Apple’s OS Security team is looking for a motivated software engineer to design, build, and deploy world-class containment and isolation mechanisms throughout our operating systems. As part of the Security Engineering and Architecture group, you will develop the foundational technologies—including compartmentalization, mandatory access control, and robust policy engines—that ensure our platforms are resilient and never just one mistake away from compromise. Our goal is for users to feel confident that our devices have their back every time they interact with an Apple product.
DESCRIPTION
In this hands-on software engineering role, you will design robust software systems and craft secure, high-performance code, collaborating across the company with everyone from our Silicon Engineering group to our Human Interface designers. We build technology deep within macOS and iOS internals, but we also lift it up through the software stack, creating ergonomic APIs that connect world-class security engineering directly to developers and users. You will have the autonomy to invest your time into the most promising areas of research and development, seeing your work scale to protect millions of people in their daily lives. Come help us push the boundaries of pragmatic, user-focused security.
Responsibilities
- Design and implement state-of-the-art isolation and compartmentalization mechanisms for iOS and macOS internals.
- Develop and maintain label-based and mandatory access systems, alongside the sophisticated policy languages and engines that enforce them.
- Build secure, usable APIs that allow both first-party and third-party developers to easily adopt our containment technologies.
- Analyze high-level frameworks and apps to ensure our security models apply pragmatically across the entire system, while operating mostly at the OS and systems programming level.
- Balance security, performance, and ease of use by breaking down ambitious, multi-year security goals into tangible, deployable steps.
- Collaborate across Apple to ensure our security technologies are not just built, but actively and correctly used by other teams to protect what matters most.
MINIMUM QUALIFICATIONS
- BS in Computer Science or equivalent experience/skills in systems programming and security.
- Strong C and low-level systems programming skills.
- Understanding of operating system internals (macOS, iOS, BSD, or Linux).
- Ability to navigate and understand code up and down the software stack (comfortable diving into kernel, low-level userland, framework, and application code).
- Familiarity with past, current, and emerging security exploits and mitigation techniques.
- Demonstrated readiness to balance concurrent priorities, manage technical debt, and deliver on tight schedules.
- Excellent partnership and communication skills to collaborate with a broad range of engineering teams.
PREFERRED QUALIFICATIONS
- Exposure to iOS and macOS (end user, administrator, and/or developer).
- Involvement in open source technologies and development communities such as FreeBSD and Linux.
- Real world kernel and/or hypervisor programming experience.
- Experience designing and implementing security policy languages.
PAY & BENEFITS

Get Access To All JobsTips for Finding OPT Sponsorship as a Security Software Engineer
Target employers with active security clearance programs
Defense contractors and federal agencies like Booz Allen Hamilton and Leidos sponsor security engineers at high rates. These employers run structured hiring pipelines and are accustomed to immigration paperwork, making OPT transitions smoother than at smaller firms.
Align your degree field with the job description
Specialty occupation approval for H-1B visa depends on your degree matching the role. A computer science or cybersecurity degree is the clearest fit. If your degree is in a related field, emphasize coursework in networking, cryptography, or systems security in your application materials.
Get relevant certifications before you apply
Certifications like CompTIA Security+, CISSP, or CEH signal job readiness to hiring managers evaluating OPT candidates. Employers sponsoring H-1B petitions for security roles often cite certifications alongside degree requirements in their LCA filings with the Department of Labor.
Apply to companies mid-H-1B cycle, not just in January
Many OPT students wait until H-1B lottery season to apply, but employers hire security engineers year-round. Starting your job search six to nine months before OPT expiration gives you negotiating time and avoids the last-minute pressure that raises red flags for sponsors.
Highlight security clearance eligibility if you have it
Some OPT holders are eligible for Secret or Top Secret clearances depending on citizenship and background. If you qualify, make this explicit in your resume and applications. Clearance-eligible candidates are significantly harder to replace, which strengthens an employer's case for sponsorship.
Ask about sponsorship policy before the final interview round
Raise OPT and future H-1B sponsorship with the recruiter after an initial positive response, not at the offer stage. Framing it as a timeline question rather than a request signals professionalism and avoids wasting weeks in a process the employer was never going to complete.
Security Software Engineer OPT: Frequently Asked Questions
Do Security Software Engineer roles commonly qualify for STEM OPT extension?
Yes. Security Software Engineer is classified under CIP code 11.0701 (Computer Science) or 14.0901 (Computer Engineering) when the underlying degree is in those fields, both of which qualify for the 24-month STEM OPT extension. Your degree must appear on the STEM Designated Degree Program List, and your employer must be E-Verify enrolled to authorize the extension.
How do I find Security Software Engineer jobs that are open to OPT candidates?
Migrate Mate filters job listings specifically for visa sponsorship and OPT eligibility, so you're not guessing which employers will work with F-1 students. Searching there surfaces Security Software Engineer roles from companies that have actively sponsored similar positions, saving you the time of screening out employers who won't consider OPT candidates.
Can I work as a Security Software Engineer as an independent contractor on OPT?
Yes, but self-employment on OPT has strict requirements. You must be actively engaged in a bona fide business related to your degree field, and you cannot work for a single client in a way that resembles regular employment. You also bear full responsibility for tracking your own work authorization dates. Consulting your DSO before pursuing contractor arrangements is strongly recommended.
What happens to my OPT if my Security Software Engineer employer is acquired or goes through a layoff?
If you're laid off, your 60-day unemployment grace period begins immediately. You can use that time to find a new role, but you cannot work during it. If your employer is acquired and your job continues under the new entity, your OPT authorization generally remains valid as long as your role and degree alignment are unchanged. Notify your DSO in either situation.
Does working in a security software role on OPT affect a future H-1B petition?
It strengthens it. Documented OPT employment in security engineering builds the evidentiary record that USCIS evaluates when assessing specialty occupation status for H-1B. Your employer's LCA filing will reference your job duties, degree requirement, and prevailing wage level. Consistent employment in a well-defined security engineering role with clear degree alignment makes adjudication more straightforward.
