Principal Software Engineer
Arcfield
We are seeking a highly skilled Senior Full‑Stack Software Engineer to join our team to build and scale our next‑gen Intelligent Model‑Based Systems Engineering (iMBSE) platform. In this role, you will be at the forefront of integrating state‑of‑the‑art Artificial Intelligence into enterprise engineering workflows. You will design and develop robust, cleanly separated system layers—from React‑based user interfaces to scalable backend APIs powered by Python and Rust. A core focus of this position will be designing and implementing Agentic AI solutions, Custom Workflows, and RAG (Retrieval‑Augmented Generation) services utilizing industry‑leading LLMs like GPT‑4o and Meta Llama 3. You will work within a mature, automated DevSecOps environment, ensuring that code is secure, tested, and seamlessly deployed to Kubernetes clusters across AWS and Azure environments.
Design, build, and maintain full‑stack features across the iMBSE platform, including user‑facing web applications, orchestration APIs, and backend microservices.
Develop and deploy agentic AI solutions, such as LLM‑driven workflows, RAG services, and autonomous chat agents.
Ensure compliance with DevSecOps best practices, leveraging CI/CD pipelines and automated testing, security scanning, and cloud‑native tooling.
