Jobs at Djinni

Product Manager / Product Owner

📍 Remote 
💼 Full-time
 

About Us

We’re HappyCrown, a small but growing team building gaming marketplaces. No gambling, no casinos — just platforms where gamers can buy, sell, and trade in-game items safely and easily.

Right now, we run Bloxcart.com (a Roblox marketplace that’s already making great revenue) and we’re about to launch SkinsHero, a trading platform for CS:GO and Rust skins. Things are going well, but we need someone to help us restructure, build a strong team, and level up our operations.
 

What We’re Looking For

We need a Product Manager/Product Owner who isn’t just looking for a “job” but wants to step up and take charge. There’s a lot to do, and you’ll have a major role in shaping how we grow.

You’ll:

• Create and own the product roadmap — bring clarity to our plans and set priorities.
• Take over backlog and project management so everything is organized and on track.
• Oversee team performance and ensure accountability.
• Restructure and rebuild the team: hire the right people for marketing (Google Ads, SEO), design, development, and more.
• Drive UI/UX improvements, marketing strategies, and product quality.
• Work closely with leadership to make sure the business is running smoothly.
   

This role is about leadership and building processes as much as it is about product. If you’re good at hiring, organizing chaos, and getting results, you’ll thrive here.

Gaming knowledge (Roblox, CS:GO, Rust) is a plus but not required. IT/technical knowledge is also helpful but this is not a developer role.
 

What We Offer

• Competitive salary
• Full ownership of your work (we don’t micromanage)
• $2,000 home office budget to set yourself up
• 20 days paid vacation (and room for more)
• Optional visa sponsorship & relocation to Bristol/Bath, UK (hybrid/onsite if it works long-term)
• A clear path to bigger roles as we grow
• A tight-knit, easygoing team that avoids corporate BS
• A chance to work on gaming platforms you’d actually use
   

Why This is Exciting

We’re at a pivotal stage:

• Bloxcart is making solid revenue and needs polish.
• SkinsHero is about to launch with big potential.
• We want to restructure, hire great talent, and scale fast.

This is a chance to join early, shape the company, and build something gamers actually love — without getting lost in a corporate mess.

Knowledge of Ukrainian text sources and data sets, or experience with multilingual data processing, can be an advantage given the project’s focus.
Understanding of FineWeb2 or a similar processing pipeline approach.
- Data Pipeline Expertise: Hands-on experience designing ETL/ELT processes, including extracting data from various sources, using transformation tools, and loading into storage systems. Proficiency with orchestration frameworks like Apache Airflow for scheduling workflows. Familiarity with building pipelines for unstructured data (text, logs) as well as structured data.
- Programming & Scripting: Strong programming skills in Python for data manipulation and pipeline development. Experience with NLP packages (spaCy, NLTK, langdetect, fasttext, etc.). Experience with SQL for querying and transforming data in relational databases. Knowledge of Bash or other scripting for automation tasks. Writing clean, maintainable code and using version control (Git) for collaborative development.
- Databases & Storage: Experience working with relational databases (e.g., PostgreSQL, MySQL), including schema design and query optimization. Familiarity with NoSQL or document stores (e.g., MongoDB) and big data technologies (HDFS, Hive, Spark) for large-scale data is a plus. Understanding of or experience with vector databases (e.g., Pinecone, FAISS) is beneficial, as the NLP applications may require embedding storage and fast similarity search.
- Cloud Infrastructure: Practical experience with cloud platforms (AWS, GCP, or Azure) for data storage and processing. Ability to set up services such as S3/Cloud Storage, data warehouses (e.g., BigQuery, Redshift), and use cloud-based ETL tools or serverless functions. Understanding of infrastructure-as-code (Terraform, CloudFormation) to manage resources is a plus.
- Data Quality & Monitoring: Knowledge of data quality assurance practices. Experience implementing monitoring for data pipelines (logs, alerts) and using CI/CD tools to automate pipeline deployment and testing. An analytical mindset to troubleshoot data discrepancies and optimize performance bottlenecks.
- Collaboration & Domain Knowledge: Ability to work closely with data scientists and understand the requirements of machine learning projects. Basic understanding of NLP concepts and the data needs for training language models, so you can anticipate and accommodate the specific forms of text data and preprocessing they require. Good communication skills to document data workflows and to coordinate with team members across different functions.

Responsibilities:
- Design, develop, and maintain ETL/ELT pipelines for gathering, transforming, and storing large volumes of text data and related information.
- Ensure pipelines are efficient and can handle data from diverse sources (e.g., web crawls, public datasets, internal databases) while maintaining data integrity.
- Implement web scraping and data collection services to automate the ingestion of text and linguistic data from the web and other external sources. This includes writing crawlers or using APIs to continuously collect data relevant to the language modeling efforts.
- Implementation of NLP/LLM-specific data processing: cleaning and normalization of text, like filtering of toxic content, de-duplication, de-noising, detection, and deletion of personal data.
- Formation of specific SFT/RLHF datasets from existing data, including data augmentation/labeling with LLM as teacher.
- Set up and manage cloud-based data infrastructure for the project. Configure and maintain data storage solutions (data lakes, warehouses) and processing frameworks (e.g., distributed compute on AWS/GCP/Azure) that can scale with growing data needs.
- Automate data processing workflows and ensure their scalability and reliability.
- Use workflow orchestration tools like Apache Airflow to schedule and monitor data pipelines, enabling continuous and repeatable model training and evaluation cycles.
- Maintain and optimize analytical databases and data access layers for both ad-hoc analysis and model training needs.
- Work with relational databases (e.g., PostgreSQL) and other storage systems to ensure fast query performance and well-structured data schemas.
- Collaborate with Data Scientists and NLP Engineers to build data features and datasets for machine learning models.
- Provide data subsets, aggregations, or preprocessing as needed for tasks such as language model training, embedding generation, and evaluation.
- Implement data quality checks, monitoring, and alerting. Develop scripts or use tools to validate data completeness and correctness (e.g., ensuring no critical data gaps or anomalies in the text corpora), and promptly address any pipeline failures or data issues. Implement data version control.
- Manage data security, access, and compliance.
- Control permissions to datasets and ensure adherence to data privacy policies and security standards, especially when dealing with user data or proprietary text sources.
