About the role

We file this job under AI Engineer, by the work the posting describes.

AI engineers build products on top of AI models that already exist, most often large language models: they connect a model to a company's data and tools and ship the assistants, agents and search features people use.

Postings ask for strong Python or TypeScript, experience with model APIs, retrieval and agent frameworks, and ways to test whether the model's answers are good enough.

An ML engineer trains and serves models; an AI engineer usually starts from a model someone else trained and builds the product around it, though titles often mix the two.

  • Bash scripts for automation, data handling, and container interaction.
  • LLMs Architecture understanding proven by project portfolio.
  • Architecting multi-step, stateful agentic graphs using LangGraph or Google ADK.
  • Hands-on experience optimizing LLM pipelines programmatically using DSPy.
  • Practical knowledge of deploying and running high-throughput open-weight models on GPU infrastructure using runtimes such as vLLM (experience with CUDA and fine-tuning is a strong plus).
  • Hands-on familiarity with automated build, test, and release pipelines (Jenkins).
  • Experience setting up tracing, drift detection, and automated evaluations for generative workflows using tools like Phoenix Arize.
  • Dedication to shipping stable, secure code into flagship banking infrastructure where compliance, auditability, and data security are non-negotiable.
  • General Stack: Google ADK, LangGraph, DSPy, vLLM, FastAPI, Python, Pytest. Arize Phoenix. Kubernetes, Jenkins, GPUs.
 
Responsibilities:
 
  • Design and develop LLM-based agentic solutions to automate complex business processes.
