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
Ahrefs is looking for a backend developer with deep understanding of networks, distributed systems, OS fundamentals and taste for simple and efficient architectural designs. Our backend is mostly implemented in OCaml with some C++.
In this role, be prepared to deal with 25 petabytes of live data, OCaml and Linux on a daily basis.
Ahrefs OCaml
Basic Requirements:- Proficiency in OCaml
- Knowledge of C++ is a plus but not essential
- Independently deal with bugs, schedule tasks and investigate code
- Make well-reasoned technical choices and take responsibility for them
- Understand the whole technology stack at all levels: from network and user-space code to OS internals and hardware
- Handle full development cycle of a single component i.e. formalize task, write code and tests, setup and support production, resolve user requests
- Approach problems with a practical mindset and suppress perfectionism when time is a priority
- Write flexible, maintainable code and adapt to post-launch requirements/tweaks
These requirements stem naturally from our approach to development with fast feedback cycle, highly-focused personal areas of responsibility and strong tendency to vertical component splitting.
If your preference is leaning towards making the web functional and working on user-facing stuff, you may want to consider our ReasonML position instead.
What You GetWe offer:
- Competitive compensation package
- Informal and thriving work atmosphere
- Above-average perks and fringe benefits
- [Office] First-class workplace (hardware, software, etc) in the modern office
- [Remote] Hardware allowance
