Senior Backend Engineer working on shared backend framework and common services using PHP and Rust.

Обязанности

Design and build shared libraries, framework layers, and internal services used across every product
Turn recurring patterns into good abstractions
Write documentation and examples people actually use, and treat adoption as part of shipping
Improve the day-to-day: build times, local dev setup, test ergonomics, debuggability, developer experience
Work in the open with product teams — RFCs, design reviews, and the occasional pull request into someone else's repo to show what you mean
Work closely with other developers to help integrate libraries seamlessly into applications

Требования

5+ years building and operating backend systems in production, including code you stayed responsible for long after launch, with a focus on modern PHP
Working knowledge of Rust, or clear evidence you can get there quickly — we care that you understand ownership and lifetimes
Genuine taste in API design. You have opinions about naming, defaults, error handling, and what belongs in a library versus a service
A feel for architecture at codebase scale — you have worked somewhere large enough that module boundaries and dependency direction mattered, and you have views on what keeps a monorepo healthy
Experience evolving shared code that other teams depend on, and doing it without breaking them
A security mindset. You think about how the abstraction you just wrote will be misused
The influence to get an internal library adopted rather than worked around, and the patience to carry a design through disagreement between two teams who both think they're right

Будет плюсом

Domain-Driven Design, or similar experience modelling complex domains where the boundaries matter
Background in developer tooling, platform, or DX teams
Contributions to open source, especially libraries with real users
Experience migrating a codebase incrementally between architectures or languages
Experience with applied cryptography, key management, or end-to-end encrypted systems
Experience with building CI/CD
Even if you don’t meet all the requirements listed above, but feel you could still be a great fit, please still apply.

was founded in 2014 by scientists from CERN on a simple truth: privacy is a fundamental human right . Since then, we’ve built the world’s largest encrypted email service ( Mail) and expanded into VPN, Drive, Pass, and Calendar—tools used by millions globally to protect their freedom, fight censorship, and keep their data safe. In some situations, has literally helped save lives!

The Foundation team builds what the product teams build on: the shared backend framework, the internal libraries, the common services and abstractions that every application reaches for. If several teams need it, it should exist once, and be good.
You will work in PHP for API related work, and in Rust for components where performance and memory safety justify it or for microservices. You will own libraries or initiatives end to end: design, implementation, documentation, versioning, and the migration path for everyone already depending on the old version.
Architecture is a large part of this role. Many engineers work in the same monorepo, which means module boundaries, dependency direction, and ownership are not academic concerns — they decide whether the codebase stays navigable or slowly turns into something nobody can change safely. You will help define those boundaries, make the structural calls that keep teams from stepping on each other, and do some work to enforce them: writing the RFC, adding rules, untangling the cycle that shouldn't have been there. None of this happens in isolation. You will work closely with other teams who consume and use what you build.
