The short version

A solution architect designs how a specific system or project should be built: the technologies, the structure, and the way the pieces fit together to meet the requirements and stand the test of time. Hiring one on contract or through a vetted network lets you add senior design capability for a defined project, which matters most when you are building or transforming something significant and need it architected properly before the build begins.

• Typical engagement: 3 to 12 months on contract, usually tied to a specific project or programme
• Day rates in Australia: A$1,000 to A$1,600/day depending on seniority, domain, and complexity
• Specialisations: cloud (AWS, Azure), application and integration architecture, data, and platform-specific solution design
• Hire one when: you're building or transforming a significant system and need it designed properly first
• Time to deploy: curated shortlists in 48 hours via Expert360
• Engagement types: contract, project-based, fractional, or interim

What is a solution architect?

A solution architect designs the technical solution for a specific business problem, system, or project. They take the requirements and the constraints, then design how the solution should be built: which technologies, how the components connect, how it integrates with what already exists, and how it will scale, perform, and stay secure. They sit between the high-level strategy and the hands-on build, translating what the business needs into a design the engineers can deliver.

In Australia, demand for contract solution architects is strong and steady, driven by transformation programmes, cloud migrations, and system integrations across banking, government, higher education, and enterprise. Cloud platform expertise, particularly AWS and Azure, is in heavy demand, and many roles call for it specifically. Solution architects are a common contract hire because their work is naturally project-shaped: intense during design, lighter once the build is underway.

The title sits alongside several related ones, and the distinctions matter when you hire. The short version:

• Enterprise architect: works at the whole-of-organisation strategic level; the solution architect designs specific systems within that strategy.
• Technical architect: focuses on the deep technical design of a particular technology or platform, often more specialised than a solution architect.
• Cloud or AWS architect: a solution architect specialised in designing for a specific cloud platform.
• Software engineer or developer: builds the solution; the solution architect designs how it should be built.

When you describe your project to Expert360, we help you work out whether you need solution-level design, enterprise strategy, or hands-on engineering.

When should you hire a solution architect?

The trigger is usually a significant system or project that needs designing properly before, or during, the build. A contract solution architect is the right call when that work is real and time-bound.

• You're building something significant. A major new system or platform needs its architecture designed before the build, so it is built right the first time.
• You're migrating to the cloud. A move to AWS, Azure, or another platform needs someone to design the target architecture and the path to it.
• You're integrating systems. Connecting systems, or building something that spans several, needs an architect to design how they fit together.
• You're transforming a system. Replacing or significantly changing a system needs a design that handles the transition as well as the destination.
• Your project lacks design ownership. Developers are building without a coherent overall design, and you need someone to own the architecture.
• You need independent design assurance. A vendor or team has proposed a design, and you want a senior, independent architect to validate it before you commit.

If two or more of these match, a contract solution architect is likely the right next step.

How much does a solution architect cost in Australia?

Solution architects are senior, well-paid technology contractors, sitting below enterprise architects but above hands-on engineers. Rates vary with seniority, domain, and complexity.

The below rates are indicative only. Experts in our network set their own rates, and you'll be able to compare real rates after requesting a talent shortlist.

Solution architect: A$1,000–A$1,250/day

An experienced architect designing solutions for defined projects with limited oversight. Suits a single significant system or a well-scoped piece of design work.

Senior solution architect: A$1,250–A$1,450/day

Deep experience designing complex solutions, leading architecture on large programmes, and handling demanding integration or cloud work. Suits major transformations and complex, multi-system designs. Strong AWS or Azure expertise sits here.

Lead or principal solution architect: A$1,450–A$1,600/day and above

Top-tier architects leading solution design across large, high-stakes programmes, or with scarce specialist or cleared-government experience. The top of the band reflects scarce skills and significant design accountability.

On a fractional basis, expect roughly A$10,000 to A$22,000 per month for 2 to 3 days a week, which suits ongoing design oversight across projects without a full-time hire. Rates rise for scarce cloud and integration skills, cleared government work, and complex programmes, and ease for longer commitments.

What drives the variance:

• Domain and platform: in-demand cloud and integration skills command a premium
• Complexity: complex, multi-system designs pay above single-system work
• Sector: banking, government, and large transformation programmes pay the most
• Engagement length: longer contracts often come with a lower day rate

For comparison, a permanent solution architect in Australia earns roughly A$133,000 to A$190,000 base depending on level and specialisation, with senior cloud architects and top firms higher, or more fully loaded with superannuation and on-costs. A contract architect costs more per day but adds no on-costs, ramps fast, and ends cleanly when the design work is done, which suits the project-shaped nature of the role well.

Solution architect vs enterprise architect – what's the difference?

This is the distinction that matters most when you hire, because the two are often confused and priced differently. Here is how they differ in practice.

A solution architect works at the level of a specific system or project, designing how that solution should be built, integrated, and delivered. Their output is a buildable design for a defined problem. Day rates run A$1,000 to A$1,600/day. Best when you have a specific system or project to design.

An enterprise architect works at the whole-of-organisation level, setting technology strategy and standards across the entire estate, within which solution architects design. Their day rates run higher, up to A$2,000/day. Best when the challenge spans the whole organisation.

The practical point: most projects need a solution architect, not an enterprise architect. Reach for enterprise architecture when the challenge is organisation-wide strategy rather than a specific build. On a large programme you often need both, working at their respective levels. The costly mismatch is paying enterprise rates for solution-level work, or expecting a solution architect to set enterprise-wide strategy. When you describe your need to Expert360, we help you match the right level.

What does a solution architect actually do?

The day-to-day varies by project, but most contract solution architects cover some combination of the following.

• Understand the requirements. Working with the business and technical teams to understand what the solution actually needs to do, and within what constraints.
• Design the solution. Deciding the technologies, structure, and approach, and documenting how the solution should be built.
• Design the integrations. Working out how the solution connects to existing systems and data, which is often where the real complexity sits.
• Design for the non-functionals. Making sure the design handles performance, scale, security, and reliability, not just the features.
• Guide the build. Supporting the engineers who build it, answering design questions, and keeping the build true to the architecture.
• Validate against standards. Ensuring the design fits the organisation's architecture standards and any enterprise architect's strategy.
• Make and document trade-offs. Choosing between competing options and recording why, so the decisions are clear and defensible later.

A contract engagement usually starts with understanding the requirements and constraints, then moves into design, with the architect also guiding the build and resolving design questions as they arise.

How to choose the right solution architect

The real risk in hiring a solution architect is rarely whether they can draw a diagram. It is whether they design solutions that actually get built and work, with the right platform experience, and the pragmatism to balance the ideal against the deadline.

• Platform and domain fit. Match the architect to your actual stack and domain, whether AWS, Azure, integration-heavy, or data-centric. Deep experience in one platform is not automatic in another.
• Designs that got built. The best test is whether their designs were successfully delivered. Ask for systems they architected that went live and worked.
• Build-awareness. Good solution architects understand the realities of building. Ask how they stay close to the engineers and adjust the design when the build hits reality.
• Non-functional rigour. Many designs handle the features but not the performance, scale, or security. Ask how they design for these.
• Pragmatism. A perfect design that misses the deadline is a failure. Ask how they balance the ideal architecture against time and budget.
• References from real projects. A reference from a delivery lead or engineering manager they worked with tells you most. Ask whether the design held up through the build.

Every solution architect in the Expert360 network is vetted for real design experience and reference-checked against the platforms and projects they claim, so the shortlist you see reflects architects who have designed systems like yours.

Frequently asked questions

What does a solution architect do?

A solution architect designs how a specific system or project should be built. They understand the requirements, design the solution and its integrations, design for performance, scale, and security, guide the engineers who build it, and make and document the key technical trade-offs along the way.

What's the difference between a solution architect and an enterprise architect?

A solution architect designs a specific system or project. An enterprise architect works at the whole-of-organisation level, setting technology strategy and standards across the estate, within which solution architects design. Most projects need a solution architect; large programmes often need both, and they are priced differently.

What's the difference between a solution architect and a developer?

A solution architect designs how a system should be built; a developer or software engineer builds it. The architect makes the high-level technology and structural decisions and guides the build, while the engineers write the code that delivers the design. On larger projects the roles are distinct.

How much does it cost to hire a solution architect in Australia?

Contract solution architects in Australia typically charge A$1,000 to A$1,600 per day. A solution architect sits around A$1,000 to A$1,250/day, a senior architect A$1,250 to A$1,450/day, and a lead or principal A$1,450 to A$1,600/day or higher. They sit below enterprise architects but above hands-on engineers.

Do I need a solution architect or an enterprise architect?

If you have a specific system or project to design and build, you need a solution architect. If your challenge is organisation-wide technology strategy, you need an enterprise architect. Most projects call for a solution architect, while large transformations often need both working at their respective levels.

Should I hire a cloud-specialised solution architect?

If your project is built on or moving to a specific cloud platform, yes. AWS and Azure solution architects bring deep, platform-specific design knowledge that matters for cloud work, and AWS or Azure experience is frequently a specific requirement in Australian roles. Match the architect to your actual platform.

How quickly can I hire a solution architect through Expert360?

Expert360 provides a curated shortlist of vetted solution architects within 48 hours of you describing your needs. Because the network is pre-vetted, you can typically have an architect engaged and starting within one to two weeks, far faster than a permanent search, which suits the project-shaped nature of the role.

Can a solution architect work remotely?

Much solution architecture work suits remote and hybrid arrangements, and many contract architects work this way, with periodic on-site time for design workshops and stakeholder engagement. Cleared government transformation work usually requires on-site presence and a security clearance.
