Dear Hiring Manager,
I am applying for my first full-time security engineer role after completing project work that used threat modelling, SAST, dependency scanning, IAM reviews, cloud security controls, Python, and SIEM workflows. My strongest evidence is a recent portfolio project where I triaged dependency risk, improved secrets handling, and built a lightweight check that caught unsafe configuration before release.
I know an entry-level hire has to be easy to coach and useful quickly. Your team needs application security judgement, vulnerability triage, identity controls, and practical developer enablement, and my strongest examples sit in that exact area. I would use this letter to show the connection with one specific project, the constraints I worked under, and the judgement I brought to the decision points.
A recent example is that I triaged dependency risk, improved secrets handling, and built a lightweight check that caught unsafe configuration before release. That work required threat modelling, SAST, dependency scanning, IAM reviews, cloud security controls, Python, and SIEM workflows, but the more important point is how I made decisions, explained tradeoffs, and followed the result through after release.
I would be glad to discuss the project work, tradeoffs, and feedback that shaped it. security teams value engineers who reduce real risk without turning every review into a blocker, so I would keep the letter concise, evidence-led, and tied to the outcomes the hiring team is likely to care about.
Yours sincerely, Alex Morgan
