Work type: onsite

Location: Palo Alto, California, United States; Singapore

Type: Full-time

Summary

This role is ideal for a mid-level backend engineer who thrives on low-level systems programming and has a genuine passion for OCaml. You should be comfortable operating in a high-scale environment where you aren't just writing code, but also managing the hardware and OS-level implications of handling 25 petabytes of live data. The standout feature of this position is the high level of autonomy and vertical responsibility. You will own the entire development cycle of your components, from design to production support. While the salary isn't listed, the company promises a "competitive compensation package" and a modern, high-end office environment in Palo Alto or Singapore for those preferring an on-site culture. **You might be a good fit if you:** * Have mastered OCaml and understand how to write efficient, maintainable code. * Are comfortable "under the hood" with Linux internals, networking, and distributed systems. * Prefer a practical, fast-paced development cycle over academic perfectionism. * Want to take full ownership of your work rather than being a small cog in a giant machine.

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.

### 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](https://ahrefs.com/jobs/reasonml-developer) 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](https://www.youtube.com/watch?v=0m1rZ2KTLIQ)

[Remote] Hardware allowance
