Job Description
π About the Role
We are looking for an AI Engineer with a strong foundation in backend development and applied AI to join our team.
This role is ideal for someone who has already worked with LLMs, RAG, or AI-powered features, and is looking to grow into building more advanced AI systems such as agent-based architectures and production-grade AI platforms.
You will collaborate with experienced engineers and cross-functional teams to design and build intelligent solutions, while continuing to deepen your expertise in modern AI systems.
π What Youβll Do
- Build and improve AI-powered features using LLMs (e.g. chatbots, copilots, internal tools)
- Contribute to the development of RAG pipelines (document ingestion, embeddings, retrieval)
- Develop backend services and APIs to support AI applications
- Work with vector databases and semantic search systems
- Collaborate on designing scalable AI solutions (with guidance from senior team members)
- Support deployment and monitoring of AI systems in production environments
- Experiment with new AI tools and frameworks to improve development speed and quality
β What Weβre Looking For (Must-have)
- 5+ years of software engineering experience
- Strong backend skills (Python and/or TypeScript)
- Hands-on experience with LLMs (OpenAI, Anthropic, etc.)
- Experience building AI-powered features or applications
- Basic understanding of RAG concepts (embeddings, retrieval, vector search)
- Experience working with APIs and modern backend architectures
- Solid problem-solving skills and willingness to learn
β Nice to Have
- Experience with LangChain, LangGraph, or similar frameworks
- Exposure to AI agents or multi-step workflows
- Experience with vector databases (Pinecone, Weaviate, etc.)
- Familiarity with cloud platforms (AWS, Azure, GCP)
- Experience deploying applications (Docker, CI/CD)
- Interest in prompt engineering or AI evaluation techniques
π§ What This Role Is (and Is Not)
This role is:
β A strong engineering role with exposure to AI systems
β A growth path toward advanced AI architectures
β A hands-on position building real products
This role is not:
β A pure research or data science position
β A senior AI architect role (yet)
β A prompt-only or no-code AI role
