Gen AI engineer – Energy Trading
Our Energy Trading client is looking to build out an AI team to work on a number of projects across their business. They are seeking an engineer who can take an idea for an intelligent agent and turn it into a reliable, production-ready system.
What You’ll Be Working O
* nDesigning and refining autonomous AI agent
s using modern orchestration frameworks (e.g., LangGraph, Semantic Kernel) and a mix of cloud-hosted and open-source language models
* .Developing complete agent workflow
s, from event triggers to model endpoints to user-facing integrations. Expect to work with systems like n8n, Ray Serve, vector stores (pgvector, cloud search), and messaging surfaces such as Teams or similar platforms
* .Building and operating cloud infrastructur
e using container orchestration and infrastructure-as-code tools (e.g., Kubernetes, Terraform/Bicep, CI/CD pipelines)
* .Implementing secure-by-default system
s, including identity management, secrets handling, and automated access controls
* .Monitoring and optimizing performanc
e, using observability tooling to track cost, latency, throughput, and agent quality
* .Collaborating directly with domain specialist
s to iterate rapidly—turning sketches into working prototypes in weeks, not months
.
