ABOUT THE TEAM
Join ByteDance’s database R&D team, where you’ll build and own cutting-edge database products supporting ByteDance’s global infrastructure. Our diverse portfolio includes relational databases, distributed caches, key-value stores, document databases, graph databases, wide-column stores, search engines, and multi-model databases.
ABOUT THE ROLE
We are building the next-generation AI-native database systems—intelligent, multimodal, and designed for the era of large models. Our systems are not just data stores; they’re reasoning engines, retrieval platforms, and real-time memory for AI agents. As a Software Engineer or Researcher, you will be at the forefront of rethinking how databases work when built from the ground up for AI workloads. You’ll help create infrastructure that powers intelligent systems across TikTok, CapCut, and future applications that haven’t been imagined yet.
We are looking for talented individuals to join us for an internship. PhD internships at Our Company provide students with the opportunity to actively contribute to our products and research, as well as to the organization's future plans and emerging technologies.
Our dynamic internship experience blends hands-on learning, enriching community-building and professional development events, and collaboration with industry experts.
Applications will be reviewed on a rolling basis, so we encourage you to apply early. Please clearly state your availability in your resume (Start date, End date).

Get Access To All JobsTips for Finding Scientist Jobs at ByteDance
Align your research to ByteDance's core systems
ByteDance Scientist roles cluster around recommendation algorithms, natural language processing, and computer vision. Framing your CV and publications around these areas signals direct fit to technical recruiters screening for applied research alignment, not just academic credentials.
Confirm your visa category before applying
ByteDance sponsors H-1B, H-1B1 visa, and E-3 visas for Scientists. If you're Australian, the E-3 bypasses the H-1B lottery entirely. Knowing which category applies to your passport shapes your timeline and what you ask during recruiter conversations.
Target teams that file LCAs year-round
ByteDance operates cap-exempt hiring windows for roles that don't depend on the annual H-1B lottery. Search DOL's FLAG system for ByteDance LCA filings under job titles like Research Scientist or Applied Scientist to identify which teams file consistently outside the April cap season.
Prepare for a technically rigorous interview loop
ByteDance Scientist interviews typically span multiple rounds covering coding, system design, and original research. Have a published paper or significant project ready to defend in depth. The offer timeline can run six to eight weeks, so factor that into your visa status planning.
Use Migrate Mate to filter actively sponsoring Scientist roles
Not every open Scientist listing at ByteDance comes with confirmed sponsorship intent. Use Migrate Mate to filter specifically for ByteDance Scientist roles verified for H-1B, E-3, or Green Card sponsorship so you're not wasting application cycles on positions that won't support your visa.
Understand PERM timing if a Green Card is your goal
ByteDance sponsors EB-2 and EB-3 Green Cards for Scientists, but PERM labor certification typically begins after one to two years of employment. Ask during the offer stage whether your role is eligible for sponsorship and what the expected internal timeline looks like.
Frequently Asked Questions
Does ByteDance sponsor H-1B visas for Scientists?
Yes, ByteDance sponsors H-1B visas for Scientist roles and has a consistent track record of doing so across research and applied science functions. Sponsorship covers both cap-subject H-1B petitions filed in April and, where applicable, cap-exempt filings. Confirm sponsorship availability for a specific role during the recruiter screen, as not every open listing is guaranteed to include it.
Which visa types does ByteDance commonly use for Scientist roles?
ByteDance sponsors H-1B, H-1B1 visa, and E-3 visas for Scientists at the nonimmigrant level, along with EB-2 and EB-3 employment-based Green Cards for longer-term permanent residence. Australian citizens are eligible for the E-3, which has no lottery and is typically faster to obtain than the H-1B. H-1B1 is available to nationals of Chile and Singapore.
What qualifications does ByteDance expect for Scientist roles?
Most Scientist postings at ByteDance require at minimum a Master's degree in computer science, machine learning, statistics, or a closely related field, with a PhD preferred for research-track roles. Strong publication records, experience with large-scale model training, and proficiency in Python or C++ are standard expectations. Applied Scientist roles weigh production system experience alongside research output.
How do I apply for Scientist jobs at ByteDance?
You can apply directly through ByteDance's careers portal or browse verified sponsoring Scientist roles through Migrate Mate, which filters specifically for positions where ByteDance has confirmed visa sponsorship. The process typically involves an initial recruiter screen, a technical phone round, and an on-site or virtual loop covering algorithms, system design, and a research presentation before an offer is extended.
How do I plan my timeline if I need H-1B sponsorship for a ByteDance Scientist role?
If you need a cap-subject H-1B, ByteDance must register you in the USCIS lottery, which opens in March for an October 1 start date. That means securing an offer several months before March. If you're on OPT or STEM OPT, you may be able to start before the H-1B takes effect. Ask ByteDance's recruiting team about their internal filing deadlines to avoid missing the registration window.
