Join LoopTech, Cook Medical’s applied AI team, to help turn promising artificial intelligence concepts into working products. LoopTech is a small, high-autonomy group inside Cook Medical that designs, prototypes, and ships AI applications across the company — from conversational platforms and internal tools to medical imaging pipelines. As a LoopTech intern, you will write real code from week one, using modern agentic development tools to move from concept to shipped demo quickly, and you will see your work used by real people inside the organization.
The primary objective of the LoopTech Intern is to gain practical experience by contributing to LoopTech’s active product portfolio: designing and shipping full-stack features, supporting data science and model evaluation work, documenting and demoing work clearly, collaborating effectively with engineers and researchers, contributing to responsible AI practices, building a professional network, and working toward a capstone project presented at the end of the internship.
- Design, build, and ship full-stack features on active LoopTech products, typically with Python (FastAPI) backends and TypeScript/React frontends.
- Use agentic development tools (e.g., Claude Code and similar AI coding assistants) and strong prompt engineering to accelerate development and reduce boilerplate.
- Conduct data collection, preparation, and curation in support of model training, evaluation, and analytics.
- Assist in building and running evaluation harnesses for AI models and agents, including error analysis and reporting of results.
- Lead and participate in rapid prototyping sessions to develop proof-of-concepts that could actually be used by the company.
- Package work as minimal, runnable demos that others can execute, and present working software at team demos and the capstone presentation.
- Document your approach and share your work with the organization.
- Participate in team discussions, brainstorming sessions, knowledge sharing, user experiments, and pilot projects.
- Strong programming skills in Python and/or TypeScript/JavaScript, with working git fluency.
- Familiarity with web application fundamentals: APIs, databases, and modern frontend frameworks.
- Interest in large language models and applied AI; experience with AI coding assistants or agentic tools is a plus.
- Familiarity with machine learning concepts, data preprocessing, or frameworks such as PyTorch is a strong plus but not required.
- Motivated self-starter with excellent problem-solving skills and the ability to work with high autonomy as well as in a team.
- Eagerness to learn, adapt, and take on new challenges in the AI field.
- Strong communication skills and the ability to convey complex technical concepts to non-technical audiences.
- All candidates should have an interest in a career in the Life Sciences field, a willingness to take initiative, and an ability to work well with others
- Candidates should be students entering their Junior or Senior year the following fall semester or entering graduate school; candidates who graduate the spring semester before this internship are also eligible
- A minimum GPA of 3.0 is preferred
- All candidates must provide proof of enrollment (including pre-registration certification for the following fall) for consideration
- Multiple disciplines will be considered (e.g. Computer Science, Data Science, Informatics, Software Engineering, Computer/Electrical Engineering, and related fields)

Tips for Your Full Stack Engineer Internship Search
Apply earlier than you think you need to
Large employers open summer internship applications the preceding fall, sometimes in August or September. Smaller companies and co-op programs post much closer to start dates, so roles appear year-round. Check listings regularly and submit applications for structured programs as soon as they open.
Build projects that give recruiters something to assess
Without a long work history, your GitHub repositories, deployed applications, and course projects are the proof that gets you screened in. Full stack engineer intern candidates stand out with two or three complete projects that show both front-end and back-end work, linked directly from your resume.
Work campus channels and direct applications together
Campus career fairs surface structured programs tied to your university, and career center staff often know which employers recruit from your school before roles post publicly. Apply directly to companies running smaller cohorts at the same time, since many full stack engineer internships never appear at campus events.
Practice coding screens out loud before your first application
Full stack engineer intern interviews typically include a coding screen focused on data structures and algorithms. Practice explaining your reasoning as you work through problems, not just arriving at the answer, since interviewers weigh your thinking process as much as the solution. Run through problems verbally, not just silently on paper.
Target structured internship programs built for new engineers
Many large technology and financial services companies run cohort-based software engineering internship programs designed to train people who are new to the field. These programs recruit early in the fall, fill fast, and offer structured mentorship and real project work. Identify the ones that fit your background and apply in the first wave.
Set your work-type filter before you start
On-site roles are 35% of the full stack engineer internships listed here. Decide what you can actually commit to before you start applying, then filter by location and work type on Migrate Mate so you are not sorting through roles you cannot take.
Full Stack Engineer Internships: Frequently Asked Questions
How do I get a full stack engineer internship?
Lead with coursework and personal projects rather than work history, since hiring teams expect limited experience at the intern level. A linked GitHub repository or deployed project gives recruiters something concrete to assess your skills. Combine direct applications with campus career fairs, where recruiters often move faster for students they meet in person.
Can a full stack engineer internship turn into a full-time job?
Many employers extend return offers to strong interns, but conversion is never guaranteed. For full stack engineer interns, what actually drives it is the quality of your contributions to real features, available headcount on the team, and return-offer timing relative to recruiting cycles. Position for one by delivering solid work, but keep applying elsewhere so you are not depending on it.
When should I apply for full stack engineer internships?
Earlier than most candidates expect. Large employers recruit summer interns the preceding fall, sometimes opening applications in August or September for programs that start the following May. Smaller companies and co-op programs post much closer to their start dates, so openings appear year-round and checking regularly pays off regardless of the season.
Are full stack engineer internships paid?
Most professional full stack engineer internships in the U.S. are paid. Compensation varies by company size, industry, and location, and listings show it where the employer discloses it. Stipend-based or academic credit arrangements exist at some nonprofits and startups, so read each listing carefully to understand what is being offered.
What should a full stack engineer internship resume include?
Lead with projects, not work history. Include two or three complete, documented projects that show the full stack, naming the languages, frameworks, and tools you used and linking to the GitHub repository or live deployment so reviewers can see the work directly. Add relevant coursework, keep everything to one page, and skip anything that does not show you can build.
Are there remote full stack engineer internships?
Yes. Remote and hybrid roles make up 65% of the full stack engineer internship listings here, with the rest on-site. Remote cohorts fill fast because they attract applicants from anywhere, so apply early and filter by work type to see them before they close.
Can international students get full stack engineer internships?
Yes. F-1 students can intern through CPT while enrolled or through OPT work authorization after finishing a degree, and the employer does not have to file anything for either, so many companies are open to international interns. Confirm your eligibility and timing with your university's international student office before accepting an offer.
