Strim Duo is a creative digital studio based in Limassol, Cyprus. We specialize in social game development, product engineering, UX/UI design, custom software solutions, mobile apps, and post-launch product support.
Our mission is to build products that work seamlessly across devices, delivering engaging experiences for millions of users worldwide.

The expertise we’re looking for:

• 3+ years in product or data analytics.
• Strong SQL: complex joins, window functions, query performance on large datasets (ClickHouse experience is a plus).
• Hands-on experience with at least one BI tool (QuickSight, Power BI, Tableau or similar).
• Solid understanding of statistics for experiments: significance, power, common pitfalls such as peeking and multiple comparisons.
• Python or R for analysis beyond what SQL covers.
• Ability to explain findings to non-analysts in plain language
• English (B2 or higher).

Would be a plus:

• iGaming experience and familiarity with core metrics: GGR (gross gaming revenue, total bets minus total wins), RTP (return to player, the share of bets paid back as wins), bet volume, retention.
• Experience with data quality checks or building data pipelines.

Your responsibilities will include:

• Own analytics for a set of games or a product area: KPIs, regular reporting, deep dives into player behaviour.
• Design and analyse A/B tests for game mechanics and features, from hypothesis and sample size to the final read-out.
• Build and maintain dashboards in QuickSight / Power BI on top of data in ClickHouse.
• Work with game designers, product managers and data engineers to define metrics and make sure tracking is correct.
• Take part in improving our BI setup, including data models and reporting migration.

We are looking for someone who treats an analytical area as their own, not as a queue of tickets. In practice that means:

• You take a question from a stakeholder and work out what decision it is meant to support, before you write any SQL.
• You notice when a number looks wrong (in your report or someone else’s) and chase it to the root cause instead of passing it on.
• You keep your dashboards and data pipelines alive after release: you know who uses them, check that they still show correct data, and retire what nobody needs.
• You raise problems and trade-offs early, with a proposed way forward, rather than waiting to be asked.
• You finish things: a piece of analysis ends with a clear conclusion and a recommendation, not just a table.

What we offer

• Corporate psychologist;
• Gifts for significant occasions;
• Legal support;
• Flexible working hours;
• Direct access to C-level and opportunity to suggest new business ideas and drive changes.

If you are ready to work in a dynamic team, passionate about the product, technology, and the world of entertainment, we’re waiting for your CV and portfolio to schedule an online/offline meeting and get to know each other better!

Your CV will be carefully reviewed by our TA department, and if it meets the requirements of the position, we will contact you within 3 business days to discuss the possibility of scheduling an interview.

• Write and update call scripts and SMS / messenger texts for different lead segments, including responses to typical client objections.
• Build and optimize multichannel funnels: calls + SMS.
• Plan and run A/B tests, interpret the results, and roll out what works.
• Track and report conversion and retention metrics and make decisions based on the data.
• Explore and implement voice and chat AI bots for conversion and retention.
   

Requirements

• Experience in FX/CFD, including 1–2+ years leading a conversion or retention department (team lead, desk head, Head of).
• Experience writing call scripts and SMS / messenger texts for different lead segments, including objection handling.
• Experience building multichannel funnels (calls + SMS).
• Hands-on experience with A/B testing.
• Experience in iGaming.
   

Nice to Have

• Experience with voice or chat AI bots for conversion and retention.
   

What we offer

• Fully remote work format and flexible working hours.

DOIT Software is looking for an AI/ML Engineer to join the engineering team of a B2B SaaS product company and build machine learning and AI features into its platform.

About the Client

Our client is a SaaS product company working in analyst relations (AR) and B2B influencer relations. Its platform helps technology vendors and B2B companies manage, track, and measure their relationships with industry analysts who influence buyers in the market.

The product combines a specialized CRM with a searchable database of analysts and influencers, analytics and reporting dashboards (share of voice, sentiment, competitive intelligence), and an analyst-facing self-service portal.

About the Role

You will design Python-based models and services, integrate large language models (Anthropic’s Claude), and ship them alongside the client’s software engineering team.

The platform runs on Angular, C# (.NET), SQL Server and MongoDB. You will not be the primary developer on that stack, but you will work in it daily: pulling data from it, exposing your models to it through APIs, and pairing with engineers to get AI features into production.

You will report to the VP of Engineering. This is a full-time, fully remote position that requires at least 3-4 hours of daily overlap with US Eastern Time for standups and pairing.

What You’ll Do

Machine learning and data science

• Design, train, evaluate and deploy ML models for classification, clustering, recommendation, NLP and forecasting use cases.
• Explore, clean and engineer features from product data stored in SQL Server and MongoDB.
• Define metrics, run experiments and report results clearly to engineering and product stakeholders.
• Monitor models in production for drift, accuracy and cost, and retrain as needed.

AI and Claude integration

• Build LLM-powered features using the Claude API: prompt design, tool use, structured outputs and retrieval-augmented generation (RAG).
• Develop evaluation sets and automated tests to measure LLM output quality, accuracy and safety.
• Optimize LLM usage for latency and cost (prompt caching, model selection, batching).
• Use AI coding assistants such as Claude Code to speed up your own development work.

Working with the product engineering team

• Package models and AI logic as Python services and REST APIs that the C# (.NET) backend calls.
• Work with Angular developers to shape how AI features appear and behave in the UI.
• Write efficient SQL Server queries and MongoDB aggregations, and help design schemas for the data that ML features need.
• Take part in code reviews, sprint planning and standups, following the team’s Git, CI/CD and testing practices.
• Document models, data pipelines and APIs so other engineers can support them.

Required Qualifications

• 3–5 years of professional experience in data science, ML engineering or a similar role.
• Bachelor’s degree in Computer Science, Data Science, Statistics, Mathematics or a related field, or equivalent experience.
• Strong Python skills, including pandas, NumPy and scikit-learn.
• Hands-on experience with at least one deep learning framework (PyTorch or TensorFlow).
• Solid understanding of ML fundamentals: supervised and unsupervised learning, feature engineering, model evaluation and avoiding overfitting.
• Practical experience building with LLM APIs, ideally Anthropic Claude: prompt engineering, tool use, RAG and output evaluation.
• Experience building and consuming REST APIs in Python (FastAPI or Flask).
• Working knowledge of SQL (SQL Server preferred) and a NoSQL document database (MongoDB preferred).
• Comfortable with Git, code reviews and Agile/Scrum workflows.
• Clear written and spoken English (Upper-Intermediate or higher) for daily collaboration with a distributed team.
• Proactive written communication: status updates, clear questions and documented decisions.
• Ownership of features from prototype to production, not just notebooks.
• Curiosity about new AI capabilities and the judgment to know when a simpler approach is better.

Nice to Have

• Experience with vector databases or embedding search (e.g., MongoDB Atlas Vector Search, pgvector, Pinecone).
• Familiarity with agent frameworks, the Model Context Protocol (MCP) or the Claude Agent SDK.
• Reading-level familiarity with C# / .NET and Angular / TypeScript, enough to trace how your services are called.
• MLOps experience: Docker, CI/CD pipelines, model versioning (MLflow or similar) and cloud deployment (Azure or AWS).
• Prior work on a multi-tenant B2B SaaS product.
• NLP work on unstructured business text such as documents, emails or research content.
• Understanding of data privacy and security practices for customer data used in AI features.

Recruitment Process

• Own candidate communication through client interviews, offer, negotiation, and hiring decision.
• Track the recruitment funnel and use the data to identify bottlenecks and improve results.
