Join Proton and build a better internet where privacy is the default

At Proton, we believe that privacy is a fundamental human right and the cornerstone of democracy. Since our inception in 2014, founded by a team of scientists from CERN, we have dedicated ourselves to providing free and open-source technology to millions worldwide, ensuring access to privacy, security and freedom online.

Our journey began with Proton Mail, the largest secure email service globally, and has since expanded to include Proton VPN, Proton Calendar, Proton Drive and Proton Pass. These tools empower individuals and organisations to take control of their personal data, break away from Big Tech’s invasive practices and defeat censorship. Our work impacts hundreds of millions of lives, from activists on the front lines defending freedom to leaders in governments protecting sensitive information. In some cases, Proton’s services have even been instrumental in saving lives by enabling secure and private communications in high-risk situations.

Proton is a profitable company that does not rely upon VC funding, supporting over 100 million user accounts with a growing team of over 500 people from over 50 different countries, coming from the world's top companies and universities. We value intelligence, learning potential and ambition in our hiring process. Adaptability is key as we navigate uncharted territories and redefine how business is conducted online.

Hiring at Proton is highly selective, with less than 1% of candidates hired. We believe smaller teams of exceptional talent will always prevail over larger teams with lower talent density. You'll have the opportunity to work with many of the world's top minds in their fields, ranging from former international math and science olympiad winners to chess champions.

We have a global mindset and big ambitions but remain a start-up at heart. We value empowerment and flexibility and keep our structure flat to keep moving fast and avoid unnecessary politics.

#LI-IM1

We are ShipMonk, and we provide logistics services in order fulfillment. Our main business is in the USA, but our modern platform is built by the Product Development team in Prague.

Here at ShipMonk, we process up to 100,000 orders per day in our peak season. Our book of business has more than 1,500 clients which are small and medium e-shops, mostly based in the US. We offer the ShipMonk platform as the solution for the whole process.  It covers everything from stocking the items to shipping the ready packages to all corners of the world!

We are looking for a skilled PHP Developer to join ShipMonk! This is an exciting opportunity to join our Product Development Team located in Prague. Please take a look at the details below.

Tech Stack:

• PHP 8.5
• Symfony 7
• Docker
• Kubernetes
• Doctrine ORM 3
• RabbitMQ
• MySQL 8
• GraphQL
• Elasticsearch

Our teams:

• Warehouse: optimization and automation of warehouse processes
• Internals: refactoring, tech-debt reduction, and legacy code removal
• Customer features: development of the functions of the existing web environment
• Frontend: TypeScript clients in React, E2E
• DataScience: AI, DWH, data-governance, prediction, and optimization, business intelligence
• QA: acceptance-criteria testing
• DevOps: Infrastructure, Kubernetes, CI/CD management and Cloud platform management
• Technical Product Managers: Asana & project management

What does it look like and what we are proud of:

• The main backend application provides a REST-like API for several types of clients (web, autonomous robots, iOS picker devices, microcomputer packers, automatic conveyors and more).
• We have the rest of the applications and clients in monorepo for easier CI checks, code sharing, etc.
• We have all services completely dockerized for local development. We deploy builds to a hosted Kubernetes cluster in AWS with a single click on the Argo CD several times a day.
• Each MR can be deployed on a separate cluster for one-button testing in the CI, so we don't argue about a test environment.
• We have set up a lot of checks in GitLab CI (PHPStan, PHP_CodeSniffer, PHPUnit, lint, editorconfig-check, migration check, security scans, renovate-bot).
• In addition to static analysis, we also do a two-round review and the operation is also verified by the QA team and E2E cypress tests.
• We have more than 15 000 database integration tests with the thoughtful creation of independent datasets for each test, ie no shared data that breaks forever.
• We directly automate the agreed coding-rules, so we have already written dozens of our own phpstan rules and coding-standard sniffs.
• We think about concurrence and design the application to withstand race conditions, which is not exceptional in a warehouse environment.
• The application is supported by DataDog, Sentry, and Opsgenie.
• Our database has grown to terabyte size, so even the optimization of SQL queries is becoming the daily bread of all of us.
• We deal with HA, failover, and autoscaling, almost no service runs for us only once.
• Having experienced colleagues is our huge advantage.
• We automatically generate documentation of all our REST-like endpoints.
• We open-source some of our best tools and contribute back to the OS community.
• We utilize code coverage.

If you like what we do, and our "story" got you interested, we look forward to seeing your resume, profile, story, or anything else you might have! There are no limits to creativity. Our Recruiter will get back to you as soon as possible. We look forward to hearing from you!
