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

Last updated: July 2026

Windsurf interns earned $54.81 per hour in Summer 2025, more than double the $22.70 industry average for software engineering interns. Then, in July 2025, Google paid roughly $2.4 billion to hire the co-founders and senior R&D staff into DeepMind, and Cognition AI acquired the remaining entity for $250 million. For the 2027–2028 cycle, any internship postings will flow through Cognition's careers page starting fall 2026. The product still ships, the pay is still top-tier, and the team still builds one of the most-used AI coding assistants in the world, but the org chart has changed. Here is what that means for your application.

Quick Facts

Windsurf delivered $54.81/hr intern compensation in 2025, placing it in the top tier of AI startup pay. The July 2025 acquisition by Cognition AI means future roles post through Cognition's Ashby board, not windsurf.com. No intern listings are live as of July 2026, but 78 full-time positions signal active hiring. Monitor the Cognition board from fall 2026 onward.

What Is a Windsurf Internship?

A Windsurf internship is a paid, full-time placement at one of the most prominent AI coding-assistant companies in the industry. Historically run under the Codeium and then Windsurf brand, interns worked directly on the AI-powered IDE, autocomplete engine, and Cascade automated codebase transformation features used by over one million developers and 4,000 enterprise customers including JPMorgan Chase, Dell, and Zillow. Following Cognition AI's acquisition in July 2025, the product continues to ship under a new parent company that also builds Devin, the autonomous AI software engineer. The team is described internally as extremely talent-dense, with world-class competitive programmers and alumni from Scale AI, Palantir, Cursor, Waymo, Tesla, and Google DeepMind. Glassdoor rates career opportunities at 4.6 out of 5, and the $54.81-per-hour intern pay sits well above the industry median. Prospective interns should note the corporate transition: both co-founders departed for Google DeepMind, and future internship programs will be managed by Cognition under interim CEO Jeff Wang.

When Do Windsurf Internship Applications Open for 2027–2028?

Windsurf's internship timeline is harder to predict than most because the company changed hands in mid-2025. Historically, Codeium/Windsurf posted intern listings in the fall semester for the following spring or summer. The average time to hire for software engineering roles was 16 days. Under Cognition AI, the hiring calendar is not yet established, but with 78 full-time positions open as of July 2026, the recruiting infrastructure is active. The safest assumption is that any summer 2027 intern postings will appear on the Cognition Ashby board between September and November 2026. Since the program historically ran small cohorts with rolling fills, the window between posting and closure could be narrow.

Why You Must Apply the Week Applications Open

Windsurf historically ran a small, informal intern program that filled positions as matches were found. That rolling, first-come dynamic means the posting-to-closure window could be a matter of weeks, not months. With the transition to Cognition, the structure may formalize, but the hiring velocity is already there: 78 full-time roles are open, and the average SWE time-to-hire is just 16 days. So set a weekly calendar reminder to check the Cognition Ashby board starting September 2026, and have your resume, portfolio, and Python fundamentals ready to submit the day a posting appears. At a company this small, a referral from a current employee can cut the process from five weeks to two or three.

Which Windsurf Internship Programs Should You Target?

Windsurf historically confirmed only one intern track: Software Engineering. Under Cognition AI, the full-time hiring spans Customer Engineering, Research and Development, Sales, Marketing, and General and Administrative functions. Three additional intern tracks are projected below based on Cognition's current full-time role categories. Only the first has been confirmed through historical data.

Check the Cognition Ashby board for the latest openings. Note that projected tracks are based on full-time role categories and may not materialize as intern programs. The strongest signal for future intern tracks is where Cognition is hiring the most full-time engineers.

What Are the Eligibility Requirements?

Windsurf's historical intern listing and Cognition's current full-time requirements suggest the following eligibility profile:

• Enrollment: sophomore or junior undergraduate in Computer Science or a related field. Graduate students in ML/AI are also strong candidates for research-oriented tracks.

• Technical foundation: strong skills in data structures, algorithms, and Python. Familiarity with AI/ML concepts, distributed systems, and open-source software debugging is advantageous.

• Work authorization: not confirmed for interns. Full-time H-1B sponsorship is available at Cognition, so CPT/OPT support for interns is probable but not guaranteed.

• Location: primarily on-site. Cognition listings specify on-site or hybrid. Expect to be in San Francisco, Mountain View, Pittsburgh, Austin, or New York City.

Does Windsurf/Cognition Require Competitive Programming Experience?

No formal competitive programming requirement exists, but the team is described as having world-class competitive programmers, former founders, and leaders from Scale AI, Palantir, Cursor, Waymo, Tesla, and Google DeepMind. The interview difficulty is rated 3.7 out of 5 on Glassdoor, and one candidate noted they solved the problem but still did not pass, suggesting the bar extends beyond correct solutions to code quality, optimization, and communication. Competitive programming experience helps, but demonstrable AI/ML project work and open-source contributions carry equal weight.

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

Cross-referencing the confirmed Windsurf intern listing, Glassdoor interview reports, and five current Cognition full-time SWE and research engineering job descriptions reveals a clear hierarchy. Python and data structures dominate the technical bar, but AI/ML fluency is what separates Windsurf from a generic SWE internship. The interview process uniquely allows AI tools during the online assessment, which means the evaluation shifts toward how you think with AI rather than pure recall. Behavioral fit centers on startup adaptability and collaborative problem-solving under ambiguity.

Build These Skills Before You Apply

Every skill in that chart maps to a remote Externship where you finish a real project before a role opens.

The Wayfair project is agent-engineering work that produces the Python, AI, and system-design artifacts a Windsurf/Cognition technical interview probes for. The Beats project delivers the data-analysis and metrics evidence a behavioral round rewards.

What Is the Windsurf Application and Interview Process Like?

Based on one Glassdoor intern review and sixteen full-time SWE interview reports, the Windsurf/Cognition hiring funnel looks like this:

1. Monitor and apply on jobs.ashbyhq.com/cognition. The legacy windsurf.com/careers page redirects here. Submit your resume with a portfolio of Python and AI/ML projects. A referral from a current employee can cut the process timeline from five weeks to two or three.

2. Online assessment with AI tools allowed (duration unconfirmed). A coding assessment where you can use any AI tool. The focus is algorithmic problem-solving, but the AI-allowed policy shifts evaluation toward how you leverage tools to think, debug, and optimize rather than pure memorization.

3. Two technical interviews (medium to medium-hard). Data structures and algorithms questions at LeetCode medium to medium-hard difficulty. One candidate noted they solved the problem but still did not advance, suggesting the bar extends to code quality, edge-case handling, and communication of thought process.

4. Behavioral interview. Standard questions including self-introduction, motivation for joining Windsurf/Cognition, and group problem-solving scenarios. The intern-specific round was reported as straightforward, with questions like describing how you navigated a problem in a team setting.

5. Offer. Average time to hire is 16 days for SWE roles and 23 days company-wide. Some candidates also received a take-home coding project or a debugging round on an open-source library before the offer stage.

The two things to drill before the posting goes live: Python fluency for the AI-allowed OA (practice with and without AI tools so you can demonstrate judgment, not just output), and LeetCode medium problems on arrays, trees, graphs, and dynamic programming for the technical rounds. Prepare four to six behavioral stories that show ownership and adaptability in fast-paced, ambiguous environments. Half of interviewed candidates found the job through recruiter outreach, so keeping a polished LinkedIn and GitHub profile increases your chances of being contacted directly.

How Do You Stand Out at a Company in Transition?

Three moves specific to the Windsurf/Cognition situation. First, demonstrate you understand the product and the corporate context: interviewers at a post-acquisition startup respect candidates who have actually used the Windsurf IDE, can articulate what Cascade does, and understand how Cognition's Devin product complements the stack. Download it, build something, and talk about it. Second, optimize for the AI-allowed OA: this is not a standard coding test. Practice solving LeetCode problems both with and without AI tools so you can show judgment in tool selection, not just raw output. Third, bring evidence of ownership in ambiguous environments: Windsurf went through three name changes and an acquisition in four years, so the behavioral round will favor candidates who thrive in fast-moving, uncertain contexts. A completed remote Externship project where you shipped real work with minimal hand-holding is exactly that evidence.
