Coinask.ai — a B2C AI SaaS product at the intersection of AI, Crypto, and FinTech.

We're looking for a hands-on Senior Creative Designer who will own Coinask's visual quality and personally produce strong graphic and video content.

We don't need someone who just executes a brief — we need a strong designer with great visual taste and an understanding of how design drives business results. You'll create banners, static creatives, landing pages, social content, and video, quickly test different approaches, and improve them based on results.

About the Role

The core focus of this role is hands-on design production.

You'll work across a range of formats — from ad creatives and social content to Figma mockups, landing pages, and video. It's not just about making things "look nice" — it's about understanding composition, hierarchy, typography, visual storytelling, attention, and conversion.

You'll work closely with the Head of Marketing and Lead Brand & Community Manager, turning marketing and communication tasks into quality visual content.

Your Responsibilities

• Graphic Design: create static creatives, banners, social content, marketing materials, and other visual assets.
• Web & Landing Pages: create Figma mockups and the visual side of marketing landing pages.
• Video & Motion: edit short-form and performance creatives for Reels, TikTok, Shorts, and ad campaigns; work with footage, screen recordings, UGC, captions, graphics, basic motion elements, and format adaptations.
• Creative Development: independently develop visual concepts and propose solutions, rather than just executing ready-made briefs.
• Visual Consistency: maintain a cohesive and recognizable visual style for Coinask across channels and formats.
• Creative Performance: analyze the results of your creatives together with Marketing, understand which approaches work better, and apply those insights to future iterations.
• AI Workflow: use AI tools for research, ideation, generation, and production, speeding up the work without sacrificing quality.
  
   

What We Expect From You

• A strong portfolio with examples of graphic design, digital creatives, and video/motion work.
• Confident with Figma, Photoshop, and other professional design tools; hands-on experience editing and producing short-form video creatives.
• Strong visual taste and an understanding of what makes design high-quality, modern, and professional.
• Able to work fast and independently, adapting one design across different formats and tasks.
• Understand the basics of marketing design and performance creatives: hierarchy, hooks, readability, CTAs, attention, and visual storytelling.
• Willing to look at creative results, draw conclusions, and apply them to the next iteration.
• Able to independently find and propose visual solutions rather than waiting for a detailed brief.
• Experience with AI creative tools, used as part of the production workflow.
• Comfortable working in a fast-paced environment with lots of iteration.
  
   

Nice to Have

• Experience with B2C SaaS, AI, FinTech, or Crypto/Web3.
• Experience with performance marketing / creative testing.
• Motion design and 3D.
• Experience building or evolving a visual identity.
  
   

How We Work

We're an AI-native team.

For us, AI is part of the daily creative workflow. We expect you to use AI to speed up research, ideation, generation, and production — but the final output needs to meet a professional design standard.

We value speed, quality, and the ability to move quickly from idea to finished creative.

Create → Launch → Measure → Learn → Iterate

 

This Role Is for You If You're Looking For

• Lots of hands-on work. You'll be directly producing creatives, not just briefing others.
• Freedom in visual decisions. We expect you to bring your own taste and initiative.
• Impact on results. You'll see the performance of your creatives and use that data for the next iterations.
• The chance to shape the visual direction of a new AI product.
• An AI-native environment and a fast creative workflow without unnecessary bureaucracy.

Coinask.ai — a B2C AI SaaS product at the intersection of AI, Crypto, and FinTech.
 

We're looking for a hands-on Lead SEO & GEO Specialist who will take ownership of Coinask's organic visibility across Google and AI-powered search — from the technical SEO foundation and search intent to GEO, authority building, and results measurement.
 

This isn't a classic SEO copywriter or link-builder role. You'll build the system that makes Coinask easier to find, understand, and get referenced in both traditional and generative search.
 

About the Role

Search is changing: alongside classic Google, AI-powered search and answer engines — ChatGPT, Perplexity, Gemini, and others — are growing fast.

Your job is to build the system:

Technical SEO → Search Intent → Semantic Authority → AI Visibility → Organic Growth
 

You'll work closely with the Head of Marketing, Lead Brand & Community Manager, Product, and Engineering, turning search and audience-behavior data into concrete SEO/GEO initiatives.

 

Your Responsibilities

• SEO & Organic Search Strategy: develop and execute Coinask's SEO strategy — keyword research, search intent, semantic clusters, content opportunities, on-page SEO, and internal linking.
• Technical SEO: own crawlability, indexability, site architecture, Core Web Vitals, canonicalization, robots.txt, sitemap, and Schema.org. Identify issues and write specs for Engineering.
• GEO / AI Search Visibility: track Coinask's presence in ChatGPT, Perplexity, Gemini, Google AI Overviews, and other AI search experiences; find citation gaps, competitor gaps, and opportunities to grow AI visibility.
• SEO Content Strategy: identify content gaps and write SEO/GEO briefs for the Brand & Community team — what to create, for which search intent, and what structure and topics to cover.
• Authority & Digital PR: identify relevant crypto/tech media and authoritative platforms, run outreach, negotiate placements, and see quality mentions and backlinks through to publication.
• Analytics & Measurement: build the SEO/GEO measurement system: organic traffic, rankings, conversions, backlinks, AI visibility, citations, and the organic channel's contribution to acquisition.
• Use AI and automation for research, semantic analysis, competitor research, data processing, monitoring, and scaling SEO processes.
  
   

What We Expect From You

• 3+ years of hands-on experience in Technical SEO / Organic Growth / SEO Management, ideally in B2C SaaS, AI, Crypto, Web3, or FinTech.
• Deep understanding of Technical SEO, semantic SEO, search intent, and authority/link building.
• Confident with Google Search Console, GA4, Ahrefs / Semrush, Screaming Frog, or similar tools.
• Understand the principles of AI Search / GEO / AEO, citation patterns, and how AI systems find and use sources.
• Able to run SEO audits, keyword research, and competitor analysis, and turn findings into concrete actions.
• Hands-on experience in link building / SEO outreach and securing quality editorial placements.
• Technical literacy — comfortable working with HTML, Schema.org, and web architecture, and writing specs for Engineering.
• Strong analytical thinking: able to turn data into SEO hypotheses, priorities, and experiments.
• High autonomy and ownership — able to independently move from opportunity → strategy → execution → measurement.
• Fluent English for working with the Western search landscape, English-language semantics, and international media.
  
   

Nice to Have

• Experience with AI products / AI-native SaaS.
• Experience in Crypto / FinTech / Web3.
• Hands-on experience with GEO/AEO platforms and AI search monitoring.
• Python / SQL or automation via n8n, Make, or similar tools.
• Understanding of YMYL, trust, and compliance in financial and crypto products.
  
   

How We Work

We're an AI-native team.

For us, AI isn't a separate skill on a resume — it's part of the daily workflow. We expect you to use AI and automation to speed up research, technical audits, semantic analysis, monitoring, and data processing, so you can stay focused on strategy and decision-making.

We value speed, autonomy, and the ability to move quickly from idea to test.

Research → Identify → Optimize → Deploy → Measure → Iterate

You'll have the freedom to build the Organic Search function, while also owning its real impact on the business.

 

This Role Is for You If You're Looking For

• The chance to build Organic Search from scratch. You'll have a direct impact on how Coinask is found in Google and AI search.
• A new level of SEO. Combining Technical SEO, semantic search, and GEO in one product.
• Real impact on the product. Your search insights will shape site structure, landing pages, content strategy, and GTM.
• Hands-on ownership. You don't just make recommendations — you find opportunities, launch initiatives, and measure results yourself.
• An AI-native environment. AI and automation are part of the workflow, not a side experiment.
• High speed and autonomy. Minimal bureaucracy and a short cycle from insight to implementation.

• Marketing Analytics & Attribution: connect ad spend, traffic sources, sign-ups, and product events so Marketing and Product see accurate CAC, ROAS, conversion, and LTV.
• Data Quality & QA: regularly audit data, find duplicates, data loss, broken events, and discrepancies between systems; identify root causes and coordinate fixes with Engineering.
• Dashboards & Reporting: build and maintain clear dashboards for Marketing, Product, and Management, keeping metrics up to date with a single shared definition.
• Insights: find anomalies, patterns, and growth opportunities in the data and turn them into actionable insights for Product and Marketing.
• Use AI and automation tools to speed up analysis, SQL, QA, debugging, and data work.
  
   

What We Expect From You

• 3+ years of experience in Product Analytics, Web Analytics, Marketing Analytics, Analytics Engineering, or Tracking.
• Confident with GTM, GA4, and product analytics tools — Amplitude, Mixpanel, PostHog, or similar.
• Understand how events, cookies, first-party data, server-side tracking, APIs, and Webhooks work.
• Strong SQL skills and the ability to work independently with data in PostgreSQL, BigQuery, or similar systems.
• Hands-on experience building integrations and data flows between marketing, product, and backend systems.
• Understand marketing attribution principles and how to connect acquisition data with product metrics.
• Able to build dashboards and reporting systems that teams actually use.
• Able to independently identify the root cause of data discrepancies and drive them to resolution with Engineering.
• Strong analytical and business thinking: you understand not just how to get a number, but why the business needs it.
• High autonomy, ownership, and comfort working in a fast-paced environment.
  
   

Nice to Have

• Experience with B2C SaaS / subscription products.
• Python or JavaScript for custom scripts and API work.

We're an AI-native team. AI is part of our daily workflow. We expect you to use AI for writing SQL, analyzing data, debugging tracking, automating QA, and speeding up routine tasks.

We value speed, pragmatism, and autonomy: a reliable system that works today beats a complex architecture that will be ready in six months.

Track → Connect → Validate → Analyze → Improve

This Role Is for You If You're Looking For

• Real business impact: your data and insights will be used directly by Marketing and Product.
