Are you interested in joining us for an internship next year? That’s amazing! We have not yet finalized recruitment for the Summer of 2026, but you can express interest here to join our Colossal Summer Internship Talent Community!
Please note: We host a very small number of interns each year. We will respond to your application if/when an appropriate internship opportunity becomes available. Updates on your application may not come through until December at the earliest.
Applications for a summer 2026 internship with Colossal will close on Friday, March 6th.
**We do not have any internship or co-op opportunities available for the fall or winter. This is for the summer of 2026 only**
- Internships that become available for Summer 2026 will either be selected from this posting or a separate individual posting on our Careers website posted sometime between December 2025-March 2026.
- We do not typically begin interviewing for internships until December or January.
- Interns would ideally start with us sometime in June and finish sometime in August.
- Internships with Colossal will be based on-site in Dallas, TX. We do not provide any housing.
- To qualify, you must be a current university student in the United States that has completed at least 1 year of undergraduate studies.
- Students that have already graduated prior to 2026 or will be graduating in 2026 are not eligible for internships but may apply to full-time job postings.
- US work authorization is required without the need for company assistance in securing a visa.
As internship opportunities open up, we may reach out to you. Otherwise the only communication you will receive is confirmation that we received your application. Once all internship decisions have been made, a final update will go out.
In the meantime, keep an eye on our Careers Website for potential specific Internship postings.
