Description

Portfolio BI's flagship platforms - PBI Axiom, PBI Vector, and PBI Stratus - empower alternative asset managers to solve complex data challenges across analytics, workflow, governance, and security. Our Stratus practice delivers fully managed IT and cybersecurity services to hedge funds, private equity firms, and other financial services clients who demand enterprise-grade reliability from a team that understands their business.

We are seeking a seasoned Sr. System Engineer - Onsite to serve as the primary technical presence at a high-profile financial services client.

You will bring deep cloud and infrastructure expertise, a strong automation mindset, and the client-facing maturity to translate technical complexity into business outcomes. You will serve as the escalation anchor for all Level 1 and Level 2 issues, partner with our engineering teams on complex initiatives, and ensure the client's environment evolves alongside their business.
