Role Overview
We're looking for a Junior AI Application Engineer to join our GenAI delivery team and help build production LLM/SLM applications — including for air-gapped and on-prem environments. You'll work on well-scoped pieces of larger features under the guidance of a senior Application Engineer or Technical Program Lead, with plenty of room to grow into full feature ownership.
Key Responsibilities
● Build defined components of RAG pipelines, agents, and LLM/SLM-backed features from specs handed off by senior engineers.
● Write and test Python code — API endpoints, data pipelines, and integration glue between LLM components and internal systems.
● Assist with fine-tuning, quantizing, and evaluating SLMs under supervision; run benchmarks and document results.
● Help set up and maintain vector store integrations (FAISS, Milvus, Weaviate, Qdrant) and local inference serving (vLLM, Ollama).
● Containerize small services (Docker) and support deployment to cloud/on-prem targets alongside senior team members.
● Keep JIRA stories updated, raise blockers early,



and demo completed work in sprint reviews.
● Use Claude Code / AI coding agents as your default way of writing code — learn to write clear specs/prompts and to carefully review and test what the agent produces before it ships.
Required Skills & Experience
● 1–3 years of qualified software engineering experience (internships count toward this).
● Solid Python fundamentals; comfortable reading and debugging someone else's code.
● Some exposure to LLMs/GenAI — coursework, personal projects, hackathons, or prior work experience with LangChain/LlamaIndex, OpenAI/Anthropic APIs, or similar.
● Basic understanding of REST APIs, git, and working in a codebase with others.
● Curious and comfortable using AI coding tools (Claude Code or similar) as part of daily work, with a habit of reviewing generated code rather than accepting it blindly.
● Willingness to learn Docker, cloud basics (AWS/Azure/GCP), and vector database
