The Role

Senior Python AI Engineer

Design and develop backend systems and APIs for AI-powered applications. You will play a key role in building scalable backend systems and APIs, collaborating closely with cross-functional teams to shape the future of data-driven products across various platforms.

What we are looking for

  • Strong proficiency in Python (5+ years), including modern frameworks (FastAPI, Flask, or Django).
  • Deep learning frameworks (PyTorch, TensorFlow) for custom modeling beyond LLM APIs.
  • Experience with large language models (LLMs) such as GPT, Gemini, LLaMA, or similar.
  • Experience with prototyping tools: Streamlit, Gradio.
  • Solid experience designing RESTful APIs and microservice architectures.
  • Experience with version control (Git) and CI/CD workflows.
  • Hands‑on experience with containerization (Docker, ideally Kubernetes).
  • Familiarity with cloud platforms (AWS, Azure, or GCP) is a plus.
  • Understanding of security best practices for handling sensitive data.
  • Strong problem‑solving skills to address complex challenges and performance bottlenecks.
  • Excellent technical communication skills to collaborate effectively across teams and explain technical concepts to non‑technical stakeholders.
  • Ability to work independently while aligning with broader team goals.
  • Intermediate‑advanced English level.

AI/ML & LLM Ecosystem

  • Experience with vector databases (Pinecone, Weaviate, Milvus, Chroma, FAISS).
  • Hands‑on with LLMs & APIs: OpenAI (GPT‑5/5‑mini), Anthropic Claude, Google Gemini, Meta Llama, Mistral.
  • Familiarity with AWS Bedrock for accessing and deploying foundation models.
  • Prompt engineering and structured output design (JSON mode, function calling).
  • Model fine‑tuning (LoRA, QLoRA) and evaluation frameworks (DeepEval, Ragas).

Responsibilities

  • Design and develop backend systems and APIs for AI-powered applications.
  • Build and optimize LLM‑based workflows, including chatbots, copilots, and automation tools.
  • Implement RAG architectures using vector databases and document pipelines.
  • Integrate and orchestrate cloud‑hosted foundation models (AWS Bedrock, OpenAI, Anthropic, Google Gemini, Meta Llama, Mistral).
  • Collaborate cross‑functionally with data scientists, product managers, and frontend developers to deliver end‑to‑end AI products.
  • Ensure performance, scalability, and cost optimization of AI solutions in production environments.
  • Monitor, evaluate, and continuously improve deployed AI systems.

What we offer

  • Guaranteed on‑time monthly payments with flexible withdrawal options.
  • Predictable 8‑hour working days, enabling a harmonious work‑life balance.
  • Up to 24 flex days off per year for full‑time positions found through Proxify, without losing pay.
