What is an OCaml job?
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 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 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.

Job description
About the Position
We are looking for a Software Engineer with experience in high-performance, low latency systems. You'll work closely with our quantitative researchers and developers, taking a holistic approach to design and optimize our fast-trading systems.
We build systems primarily in OCaml with only small amounts of C and C++, but you don't need any experience with OCaml in particular (we can teach it to you) or knowledge of the financial markets. The most important qualification is experience with low level systems programming and optimization, whether it is in C, C++, or any other language.
About You- Experience with low level systems programming and optimization, and working on network applications that require extremely low latency and high throughput
- Can understand, interpret, and improve application performance through hardware performance counters and other profiling tools
- Has a thorough understanding of modern computer architecture and can talk to others about it; for example, can you describe modern x86 AMD and Intel cache hierarchies?
- Some experience with fast-packet processing in user space and common kernel-bypass implementations would be ideal (such as Solarflare OpenOnload/TCPDirect/ef_vi, Exablaze, InfiniBand verbs, DPDK)
- Experience working around the performance challenges of languages with a managed runtime (such as Java or C#) and familiarity with a typed functional language are a plus
