Job summary

FastTek Global is seeking an experienced AI software engineer to design and deploy intelligent programs, cognitive applications and data-driven automation. You will build production ML/AI systems, orchestrate multi-agent workflows and translate complex requirements into scalable solutions.

The role emphasizes cutting-edge AI techniques, including LLMs, RAG pipelines, and cloud deployments, with security, observability and cost optimization at the core.

Qualifications

• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related field (or equivalent practical experience).
• 3+ years building production software systems, including 1-2+ years on ML/AI or LLM-based applications.
• Strong Python proficiency, including async/concurrent programming, and experience with backend frameworks (FastAPI, Flask).
• Hands-on experience with agent orchestration frameworks — LangGraph, CrewAI, LlamaIndex, or equivalent.
• Practical experience building RAG pipelines: vector databases (pgvector, Pinecone, Weaviate, or Qdrant), embeddings, chunking strategies, and retrieval evaluation.
• Cloud deployment experience, ideally Google Cloud Platform (BigQuery, Cloud Run/GKE, Vertex AI, Pub/Sub) or equivalent AWS/Azure services.
• Strong SQL skills and experience with cloud data warehouses. Containerization and CI/CD experience (Docker, Kubernetes, GitHub Actions/Cloud Build).
• Experience building evaluation and observability pipelines for LLM/agent systems — offline eval sets, LLM-as-judge scoring, and tracing tools (LangSmith, Langfuse, OpenTelemetry, or equivalent) to track task success, latency, and cost.
• Understanding of LLM safety practices: guardrails, output validation, prompt-injection defense, and safe execution of AI-generated code/SQL (sandboxing, least privilege). Solid software engineering fundamentals: API design, testing, version control, security best practices.

Responsibilities

• Understand business requirements and develop AI algorithms, models and programs to solve complex problems, generate recommendations, extract patterns, make predictions, interpret sensor data (images, sound), orchestrate automation and enable self-service capabilities
• Perform large-scale experimentation and develop data driven applications that translate data into actionable intelligence
• Drive innovative applications of Artificial Intelligence tools and techniques such as deep learning, generative AI, natural language processing, image processing, cognitive automation, intelligent process automation, reinforcement learning, virtual assistants and specialized programming
• Research and optimize AI technologies to enhance efficiency and accuracy of data analysis and create more efficient automation
