AI21 Labs Internship 2027–2028: Programs, Deadlines & How to Apply

Last updated: July 2026

AI21 Labs raised $155 million in its Series C led by Google and Nvidia, reaching a $1.4 billion valuation, and was co-founded by Prof. Amnon Shashua, the same researcher behind Mobileye (acquired by Intel for $15.3 billion). The company has since pivoted from its Jamba LLM and Wordtune products to Maestro, an AI-agent orchestration platform, while reports of a $2 to $3 billion Nvidia acqui-hire surfaced in late 2025. For the 2027 to 2028 cycle, internship availability is uncertain, but the research caliber and publication opportunities remain among the strongest in the Israeli AI ecosystem.

Quick Facts

AI21 Labs sits at a crossroads: a $1.4 billion valuation, publications at NeurIPS and ICML, and co-founders from Mobileye and Stanford, but also a 61% workforce reduction in mid-2025 and a potential Nvidia acquisition that could reshape the entire program. Research intern slots, when available, are few and PhD-preferred.

Externships are short, remote projects where you finish real work for a real company. The Wayfair AI Agent Engineering Externship and Beats by Dre Data Analytics Externship build the ML engineering, data analysis, and agent orchestration skills that AI21 Labs' research and product interviews test.

What Is an AI21 Labs Internship?

An AI21 Labs internship places students inside one of the most research-intensive NLP labs outside the United States, co-founded by Prof. Amnon Shashua (Mobileye) and Prof. Yoav Shoham (Stanford, Google). The company has published at NeurIPS, ICML, ICLR, and ACL, and its intern alumni have contributed to publication-quality research alongside senior scientists holding advanced degrees. Unlike US-centric programs at OpenAI or Anthropic, AI21 offers a distinctive path through the Masa Israel program, which provides visa support, cultural programming, and structured placements for international candidates in Tel Aviv. The company's current strategic focus is Maestro, an AI-agent orchestration platform that claims up to 50% improvement in LLM accuracy for enterprise workflows. With the potential Nvidia acqui-hire at $2 to $3 billion reported in late 2025, the program's future structure is uncertain, but the research experience and NLP expertise it builds remain highly portable across the AI industry.

When Do AI21 Labs Internship Applications Open for 2027–2028?

AI21 Labs does not publish a fixed recruiting calendar. Israeli AI startups typically post internship roles two to four months before the intended start date, and AI21's Masa Israel pathway operates on rolling admissions year-round. For the Summer 2027 cycle, expect postings between February and April 2027 if the company is actively hiring. The full interview process runs approximately three weeks across five rounds. The critical context: AI21 cut roughly 61% of its workforce in mid-2025 and its careers page returned a 404 as of July 2026, so candidates should confirm the company's hiring status before investing preparation time. If the reported Nvidia acquisition closes, internships would likely be restructured under Nvidia's established program.

Why You Must Apply the Week Applications Open

AI21 Labs reviews applications on a rolling basis, and the company is small enough that a single strong candidate can fill the only open slot before a posting is widely circulated. The Masa Israel pathway adds a second channel, also rolling, which many candidates overlook entirely. The practical move: set alerts on LinkedIn and the Masa Israel portal now, and apply within the first week of any posting. At a company with roughly 70 developers after the 2025 layoffs, there may be one or two research intern seats per cycle, and those fill through networks as much as through portals. If you have a connection in the Israeli AI community or at a university with ties to the Hebrew University or Technion, a warm introduction carries outsized weight. And note the Nvidia factor: if the acqui-hire closes, the seats may shift to Nvidia's own internship pipeline, which has its own timeline and application cadence.

Which AI21 Labs Internship Programs Should You Target?

AI21 Labs has historically offered internships through two channels: direct placements at its Tel Aviv headquarters and structured positions through the Masa Israel program for international candidates. The company's pivot to Maestro (AI-agent orchestration) has shifted the technical focus, but the core research culture remains rooted in its NLP and LLM heritage.

Check LinkedIn and the Masa Israel portal for current availability. The ML Research Intern track is the most competitive and most likely to produce a publishable research outcome.

What Are the Eligibility Requirements?

AI21 Labs' academic-first culture sets its eligibility bar higher than most industry internships, particularly for research roles:

• Education: pursuing or recently completed MS or PhD in Computer Science, Machine Learning, NLP, or a related field. PhD candidates are strongly preferred for research roles. Undergraduate students may find opportunities through the Masa Israel program for non-research tracks.

• Research output: publications at top AI/NLP venues (NeurIPS, ICML, ICLR, ACL, EMNLP) are a strong differentiator. AI21 explicitly values and expects publication-quality research output from interns.

• Technical skills: strong Python, experience with PyTorch or JAX, and solid understanding of deep learning fundamentals including Transformer architectures, attention mechanisms, and optimization.

• Visa pathways: international candidates can apply through the Masa Israel program (B-1 work visa for Tel Aviv). For the NYC office, J-1 visas or CPT/OPT are options. Arrangements may change if the Nvidia acquisition closes.

Does AI21 Labs Prefer PhD Candidates Over Master's Students?

Yes, for research roles. AI21 was founded by two professors (Shashua from Hebrew University and Mobileye, Shoham from Stanford) and most employees hold advanced academic degrees. The company's publication record at NeurIPS and ICML reflects a research lab culture where PhD-level depth is the norm, not the exception. Master's students with strong research experience and publications can compete, but undergraduates are typically steered toward the Masa Israel sales track or engineering roles rather than core research positions.

What Skills Does AI21 Labs Look For, and How Do You Build Them?

No active AI21 Labs job descriptions were accessible during research, as the careers page returned a 404. The skills below are inferred from the company's publication record, Glassdoor interview data, Masa Israel listings, and the Maestro platform focus. Across research and engineering roles, Python and deep learning frameworks appear universally, NLP and LLM expertise in four of five role categories, and agent orchestration skills (reflecting the Maestro pivot) in three. The interview process includes a take-home assignment that simulates real project work, so applied ML fluency matters as much as theoretical depth.

How Is Demand for ML Research Interns Moving Right Now?

Build These Skills Before You Apply

The NLP and agent orchestration skills AI21 tests map directly to remote Externships where you finish a real project before any role opens.

The Wayfair project is agent-engineering work that yields the build-and-present evidence AI21's take-home and panel interview rounds probe for, and the Beats project ends with the data-analysis story a research discussion wants to hear.

What Is the AI21 Labs Application and Interview Process Like?

AI21 Labs' interview process typically runs five rounds over approximately three weeks, based on Glassdoor data:

1. Apply online or through Masa Israel. Monitor LinkedIn and the Masa Israel portal. For research roles, emphasize publications and research experience in your CV. International candidates should explore the Masa Israel pathway for visa support.

2. Recruiter screen (30 minutes). Initial phone or video call with HR to discuss background, motivation, and logistics. Standard format to confirm mutual interest before investing in technical rounds.

3. Hiring manager interview (45 to 60 minutes). Discussion of background, research experience, and role fit with the team lead. For ML Research Intern roles, expect a deep dive into your publications and research methodology.

4. Take-home assignment (variable duration). A technical project simulating real work at AI21. For research roles, this likely takes the form of a research-oriented coding project or paper analysis rather than a timed online assessment. Results are presented in the next round.

5. Panel interview (60 minutes). Present and discuss your take-home assignment results with team members. Expect follow-up questions probing your approach, trade-offs, and potential extensions.

6. Final interview and culture fit (45 to 60 minutes). Meeting with senior leadership or cross-functional team members. AI21's academic founder culture values intellectual curiosity and collaborative research ability.

The take-home assignment is the differentiating step. Unlike companies that rely on timed LeetCode assessments, AI21 tests whether you can execute a realistic research or engineering task and then defend your decisions in front of a panel. Prepare by practicing end-to-end ML project presentations: problem framing, methodology, results, and limitations. The process is professional and structured, with an overall positive candidate experience reported on Glassdoor despite the length.

What Students on Reddit Say

Direct Reddit discussion of AI21 Labs internships is limited, but several threads reveal the company's technical reputation and current direction, all paraphrased.

How Do You Stand Out at a Research Lab Where PhD Is the Norm?

Three moves, all before a role opens. First, publish or perish: AI21's academic-first culture means a paper at NeurIPS, ICML, or ACL carries more weight than a year of industry experience. If you do not have a publication, a strong preprint on arXiv with reproducible code is the next best signal. Second, build agent orchestration fluency: AI21's pivot to Maestro means current interns would work on multi-agent systems, not standalone LLMs, so a project demonstrating agent coordination, tool use, or workflow automation puts you in the right conversation. Third, explore the Masa Israel pathway early: this structured program provides visa support, cultural programming, and a direct placement channel that most international candidates overlook entirely. It is not a backup plan; it is a legitimate application route that sidesteps the standard portal. And note the Nvidia factor: if the acqui-hire closes, your AI21 preparation translates directly to Nvidia's research internship pipeline, which is one of the largest in the industry.
