Full Stack Aws Python Developer Jobs in Wisconsin

Portfolio BI’s flagship products and services, PBI Axiom, PBI Vector, and PBI Stratus, enable alternative asset managers to address their data challenges in analytics, workflow, governance, and security.

We are hiring a Full Stack Developer to design, build, and support applications and services that power credit, private credit, structured products, and CLO businesses.

You will work alongside the CIO and senior members of Business Technology to contribute to the modernization of the analytics and reporting platform - moving legacy applications to a responsive, cloud-aware architecture, replacing ad-hoc spreadsheets with auditable services, and building the data and tooling layer that supports the firm’s various lines of business.

You will also be expected to use AI coding assistants as a daily part of your workflow.
