Jobs at Djinni

N-iX is looking for an experienced Senior Java Engineer who goes beyond standard CRUD APIs and lives in the world of information retrieval.

Our customer is a Fortune 500 company. As a leading business-to-business organization, more than 3.2 million customers rely on its products in categories such as safety, material handling, and metalworking, along with services like inventory management and technical support. ​

In this role, you will act as the bridge between our core Java application architecture and our specialized search infrastructure. You will be responsible for the entire search lifecycle: from designing how data is ingested and indexed, to building the Java APIs that query that data, and crucially, tuning the relevancy algorithms that ensure our users find exactly what they are looking for, instantly. 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

Requirements

At Sempico Solutions, we're looking for a hands-on AI Engineer (Middle+/Senior) who doesn't just experiment with models — but builds AI systems that work reliably in production and deliver measurable impact on real business processes.

You are someone who thinks in terms of quality metrics, not "generally good." You bring structure to data and logic, take ownership of AI outcomes, and know how to move from idea to stable production without losing quality along the way.

Our ideal candidate has:

• 3+ years of experience in AI/ML in production environments (not pet projects).
• Confident Python skills — your primary working language.
• Hands-on experience with LLM APIs in production (OpenAI, Anthropic, or open-source models).
• Systematic approach to prompt engineering: versioning, A/B testing, quality control.
• End-to-end RAG architecture experience: chunking, embeddings, retrieval, reranking, vector databases (Pinecone, Qdrant, Weaviate, or pgvector).
• Experience building AI evaluation frameworks — automated quality tests for AI responses.
• Knowledge of privacy and GDPR considerations when working with client data.
• REST API integration experience and async I/O work.
• Basic DevOps skills: Docker, monitoring, logging.
• Fluent Ukrainian (C1 or native) and English at B2 Upper Intermediate level or higher (both spoken and written).
• Understanding of prompt injection risks and data leak prevention.

Nice to have:

• Experience integrating messengers: Telegram Bot API, WhatsApp Business API, Microsoft Teams Graph API.
• Experience with support platforms: HelpCrunch, Intercom, or Zendesk API.
• Familiarity with LangChain, LlamaIndex, or Haystack.
• Classical ML background: scikit-learn, PyTorch, or TensorFlow.
• Experience in CPaaS / SMS industry.
• Automation tools: n8n, Zapier, or Make — for rapid flow prototyping.
• PHP reading ability (to navigate the existing product codebase).
• Experience building AI systems from scratch in a startup environment.

What You'll Do

• Build and maintain a unified client inbox — bringing all communication channels (Telegram, WhatsApp, Teams, HelpCrunch, email) into one structured place.
• Launch and continuously develop the AI Support mechanism across all client chat channels.
• Form and maintain the knowledge base that powers AI responses.
• Monitor AI response quality in production: track metrics, run A/B tests, proactively detect degradation.
• Control and optimize AI call costs — you know what your solution costs per month in tokens.
• Integrate AI into other business processes: sales, analytics, and internal tooling.
• Document AI architecture, flow logic, and known limitations clearly — for both technical and non-technical colleagues.

• Contributing to implementation tooling, documentation, and repeatable deployment processes
• Troubleshooting and resolving issues during and after deployment
• Occasionally participating in client calls to gather requirements or provide technical guidance

What we're looking for

• Strong proficiency in Vue.js, Node.js, and TypeScript
• PostgreSQL/similar RDBMS and general data modeling knowledge
• Familiarity with cloud platforms (AWS, Azure, or GCP), multi-cloud exposure is valuable
• Clear communication skills - comfortable explaining technical concepts to non-technical stakeholders
• Ability to work independently and manage multiple implementation workstreams
• 5+ years of software engineering experience
