SENIOR STAFF SOFTWARE ENGINEER Location: Americas (preferably EST) — Remote Employment Type: Full-Time Department: Engineering ABOUT YOUR ROLE We are seeking a Senior Staff Software Engineer to lead the architecture and evolution of the core systems that power Juniper Square — the distributed services, cloud infrastructure, and developer platform on which every product, workflow, and AI capability is built. You will define the vision, architecture, operating model, and execution roadmap required to evolve from team-by-team infrastructure decisions to a cohesive, paved-road platform that enables every engineering team to ship reliable, secure, and performant software at speed. This role anchors a strategic priority for our GPX line of business: taking Juniper Square upmarket to serve the largest private equity institutions in the world — firms managing $100B+ in AUM. Serving these PE titans demands a step-change in everything our systems do: order of magnitude increase in data and traffic volumes; enterprise-grade security, and integration expectations. You will architect the systems foundation that makes this scalable. This is a deeply hands-on leadership role for a technical expert who leads by building: you will actively design systems, prototype solutions, write and review code, and guide teams through their most complex technical challenges. Your mandate spans the full systems estate. You will modernize our service architecture and cloud foundation, define architecture across compute, networking, service communication, multi-tenancy, and observability, and build the systems substrate — including the infrastructure powering JunieAI and agentic workloads — on which teams across the business build and operate software. Throughout, you will hold our production systems to the availability, latency, security, and cost standards expected of a platform administering $300B+ in private markets assets. You will work closely with engineering leadership, product teams,
