Jobs at Djinni

We are seeking a Senior Python + Data Systems Engineer for a US-based SaaS company in marketing analytics.

Please note that the working hours for this position are until 11 PM Kyiv time.

About the Client

The client is an American SaaS company in marketing analytics. Its platform helps e-commerce brands understand which ad spend truly drives revenue. It collects tracking data, combines it with data from major ad platforms, and uses ML modeling to turn it into reporting.

The company’s customers spend millions per month on advertising, so data volumes are large and business decisions depend on data accuracy.

About the Project

There are several projects in progress:

• Conversion API (main project): reprocessing tracking signals and delivering them to ad-platform APIs in real time. Each platform’s API works differently and has its own quirks, so integrations require careful work. Stack: Python streaming, Google Pub/Sub, Shopify JS tracking.
• Mobile attribution SDK (greenfield): a new SDK for JavaScript and iOS.
• Analytics data pipelines: pipelines built as part of the SaaS product, not internal BI.
• Full-stack product development: application features and integrations.

Requirements:

• 7+ years of commercial experience with Python in production at Senior level. 
• Strong SQL skills. You are confident working with complex queries and large data volumes, as data accuracy directly drives clients’ business decisions
• Hands-on experience building and maintaining integrations with third-party APIs
• Experience with streaming or event-driven systems (message queues, pub/sub, real-time data processing), as the main project delivers tracking signals to ad platforms in real time
• Experience with GCP and BigQuery
• Track record of building customer-facing products, not just internal tools or dashboards
• Experience with SaaS products used by external customers is a strong fit
• Ability to design engineering abstractions and discuss architectural decisions with the team, explaining trade-offs
• Fluent English (C1) for daily communication with the US team: syncs, technical discussions and written communication

Nice-to-have:

• Experience with Snowplow or OpenSnowcat
• Experience with Conversion APIs
• Background in marketing analytics and e-commerce

• Experience with Google Pub/Sub and Airflow

   

Responsibilities:

• Work as a backend-heavy engineer on integrations, APIs, services and streaming pipelines
• Develop the Conversion API: reprocess tracking signals and deliver them to ad-platform APIs in real time, handling the specifics of each platform’s API
• Build analytics data pipelines as part of the SaaS product
• Contribute to architecture discussions and engineering abstractions

Responsibilities: 

1. Ownership

   Be the analytics counterpart for a product domain 1:1 chat, content packs, negotiations, live streaming — you become the person PMs and engineers come to for any number in that area, and the person accountable when it's wrong.

2. Experiments

   Run A/B tests on product features, end to end Turn a product hypothesis into a test: primary and secondary metrics, the minimum effect worth detecting, and the audience. Confirm the population split and assignment events are genuinely correct before trusting the readout. Monitor it while it runs, then deliver a clear ship / don't-ship call and the reasoning behind it. This is a large part of the job, not an occasional project.

3. Pipelines

   Build and maintain the datasets behind your domain Write production transformations as SQL and YAML pipeline config, with freshness, uniqueness and validity checks. Your work goes through code review like any engineer's.

4. Events

   Specify instrumentation before it's built Write the BI event spec for new features across Android, iOS and Web; then verify after release that events actually fire the way the spec said, and chase the gaps when they don't.

5. Dashboards

   Own dashboards and the models under them

   Including retiring the ones nobody opens. A dashboard with no reader is a cost, not an asset.

6. Analysis

   Investigate what moved and why Revenue and conversion anomalies, feature performance, behavioural questions from PMs. Present findings to people who will act on them.

7. Incidents Size production incidents under time pressure When something breaks, you're asked how many users were affected and for how long — quickly, and precisely enough to defend the number when engineering disagrees with it.
8. Cost Keep query and pipeline cost honest Partitioning, clustering, and knowing why a query scans what it scans. Warehouse capacity is shared and finite; an expensive pipeline is everyone's problem.

Requirements:

• Advanced SQL, including window functions and multi-source joins — and the ability to reason about what a query costs, not only whether it returns.
• A strong experimentation background. Hypothesis testing, confidence intervals, power and minimum detectable effect — and the failure modes: peeking at a running test, multiple comparisons, hunting for a segment where the result works. You should also be the kind of person who checks that the experiment itself is sound before trusting its numbers.
• 3+ years as a product or data analyst on consumer products, with real exposure to both mobile and web.
• Critical use of AI analytics tooling. We use an internal Claude-based layer over BigQuery heavily. We want someone who checks what it produces before passing it on.
• Comfort shipping code: git, merge requests, reading and reviewing someone else's SQL. You'll write production pipeline code, not only notebooks and queries.
• Working knowledge of product event tracking: what a well-specified event looks like, and why the same event behaves differently across platforms.
• English at B1 or above. You'll write specifications that engineers build from and present findings to product stakeholders, so clear written English matters more than fluent speech.

Strong advantage

• BigQuery specifically — partitioned tables, clustering, slot-based pricing.
• Airflow, dbt, or another orchestrated transformation framework.
• Having been the analyst on a production incident, not only in the post-mortem.

Nice to have

• Python with the usual statistical libraries — pandas, scipy, stats models.
• A BI tool such as Looker, Tableau, or Power BI — having built the models and dashboards, not only read them. We use Looker today but are moving off it, so the particular tool matters much less than having done the work in one.
• Data quality tooling such as Soda or Great Expectations.
• Experience in social, live-streaming, gaming or another engagement-driven consumer product.

About the Role

We are looking for a Retention Specialist who will take ownership of retaining the sports betting audience through a loyalty program, gamification, and event-driven and seasonal campaigns.

This is a full-cycle, hands-on role: you come up with the mechanics yourself, build them in Smartico (segments, journeys, bonuses, gamification), launch them, and analyze the results yourself.

An important part of the context: there is currently no direct lead overseeing this role, so no one will be assigning tasks to you. You will set your own priorities based on the sports calendar, retention metrics, and insights from the data. Later, a Lead of Sports Retention Tribe will join and you will become part of their team, but during the first few months, this role is best suited for someone who does not need daily management.

Vertical specifics: sports retention revolves around the sports calendar. IPL, World Championships, major tournaments, and other key events create peak periods that require preparation weeks in advance. Between these peaks, the audience needs to be retained through regular engagement mechanics. The ability to work effectively within this rhythm is at the core of the role.

Responsibilities
Sports Loyalty Program
Own the sports loyalty program: mechanics, tiers, rewards, and economics.
Continuously develop and optimize the program: identify what drives retention, what does not work, and what should be changed — all backed by data.
Ensure alignment between loyalty and gamification so that the mechanics reinforce rather than conflict with each other.
Gamification
Design and launch gamification mechanics in Smartico: missions, tournaments, achievements, and leaderboards tied to sports events.
Connect gamification with bonus mechanics and the loyalty program.
Iterate based on engagement results: a mechanic either improves the target metric or is discontinued.
Event-Driven and Seasonal Campaigns
Own the sports event calendar: plan campaigns for key events such as IPL, global tournaments, and local peak periods weeks in advance rather than reacting at the last minute.
Manage the full campaign cycle: idea → mechanics → segmentation → setup in Smartico → launch → post-campaign analysis and economics.
Run seasonal campaigns between major peaks to retain and engage regular users during quieter periods.
Prepare briefs for the Content team, including requirements for copy and creatives.
 

Segmentation & Experimentation
Work with sports audience segmentation based on RFM, activity, and lifecycle. Every campaign should have a clearly defined segment — no generic “send to everyone” campaigns.
Use control groups by default: campaign impact should be demonstrated through uplift, not just absolute numbers.
Run A/B tests of mechanics, offers, and communications.
Analytics & Reporting
Regularly monitor retention metrics for sports cohorts using Smartico Data Studio.
Conduct post-campaign analysis for every campaign, including engagement, uplift, bonus costs, and overall campaign economics.
Provide regular reporting to management on the performance of the sports vertical.

The bonus budget is managed at a higher level within the organization. You will plan campaign costs and justify their economics, while final approval remains with the manager.

Role Metrics
Sports cohort retention: D7/D30 redeposit rate among sports bettors.
Event activation: percentage of the user base engaged in event campaigns and their activity during peak periods.
Bonus cost efficiency: campaign uplift versus control groups and cost per retained player.
 

Requirements
2+ years of experience in Retention/CRM within iGaming, including mandatory hands-on experience specifically with the sports betting vertical. Be prepared to discuss 2–3 campaigns: the event, mechanics, target segment, and achieved uplift.
Hands-on experience working with a CRM platform. Smartico is a strong advantage; Optimove, Fast Track, and Symplify are also relevant. You should be comfortable working with segments, journeys, bonus mechanics, and gamification.
Strong understanding of the betting audience: what drives sports bettors, how their behavior differs from casino players, and how their engagement cycle is structured around sporting events.
Solid analytical foundation: cohort analysis, control groups, dashboard interpretation, and basic bonus economics.
High level of autonomy: ability to build your own work plan based on the sports calendar and performance metrics without relying on externally assigned tasks. This will be assessed through a case during the interview.
English: sufficient for reading documentation and handling day-to-day professional correspondence.
 

Nice to Have
Knowledge of the Indian market and cricket audience, particularly IPL as the key annual peak.
Experience launching or relaunching loyalty programs.
Experience with gamification modules such as tournaments, missions, and leaderboards.
Understanding of responsible gaming restrictions related to communications and bonuses.
What We Expect in the First 3 Months

Within the first three months, we expect you to have:

Built and implemented an event calendar covering the next quarter.
Launched several full-cycle campaigns with post-campaign analysis and control groups.
Conducted a diagnostic review of the sports loyalty program and developed a data-backed improvement plan, including its economics.

Performance will be evaluated based on retention metrics and campaign uplift — not on the number of campaigns launched.

We offer
Fully remote work opportunity
Enhanced leave benefits:
20 days of paid vacation
5 paid days off
14 paid sick leaves
Company clubs & communities
Celebration gifts for personal milestones
Corporate online events, raffles & challenges
Corporate English program
Corporate yoga classes
Team-building activities
Coworking compensation
Training and development programs (internal & external).

About the Role

We are looking for a proactive and creative Retention professional who can join our team and put their modern marketing expertise into practice. We stay on top of market trends and follow established CRM framework standards.

The Retention Specialist will play a key role in shaping the strategy for engaging our customer base with promotional content, setting up and improving internal processes within the department, and, at times, making decisions with incomplete information.

Responsibilities
Plan the promotional and communication calendar;
Create and test customer segments, determining which customers to retain or reactivate and how;
Launch end-to-end promotional and bonus campaigns;
Prepare technical briefs for marketing content, including banners, emails, and copy;
Manage customer communications across multiple channels: SMS, email, push notifications, call center, and in-app messaging;
Analyze campaign performance and identify growth opportunities;
Develop and test hypotheses to improve existing retention mechanics;
Collaborate cross-functionally with Product, IT, Analytics, Customer Support, Design, Risk, and Marketing teams.
Requirements
Experience working with ESP, CRM, and/or CDP platforms; knowledge of Smartico would be a plus;
Understanding of marketing and retention mechanics in the betting and iGaming industries;
Strong analytical skills and experience with Power BI or Tableau;
Advanced Excel skills are required, including VLOOKUP and PivotTables;
Ability to analyze and segment customer databases and identify growth opportunities;
Understanding of key product metrics;
Knowledge of standards and benchmarks for direct communication channels;
Upper-Intermediate English (B2) or higher — you should be able to review English-language content, communicate with external vendors/contractors, and prepare clear technical briefs.
Nice to Have
Previous experience in betting and/or iGaming;
Experience working in an Agile environment;
Strong Excel reporting skills and the ability to create clear, visually appealing, and useful reports;
Basic understanding of statistics and probability theory;
A good eye for design and the ability to distinguish high-quality content from poor-quality content and provide clear feedback for revisions.

We offer:
-The opportunity for remote work from anywhere in the world.
-A friendly atmosphere and people who love their work.
-Managers interested in team member development.
-20 working days of vacation, 5 days off, and sick leave compensation.
 

About the Role

We are looking for a VIP Retention Lead who will take ownership of VIP customer retention through CRM.

This is not a VIP Host role — you will not be responsible for direct one-to-one communication with players. Your role is systematic and data-driven: VIP segmentation, lifecycle management, personalized retention mechanics and CRM campaigns through Smartico, as well as managing the economics of retaining the most valuable part of the customer base.

Why this role is critical: the VIP segment generates a disproportionately large share of product activity and revenue. Losing a single whale can have the same financial impact as losing hundreds of regular players. This requires a different level of precision — not simply running campaigns for a segment, but building a system capable of identifying churn risk among top players days before they actually leave.

This is a senior ownership role. You will not simply execute predefined tasks — you will design the VIP retention system, defend its economics and strategy to the Head of CVM, and take responsibility for the segment’s performance.

Responsibilities
VIP Lifecycle Management
Own the VIP lifecycle end-to-end. VIP statuses are assigned according to predefined criteria; your responsibility begins with what happens to those players afterward.
Develop segmentation within the VIP base based on tiers, behavioral profiles (Sports / Casino / Mixed), and lifecycle stages — VIP should not be treated as a single homogeneous segment.
Build and manage a pre-VIP pipeline to systematically identify and nurture high-potential players approaching VIP status.
Offer Matrix & Retention Economics
Design a structured VIP offer matrix defining which mechanics and rewards each tier receives depending on player behavior.
Present and defend the offer matrix and its economics to the Head of CVM. Once approved, campaigns should operate within this framework without requiring individual approvals.
Manage VIP bonus economics by measuring uplift against control groups, calculating retention costs, and preventing over-incentivization of players who would have remained active without additional bonuses.
Churn Prevention & Reactivation
Build VIP churn alerts based on behavioral signals such as changes in activity frequency, spending, and session patterns. A decline in activity from a top player should be treated as an incident requiring timely action rather than simply appearing in a monthly report.
Develop retention campaigns for different risk stages, ranging from soft interventions at early warning stages to dedicated reactivation programs for dormant VIPs.
Build VIP reactivation as a separate systematic process with its own economics and performance measurement.
Campaigns & Mechanics
Manage the complete campaign lifecycle directly in Smartico, including segments, journeys, personalized bonus mechanics, and VIP gamification.
Develop cross-vertical mechanics between Sports and Casino while carefully expanding player behavior without excessive pressure.
Synchronize VIP campaigns with major sporting events such as the IPL and other major tournaments, as well as key Casino activities.
Prepare briefs for the Content team for VIP communications, where tone, accuracy, and personalization standards are particularly important.
Responsible Gaming
Own the Responsible Gaming framework within VIP retention. High player turnover and spending can create increased problem-gambling, legal, and reputational risks.
Ensure players showing RG risk signals are excluded from promotional campaigns and that self-exclusion requirements are strictly respected.
Analytics & Reporting
Monitor VIP segment performance through Smartico Data Studio, including retention, AV/NGR dynamics, and migration between VIP tiers.
Conduct post-campaign analysis using control groups by default.
Provide regular reporting to the Head of CVM on VIP segment health, performance, and economics.
Key Performance Metrics
 

VIP Retention: churn rate among top tiers and VIP player lifetime.
Value Retention: AV/NGR dynamics and upward vs. downward migration between VIP tiers.
Churn Response Speed: percentage of at-risk VIPs identified and targeted before actual churn.
Retention Economics: campaign uplift versus control groups and cost per retained VIP.
 

Requirements
4+ years of Retention/CRM experience in iGaming, including proven experience specifically with VIP/high-value customer segments. You should be able to describe a retention system you built, including churn detection, offer logic, and measurable impact on churn.
Experience designing retention systems, not only executing campaigns, including segmentation models, offer matrices, and churn alerting.
Strong hands-on experience with CRM platforms. Smartico is a major advantage; experience with Optimove or Fast Track is also relevant.
Strong analytical skills, including cohort analysis, LTV logic, control groups, and bonus economics, with the ability to justify retention budgets to senior management.
Understanding of both Sports Betting and Casino audiences and the differences in their behavior.
Strong understanding of Responsible Gaming, including the ability to recognize where retention activities should stop due to player protection concerns.
English sufficient for professional written communication and reading technical/product documentation.
 

Nice to Have
Experience with the Indian market.
Experience building pre-VIP pipelines or programs for identifying high-potential players.
Experience working with predictive churn models.
Experience collaborating with VIP Hosts or Personal/VIP Account Managers.
Expected Results

Within the first three months, we expect:

A comprehensive diagnosis of the VIP segment, including its structure, churn points, and current retention economics;
A functioning VIP churn-alert system;
A structured and approved VIP offer matrix implemented in production;
Initial campaigns completed through the full lifecycle with control groups and measurable results.

We Offer:
 Remote work from anywhere in the world.
 Fast decision-making without bureaucracy.
 Friendly atmosphere among people passionate about their work.
 Qualified managers invested in your growth.
 20 paid vacation days, 5 day-offs, and paid sick leave.

You’ll report to the CEO of the BU and lead a team of growth managers, who are already delivering solid results. Your job is to help them aim higher and build the systems that make strong performance repeatable.

What you will do:

• Own web revenue performance across the unit and set the direction for how the team moves these numbers
• Audit current web growth processes and build the strategy from there
• Lead the shift to web-to-web as the primary growth format — scaling what works and fixing what doesn’t
• Lead, mentor, and develop a team — raise the hard skills bar, drive accountability, and create the kind of environment where ambitious targets feel energizing rather than exhausting
• Work closely with heads of product, marketing, analytics, and engineering to move initiatives from strategy to execution

What you should have:

• 5+ years of experience in growth or product marketing within subscription-based environments, with a strong focus on web and web-to-web
• 3+ years of leadership experience managing growth teams and driving cross-functional collaboration across product, marketing, analytics, and engineering
• Proven track record of taking subscription products through different stages: you’ve launched from scratch, scaled what was already working, and diagnosed why something that should be growing isn’t
• Deep understanding of unit economics and web growth metrics: CAC, LTV, ROAS, retention, churn, funnel conversion — and how they connect to each other
• Understanding of how LTV prediction models are built and what drives them
• Experience with payment infrastructure: you know how subscription billing works end-to-end
• Hypothesis-driven approach to growth: you build experiments, read results honestly, and iterate fast
• Sharp analytical thinking — you work comfortably with numbers, notice what others miss, and can translate data into decisions
• Solid people management instincts — you know how to develop talent
• Strong written and spoken English

What we offer:

• Results-oriented colleagues committed to scaling impactful products. Your team will help you achieve the most ambitious goals
• Remote-friendly work environment with high autonomy and minimal bureaucracy
• Competitive fixed salary+ generous performance-based bonus
• Medical insurance (depending on the location)

• Paid vacations, sick days, and other benefits
