Typescript Intern information

What does a Typescript Intern do?

A Typescript Intern assists in developing and maintaining software applications using the TypeScript programming language, which is a superset of JavaScript. They usually work under the guidance of experienced developers to write, test, and debug code, help with documentation, and learn best practices in software development. Interns may also participate in code reviews, contribute to team meetings, and gain experience with modern development tools and workflows. This role is ideal for students or recent graduates looking to build practical skills in web development and software engineering.

What types of projects and responsibilities can a TypeScript Intern expect during their internship?

As a TypeScript Intern, you can expect to work on a range of tasks, such as developing new features, fixing bugs, and writing unit tests within existing web or software applications using TypeScript. You will likely collaborate closely with senior developers, participate in code reviews, and contribute to team meetings. Interns often get the chance to work on both front-end and back-end code, gaining exposure to industry-standard development workflows and tools. This hands-on experience is designed to strengthen your coding skills and understanding of scalable, maintainable codebases.

What are the key skills and qualifications needed to thrive as a Typescript Intern, and why are they important?

To thrive as a Typescript Intern, you need a solid foundation in JavaScript, TypeScript, and basic software development principles, often supported by coursework or personal projects. Familiarity with code editors like VS Code, version control systems such as Git, and basic knowledge of frameworks like React or Node.js is typical. Strong problem-solving abilities, eagerness to learn, and effective communication help you adapt and collaborate within a development team. These skills and qualities are crucial for contributing to projects, growing technically, and making a positive impact in a fast-paced tech environment.

Job description

About the Role

A fast-growing, pre-seed AI startup in the talent and recruiting space is looking for a Founding Engineer Intern to join their founding team in San Francisco. You'll work directly with the CTO to ship features daily and help build a fully agentic system that automates headhunting end-to-end. This role puts you at the center of rapid experimentation with real ownership and high-impact outcomes — including time in hacker-house environments in Latin America.

What You'll Do

  • Build and ship features daily alongside the CTO to automate the recruiting process end-to-end.

  • Own full end-to-end development — from ideation to production — for core product features.

  • Collaborate with the founding team to design and ship components of an agentic AI system.

  • Talk to users and measure impact on hiring speed to drive rapid iteration.

  • Thrive in a founder-paced, high-output environment with daily feedback loops.

What We're Looking For

Required:

  • At least 6 months of experience with React and TypeScript in a production environment.

  • Hands-on experience with Cursor, Supabase, Prisma, and Typesense in a production React/TypeScript stack.

  • Full-stack focus — not an ML engineer and not overly specialized in a single language (e.g. Python or C++).

  • Strong ownership mindset with the ability to drive features from ideation to production independently.

  • Currently enrolled in or pursuing a degree in Computer Science, Software Engineering, or a related field.

  • Something outstanding about your profile — top GPA, strong university, impressive projects, or an active GitHub.

  • Experience working in entrepreneurial, fast-paced, scrappy environments.

  • Willingness to work 7 days/week and participate in hacker-house setups in LatAm.

Nice to Have:

  • Portfolio or sample projects demonstrating full-stack development and open-source contributions.

Location

Based in San Francisco, CA. On-site role with hacker-house periods in Latin America. Visa sponsorship is available.
