Jobs at Djinni

We are looking for a Head of Revenue Growth. You will own the full revenue engine across a portfolio of mature, monetizing platforms in social discovery and live-streaming, not one funnel, not one channel, but the whole picture. That means P&L accountability, paid acquisition across mobile and web, monetization strategy, product growth experiments, and the unit economics that tie it all together. You will work directly with the CEO, Head of Marketing, Head of DS & AI, and five Product Owners . We move fast, cut through bureaucracy, and give real ownership to people who can handle it. If that sounds like your kind of environment, read on.

About United Tech: We are a global IT product company building the next generation of mobile and web platforms in live-streaming and social networking. Our products connect millions of users across North America, Europe, LATAM, and MENA, and we have been profitable doing it. Founded in Ukraine, operating worldwide, with a market we expect to exceed $206B by 2030. We are not chasing that number, we are already in the middle of it.

In this role, you will

• Own the full revenue funnel and its P&L from acquisition to repeat payments — accountable to ROAS LT0/LT7/LT30 targets and blended payback
• Develop and execute the revenue growth strategy across paid traffic (mobile + web), product growth, and monetization, owning channel mix, budget allocation, and scaling decisions
• Generate, prioritize, and validate growth and monetization hypotheses with Product and Tech, driving prioritization of Product Owner backlogs for growth work
• Lead A/B and multivariate testing across onboarding, activation, paywalls/coin-packs, and pricing
• Own unit economics (CAC, LTV, ARPU, ARPPU, ROAS, payback) and the cohort LTV model; ensure scalable, margin-aware growth given streamer revshare
• Partner with Payments and Risk to maximize payment conversion and approval rates, and expand margin-accretive web/direct billing

• Build revenue dashboards and a single source of truth for performance metrics, with shared metric definitions and transparency across teams

   

It's all about you

• Strong hands-on experience in growth / performance marketing for dating, social discovery, live-streaming, or IAP products, across both mobile apps and web funnels
• Demonstrable strong command of unit economics (CAC, LTV, ARPU, ARPPU, ROMI, payback, contribution margin) — able to build the model, not just read it
• Proven experience scaling paid acquisition on mobile and web: Google, Meta, TikTok, and programmatic/DSP (e.g., Moloco) are a strong advantage
• Solid experience with A/B testing, experimentation frameworks, and funnel optimization
• Strong analytical foundation: SQL and BI tools (e.g., Looker/Tableau), cohort analysis, predictive LTV; working knowledge of mobile attribution/MMP (AppsFlyer/Adjust), web analytics and server-side tracking (GA4, Meta CAPI), web2app deep-linking, and incrementality testing
• Experience managing growth, marketing, or media-buying teams
• Advanced user of Anthropic and OpenAI tools
• Fluent in English (B2+) and Ukrainian

Would be a plus

• Experience in payments, payment product management, or working closely with PSP/acquiring teams

About the team

We are a focused engineering team of 5 to 9 people at a multi-product tech SaaS company. We work across personalization, recommendation, fraud detection, and some GenAI, through real-time, near-real-time, and batch
pipelines. The team is a blend of Python backend engineers, ML engineers, QA (manual and automation), a data engineer, and data scientists. Our shared mandate is to take experimentation from our data scientists and turn it into
robust, production-grade systems, either as standalone services or integrated into wider platforms.

The role

You will be a senior engineer on the team, building and operating backend systems and setting a high bar through your work. You will contribute significantly to architecture and technical direction and strongly influence how we build, working alongside other senior engineers and a hands-on engineering manager, while staying hands-on across the hardest problems. The systems you work on are either part of a larger SaaS backend or run as standalone services: batch and event-driven pipelines, stream consumers, feature stores, REST APIs, and background workers.
 

 Responsibilities

• Contribute significantly to the architecture and implementation approach for the team's backend systems, and influence technical direction
• Design and build production Python services: APIs, stream consumers, pipelines, feature stores, background workers
• Set and uphold engineering standards: code quality, testing, observability, deployment discipline
• Take ownership of deployment and release, partnering with DevOps on Docker, Kubernetes, and CI/CD
• Productionize data scientists' experimentation into reliable services
• Raise the technical bar through review, mentorship, and example
• Take part in the team's on-call rotation for the systems you build and operate
• Partner with product and business stakeholders to shape and scope work

 
Requirements

• 5+ years of backend engineering experience
• Strong Python: async, data processing, Redis, Kafka, and database clients, PySpark
• Strong relational database skills, plus Redis and Kafka (design and performance tuning)
• Good working knowledge of Docker, Kubernetes, and CI/CD, enough to partner well with DevOps
• Experience contributing to and influencing architecture and implementation approach for a team
• Deployment and release ownership
• Product mindset, comfortable speaking to customers and business stakeholders

Nice to have

• Databricks experience
• Experience building LLM-powered systems, including human-in-the-loop and agentic workflows
• Fraud detection, recsys, or personalization systems experience
• Prometheus and Grafana
• SaaS or high-scale product domain experience

Why join us

• Work on high-scale, high-throughput backend systems
• Broad range of technologies, stacks, and problems
• Take experimentation from data scientists and turn it into production systems
• A strong engineering culture that values technical depth and ownership
• A distributed team across Dubai and Europe

You will get:

• Work in a technically strong environment with modern stack and mature Agile culture;
• High autonomy, decision-making authority, and close cooperation with leadership;
• A position in a product development company with a dynamic environment and several concurrent projects;
• Opportunity to contribute (your ideas for improvement implementation);
• Continuous self-improvement and growth, including budget for certifications and courses;
• Competitive salary plus annual bonus, based on individual, team, and company performance;
• Company prepaid AI agent;
• Medical insurance coverage;
• English language courses;
• Wellbeing package: online-yoga classes, Yakaboo, BetterMe App: Health Coaching, BetterMe App: Mental Health;
• Corporate events and fun team-building activities;
• Remote-first culture (with a possibility to work from our Kyiv office)
