Hiring a security architect: profile and interview

Hiring a security architect is one of the hardest cyber hires to get right: the title is vague, good profiles are rare and a mistake often only shows after several months. This guide helps you define what you really expect from the role, check the right skills and build an interview that reveals how the candidate thinks.

What a security architect does

A security architect makes sure security is designed in from the start rather than bolted on afterwards. They step in early on projects, propose structural choices and keep those choices consistent from one project to the next.

In practice, the role covers four areas:

• Supporting projects: analysing the risks of a new service, proposing a target architecture, approving technical choices before go-live.
• Setting standards: architecture principles, reference patterns (authentication, internet exposure, secrets management, segmentation), minimum requirements for teams.
• Evolving the foundations: identity, network, logging, encryption, endpoints, with a realistic roadmap.
• Advising leadership and the CISO: turning threats and regulatory obligations into investment decisions.

An architect is neither an auditor nor an administrator. They design, they make trade-offs and they persuade. Their success is measured by the quality of the systems others build by following their guidance.

Three profiles behind one title

Before writing the job ad, choose the main focus of the role. The three profiles below overlap, but they come from different backgrounds and have different reflexes.

In a mid-sized company, you often look for a cross-functional architect who covers all three areas reasonably well and goes deep in one. That is a fair choice, as long as you say clearly which one. If your need is mostly cloud, our guide to hiring a cloud security engineer will help you tell the engineer and the architect apart.

The skills to check

Technical foundations

An architect should have done the work before designing it. Check for a solid understanding of:

• identity and access management, federation, strong authentication, privileged accounts;
• networking and segmentation, service exposure, remote access;
• encryption, key and secrets management;
• logging and detection capability: what an architecture lets you see during an incident;
• application and API security principles;
• at least one cloud environment, even if the role is mostly on-premises.

Method

The architect should be able to analyse threats in a structured way without reciting a framework. A risk analysis method such as EBIOS Risk Manager, published by ANSSI, or a threat modelling approach are useful references. What matters is the ability to start from a business need, identify what can go wrong and propose proportionate controls.

People skills

This is often where the hire is won or lost:

• Writing. A clear architecture document, with decisions recorded alongside their reasons and alternatives.
• Persuading without authority. The architect influences teams that do not report to them.
• Making trade-offs. Accepting residual risk when a control costs more than it brings, and explaining why.
• Saying no with an alternative. A refusal without a proposal blocks the project and pushes teams to work around security.

Where to find these profiles

Security architects are rarely on the market. Most come from neighbouring roles and are well settled.

• Experienced security engineers who want to move from implementation to design.
• IT or infrastructure architects who have built a real security culture.
• Senior developers or AppSec specialists, for application-focused roles. Our article on hiring an application security engineer covers this talent pool.
• Consultants who have seen many different architectures and want to commit to one organisation.

A candidate without the architect title but with concrete design work behind them is often worth more than a title with nothing behind it.

Building the interview

Textbook questions are not enough to assess an architect. You need to see them reason through a realistic case. Here is a four-step process.

1. A first conversation about their background, the architectures they designed or inherited, the size of the environments and the decisions they are proudest of.
2. An architecture case study prepared in advance, with no sensitive data from your company.
3. A presentation to a panel: a member of the security team, a technical lead or IT architect, and ideally someone from a project team.
4. A final conversation with the manager, often the CISO, about the mandate, governance and prospects.

A sample case study

Offer a simple, open scenario, for example: "We are launching a customer portal on the internet, connected to our billing system hosted on-premises. The teams want to deploy it with a cloud provider. Propose an architecture and explain your choices."

Give the candidate time to prepare a diagram and a few pages. During the presentation, watch whether they:

• ask about the business and the data before drawing;
• identify the main threats and rank them;
• propose proportionate controls without over-protecting everything;
• explain what they deliberately left out;
• account for operations, detection and cost.

Useful questions during the presentation

• "If the project team can apply only one of your recommendations before launch, which one and why?"
• "What in your architecture would let us detect a compromise of the portal?"
• "The business refuses strong authentication for customers. What do you propose?"
• "Tell us about an architecture decision you made and now regret."

To score fairly, use a grid shared by the whole panel. Our guide to assessing cybersecurity skills offers a method that applies here.

Common mistakes

• Hiring a single-tool expert. An architect must think beyond one product or vendor.
• Confusing architect and project manager. Tracking schedules is not the core of the role.
• Giving no mandate. Without a seat in project approval bodies, the architect writes recommendations nobody applies.
• Underestimating writing. A great technician who cannot document their choices leaves little of lasting use.
• Placing the role too far from projects. The architect must be consulted early, not the day before go-live.
• Dragging out the process. These candidates often have several options. Long gaps between stages lose the best ones.

Reporting line and mandate

A security architect usually reports to the CISO, sometimes to the CTO or an enterprise architecture team. Each option has its logic: closeness to security governance in the first case, closeness to projects in the second. Whatever you choose, write down what the architect can approve, refuse or escalate. If the CISO role itself is open, our guide to hiring a CISO will help you think about both roles together.

Regulation often reinforces the need. Entities in scope of the NIS2 directive must demonstrate a risk management approach, which implies documented architecture choices. Our article on the profiles to hire for NIS2 places the architect within that picture.

In short

To hire a security architect, first choose the main focus of the role (infrastructure, cloud or application), then check the technical foundations, the threat analysis method and the ability to persuade. Assess with an architecture case study presented to a panel, give the role a real mandate and keep the process short.
