PhD internships at Our Company provide students with the opportunity to actively contribute to our products and research, and to the organization's future plans and emerging technologies. Our dynamic internship experience blends hands-on learning, enriching community-building and development events, and collaboration with industry experts.
Applications will be reviewed on a rolling basis - we encourage you to apply early. Please state your availability clearly in your resume (Start date, End date).
Team Introduction: Our Business Integrity team has a strong user focus and a dedication to technical excellence. We aim to meet our users’ needs with reliable and high-performing platforms and services. We are looking for strong machine learning engineers who are excited to grow their business understanding, build highly scalable machine learning models, and partner across disciplines with global teams, in pursuit of excellence. Given the fast growth of TikTok in the world, we are working on building a next-generation content understanding system for TikTok monetization. We are seeking Research Engineers who are experienced in machine learning, which can help us create an ecosystem that rewards high-quality user experience and advertiser value.
Topic Content: With the explosive growth of digital content, intelligent moderation has become a core capability for internet platforms. However, as moderation scenarios grow increasingly complex and adversarial tactics continue to evolve, traditional approaches are facing unprecedented challenges. The current landscape is characterized by multiple technical difficulties, including the dynamic nature of moderation rules, content complexity, sample scarcity, escalating adversarial behaviors, and a lack of interpretability. In particular, existing open-source large models often do not perform as effectively as we expect in scenarios involving evolving moderation rules, long-form text, long temporal sequences, multi-languages, limited sample data, and adversarial content generated by AIGC.
Responsibilities:
In this role, you will build a leading moderation system that enables end-to-end capabilities for accurate rejection decisions, interpretable reasoning, and intelligent remediation, achieving fully automated moderation with performance surpassing human benchmarks.
MINIMUM QUALIFICATIONS:
- Currently pursuing a PhD in Software Development, Computer Science, Computer Engineering, or a related technical discipline.
- Modeling experience in one or more of the areas: Ads, Search engine, Recommender System, NLP/CV, multimodal, agent technologies.
- Have a solid foundation in algorithms related to LLMs, including but not limited to comprehensive learning and practical experience in areas such as single-modal LLM application and deployment.
- Strong publications record in top conferences (e.g., ICLR, NeurIPS, ICML, ACL, EMNLP, N CVPR, ICCV, and ECCV).

Get Access To All JobsTips for Finding J-1 Visa Sponsorship as an Applied Scientist
Align your CV to research outputs
Research Scholar and Specialist categories require documented evidence of your scientific contributions. Format your CV to lead with publications, patents, and funded projects rather than job titles, since designated sponsors evaluate academic and technical credentials closely before issuing a DS-2019.
Target host employers with active research arms
Search for Applied Scientist openings at organizations that already partner with designated sponsors like IIE or Cultural Vistas. University-affiliated labs, national research institutes, and R&D-intensive tech firms are the most likely host employers for this category.
Use Migrate Mate to find J-1-aligned roles
Filter your Applied Scientist job search on Migrate Mate to surface U.S. employers whose hiring history and role structures align with J-1 sponsorship, saving you from applying to host organizations that have no established sponsor relationship.
Check your country's home residency requirement
Many Applied Scientists on J-1 visas are subject to the two-year home residency requirement under INA Section 212(e), particularly if your exchange is government-funded or your home country is on the Exchange Visitor Skills List. Confirm your status before accepting an offer.
Negotiate training plan scope before signing
Your designated sponsor requires a detailed Training Plan tied to your specific research objectives. Agree on the scope of your Applied Scientist role with your host employer before the sponsor drafts this document, since changes after DS-2019 issuance can delay your start date.
Confirm the host employer's SEVIS compliance history
Your designated sponsor will assess whether the host employer can meet Student and Exchange Visitor Information System (SEVIS) reporting requirements, including workspace verification and supervisor credentials. Ask your prospective host whether they've previously hosted J-1 Research Scholars or Specialists.

Find Applied Scientist JobsApplied Scientist J-1 Visa: Frequently Asked Questions
Which J-1 program category fits an Applied Scientist role?
Most Applied Scientist positions fall under the Research Scholar or Specialist category. Research Scholar applies when you're conducting independent research at a U.S. institution, typically requiring a graduate degree and a scholarly research agenda. Specialist applies to experienced professionals with expertise in a technical field who are undertaking a structured observation or consultation program, not independent research. Your host employer and designated sponsor determine which category fits your specific role and qualifications.
Who actually sponsors my J-1 visa as an Applied Scientist?
The J-1 visa sponsor is a U.S. Department of State-designated organization, such as IIE, Cultural Vistas, or a university's international office, not your host employer. The host organization hires you and supervises your work, but the designated sponsor issues your DS-2019 form, enrolls you in SEVIS, and is legally responsible for your compliance throughout the program. Confirming that your host employer has an existing relationship with a designated sponsor is a critical step before accepting any offer.
Does the two-year home residency requirement affect Applied Scientists?
It often does. Applied Scientists funded by a home-country government or working in a field listed on the Exchange Visitor Skills List for their nationality are typically subject to the two-year home residency requirement under INA Section 212(e). This means you must return to your home country for two years before applying for H-1B, L-1, or immigrant visa status. A waiver is possible through DOL, a federal agency, or a hardship claim, but the process takes time and is not guaranteed.
How do I find Applied Scientist roles where the host employer already works with a J-1 sponsor?
Migrate Mate lets you search Applied Scientist openings and filter for U.S. employers whose hiring patterns align with J-1 sponsorship categories. This saves significant time compared to applying broadly and then discovering a host employer has no designated sponsor relationship. Targeting employers with established research programs, university affiliations, or federal contractor status also increases the likelihood they've navigated J-1 hosting before.
Can I switch host employers mid-program as a J-1 Applied Scientist?
Yes, but the process requires your designated sponsor's approval and typically involves issuing a new or amended DS-2019. You cannot simply transfer to a new host employer without notifying your sponsor, since any change in program site, supervisor, or scope must be reflected in SEVIS. Some sponsors restrict mid-program transfers depending on how far you are into your authorized stay, so review your original Training Plan and program agreement before pursuing a host change.
