About The Position

As a Software Engineering Intern at Triumph, you'll be embedded within our engineering team and contribute directly to the codebase from week one. We're looking for curious, scrappy, and thoughtful engineers who want to learn fast and ship real work. We don't expect you to know everything. We expect you to ask good questions, take feedback well, and bring energy to the team. By applying to this role, you will be considered for multiple intern roles open across our various engineering teams. Please only apply once. Internships are 12 weeks paid and full-time for either the summer or fall of 2026 (indicate your preference on our application). Our internships will be located at Triumph’s headquarters at Levi’s Plaza in San Francisco. The team is in the office 5 days a week.

Currently enrolled in a Bachelor's or Master's degree program in Computer Science, Software Engineering, or a related technical field, with an expected graduation date between August 2026 and June 2028.
Proficiency in at least one modern programming language relevant to your track (e.g., JavaScript/TypeScript, Go, Swift).
Foundational understanding of data structures, algorithms, and software design principles.
Experience building at least one project beyond coursework. This could be a personal project, hackathon submission, open-source contribution, or previous internship.
Strong written and verbal communication skills, with the ability to explain technical decisions clearly.
Comfort working in a fast-paced, collaborative environment where priorities can shift.

Write clean, tested, and well-documented code that other engineers can confidently build on.
Debug real issues in real systems and learn how production software is operated, monitored, and improved.
Present your work at the end of the summer to the broader engineering team.
