work faster in the moment.
We are now expanding IrukaDark globally and are looking for a hands-on digital marketer who can help us grow the product organically across global markets.
About the Role
We are looking for a global growth marketer who can help IrukaDark acquire users through organic, creative, and unconventional marketing.
This is not a role focused on paid advertising. We already have in-house expertise for web ad operations, so we are looking for someone who is strong in early-stage growth, community-driven marketing, viral campaigns, social media, launch strategy, Product Hunt, Reddit, founder-led marketing, and other organic channels.
This is an early-stage role. You will work closely with the founding team and have a direct impact on how IrukaDark is positioned, launched, discussed, and adopted by users around the world.
This role is ideal for someone who enjoys messy early-stage growth, understands internet culture, can create momentum from scratch, and knows how to turn a useful product into something people want to share.
This is intended for people who have experience using IrukaDark as a user. Without the user’s perspective, it is difficult to communicate the real value of a product designed around speed, workflow, and daily productivity.
Responsibilities
・Plan and execute global organic growth strategies for IrukaDark
・Drive user acquisition through social media, communities, creator outreach, Product Hunt, Reddit, Hacker News, X, LinkedIn, Discord, Slack communities, and other relevant channels
・Create and test viral marketing campaigns, launch campaigns, and unconventional growth ideas
・Lead Product Hunt launch strategy, preparation, positioning, community activation, and follow-up
・Identify communities where IrukaDark can naturally spread among developers, AI users, productivity enthusiasts, creators, marketers, founders, and knowledge workers
・Create content ideas that clearly communicate IrukaDark’s value as a fast, lightweight “Super-Sub AI” for daily PC work
・Turn product features into strong narratives, hooks, posts, demos, and campaign concepts
・Work with the team to create landing page copy, launch messaging, social posts, newsletters, and community posts
・Collect user feedback from communities and turn it into product and messaging insights
・Experiment with scrappy growth tactics that are practical, fast, and measurable
・Build repeatable organic growth loops for global user acquisition
・Help define IrukaDark’s global positioning, category, tone, and communication strategy
Requirements
・Experience growing digital products through organic channels
・Experience with social media marketing, community marketing, or growth marketing
・Strong understanding of global internet culture, startup culture, AI tools, and productivity software
・Experience using platforms such as Product Hunt, Reddit, X, LinkedIn, Discord, Hacker News, or niche online communities
・Ability to create compelling hooks, posts, campaigns, and product narratives
・Ability to move quickly, test ideas, learn from results, and improve continuously
・Strong communication skills in English
・Comfortable working remotely and independently
・High ownership and a willingness to do hands-on, unglamorous growth work
・Interest in AI tools, productivity products, desktop software, and new user experiences
Nice to Have
・Experience launching products on Product Hunt or similar platforms
・Experience growing a product globally from an early stage
・Experience with founder-led marketing or startup growth
・Experience creating viral posts, short-form videos, memes, demos, or community-driven campaigns
・Experience with SEO, content marketing, newsletters, or organic acquisition funnels
・Experience marketing AI products, productivity tools, developer tools, browser extensions, desktop apps, or SaaS products
・Experience working with creators, influencers, affiliates, ambassadors, or community partners
・Experience analyzing organic growth metrics and improving acquisition loops
・Experience with copywriting for landing pages, launch pages, app stores, or product announcements
・Ability to understand the product deeply and explain it in a simple, sharp, and memorable way
What We Do Not Prioritize
This role is not mainly focused on paid advertising, media buying, or web ad operations.
Experience with Google Ads, Meta Ads, TikTok Ads, or other ad platforms is welcome, but it is not the core requirement for this position.
We care much more about your ability to create organic momentum, find distribution opportunities, understand communities, build trust, and make people talk about IrukaDark.
Ideal Candidate
You may be a strong fit if you:
・Have helped a product grow without relying mainly on paid ads
・Understand how to make people notice, try, and share a product
・Know how to create traction in online communities without sounding spammy
・Can write posts that feel native to each platform
・Can think like a user, marketer, and product person at the same time
・Enjoy experimenting with unusual, scrappy, and creative growth tactics
・Are comfortable with ambiguity and can create opportunities from scratch
・Believe that great marketing is not only about promotion, but also about finding the right message, the right audience, and the right moment
