Remote

Global IT company who specialise in software for the design and engineering domain is looking to hire a Senior Solution Architect for a remote contract role.

Top 3 Experience "Must Haves":

1. Proven experience designing and building systems, solution, platform, or enterprise architecture within the AWS ecosystem.
2. Strong knowledge of domain-driven design, API architecture, relational and event-driven data models.
3. Experience designing, building, or supporting integrations with enterprise HR, finance, or workforce planning systems, such as Workday HCM, Workday Adaptive Planning, or similar platforms.

Responsibilities

• Lead the design and delivery of a secure orchestration platform for sensitive workforce transformation workflows, partnering with HR and adjacent teams.
• Define the end-to-end target architecture spanning frontend applications, backend services, databases, workflow-control services, identity and access, audit, integration adapters, reporting, export, and deployment.
• Design the reusable workflow foundation for role permissions, stage gates, approval routing, scenario/version management, change ledger, validation, reporting, exports, and reconciliation.
• Define data-isolation and access-control patterns so multiple Business Transformation products can reuse shared technical components while maintaining separate security rules, data models, workflows, user groups, and operating processes.
• Establish nonfunctional requirements for scale, availability, recoverability, observability, performance, maintainability, disaster recovery, and support.
• Lead technical design reviews, architectural decisions, risk management, engineering standards, and solution documentation.
• Provide active technical direction to the Full-Stack Engineers and implementation team, ensuring build decisions align with the approved architecture, security model, and platform roadmap.
• Contribute hands-on to technical design, prototypes, implementation patterns, or complex problem-solving when needed.

Required Qualifications

• 10+ years of enterprise software engineering experience, including 4+ years in systems, solution, platform, or enterprise architecture. Proven experience building scalable solutions within the AWS ecosystem.
• Proven experience architecting secure workflow, case-management, planning, or orchestration platforms involving workflow automation and human-in-the-loop processes.
• Strong knowledge of domain-driven design, API architecture, relational and event-driven data models, identity and access management, and enterprise integration.
• Experience designing systems that handle sensitive employee, financial, legal, or regulated data.
• Deep understanding of role-based access control and preferably attribute-based or field-level authorization.
• Technical fluency across modern full-stack technologies such as React/TypeScript and enterprise backend services using Python/FastAPI, Java/Spring, Node.js, .NET, or comparable stacks, with ability to go hands-on when needed.
• Experience with cloud architecture, CI/CD, infrastructure patterns, observability, disaster recovery, environment separation, and production support.
