Jobs at Djinni

Join a Company That Invests in You

Seeking Alpha is the world's leading community of engaged investors. We’re the go-to destination for investors looking for actionable stock market opinions, real-time market analysis, and unique financial insights. At the same time, we’re also dedicated to creating a workplace where our team thrives. We’re passionate about fostering a flexible, balanced environment with remote work options and an array of perks that make a real difference.

What We're Looking For

Do you look at websites and think about how they might be personalized? Do you use websites and apps and think about how their features have been designed to be best for a lot of different users? Do you read articles with statistics and think about how they may be misinterpreting the data to get their results? If these things describe you, and if you’re great at SQL and have experience analyzing website data, you’re someone we want to talk to.

We’re looking for a Senior Data Analyst with experience analyzing website data. Our data analyst team analyzes everything on our website, not only for their immediate use but also for how they connect to high-level company KPIs. Our Analysts analyze raw data, not only pre-aggregated data, to extract just the right information and diagnose what is happening on our site.

The role requires understanding web development and how data is gathered, analysis of site usage and a/b tests, data visualization, and how different kinds of data can be presented most clearly, and business KPIs and how they are measured.

But more than that, we’re looking for experienced analysts who can bring us new ideas about how to analyze and extract insights from website data. Our ideal candidates have measured KPIs that we haven’t measured or used new ways to explain user retention, or analyzed features of users' data that we haven’t analyzed.

The best thing about our work is that we’re part of an incredibly data-driven company. Everyone from the CEO down uses data every day. The data teams are involved in every single thing the company does.

What You'll Do

• Analyzing the behavior of users on our site and apps:

-Build and maintain dashboards that visualize the usage of single or multiple features and how that usage drives company KPIs.

-Answer questions about site usage or user behavior based on deeper analyses.

• Analyze and track high-level KPIs such as conversion, retention, churn, recurring revenue, engagement, cross-device usage, e-mail and notification usage, and more.
• Communicate with business stakeholders on analysis results, how they relate to business, and what business suggestions result from the analysis.
• Run the whole data flow for site and app features, from defining KPIs, specifying data collection for development team implementation, and building and maintaining iterative versions of dashboards with both low-level and high-level views of collected data.
• Split tests of product features:

-Design a test with clear success criteria

-Monitor test integrity

-Analyze results and give recommendations

-Use segmentation and clear cohort analysis to validate significant conclusions

-Conduct exploratory analysis to identify trends and opportunities

Requirements

• A minimum of 5 years in a B2C website-related Data Analyst position
• Strong SQL skills with experience writing complex and efficient analytical queries
• Demonstrated experience with working in English directly with business stakeholders, understanding their needs, and explaining results
• Understanding of website development and operations and how they connect to data gathered.
• Experience with data visualization tools (Looker/Tableau/PowerBI, etc.)
• Experience with report writing and technical requirements analysis, business process modeling/mapping, methodology development, and data modeling

The company is seeking a creative and detail-oriented Tech Art Auditor to join a team dedicated to producing engaging mobile game ads using cutting-edge AI technology. This role focuses on reviewing, refining, and enhancing AI-generated 2D and 3D assets to ensure high-quality visual output for mobile game advertisements.
 

This is an excellent opportunity for candidates eager to gain hands-on experience in tech art, 3D/2D production, and AI-assisted content creation within a dynamic and fast-paced environment.

 

What You’ll Do:
 

• Evaluate AI-Generated Content
  Review AI outputs, spot imperfections, and provide actionable feedback to improve overall quality.
• 3D Editing in Blender
  Modify and optimise low-poly 3D models, adjust shading, and ensure assets are production-ready.
• 2D Image Editing & Asset Creation
  Edit images, create visual elements, and prepare polished assets for mobile game ads.
• Work With Generative AI Tools
  Use AI-driven software to generate, refine, and enhance art assets efficiently.
  
   

What You’ll Bring:
 

Core Skills Required:

• Blender expertise for model editing, shading, and optimisation
• 2D editing proficiency (image editing & asset creation)
• Familiarity with generative AI tools and workflows
• Strong attention to detail and ability to critique, refine, and polish visual assets
• Passion for mobile gaming - especially casual and mid-core titles
  
   

Why This Role Stands Out:
 

• Work with innovative AI technologies shaping the future of game advertising
• Join a creative, fast-moving environment that encourages experimentation and growth
• Build valuable experience across 3D, 2D, and AI-driven art production
• Ideal for candidates at the beginning of their tech art career who want meaningful, practical hands-on experience
• Long-term cooperation, B2B collaboration, remote flexibility, and loyal management
  
   

Why You Should Submit Your CV & Contact Information:
 

To be considered, candidates must leave their CV and contact details so the team can:

• Evaluate your technical skills and portfolio
• Match your experience to the right projects
• Invite you for next-step discussions
• Keep in touch regarding future AI-art opportunities
  
   

Leaving your CV ensures you don’t miss out on a role that can accelerate your growth in tech art and AI-assisted asset creation.
