Help Apple secure the world’s most advanced consumer devices, which people trust to store their personal and professional data. We believe that the best defense is a good offense, and that means finding vulnerabilities before attackers do. We're looking for talented and inspired individuals to join our team and attack Apple's products with the goal of better safeguarding our users.
DESCRIPTION
We are looking for a Senior Security Researcher to join our specialized Red Team. In this role, you will focus on the complex boundary where hardware meets software. You will hunt for vulnerabilities in the microarchitecture, memory management, and execution pipelines of modern CPUs and GPUs, as well as in the low-level code which runs on it. If you enjoy bridging the gap between hardware primitives and kernel-level exploits, and have a passion for uncovering side-channels or architectural logic flaws, this is the team for you.
MINIMUM QUALIFICATIONS
- BS in Computer Engineering or related engineering degree.
- Experience with modern CPU architectures; such as pipeline stages, caching mechanisms, MMU, or speculative execution.
- Experience with low-level software; such as in C, C++, or Assembly.
- Experience in discovering vulnerabilities or developing exploits at the OS/Hypervisor level, or in hardware-software interfaces such as CVEs, bug bounties, conference talks, or whitepapers.
PREFERRED QUALIFICATIONS
- 10+ years relevant industry experience.
- Extensive familiarity with ARM v8/v9 or x86 instruction sets.
- Proven understanding of GPU architectures (execution pipelines, memory hierarchies) and how software interfaces with them (e.g., driver vulnerability research, compute batching, memory isolation).
- Deep understanding of operating system internals, kernel architecture, and memory management.
- Experience with hardware description languages (Verilog/VHDL) or pre-silicon security validation.
- Experience with confidential computing environments.
- Familiarity with the security implications of AI/ML hardware accelerators and complex GPU workloads (e.g., memory handling in PagedAttention or Mixture of Experts).
- Familiarity with reverse engineering tools (IDA Pro, Ghidra) and dynamic analysis/debugging tools.
COMPENSATION
- Base pay range for this role is between $184,700 and $324,800, and your base pay will depend on your skills, qualifications, experience, and location.
Apple employees also have the opportunity to become an Apple shareholder through participation in Apple’s discretionary employee stock programs. Apple employees are eligible for discretionary restricted stock unit awards, and can purchase Apple stock at a discount if voluntarily participating in Apple’s Employee Stock Purchase Plan. You’ll also receive benefits including: Comprehensive medical and dental coverage, retirement benefits, a range of discounted products and free services, and for formal education related to advancing your career at Apple, reimbursement for certain educational expenses — including tuition. Additionally, this role might be eligible for discretionary bonuses or commission payments as well as relocation.
Note: Apple benefit, compensation and employee stock programs are subject to eligibility requirements and other terms of the applicable plan or program.
Apple is an equal opportunity employer that is committed to inclusion and diversity. We seek to promote equal opportunity for all applicants without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, Veteran status, or other legally protected characteristics.
At Apple, we believe accessibility is a fundamental human right. You’ll find that idea reflected in everything here — in our culture, our benefits and our digital tools. By welcoming as many perspectives as possible, we help you build a career where you feel like you belong.
Apple accepts applications to this posting on an ongoing basis.

Verify your degree field matches the role
H-1B1 visa eligibility requires your degree to align directly with the Senior Researcher position, not just research broadly. A chemistry degree won't support a computational neuroscience role. Pull the O*NET profile for your target occupation to confirm the standard educational requirement before applying.
Target employers with existing H-1B1 filing history
Research institutions, biotech firms, and federal contractors that have sponsored H-1B1 Singapore visas before already understand the consular process. Use Migrate Mate to filter job listings by employers with verified H-1B1 LCA filing history, so you're not educating a hiring team from scratch.
Request the LCA before your visa appointment
Your employer must file and receive a certified Labor Condition Application from DOL before you can apply at the consulate. Confirm the LCA certification is complete and matches your job title, worksite, and prevailing wage before scheduling your appointment at the U.S. Embassy in Singapore.
Check prevailing wage tier for your specialty
Senior Researcher roles span multiple wage levels depending on specialization and institution type. Run the OFLC Wage Search using your specific Standard Occupational Classification code and worksite zip code to verify your offered wage meets DOL requirements before the LCA is submitted.
Prepare your credential documentation for specialty occupation
Consular officers assess specialty occupation on-the-spot without the USCIS petition process as a buffer. Bring your degree transcripts, any foreign credential evaluations, and a detailed employer letter explaining why the role requires your specific disciplinary training, not just a general research background.
Plan your initial visa duration and renewal cycle
H-1B1 Singapore visas are issued in one-year increments and must be renewed annually through the consulate. Align your renewal timeline with your research contract dates and confirm your employer will resubmit the LCA for each renewal period before signing a multi-year appointment.
Frequently Asked Questions
Does a Senior Researcher role qualify as a specialty occupation for the H-1B1 Singapore visa?
Yes, provided the position requires at least a bachelor's degree in a directly related field such as biology, chemistry, computer science, or another relevant discipline. Roles that accept any degree regardless of field, or that substitute years of experience for educational requirements without restriction, may not qualify. Your employer's LCA and supporting documentation must establish the specific degree requirement for your position.
How does the H-1B1 Singapore visa compare to the H-1B for Senior Researcher positions?
The H-1B1 Singapore visa has no lottery, no USCIS petition filing requirement, and a dedicated annual cap of 5,400 visas that rarely fills, making it significantly more accessible for Singaporean nationals than the H-1B visa. The trade-off is that H-1B1 visas are issued in one-year increments requiring annual consular renewal, whereas approved H-1B petitions can cover up to three years initially.
Where can I find Senior Researcher jobs that specifically offer H-1B1 Singapore visa sponsorship?
Migrate Mate lets you search for Senior Researcher roles filtered by employers with verified H-1B1 visa LCA filing history, so you can identify institutions already familiar with the consular process. General job boards don't filter by visa type or filing history, which means you'd have to assess each employer's sponsorship experience individually before investing time in an application.
Can I work at multiple research sites on a single H-1B1 Singapore visa?
Each primary worksite must be covered by a separate LCA certified by DOL before you work there. If your Senior Researcher role involves field work, satellite labs, or affiliated institutions in different metropolitan areas, your employer needs to file additional LCAs for each location. Short-term placements at a client or partner site may qualify under a blanket LCA if the employer has one in place.
What happens to my H-1B1 status if my research grant ends before my visa expires?
H-1B1 visa status is tied to your employer and the specific position described in the LCA. If your funding ends and your employment terminates, your authorized status ends with it. Unlike H-1B, there's no statutory grace period codified for H-1B1, so you should immediately discuss a new employer filing or a change of status with your employer's immigration contact if your grant timeline is uncertain.
