Descripción

A better internet, where privacy is the default, is possible.

Building this better internet might seem daunting or even unthinkable, but at Proton, this is what we do every day.

Today, Proton makes privacy universally accessible.

Journalists from outlets like _The Guardian_ and _The New York Times_, some of the world's largest organizations, and people in more than 180 countries have signed up for over 70 million accounts.

Our diverse and dynamic team is made up of more than 400 members representing over 40 different nationalities.

While we are based in Geneva, Switzerland, we have offices in Zurich, Prague, London, Vilnius, Skopje, Taipei, and many more employees working remotely around the world.

Join one of Europe's fastest-growing companies to help us solve challenging problems and build new products that will reach hundreds of millions of people.

We want to create more than just one of the world's most impactful tech companies; we want to create a new internet that serves the interests of all people.

We need you, your voice, your ideas, and your ambition to make it happen.

Purpose of the role
You will be responsible for designing, building, maintaining and evolving features of the Proton Drive back-end.

Your goals are easy to understand, but hard to master:
(1) serve every Proton Drive client quickly, efficiently, and correctly; and (2) ensure the stability and correct functioning of the Proton Drive back-end. You are not an SRE, but you often think like one as you design and build the systems that must be rock-solid at the heart of Proton Drive.

Proton Drive offers a uniquely creative space for any Back-End Engineer:
the nature of our product makes migrations, mitigations and optimizations significantly more nuanced than in other, less-private systems: we can't inspect any of the data customers store on our systems, and that's by design

What you will do

Work closely with a group of Back-End Engineers and Architects to build resilient, massivelyscalable solutions for millions of people to rely on.
Document backend capabilities and their proper use so that all Proton Drive clients can implement correctlyfunctioning solutions.
Debug and repair vital systems such as the systems responsible for cleaning up file revisions and returning quota to users.

Job requirements

Experience with PHPbased entrypoints to a backend software stack.
Experience building scalable solutions.
Experience with profiling methods and tools.
Solid understanding of SQL (MySql preferred).
Solid understanding of security best practices.
Solid understanding of HTTP/REST, including both developing and consuming Webbased APIs
Highlevel understanding of cryptography concepts such as key exchange and the difference between symmetric and asymmetric encryption.

Bonus points for:

Operational experience such as SRE or oncall, demonstrating ability to diagnose and troubleshoot complex problems for critical systems.
Experience with Docker or similar containerization technologies
Experience with metrics graphing/analysis toolkits such as Grafana and OpenTelemetry
Experience with Golang
Experience with OpenAPI specs or other API documentation frameworks.
