About the role

Roblox is seeking a Senior Security Software Engineer on Application Security to hands-on design, ship, and scale security controls integrated into developer workflows and CI/CD pipelines. You will bridge threat modeling, code reviews, penetration testing, and vulnerability triage with automated tooling (SAST, SCA, secrets detection, fuzzing) and pioneer guardrails for AI-assisted developer workflows to mitigate prompt injections and data exfiltration.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
