Role
Who you are
- Deep experience with backend development (Python, PHP, or Go)
- Experience with frontend design and development (JavaScript, React, Typescript, or jQuery)
- Experience building complex production systems
- Experience with data processing and storage (MySQL, MongoDB, Redis, Kafka, Elastic, Ceph, ClickHouse)
- Able to work autonomously and lead the whole development process, from design to QA
- Excellent English communications, both written and spoken
Desirable

What the job involves
- MSA is a highly multi-disciplinary group started in 2019 to tackle difficult mail delivery, spam, abuse, and account security problems that impact the Proton ecosystem
- We built sophisticated systems from scratch that combine human intelligence and machine learning to make tens of millions of realtime or asynchronous decisions each day
- As of late 2023, our areas of focus are 1) mail delivery and spam, 2) abuse and account security, 3) site reliability of Proton
- Over the past few years, our custom systems have reduced spam filter misclassifications by over 60%, blocked millions of abusive bulk signups, protected hundreds of thousands of users from account compromise by attackers, and mitigated hundreds of DDoS attacks
- In order to move fast with limited resources, we are organized into autonomous teams responsible for the whole system, with expertise across infrastructure, data storage, backend, web and mobile apps, machine learning, security and operational excellence
- In 3 years, we grew from 2 engineers to over 30 engineers and analysts, spread across 3 continents for 24/7 coverage
- We are looking for humble, mission-driven, systems-thinking people who want to make a big impact in a startup environment
- MSA builds and operates many services responsible for different domains. You will:
- Work with other engineers and analysts to design, build, and operate these systems
- Work on special user-facing features involving frontend and backend software development
- You will have the opportunity to play Product or Project Managers roles and lead the whole planning and development process
- Be responsible for the operational excellence of the systems/features and their interaction with other systems
- You may work on MSA's custom systems written in Python or on the main Proton API written in PHP or on Proton Web apps written in React or even on native iOS and Android mobile apps
Our take
Proton is a Geneva-based startup founded by former CERN worker and internet privacy advocate Andy Yen. It provides internet users with encrypted webmail, calendar, drive, and VPN services.
Proton maintains its pro-privacy ethos using a Swiss VPN, protected by strict Swiss privacy laws. In essence, it has established a connection between the personal and the political, smartly utilising the country’s national laws to benefit people and organisations globally. Proton also funds charities and movements such as the World Wide Web Foundation and Netblocks, further cementing it as an influential NGO.
Perhaps Proton’s most important quality is its determination to maintain independence from advertisers and companies. Originally founded on donations, Proton has funded itself via grants rather than venture capital so that all of its customer's data is never at risk of being mined. One effect of this is that to keep up with the increasing competition in the data privacy sector, Proton has expanded its services to allow more cross-selling and simultaneously has more products to offer, such as drive and calendar privacy.
