What is the difference between Internship Ocaml Programming vs Software Developer?

AspectInternship Ocaml ProgrammingSoftware Developer
Required CredentialsBasic programming knowledge, possibly some coursework in OCamlBachelor's degree in Computer Science or related field, experience varies
Work EnvironmentInternship setting, learning-focused, often in tech companies or research labsFull-time employment, collaborative teams, diverse industries
Industry UsageSpecialized in functional programming, research, or niche software projectsBroad industry application, including web, mobile, enterprise software
Search & Comparison IntentEntry-level, learning OCaml, internship opportunitiesCareer development, full-time roles, software development skills

In summary, Internship Ocaml Programming is an entry-level position focused on learning OCaml within a temporary internship setting, while a Software Developer is a full-time role requiring broader programming skills and experience. Both roles are essential in tech, but they differ in scope, responsibilities, and career stage.

What is an Internship in OCaml Programming?

An Internship in OCaml Programming is a temporary position, typically for students or recent graduates, where you gain hands-on experience working with the OCaml programming language. Interns often assist on software development projects, learn functional programming principles, and contribute to real-world applications under the guidance of experienced mentors. These internships help build practical coding skills, expand your professional network, and may lead to future job opportunities in functional or systems programming.

What types of projects or tasks can an intern expect to work on during an OCaml programming internship?

During an OCaml programming internship, interns typically contribute to real-world projects such as developing or maintaining software libraries, implementing algorithms, or assisting with code reviews. You may also work on debugging and optimizing existing OCaml applications, writing unit tests, or contributing to open-source projects. Interns often collaborate closely with experienced developers, participating in team meetings and code discussions, which provides valuable learning and mentorship opportunities.

Job description

About the Position

We are excited to announce research internships in our Tools and Compilers group. We're looking for PhD and masters students with outstanding research experience in programming languages, compilers, verification, and related areas.

Jane Street's Compilers team focuses on improving OCaml as a foundation for Jane Street's ever-growing technology stack, in collaboration with the greater OCaml community. We work on many different aspects of the compiler, aiming to make it easier for developers to express their ideas in OCaml, to improve the performance of the generated code, and to make the OCaml compiler itself faster and easier to use.

Over the years, we extended the type system with support for novel language features, re-engineered the optimizer ground-up, and added feedback-directed optimization. We also extend and enhance the surrounding toolchain, working on tools for profiling, debugging, documenting, and building automation. The vast majority of our work is open-source, and we upstream as much as we can to the mainstream OCaml compiler.

During the application process, we will work with you to identify a project that aligns with your research expertise and interests. Examples of areas we are interested in exploring include:

  • Type systems that track locality and uniqueness
  • Superoptimization
  • Compiler testing and validation

During the internship, you will work in collaboration with your mentors on one project for about 10-12 weeks. You'll learn how we use OCaml in our day-to-day work, and gain exposure to the libraries and tools that are foundational to our internal systems. You'll gain a better understanding of the wide range of problems we solve every day. You'll try out new ideas and apply state-of-the-art research to a large actively-developed production codebase.

You'll also be able to access our physical and virtual educational resources, attend guest speakers and social events, and hopefully get a real sense of what it would be like to work here full-time.

About You

We're looking for PhD and masters students with outstanding research experience in programming languages, compilers, verification, and related areas. We don't expect you to have a background in finance, OCaml, or functional programming. Please include the list of your peer-reviewed publications in your resume.
