What is an OCaml?

An OCaml job typically involves software development using the OCaml programming language, which is known for its functional and statically typed features. Professionals in this role often work on building reliable and high-performance applications, including compilers, financial systems, and formal verification tools. OCaml developers may be responsible for writing and maintaining code, optimizing performance, and integrating with other technologies. These roles are commonly found in industries such as finance, academia, and systems programming.

What types of projects do OCaml developers typically work on, and what does a day-to-day workflow look like?

OCaml Developers are often involved in projects that require high reliability and mathematical precision, such as financial software, compilers, static analysis tools, or research applications. On a typical day, you might write and test functional code, participate in code reviews, collaborate with teammates during agile sprints, and troubleshoot existing software modules. Interaction with cross-functional teams is common, as you may need to align closely with product managers or QA engineers to deliver robust solutions. The work environment is often collaborative and intellectually stimulating, providing opportunities to continually enhance programming and problem-solving skills.

What are the key skills and qualifications needed to thrive in the OCaml position, and why are they important?

To thrive as an OCaml Developer, you need strong proficiency in functional programming concepts, in-depth knowledge of the OCaml language, and a background in software engineering or computer science. Familiarity with version control systems like Git, CI/CD pipelines, and OCaml-specific build tools such as Dune is typically required. Excellent problem-solving abilities, attention to detail, and the capacity to communicate complex ideas clearly are valuable soft skills. These competencies are crucial for producing reliable, high-performance code and collaborating effectively within engineering teams using OCaml.

What can I do with OCaml?

OCaml is a functional programming language used in roles such as software development, data analysis, and formal verification. Job opportunities often involve developing high-performance applications, working with compilers, or creating tools that require strong type safety and concurrency support. Proficiency in OCaml can also be valuable in research, finance, and systems programming environments.

Job description

About the Position

Our goal is to give you a real sense of what it's like to work at Jane Street full time while also providing a truly unparalleled educational experience. As an intern, you are paired with full-time employees who act as mentors, collaborating with you on real-world projects we actually need done.

In this internship, you'll learn how we use tools to make programming faster, more pleasant, and more reliable. We apply these same principles to our hardware engineering work, and we're looking for people who are interested in using programming language technology to improve the process of designing, testing, and validating hardware designs. We use Hardcaml, an OCaml library for succinctly describing hardware in RTL. Hardcaml is tightly integrated into our development environment, so you'll also gain lots of exposure to the libraries and tools that are foundational to our internal systems. No previous knowledge of Hardcaml is required.

The hardware team at Jane Street works on both FPGA and ASIC designs. Depending on your background and experience, we'll craft a project that gives you exposure to our shared Hardcaml tech stack, as well as targeting an FPGA or ASIC platform.

During the program, you'll dive deep on one project, mentored closely by the full-time employees who helped design it. Some intern projects consider big-picture questions that we're still trying to figure out, while others involve building something new. Your mentors will help you gain a better understanding of the wide range of problems we solve every day. We expect interns to build hardware applications from concept to a working design; your projects will predominantly involve OCaml & Hardcaml, for both RTL design and testing/integration.

If you'd like to learn more, you can read about our interview process, meet some of our newest hires, or check out our OCaml All The Way Down talk and Programmable Hardware podcast episode. You can also learn more about Jane Street's internship program here.

About You

We don't expect you to have a background in finance, OCaml, functional programming, or any other specific field- we're looking for smart people who enjoy solving interesting problems. We're more interested in how you think and learn than what you currently know. You should be:

  • Comfortable with a software programming language
  • Experienced with a Hardware Description (or Construction) language (VHDL, Verilog, Chisel, Pymtl, or other), for both writing and testing hardware designs
  • Experienced working with FPGA or ASIC vendor tools - Vivado or Quartus for FPGAs, Genus or Innovus for ASICs
  • Experienced with building a working hardware project (either FPGA or ASIC) through an academic, professional, or personal project
  • Interested in learning how to use FPGAs or ASICs in the context of networking
