Jobs at Djinni

Hi, we are a fast-moving product team launching a next-gen AI Harness product (business, marketing, education). We have already stabilized unit economics at $100k/mo. Now, we are ready to scale to $1M+/mo.

A $100k foundation is just a starting signal. We aren't looking for a passive optimizer to maintain a running machine. We need a builder who can pressure-test what exists, tear it down, and rebuild the engine from scratch if the current setup breaks at scale.

The Reality Check:
You report directly to the CEO. Flat structure, zero bureaucracy, and a budget that scales as fast as you can prove ROAS. It's not a dashboard-watching role. You personally run the global Google Ads engine from initial validation to deep optimization. You won't have a 50-person engineering team or a ready-made playbook.

If you want total freedom to scale an acquisition engine from $100k to $1M+ a month - this is your playground. If you need a fully stable corporate environment to feel comfortable, it's not your perfect role.

Your Mission

• Own the Engine: audit, validate, and rebuild the Google Ads strategy (search-first, global markets) from scratch.
• Aggressive Scaling: push the current $100k/mo foundation to a profitable $1M+/mo, tearing down any setups that break.
• CEO Collaboration: work directly with the CEO on budget forecasting, growth planning, and P&L strategy.
• Data-Driven Growth: deep-dive into funnel data to optimize the entire user journey from impression to conversion.

What Makes You the Perfect Fit

• Proven Scalable Track Record: a real case of building a Google Ads channel across global markets from a blank account to significant profitable spend (up to $1M and more).
• Absolute Hands-on Mastery: direct practitioner who knows search inside out and knows how to hit CPA/ROAS targets.
• Product Mindset: fluency in SaaS and mobile metrics (LTV, CAC, retention, churn, payback period).
• Technical Independence: expert setup of Google Ads, GTM, and tracking architectures (GA4, AppsFlyer, or Adjust) from scratch.
• High Agency: thrives in ambiguity, acts without waiting for instructions, and pivots fast based on hard data.
• Language: Upper-Intermediate (B2+) English or higher.

What's in It for You

• Total Freedom: zero micromanagement with absolute control over strategy, execution, and budgets.
• Uncapped Budgets: access to unlimited marketing budget as fast as you can prove profitable ROAS.
• Zero Bureaucracy: test and launch new ideas in hours, not weeks.
• AI Domain: hyper-growth product in the world's fastest-growing tech sector.

Perks & Benefits

• Remote-First & Coworking Coverage: work from anywhere globally, with your coworking space membership covered.
• Time Off to Recharge: 20 working days of fully paid vacation per year, plus paid sick leave.
• Learning & Growth: compensation for professional courses, conferences, specialized workshops, and intensive English training.
• Healthcare: comprehensive medical insurance, and access to corporate doctor.

• Prepare and analyze reporting on turnover, balances, and financial performance for management
• Coordinate correspondence with banks on operational matters, including refunds, chargebacks, and account-related issues
• Continuously improve and automate treasury-related processes in collaboration with Financial Control and other internal teams
• Participate in the transition to a new ERP system, adapting treasury data structures and workflows accordingly
• Support ad hoc projects and reporting as assigned by senior management

• Experience opening and closing bank/EMI accounts across multiple jurisdictions
• Solid understanding of KYC procedures and regulatory compliance requirements
• Strong analytical skills and confidence negotiating directly with banks on fees and terms
• Upper-Intermediate English proficiency, both oral and written

We are looking for a Creative Marketing Lead to become the very first creative lead on our web-based social networking product and build the function from the ground up: processes, testing methodology, and a team of your own. This isn't about crafting a 3-second Gen-Z hook for TikTok,it's about earning emotional trust with a mature audience on Tier-1 markets with an exceptionally long customer lifetime, a fundamentally different creative challenge than most of the market faces. Our web2web, credit-based monetization model runs on different funnels, different logic, and different insights than the mobile-subscription products most competitors build, and your work will plug directly into a UA team already managing $300K+ per month with a clear path to $1M+, so every hypothesis gets tested against real volume, fast. You'll make decisions without red tape, own the creative direction end-to-end, and build a team of 6 creative marketers and designers over the next 3–6 months in a place where 70% of our heads and leads have grown from within

About our product: We have created an international web platform that's genuinely changing how people connect in Tier-1 markets: 1 million users across the USA, Canada, and UK trust us for meaningful relationships that go beyond surface-level matching! Since 2020, we have been the platform for people seeking real connections. Our users enjoy 24/7 communication, seamless content sharing, and a completely ad-free experience. We have found our sweet spot in performance and intuitive design that keeps people engaged and actually connecting with each other. So, you will be part of an ambitious journey toward our clear goal: becoming one of the Top-5 international social networking platforms globally. We are already succeeding in our current markets, and now we are ready to bring that same thoughtful approach to worldwide scale.

In this role, you will

• Own the end-to-end creative strategy across paid channels, starting with Meta and expanding into Snapchat, TikTok, and Google, in close partnership with the UA team
• Run the full creative cycle: research, insight, hypothesis, brief, production, launch, analysis, and iteration
• Generate original creative concepts, narratives, angles, and messaging tailored to different audience segments, not just hooks
• Build and evolve a creative testing methodology, from hypothesis design to clean test execution and pattern recognition
• Hire, lead, and grow a team of 6 creative marketers and designers, setting quality standards and giving hands-on feedback
• Track competitors and trends through Meta Ad Library, TikTok Creative Center, and Google Ads Transparency Center, turning observations into prioritized creative bets
• Embed AI tools into the creative production pipeline to increase testing speed and volume

It's all about you

• 3+ years in creative marketing, performance creative, or creative strategy, including 1+ year leading or mentoring a creative team
• Strong performance background and a direct-response mindset – you know why a creative works, not just that it does
• Hands-on experience scaling creatives for Meta as a primary channel, plus practical experience with Snapchat or TikTok Ads
• Fluency in creative metrics (hook rate, hold rate, thumbstop rate, creative win rate, CTR, CPA, ROAS) as everyday decision-making tools, and a clear view of how creative connects to registration, first purchase, revenue, and LTV
• A track record of concepts you personally scaled, backed by real numbers
• Daily, practical use of AI tools for creative generation and research (Midjourney, Runway, Kling, Pika, HeyGen, Krea, or similar), with your own workflows or prompts you can walk us through
• Upper-Intermediate English (B2+)

Would be a plus

• Experience in social discovery or social networking niches, and familiarity with credit-based or transactional monetization models
• Background in User Acquisition or video production (shooting, editing, directing)
• Experience hiring creative marketers or designers and building AI-driven production pipelines or automations (n8n, Make)

What we offer

Care and support:

• 20 paid vacation days, 15 sick leave days, and 6 additional days off for family events
• 100% medical insurance coverage
• Sports and equipment reimbursement
• Team building events, corporate gifts, and stylish merch

• Performance-oriented reviews and Individual Development Plans (IDPs)
• Reimbursement for professional courses and English classes
• Corporate library, book club, and knowledge-sharing events
• AI is an integral part of our work culture. We invest in modern AI tools, equip our teams with the skills to use them effectively, and foster an environment where technology helps people achieve better results faster
