For permanent residency, Microsoft typically supports EB-2 or EB-3 Green Card sponsorship after an initial period in role.
What qualifications does Microsoft expect for ML Research Engineer roles?
Most ML Research Engineer positions at Microsoft require a master's or PhD in computer science, machine learning, statistics, or a closely related field. Hands-on experience with large-scale model training, familiarity with frameworks like PyTorch or JAX, and a track record of research output, such as published papers or significant open-source contributions, are standard expectations across these postings.
How do I apply for ML Research Engineer jobs at Microsoft?
You can find and filter ML Research Engineer roles at Microsoft on Migrate Mate, which surfaces positions by visa type so you can confirm sponsorship before applying. Once you identify a role, applications go through Microsoft's careers portal. The interview process typically involves multiple rounds covering system design, coding, and a research presentation or deep-dive on prior work.
How do I plan my timeline if I need H-1B sponsorship for a Microsoft role?
H-1B cap registration runs each March, with a lottery selection shortly after and an October 1 start date. If you're finishing a degree on OPT, confirm your OPT expiration date against this timeline. STEM OPT extensions give you up to 36 months of work authorization, which can bridge a full cap cycle if needed. Discuss timing constraints with your Microsoft recruiter early so the team can plan around your status.
