Both are senior architecture roles but with different scope.
Solution Architect (SA):
- Project / programme level.
- Designs the solution for a specific business problem.
- Trade-offs between Salesforce features, customisation, packages, integration.
- Cross-cloud (Sales + Service + Marketing + Industries).
- Typically reports into a delivery team or leads one.
Technical Architect (TA):
- Enterprise / platform level.
- Sets technical standards across all projects.
- Reference architectures.
- Code review at the framework level.
- Typically reports to CIO / VP Engineering.
- Often a Certified Technical Architect (CTA).
Overlap:
Both make architectural decisions, both engage with business. The split is more about scope:
- One project, multiple components -> Solution Architect.
- Many projects, platform-wide consistency -> Technical Architect.
Typical career path:
Senior Consultant -> Solution Architect -> Technical Architect -> CTA.
Title inflation note: many firms call senior consultants "architect" when the role is really senior consultant. The real test: do they own architecture decisions and have authority to enforce them?
A good architect's value isn't in the title — it's in making the difficult decisions about complex systems that hold up over years.
