Synthesia Internship 2027–2028: How to Get In Without a Formal Program

Last updated: July 2026

Synthesia does not run a formal internship program. The $4 billion AI video platform, whose avatars are used by over 90% of the Fortune 100, employs 900 people and focuses almost exclusively on experienced hires. There are no intern listings on their Ashby job board, no university recruiting pipeline, and no structured summer cohort as of July 2026. But internships have happened on an ad-hoc basis, and a 2025 Reddit thread confirms that cold-emailing about intern openings is a viable path in. The challenge is not surviving the interview. It is getting one.

Quick Facts

One number frames the challenge: zero. As of July 2026, Synthesia has zero intern-titled positions listed. The company fills its 900-person roster with experienced hires and creates intern openings only when a specific team identifies a project need. Cold outreach, academic connections to the founders' universities (Stanford, Cambridge, UCL, TUM), and employee referrals are the realistic pathways in.

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 and data-analysis evidence a cold email to Synthesia needs to carry. Explore all Externships.

What Is a Synthesia Internship?

A Synthesia internship, when it exists, is an ad-hoc placement at the world's leading AI video generation platform. The company's technology creates photorealistic AI avatars that speak in over 140 languages, and its client list reads like a Fortune 100 directory: Amazon, Zoom, Microsoft, Heineken. Founded by researchers from Stanford, Cambridge, UCL, and the Technical University of Munich, Synthesia has raised approximately $536 million from Google Ventures, Accel, NEA, and Sequoia. There is no structured intern cohort, no rotation, and no guaranteed slot. Instead, teams occasionally create intern roles when a specific project warrants it, and the company's culture of shipping meaningful features every few days means interns are expected to contribute production-level work immediately. The trade-off for the lack of structure is direct access to a world-class ML engineering team working on generative video, avatar synthesis, and diffusion models at commercial scale.

When Do Synthesia Internship Applications Open for 2027–2028?

Synthesia does not run a structured internship recruiting cycle, so there are no confirmed deadlines or application windows. The timeline below is estimated from UK tech startup norms, the company's 26-day average hiring speed, and the absence of any formal intern program. Any intern openings are created ad-hoc based on team needs and filled on a rolling basis. The critical insight: cold outreach and networking are the primary pathways, not a job-board application. Begin building connections in Q4 2026 and monitor the Ashby board weekly starting January 2027.

Why You Must Apply the Week Applications Open

Synthesia does not run a structured intern cycle, which means there is no deadline to beat. But the absence of structure is itself the challenge. Any intern openings are created when a specific team identifies a project need, filled through the Ashby ATS, and closed as soon as the right candidate appears. Glassdoor data shows 49% of interviews come from online applications, 27% from recruiters, and 16% from employee referrals. The move is to start cold outreach in Q4 2026, target engineering managers or the People team with a personalized email referencing specific Synthesia technology, and monitor the Ashby board weekly starting January 2027. When a relevant posting appears, apply within 24 hours. The 26-day average from application to offer means the window is narrow.

Which Synthesia Internship Programs Should You Target?

Synthesia does not have named internship tracks. The following are possible placements based on the company's active teams, hiring patterns, and core product areas. Any intern role would be created ad-hoc to fill a specific team need, so the actual track depends on what is available when you apply or what your cold outreach convinces a team to create.

Monitor the Synthesia Ashby job board for any junior or intern-titled openings. The company's rapid growth to 900+ employees suggests new teams and roles are being created regularly. Also check the careers page for new team announcements.

What Are the Eligibility Requirements?

Since Synthesia does not run a formal intern program, there are no published eligibility requirements. The following is inferred from the company's hiring patterns, interview data, and team composition:

• Degree level: pursuing a BSc, MSc, or PhD in Computer Science, Machine Learning, Computer Vision, or a related field. PhD candidates and those with published research at NeurIPS, ICML, CVPR, or ICCV have a significant advantage for ML tracks.

• Technical baseline: strong Python skills and familiarity with PyTorch or TensorFlow. Understanding of deep learning fundamentals including CNNs, GANs, diffusion models, and transformers.

• Work authorization: Synthesia Limited is a registered UK visa sponsor. The CEO has stated roughly 80% of London HQ staff are immigrants. UK Tier 5 (Government Authorised Exchange) visa may apply for interns. No confirmed data on US intern visa sponsorship.

• Culture fit: the company emphasizes ownership and speed, describing its engineering culture as one where people deliver meaningful features every few days. Demonstrated builder mentality and open-source ML contributions are valued.

• Non-technical tracks: Customer Success and Sales roles in New York and Austin may be accessible to business, communications, or analytics students without deep ML backgrounds.

Can I Get a Synthesia Internship Without Published Research?

For ML and research engineering tracks, published papers are a significant advantage given that the founders are researchers from Stanford, Cambridge, UCL, and TUM. However, the company's 73% positive interview rating and emphasis on practical problem-solving suggest that strong portfolio projects, open-source contributions, and demonstrated ability to ship working ML systems can compensate. For non-engineering tracks (Customer Success, Sales, Design), the bar is lower and more focused on communication, product knowledge, and relevant experience. The real barrier is not the qualification threshold but the absence of a formal program, which means you must convince a team that creating an intern role for you is worth their time.

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

Read across Synthesia's Glassdoor interview reports and active engineering job descriptions, and the pattern tracks the product. Python and deep learning frameworks appear in every technical role. Computer vision and video generation are core to the company's avatar technology. And the interview process for ML roles emphasizes practical problem-solving over algorithmic puzzles, with a timed take-home assignment replacing LeetCode-style coding. But the skill that separates candidates at Synthesia is cross-functional ownership. With 900 employees serving 90% of the Fortune 100, the engineering culture demands people who ship quickly and communicate clearly across teams.

Build These Skills Before You Apply

And every skill in that chart maps to a remote Externship where you finish a real project before a cold email lands.

How close is the overlap? The Wayfair project involves agent-engineering work that exercises the same build-ship-evaluate cycle Synthesia's take-home assignment tests, and the Beats project produces the data-analysis deliverable a cold email to an engineering manager needs to carry.

What Is the Synthesia Application and Interview Process Like?

Since Synthesia does not run a formal internship program, the application process has two phases: getting noticed and then clearing the standard interview loop. The interview itself averages 26 days and is rated 73% positive on Glassdoor:

1. Research and cold outreach. Study Synthesia's product, technology, and recent developments. Craft a personalized cold email to engineering managers or the People team referencing specific Synthesia technology that interests you. Attach a brief portfolio or link to relevant projects and publications. A Reddit thread from 2025 confirms cold emails about intern openings are a viable path.

2. Monitor and apply. Check jobs.ashbyhq.com/synthesia weekly starting January 2027. Apply immediately when any junior or intern-titled role appears. Also check synthesia.io/careers. Seek employee referrals where possible; 16% of Glassdoor interviews come through referrals.

3. Recruiter and hiring manager screens. A phone screen covering logistics, background, and role fit, followed by a one-on-one with the hiring manager focused on technical background, motivation, and team fit. Expect behavioral questions: 'What drives you?' and 'Describe how you align in cross-functional work.'

4. Technical round. For ML roles, a timed take-home assignment of approximately 8 hours focused on ML fundamentals, practical problem-solving, and system design. No LeetCode-style coding has been reported. Non-engineering roles may have a conversational technical discussion or presentation instead.

5. Team and culture fit, then offer. A final round with a panel or one-on-one interview covering values, cross-functional alignment, and personal motivation. Offers arrive within approximately 26 days of the initial application.

Two skills to drill are clear: practical ML fluency for the take-home (be ready for an 8-hour deep-dive into a real-world ML problem, not toy puzzles) and a compelling cold-outreach narrative (why does your work connect to Synthesia's avatar and video-generation technology?). The 73% positive interview rating suggests a well-organized process once you are in it. The challenge is getting to the front door.

What Students on Reddit Say

Four community threads provide context on working at and applying to Synthesia, all paraphrased.

How Do You Stand Out When There Is No Application?

Three moves, all before a posting exists. First, write a cold email that earns a response: reference specific Synthesia technology (avatar synthesis, diffusion-model video generation, the 140-language pipeline), attach a portfolio of relevant ML work, and explain concretely what you could build during a 12-week placement. A generic 'I am interested in AI' message will not survive the inbox of an engineering manager at a 900-person company. Second, leverage academic networks. The founders come from Stanford, Cambridge, UCL, and TUM, and university career services or professor connections at these institutions can open doors that cold email cannot. Third, bring finished artifacts. Synthesia's culture is about shipping features fast, so a completed Externship, an open-source contribution, or a published paper on generative video or computer vision gives you evidence of output speed, not just interest. The company's 16% referral rate on Glassdoor means that if you can connect with a current employee who vouches for your work, you skip the hardest part of the process entirely.
