Jobs at Djinni

Snoika is an AI marketing engine that helps companies get seen in AI search (ChatGPT, Perplexity, Gemini, etc.).

We create high-quality, long-form articles for customers in different verticals:

• B2B SaaS
• B2B services
• B2C products

We’re now looking for a Content Editor who loves polishing great drafts into publish-ready content and is comfortable talking to customers.

What you’ll actually do

This role is full-time and very hands-on. Your day-to-day will look like this:

1. Review & edit AI-generated articles
   • You work with very high-quality AI drafts that are already “humanized” by Snoika’s algorithms.
   • Your job is to edit, not rewrite from scratch: improve clarity, flow, structure, tone, and correctness.
2. Fine-tune content for real businesses
   • Our customers are founders, marketers, and teams in B2B SaaS, B2B services, and B2C products.
   • You make sure every article feels useful, specific, and non-generic for that audience.
3. Communicate with customers
   • Send the article for review, handle comments, and clarify expectations.
   • Sometimes you’ll explain editorial decisions or propose better angles.
4. Implement feedback & publish
   • Apply client feedback without breaking quality or structure.
   • Prepare the article in Snoika’s CMS:
     • Review formatting & headlines
     • Add images if needed
     • Check internal & external links
     • Click “publish” and do a quick post-publish sanity check

What we’re looking for

You’ll be a great fit if:

• You have strong editing skills and can spot fluff, repetition, and weak structure quickly.
• You can keep the author’s voice while making the content sharper and more professional.
• You’re comfortable working with AI-generated text (and not scared of it).
• You understand basics of SEO (headlines, keywords, internal links, search intent).
• You can communicate clearly and politely with customers in English (both written and spoken).
• You’re reliable: if you set a deadline, you hit it.

Nice-to-haves (not mandatory, but helpful):

• Experience with B2B SaaS or technical content
• Experience in an agency or content/SEO team
• Familiarity with CMS tools (WordPress, Webflow, custom CMS, etc.)

How we work

• Fully remote, async-friendly
• Direct communication with the founder and core team
• Fast, experimental environment: we ship, test, improve

What we offer

• Competitive salary and opportunity for career growth.
• Senior peers & advisors - work alongside PhDs who've worked with NASA, Google, Microsoft, Bosch and more.
• Fast growth - startup scaling revenue and product lines quarter-over-quarter.
• Remote autonomy & flexible hours - we care about output, not chair time.

If you're excited to push the boundaries of AI Search Engine Visibility and Optimization, and want to help shape the future of marketing technology, we want to hear from you!
