Internship Small Startup information

What are the key skills and qualifications needed to thrive as an intern at a small startup, and why are they important?

To thrive as an intern at a small startup, you typically need a foundational knowledge in your field of study, strong problem-solving abilities, and a willingness to learn quickly, often supported by current or recent enrollment in a relevant academic program. Familiarity with productivity tools like Google Workspace, project management software like Trello or Asana, and basic data analysis platforms is often advantageous. Strong communication, adaptability, and initiative are crucial soft skills, as startup environments demand flexibility and proactive contributions. These skills and qualities are important because interns at startups often wear many hats and must be able to handle evolving responsibilities in a dynamic, fast-paced setting.

What can I expect in terms of mentorship and learning opportunities during an internship at a small startup?

Interning at a small startup typically offers hands-on experience and close collaboration with founders and core team members. You can expect a less hierarchical structure, which means you'll likely have direct access to senior staff and more opportunities to ask questions, receive feedback, and contribute ideas. Startups often foster a culture of learning by doing, so you'll be given meaningful responsibilities and the chance to see the impact of your work. However, structured mentorship programs may be less formal compared to larger companies, so it's important to be proactive about seeking guidance and support.

What is an internship at a small startup?

An internship at a small startup is a temporary position where students or recent graduates gain hands-on experience by working closely with a small, entrepreneurial company. Unlike larger corporations, small startups often provide interns with opportunities to take on more responsibility, learn directly from founders, and contribute to various aspects of the business. This experience can be highly valuable for developing a broad skill set, networking, and understanding the unique challenges and rewards of startup environments.

Job description

At Capstan Medical, we're building one of the most exciting and innovative companies in medtech-developing a first-of-its-kind robotic platform for minimally invasive heart valve treatment. Our team combines surgical robotics, catheter-based delivery, and next-generation implants to transform complex procedures into safer, lower-stress solutions for patients and clinicians alike. As a highly collaborative, hands-on team, we move fast, wear multiple hats, and believe the best ideas can come from anyone.
Based in Santa Cruz, our unique workspace blends cutting-edge Bay Area innovation with a lifestyle-driven environment near trails, beaches, and open space-creating the perfect place to do meaningful, career-defining work.

platform, and learn first hand what medical device development is like.

team to clearly understand the problem, develop appropriate solutions, and ensure project
completion before your internship ends.
• Help out with a variety of smaller projects on an as needed basis, pitch in to fill the gaps and gain
experience with a large variety of development activities supporting the team's goal of bringing
our device to clinical trial.

Skills:
• Experience designing, building, and troubleshooting mechanical systems, preferably
electromechanical systems.
• Familiarity with using CAD (SolidWorks preferred) for creating detailed parts, assemblies, and
drawings for manufacturing. Familiarity with using GD&T as a bonus.
• Strong communication skills. Ability to communicate clearly and consistently about your work,
and to seek feedback and ask for help as appropriate.
• Ability to organize ones own day to day work and proprieties, ability to develop and execute
simple project plans is preferred.
Requirements:
• Pursuing a degree in Mechanical Engineering or related engineering discipline.
• Experience working on project teams, preference for experience outside of standard coursework.
• Comfortable working with high levels of ambiguity and an ability to convert that into tangible
outcomes
