Senior Systems Architect (Pega)

What success looks like in this role:

An onshore Pega Senior System Architect (SSA) is the senior hands‑on technical lead who designs, builds, and optimises Pega applications while mentoring the team and ensuring compliance with enterprise and government standards.

• Translate business requirements and blueprints into robust case types, data models, flows, and rules that follow Pega guardrails and patterns.

• Own complex configurations beyond low‑code (data pages, integrations, queues, background processing, security) and ensure they are scalable and maintainable.

• Implement and refine reusable components and frameworks so multiple journeys or channels can leverage a common design.

• Provide day‑to‑day technical leadership to LSAs/SSAs/devs, reviewing designs and rules to uphold best practices, performance, and security.

• Debug and tune the application, addressing performance bottlenecks, memory issues, and inefficient designs using Pega’s diagnostic tools.

• Enforce standards for branching, pipelines, code review, and guardrail compliance to keep the implementation “upgrade‑friendly.”

• Design and implement integrations (REST/SOAP, queues, messaging, SSO) and ensure they align with enterprise integration patterns.

• Configure and validate access control (RBAC, ABAC) and security settings to comply with government and organisational security frameworks.

• Work with architects and infrastructure teams on NFRs (availability, response times, logging, DR, monitoring) and support SLA and service‑credit obligations.

• Work on‑site/locally with business, LSAs, security and operations teams to resolve design decisions quickly and support agile ceremonies (refinement, planning, demos).

• Explain technical options and trade‑offs in plain language to business and client stakeholders, influencing solution choices while protecting technical integrity.

• Mentor junior system architects and developers, lifting team capability and reducing dependency on external SMEs over time.

• Support testing, deployment and early life support (hypercare), including triaging production issues, root‑cause analysis, and implementing fixes.

• Contribute to roadmap and continuous improvement, suggesting refactoring, reuse opportunities, and incremental enhancements as the platform matures.

You will be successful in this role if you have:

• Pega Certified Senior System Architect (CSSA / PCSSA), with Pega CSA as prerequisite.

• Several years of hands‑on Pega delivery experience (typically 3–5+ years), designing and building enterprise Pega applications across case management, data/integration, performance, and security areas.

• Strong command of Pega application architecture: case lifecycle design, data modelling, integrations (REST/SOAP, queues), security and access control, and performance tuning.

• Proven ability to design for reusability across multiple journeys or business areas and to debug complex issues using Pega’s diagnostic and monitoring tools.

• Experience delivering Pega solutions in government or regulated environments, aligning implementations to policies, security standards, accessibility (e.g., WCAG 2.1 AA), and strict SLAs.

• Familiarity with public‑sector complaint or case management style workloads (high volume, sensitive data, strong auditability and reporting requirements).

• Strong Agile/Scrum or Pega Express experience, working as a senior member of a multi‑disciplinary squad and collaborating with LSAs, business architects, testers and DevOps teams.

• Excellent communication and stakeholder skills: able to explain technical options clearly, mentor junior team members, and work directly with client SMEs and technical leads on‑shore.
