Description
About the Company
BotsCrew is an AI-focused software company with over 10 years of experience building custom AI solutions for businesses worldwide. Starting as a chatbot development company, we have evolved into a team specializing in Generative AI, AI Agents, and intelligent automation solutions.
We help companies across healthcare, fintech, e-commerce, HR tech, and other industries integrate AI into real products and business processes. Our team works with modern AI technologies, including OpenAI, Anthropic, Gemini, LangChain, RAG systems, and AI workflow automation.
About the Role
As a Full Stack Developer at BotsCrew, you’ll build and scale AI-powered features for real client products — with Java as your primary backend language and React/Next.js on the frontend. This is a hands-on engineering role where you’ll own features from design through delivery, working on systems that combine solid backend architecture with applied AI capabilities.
We focus on building robust, production-grade solutions that integrate LLMs, intelligent pipelines, and automation into client workflows. We’re looking for engineers who are strong in Java, comfortable across the full-stack, and have real experience shipping AI-driven functionality — not just experimenting with it.
Requirements
Must Have:
2+ years of commercial experience in backend or full-stack development
Strong hands-on experience with Java (priority) — Node.js experience is a plus
Experience with modern frontend frameworks: React.js or Next.js
Solid understanding of RESTful API design and integration
Experience with Docker for local development and deployment
Familiarity with CI/CD pipelines (e.g., GitHub Actions, GitLab CI)
Real, commercial or project-based experience with AI/LLM technologies: working with LLM APIs (OpenAI, Claude, Gemini), prompt engineering techniques, embeddings and vector databases, RAG pipelines or AI-driven product features
English B2 or higher
Nice to Have:
Experience with the Spring Framework
Hands-on experience building AI assistants or autonomous agents
Experience with vector databases (e.g., Pinecone, Weaviate, Qdrant)
Familiarity with agentic frameworks (e.g., LangChain, LlamaIndex)
Experience with Python for AI/ML-related tasks
Contributions to open source or personal AI projects
Responsibilities:
Build and maintain backend APIs primarily in Java, with Node.js as needed
Design and improve frontend interfaces using React.js and Next.js
Develop and enhance
LLM-based
features — prompt pipelines, embeddings, vector storage, and AI-driven functionality
Write clean, testable, and well-documented code with long-term maintainability in mind
Contribute to system architecture and scalable solution design
Collaborate with clients and stakeholders to gather requirements and deliver measurable value
Participate in agile ceremonies — stand-ups, retrospectives, and sprint planning
We Offer:
20 working days of paid vacation
5 days of paid sick leave
Equipment provided
Access to Regus coworking spaces when needed
FOP (private entrepreneur) accounting and support services
ChatGPT for Business provides access to support productivity and AI experimentation
Personal Development Plan (PDP) creation and guidance from mentors
A talented team and a culture that blends innovation, speed, and real business impact
