Jobs at Djinni

We’re looking for a Front-End Engineer to join our team. 

Work Location: Poland (Krakow), Slovakia (Kosice) or Czechia (Prague). 

Hybrid: 2+ days per week in the office, the rest remote.

The Mission

We are building a complex, real-time ecosystem for micromobility and logistics systems sim—where split-second logistics meet seamless user experiences. We need a Front-End powerhouse to lead the development of our Customer Mobile Web App and our high-utility Internal Admin Panels.

You’ll be the bridge between the sleek, high-performance interface our users see and the robust, scalable Python services that power the logic.

• Mobile-First Frontend: Architect and scale our React-based mobile web application, ensuring 60fps performance and offline-first capabilities.
• Operational Control Centers: Build dense, data-heavy Admin Panels that allow our operations team to monitor real-time logistics, manage users, and handle complex dispatching.
• Scalable Backend: Design and maintain performant APIs using Python (FastAPI/Django) to handle high-concurrency event streams.
• End-to-End Ownership: From database schema design to CSS transitions, you’ll own the entire feature lifecycle.

Who You Are

• The Architect: You don't just "write code"; you design systems. You understand how a change in a Python microservice ripples out to the React frontend.
• UX Enthusiast: You understand that an Admin Panel requires different UX "muscle" (efficiency and density) than a mobile app (simplicity and speed).
• Problem Solver: You’ve dealt with the "hard stuff"—real-time GPS tracking, race conditions in booking logic, or complex state management.
• Pragmatist: You balance the need for clean, tested code with the reality of shipping features in a fast-paced environment.

Will be a plus Led transformation of standalone product into scalable SaaS platform.

Let’s Start With a Hello

We’re hiring a Middle Affiliate Manager to join our team and help scale performance across key Asian markets. If you already know how affiliate partnerships work in iGaming/betting and you’re ready to grow fast in a team that builds, tests, and scales — you’ll feel at home here.

Who We Are

We’re a fast-growing iGaming company with a betting/gambling product launched ~2.5 years ago. Since day one, we’ve been building with one goal: create a product that players love — and a performance engine that scales.

We’re actively expanding across Europe, Africa, and Asia, and affiliates are one of our core growth channels. Our culture is simple: ownership, speed, transparency, and teamwork — with enough healthy competition to keep things exciting.

What You’ll Be Doing

• Support and grow affiliate performance across Bangladesh, Nepal, Pakistan, Sri Lanka, and the Philippines (with guidance from a Senior/Lead).
• Manage a portfolio of existing partners: onboarding, activation, daily communication, and performance follow-ups.
• Help source and recruit new affiliates: outreach, introductions, deal setup, and ongoing relationship building.
• Assist with commercial work: prepare terms, track deals (CPA / RevShare / Hybrid), and ensure clean execution.
• Track performance daily: registrations, FTD, conversion, retention/LTV, ROI — and turn insights into actions.
• Monitor traffic quality and flag risks early (fraud signals, incentivized traffic, compliance concerns).
• Coordinate with CRM/product/analytics to improve funnels and increase partner efficiency.
• Maintain structured reporting: weekly updates, partner summaries, pipeline tracking, next-step plans.

What Makes You a Great Fit

• You have 1–3 years in iGaming/betting affiliates (or strong affiliate experience in a closely related performance environment).
• You understand the basics of affiliate ops: partner management, tracking links, funnels, and key KPIs (FTD, CR, retention, ROI).
• You’re comfortable communicating with partners and building long-term working relationships.
• You’re organized and proactive: you follow up, keep pipelines clean, and don’t drop tasks mid-flight.
• You’re data-aware: you can read performance reports, spot patterns, and suggest optimizations.
• You care about traffic quality and can follow compliance rules without slowing the business down.
• English is a must (regional languages are a plus); experience with affiliate platforms/tracking tools is a plus.

What’s In It for You

• A competitive salary plus performance bonuses that reward your hard work.
• Flexibility in where and how you work.
• A multicultural team that feels like friends as much as colleagues.
• Opportunities to grow, take on new challenges, and shape your own path.

Let’s Wrap It Up

If you want to grow in affiliates and help scale Asia GEOs in a fast-moving iGaming team — let’s talk. Send your CV and a short note on your affiliate experience, strongest GEOs (if any), and partner types you’ve worked with.

The ideal candidate has deep roots in the Apache Solr ecosystem but is also ready to embrace modern cloud-native search via AWS OpenSearch. Whether you are maintaining critical legacy Solr clusters or architecting new solutions on AWS, your goal is to make data findable, fast, and relevant.

Technology stack: Java/Spring Boot, Apache Solr (Legacy/Core), AWS OpenSearch (Modern/Growth), SQL DB, Kafka 

Responsibilities:

• Design, develop, and maintain high-performance backend Java services (primarily Spring Boot) that integrate with search engines.
• Build complex search features for the frontend, including faceted navigation (filtering), multi-tenant searching, real-time autocomplete/typeahead, and spell-checking suggestions.
• Utilize Java client libraries (such as Solr or AWS SDKs) to construct efficient, programmatic queries.
• Take ownership of the search schema design, deciding how complex data structures should be analyzed, tokenized, and stored for optimal retrieval.
• Build robust ETL pipelines in Java (potentially using Kafka or other messaging systems) to synchronize data from primary SQL databases into the search indices in near real-time.
• Configure analyzers, stemmers, and tokenizers to handle nuances in human language.
• Diagnose slow queries, analyze search logs, and optimize both Java application code and search engine configurations for low-latency performance.
• Maintain and optimize existing on-premise or cloud-hosted Apache Solr installations.
• Play a key role in designing hybrid strategies or migration paths from legacy Solr systems to managed AWS OpenSearch environments.

Requirements: 

• 5+ years of professional experience in backend software development using modern Java (Java 8+, Spring Boot ecosystem).
• Strong, demonstrable experience with Search Technologies. This means either:
  • Hands-on production experience configuring, managing, and developing against Apache Solr (understanding schema.xml, solrconfig.xml, Zookeeper integration).
  • OR deep foundational knowledge of Lucene-based search concepts (inverted indices, analysis chains, TF-IDF/BM25 scoring logic) with the ability to quickly apply that to Solr.
• Hands-on experience with AWS OpenSearch (or Elasticsearch) in a managed cloud environment.
• Experience with data modeling in relational databases (PostgreSQL, MySQL, Oracle).
• Strong understanding of RESTful API design principles.
• Preferred Qualifications:
  • Experience architecting zero-downtime migrations from self-hosted Solr to managed cloud search services.
  • Experience with event-driven architecture and streaming tools like Apache Kafka for real-time indexing.
  • Familiarity with containerization (Docker, Kubernetes) and CI/CD pipelines like Jenkins or GitLab CI.

We offer*:

• Flexible working format - remote, office-based or flexible
• A competitive salary and good compensation package
• Personalized career growth
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
• Active tech communities with regular knowledge sharing
• Education reimbursement
• Memorable anniversary presents
• Corporate events and team buildings
• Other location-specific benefits
