Define a first security engineering role from the risks the startup needs to reduce and the work required to reduce them. “Own security” is too broad unless the team has also defined authority, resources, and specialist support.
A security hire can lead improvements, but product, infrastructure, and leadership teams still have responsibilities.
Turn risks into work
| Concern | Possible work | Boundary to clarify |
|---|---|---|
| Unsafe product behavior | Design review and engineering changes | Who implements and approves releases? |
| Excessive access | Access design, review, and operational controls | Who owns identity systems? |
| Software supply chain | Dependency and build protections | Who maintains delivery infrastructure? |
| Vulnerability response | Triage, remediation coordination, and learning | Who decides urgency and accepts residual risk? |
| Customer assurance | Accurate evidence and explanations | Who handles contractual or legal commitments? |
These are planning examples, not a complete security program or compliance checklist.
Choose the first emphasis
NIST’s Secure Software Development Framework organizes practices around organizational preparation, protecting software, producing secure software, and responding to vulnerabilities. It recommends adapting priorities to risk and resources. NIST SSDF.
Use that breadth to avoid confusing one specialty with the whole function. A product security engineer, infrastructure security engineer, and governance specialist can bring different strengths.
Define implementation authority
State whether the person will write code, change infrastructure, review designs, coordinate remediation, or build processes. Clarify how teams resolve disagreements about priorities.
If the hire can identify problems but cannot obtain engineering time to address them, the mandate needs leadership support before recruiting begins.
Assess practical judgment
Use a fictional system description and ask the candidate to identify important risks, missing information, and a prioritized action plan.
Look for proportionate recommendations, clear communication, and recognition of limits. A long list of tools or vulnerabilities is less useful than explaining what should change first and who must be involved.
Be honest about coverage
Specify the support available for specialist audits, incident response, legal questions, and other areas outside the hire’s experience. Do not imply that one employee guarantees compliance or eliminates risk.
Use the security prioritization exercise and hands-on leadership mandate. Discuss a security engineering search with Refery.
