Software architect roles and responsibilities come down to one job: owning the technical decisions that are costly to reverse. When nobody owns them, the first engineer to pick a data store or split a service owns them by default, and the business finds out later, which is our judgment. This guide shows what an architect does and who decides what, then gives a short test for whether your custom software development<\/a> project needs a dedicated architect.<\/p>\n

What is a software architect?<\/strong><\/h2>\n

In our judgment, a software architect is the person who owns the system-level technical decisions that are costly to reverse. The Software Engineering Institute describes software architecture as the set of design decisions that shape a system’s overall structure and behavior.<\/p>\n

Martin Fowler argued in Who Needs an Architect?<\/a> (IEEE Software, 2003) that one of an architect’s most important tasks is to eliminate irreversibility. On a small team, a senior engineer often holds the role without the title, which is our judgment, not a standard. Our software architecture guide<\/a> explains the subject the role works on.<\/p>\n

What does a software architect do?<\/strong><\/h2>\n

A software architect turns business goals into a system structure and keeps that structure intact from design through production. Microsoft’s architect guidance<\/a> covers the full lifecycle of a workload. TekRevol groups that work into design, build, and run.<\/p>\n

Microsoft’s architect pages cover the cloud solution architect, so applying them to every software architect is our reading.<\/p>\n\n\n\n\n\n\n\n\n\n\n

Microsoft adds two cautions. Proof of concept code is not production code, so it should be marked disposable and rebuilt to the team’s standards. The architect’s work also continues after launch, because the same guidance has the architect review changes and support audits once the system is live.<\/p>\n

For how a proof of concept works, see our guide to what a proof of concept is in software development<\/a>.<\/p>\n

Who decides what on a software project?<\/strong><\/h2>\n

The responsibilities of a software architect cover decisions that span components and are costly to reverse. The engineering team and the product owner own the rest, as the table shows.<\/p>\n

The table is the TekRevol Decision Rights Table. It is our judgment, and a different team could draw the lines elsewhere. It separates architecture decisions from design decisions by how many components they touch and how costly they are to reverse.<\/p>\n\n\n\n\n\n\n\n\n\n
Decision<\/strong><\/td>\nArchitect<\/strong><\/td>\nEngineering team<\/strong><\/td>\nProduct owner<\/strong><\/td>\n<\/tr>\n
Split the product into separate services<\/strong><\/td>\nOwns<\/td>\nAdvises<\/td>\nInformed<\/td>\n<\/tr>\n
Choose the main data store<\/strong><\/td>\nOwns<\/td>\nShares<\/td>\nInformed<\/td>\n<\/tr>\n

Pick REST or gRPC for one internal API<\/strong><\/td>\nAdvises<\/td>\nOwns<\/td>\nNo role<\/td>\n<\/tr>\n

Set release scope and dates<\/strong><\/td>\nAdvises<\/td>\nAdvises<\/td>\nOwns<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

A decision moves up the table when more components depend on it. In our judgment, a cache inside one service is the team’s call until three other services start reading from it, and then it becomes the architect’s.<\/p>\n

How is a software architect different from a software engineer or tech lead?<\/strong><\/h2>\n

The role of a software architect differs from an engineer’s or tech lead’s in scope: the architect answers for the whole system, while the others answer for a part of it. The table sets the roles side by side, and it is our reading of common usage.<\/p>\n\n\n\n\n\n\n\n
Role<\/strong><\/td>\nFocus<\/strong><\/td>\nQuestion they answer<\/strong><\/td>\n<\/tr>\n
Senior software engineer<\/strong><\/td>\nOne component or feature<\/td>\nHow should this part be built?<\/td>\n<\/tr>\n
Tech lead<\/strong><\/td>\nDelivery for one team<\/td>\nHow does the team ship on time?<\/td>\n<\/tr>\n
Software architect<\/strong><\/td>\nThe whole system<\/td>\nHow do the parts fit, and how do they stay changeable?<\/td>\n<\/tr>\n
Project manager<\/strong><\/td>\nSchedule and budget<\/td>\nWhen will it ship, and at what cost?<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Small teams often combine roles, so one person may be both tech lead and architect. That works until the system spans several teams. For how roles and teams are organized around a project, see our guide to software development team structure<\/a>.<\/p>\n

What are the types of software architects?<\/strong><\/h2>\n

Titles vary by company, so judge an architect by scope, not by label. Five labels are common, and the table gives the scope each one usually covers.<\/p>\n\n\n\n\n\n\n\n\n
Type<\/strong><\/td>\nScope<\/strong><\/td>\n<\/tr>\n
Software architect<\/strong><\/td>\nThe structure of one product or system<\/td>\n<\/tr>\n
Solution architect<\/strong><\/td>\nFitting technology to a business problem, often across several systems<\/td>\n<\/tr>\n
Enterprise architect<\/strong><\/td>\nAlignment of IT across the whole organization<\/td>\n<\/tr>\n
Data architect<\/strong><\/td>\nHow data is modeled and moved<\/td>\n<\/tr>\n
Cloud architect<\/strong><\/td>\nDesign and operation of cloud infrastructure<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

This is our summary of common usage, not a standard. Some companies use the titles interchangeably.<\/p>\n

What skills and requirements does a software architect need?<\/strong><\/h2>\n

A software architect needs enough hands-on depth to judge a design and enough communication skill to explain its trade-offs to people who do not code. Microsoft’s architect guidance asks the architect to stay clear on business requirements and to stay hands-on, because decisions should rest on experiments and real work.<\/p>\n

In our judgment, four skills matter most: system design depth, trade-off analysis, clear written communication, and knowledge of your industry. Job requirements for years of experience vary too widely between employers to quote a reliable figure, which is our judgment. A better test is to ask what the candidate has designed and what they would change about it.<\/p>\n

What should a software architect job description include?<\/strong><\/h2>\n

A software architect job description should state the decisions the person owns and the outcomes they answer for, not a list of tools. The table gives five sections to write.<\/p>\n\n\n\n\n\n\n\n\n
Section<\/strong><\/td>\nWhat to write<\/strong><\/td>\n<\/tr>\n
Decisions owned<\/strong><\/td>\nThe kinds of choices the person makes alone, taken from the decision rights table above<\/td>\n<\/tr>\n
Outcomes<\/strong><\/td>\nThe quality goals the person answers for, such as availability or release speed<\/td>\n<\/tr>\n
Working relationships<\/strong><\/td>\nWhich teams the architect advises and who they report to<\/td>\n<\/tr>\n
Required depth<\/strong><\/td>\nThe systems the person has designed and kept running<\/td>\n<\/tr>\n
Limits<\/strong><\/td>\nWhich decisions need sign-off from the product owner or leadership<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

This checklist is our judgment, not a template. A job description that lists only tools hires a senior engineer, which may be the right hire, but it is not an architect.<\/p>\n

Does your project need a dedicated software architect?<\/strong><\/h2>\n

A dedicated architect pays off when more than one team builds on the same system or when the next choices are costly to reverse. Otherwise, a senior engineer can usually hold the role. Answer four questions:<\/p>\n
