## Description

PEGA SSA - Constellation Focus/Pega Platform '26 - 2 months - Start ASAP

We are seeking a high-calibre Pega Senior System Architect (SSA) with deep expertise in Pega Constellation to lead a critical Proof of Concept (POC). In this role, you will be the core technical driver responsible for validating architecture, building high-performance reactive UI applications, and demonstrating the business value of Pega's modern design system. You will bridge the gap between Legacy Pega architectures and modern, API-driven Constellation applications to set the technical blueprint for our future enterprise solutions.

Core Responsibilities

 * POC Execution: Rapidly design, build, and deliver a high-visibility Proof of Concept (POC) utilizing the Pega Constellation architecture.

 * Architecture & UI Design: Leverage Constellation's view-based architecture, orchestration engine, and design system to build clean, low-code, and highly performant user interfaces.

 * API & Integration: Configure and optimize DX APIs (v2) to ensure seamless communication between the Pega Back End and the Constellation UI layer.

 * Technical Leadership: Guide the team on Constellation best practices, guardrails, and limitations, steering them away from traditional section-based UI anti-patterns.

 * Performance Tuning: Troubleshoot and optimize application performance, focusing on payload sizes, state management, and rendering speeds inherent to Constellation.

 * Stakeholder Collaboration: Present POC outcomes, architectural advantages, and feasibility metrics to technical and business stakeholders.
