About the Role

To ensure someone can be effectively supported throughout the intern we cn only look to hire an intern in either Singapore or in Europe.

You'll work remotely within our Middle-end / Tooling team, focusing on improving the observability of Dune, the OCaml build system. This isn't about cosmetic changes; it's about digging into Dune's core to expose how it builds things, making complex OCaml projects more understandable.

Responsibilities

• Dive into the Dune codebase, identify areas where the build rules are translated into actions.
• Implement modifications directly in Dune's source code to expose fine-grained information about builds.
• Develop and contribute pull requests to the upstream `ocaml/dune` project, working with the maintainers.
• Experiment with your changes and new tooling on real, large-scale industrial OCaml codebases to validate their usefulness.
• Collaborate asynchronously with the team.

Requirements

Must have:

• Solid OCaml programming skills. You need to be comfortable reading, understanding, and writing idiomatic OCaml.
• Experience with basic Git and GitHub workflows (branching, committing, pull requests, code reviews).
• Good written and verbal English communication skills for collaborating with a remote, async team and upstream maintainers.

Nice to have:

• Prior experience using more than one build system (e.g., Cargo, Make, Bazel, SCons, Nix, etc.).

What Success Looks Like

You've made significant contributions to Dune, resulting in working prototypes or even merged changes for a
tool that clarifies what happened during a build and why. This could involve exposing new internal Dune data
structures or developing a basic analysis tool on top, verified on an industrial codebase.

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

The ideal candidate is expected to:

• 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 Get

We 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

• Repurpose longer-form content (blog posts, videos) into concise, compelling social-first formats designed for maximum shareability and impact.
• Experiment with new content types, hooks, cadences, and storytelling approaches to continuously optimise engagement and reach.
• Collaborate with the broader marketing team, product, and content creators to ensure social messaging aligns with overall brand campaigns and objectives.
• Monitor social performance and engagement metrics to understand what resonates and adapt strategies accordingly.

Requirements

Must have:

• Proven experience managing social media for a brand, demonstrating a deep understanding of platform nuances and audience behaviours.
• Exceptional command of language with a portfolio showcasing your ability to write concise, engaging, and often humorous social copy.
• A natural instinct for current internet culture, trends, and the ability to leverage them authentically for brand communication.
• Strong editorial judgment and the ability to turn complex or technical topics into simple, compelling social content.
• Self-driven and autonomous: you can identify opportunities, execute ideas, and iterate without constant oversight.

Nice to have:

• Experience working in the SaaS industry or with B2B tech brands.
• Familiarity with Ahrefs' tools and the SEO/marketing landscape.
