As a Solution Architect, you are the link between business needs and technical execution. You ensure roadmap concepts are feasible, sequenced logically, and translated into actionable, end‑to‑end solution designs. You work across value streams, bridging product, security, infrastructure and enterprise IT, making sure our solutions are robust, future‑proof, and deliver value efficiently.
You combine impact assessment with solution exploration: diversifying options, assessing trade‑offs, and shaping transition paths that guide delivery teams while preserving autonomy.
What your job looks like
End‑to‑End Solution Design
Produce logical and physical solution designs across applications, integrations, and infrastructure.
Tailor non-functional requirements (NFRs) such as security, performance, compliance, and availability.
Define and maintain integration guidelines and system-wide principles.
Separation of Concerns & Component Roles
Define clear responsibilities, boundaries, and interfaces for components (domain, orchestration, integration, protocol/interface).
Ensure maintainability and avoid overlap by clarifying roles and responsibilities in system decomposition.
Support transitions from monoliths to modular/microservice architectures.
Solution Alternatives & Trade-offs
Ensure solution diversification and structured trade‑off assessment.
Provide clear recommendations backed by transparent rationale in ADRs (Architecture Decision Records).
Transition & Roadmap Support
Provide transitional architecture patterns and high‑level sequencing plans to de‑risk delivery.
Pre‑wire initiatives in governance (e.g., Portfolio Committee) to prevent surprises and improve decision‑making.
Decision Tracking & Standards
Maintain an ADR repository and trade‑off rationale.
Align solutions with product guardrails, zero‑trust security practices, and architectural modelling conventions (C4, ArchiMate).
Enablement over Control
Apply just‑enough architecture: more guardrails and standards where maturity is low; lighter guidance where teams are seasoned.
Strategic Support
Support Enterprise Architects in impact analyses for acquisitions, new tooling integration, or strategic shifts.
Job requirements
Proven experience as a Solution Architect (or similar role) in SaaS or other high‑availability environments.
Strong background in software engineering and system integration.

Skilled in NFR engineering (availability, compliance, performance, security) and transition planning under delivery constraints.
Comfortable leading option generation and trade‑off discussions, even with incomplete information.
Excellent communication skills: able to translate complex technical trade‑offs into clear guidance for both engineering and business stakeholders.
