Your mission – maximize the Net Profit and Long-Term Value (LTV) of your multi-platform portfolio of apps across iOS, Android, and web by aligning product innovation with data-driven performance marketing.

Unlike a solo founder, you aren’t starting from zero. As a Business Unit CEO, you have:

• 3+ years in leadership roles with direct P&L ownership (CPO, CMO, GM, CEO, Product Director, Head of Product, Head of Marketing, etc.)

• Proven 0→1 and scale-stage experience: launching new units, restructuring businesses, scaling early-stage products to meaningful revenue, or founding a startup
• Strong financial acumen: you live in the dashboards. You understand the nuances of cohorts, LTV/CAC ratios, and churn rates in a subscription-based model
• Mentality: ownership, clarity, decisiveness, speed, and persistence
• Entrepreneurial mindset

What we offer:

• Full strategic and operational ownership of a multi-million ARR business unit
• Competitive fixed compensation + performance-based bonus + long-term incentive structure
• The opportunity to scale a category-leading product portfolio into a global market-defining player

This is a fully hands-on role. You'll be responsible for designing campaign mechanics, building them in the CRM platform, launching, analyzing results, and continuously improving performance.

As the team grows, you'll become part of the Sports Retention Tribe led by a dedicated Team Lead.

Sports retention revolves around major sporting events. IPL, World Cups, Champions League, domestic leagues, and other tournaments define the business rhythm. Success in this role means preparing campaigns well in advance of key events while maintaining player engagement during quieter periods.

Responsibilities

Loyalty Program

• Design loyalty mechanics, levels, rewards, and progression.
• Analyze program performance and implement improvements based on data.
• Ensure seamless integration between loyalty initiatives and gamification mechanics.

• Manage the full campaign lifecycle:
  • Idea;
  • Mechanics;
  • Segmentation;
  • CRM setup;
  • Launch;
  • Post-campaign analysis.
• Build evergreen campaigns to maintain engagement between major sporting events.
• Prepare briefs for the Content team, including campaign messaging and creative requirements.

Segmentation & Experimentation

• Build audience segments using RFM, lifecycle, and player activity.
• Use control groups to measure campaign uplift.
• Run A/B tests for campaign mechanics, offers, and communications.

Analytics & Reporting

• Monitor retention KPIs in Smartico Data Studio.
• Analyze campaign performance, uplift, bonus costs, and ROI.
• Prepare regular reports for management.
• Plan bonus budgets and justify campaign economics.

Requirements

• 2+ years of experience in CRM or Retention within the iGaming industry.
• Hands-on Sportsbook retention experience is mandatory.
• Proven experience launching end-to-end retention campaigns.
• Practical experience with CRM platforms such as:
  • Smartico (strong advantage);
  • Optimove;
  • Fast Track;
  • Symplify;
  • or similar platforms.
• Hands-on experience with:
  • audience segmentation;
  • customer journeys;
  • bonus mechanics;
  • gamification.
• Strong understanding of sportsbook player behavior and lifecycle.
• Experience with cohort analysis, A/B testing, and control groups.
• Ability to work independently, prioritize tasks, and make data-driven decisions without daily supervision.
• English level sufficient for reading documentation and professional communication.

Nice to Have

• Experience working with the Indian market.
• Understanding of cricket audiences and the IPL ecosystem.
• Experience launching or improving loyalty programs.
• Hands-on experience with gamification modules (missions, tournaments, leaderboards).
• Understanding of Responsible Gaming principles.

We Offer

• Fully remote work.
• Opportunity to build sportsbook retention almost from scratch.

• • Career growth within the Sports Retention Tribe as the team expands.

You will own the part of the product people actually look at: the dashboards and charts that operators watch 24/7 and that clients judge the whole platform by. Right now the data is there and the screens are not - raw telemetry streams in, and nobody has turned it into something a human can read at a glance, in a control room, at 3 a.m.

Day to day, this means: you take a requirement as rough as "operators need to see status", sketch how the screen should work, design the layout and hierarchy yourself, build it, wire up the live charts, ship it. No dedicated designer in the loop, no mockup handed to you. You own the screen end to end.

What you'll do

• Take over the existing dashboard and raise its visual and UX quality: consistent layout, clear hierarchy, a reusable component structure instead of one-off screens.
• Build the telemetry visualizations: time-series charts of live metrics per asset - updating in real time, zoomable and pannable over large datasets, readable on a control-room wall display.
• Design and implement the operator screens for the 24/7 use case: status at a glance, alarm visibility, dark theme, no ambiguity under stress.
• Establish a lightweight design workflow: quick mockups before implementation, a consistent style guide, reusable chart configurations.
• Work with the backend team on the data contract: what each endpoint must return for the screens, without over-fetching.

Must have

• 4+ years of frontend experience with strong vanilla fundamentals: semantic HTML, modern CSS (grid/flexbox, responsive layout), JavaScript you write without reaching for a framework by default.
• Real data-visualization experience with a serious charting library (amCharts, ECharts, Highcharts, Chart.js, D3): time-series, live-updating data, zoom/pan over large datasets, and the judgement to pick the right chart for the data.
• UI/UX grounding - decisions based on design reasoning, not decoration: layout, visual hierarchy, typography, spacing, colour. You can explain why a screen looks the way it does.
• Ability to work from rough requirements and deliver a designed, working screen without a designer.
• English B2 or above (documentation, day-to-day communication).

Nice to have

• amCharts 5 specifically.
• HTMX / Alpine.js or similar lightweight interactivity.
• WebSockets / SSE for live data streams.
• Figma (or similar) for quick mockups before code.
• Tailwind / Bootstrap, or experience building a small design system.
• Accessibility (WCAG) and dark-mode design - control rooms run dark themes.
• Dashboards for monitoring, industrial, logistics or finance - any data-dense UI domain.

What we care about beyond skills

• Empathy for the actual end user: operators on night shifts, not a demo audience.
• Taste with pragmatism: ships good-enough-and-improving, not pixel-perfect six weeks late.
• Takes design feedback without ego, and can defend a design decision with more than "it looks nice".

Probably not your role if

• You only build inside a framework and can't work close to plain HTML/CSS/JS.
• You implement other people's mockups but can't sketch a screen yourself.
• The charts in your portfolio are default-config demos, never adapted to the data or the reader.
• You design marketing pages, not working screens with high information density.
• You treat operator feedback as "users don't understand design".

• Project Description:

  The primary goal of the project is the modernization, maintenance and development of an eCommerce platform for a big US-based retail company, serving millions of omnichannel customers each week.
  
  Solutions are delivered by several Product Teams focused on different domains - Customer, Loyalty, Search and Browse, Data Integration, Cart.
  
  Current overriding priorities are new brands onboarding, re-architecture, database migrations, migration of microservices to a unified cloud-native solution without any disruption to business.

• Responsibilities:

  We are looking for Senior Data Engineer to implement a solution for a big retail company. The main focus is to support processing of big data volumes and integrate solution to current architecture.

• Mandatory Skills Description:

  • Overall years of experience required 8+
  • Strong, recent hands-on expertise with Azure Data Factory and Synapse is a must (3+ years).
  • Strong expertise in designing and implementing data models, including conceptual, logical, and physical data models, to support efficient data storage and retrieval.
  • Strong knowledge of Microsoft Azure, including Azure Data Lake Storage, Azure Synapse Analytics, Azure Data Factory, and Azure Databricks, pySpark for building scalable and reliable data solutions.
  • Extensive experience with building robust and scalable ETL/ELT pipelines to extract, transform, and load data from various sources into data lakes or data warehouses.
  • Ability to integrate data from disparate sources, including databases, APIs, and external data providers, using appropriate techniques such as API integration or message queuing.
  • Proficiency in designing and implementing data warehousing solutions (dimensional modeling, star schemas, Data Mesh, Data/Delta Lakehouse, Data Vault)
  • Proficiency in SQL to perform complex queries, data transformations, and performance tuning on cloud-based data storages.
  • Experience integrating metadata and governance processes into cloud-based data platforms
  • Certification in Azure, Databricks, or other relevant technologies is an added advantage
  • Experience with cloud-based analytical databases.
  • Experience with Azure MI, Azure Database for Postgres, Azure Cosmos DB, Azure Analysis Services, and Informix.
  • Experience with Python and Python-based ETL tools.
  • Experience with shell scripting in Bash, Unix or windows shell is preferable.
  • Demonstrated ability to lead cross-functional engineering teams, define technical strategy and architecture, drive delivery of complex data platforms, mentor engineers, and effectively communicate with stakeholders at all organizational levels.

• Nice-to-Have Skills Description:

  • Experience with Elasticsearch
  • Familiarity with containerization and orchestration technologies (Docker, Kubernetes).
  • Troubleshooting and Performance Tuning: Ability to identify and resolve performance bottlenecks in data processing workflows and optimize data pipelines for efficient data ingestion and analysis.
  • Collaboration and Communication: Strong interpersonal skills to collaborate effectively with stakeholders, data engineers, data scientists, and other cross-functional teams.
  • Ability to plan, estimate and track progress of implementing features
  • Computer Science and data science academic and education credentials
