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 organizations 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, 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 will 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. Tired of blending into the crowd? Join us and do work you can truly be proud of. Check our open-source projects here!

The team:

 ⭐Our Mobile Engineering team

There are ~40 Android engineers at Monzo and we’re looking for more to join the team. We have several non-graduates; only some of us studied Computer Science; some of us have worked in huge companies; some have only ever worked in startups; others are former consultants. As long as you enjoy learning new things, we’d love to talk to you.

 Monzo works in small, interdisciplinary teams

We have around 400 engineers out of roughly 4,500 people in total - and we have big ambitions. There are many interesting challenges ahead, and we're happy for people to move between teams or to specialise, whatever you prefer. As an engineer here you'd be able to work directly with anyone across the company, and we run regular knowledge-sharing sessions so you’ll learn heaps about everything from how banks work to effective communication.

🔑You’ll play a key role by...

We’re searching for product-focused Android engineers to evolve our native mobile app. You’ll take pride in building polished user experiences, and you’ll balance the need for well-tested resilient code with moving fast and iterating. 

You’ll be working on a product that is a part of day to day life for more than 11 million people already, and your work here will shape the way that people interact with their finances.

As an Android Engineer at Monzo you'll work in a small, autonomous product squad alongside iOS Engineers, Backend Engineers, User Researchers, Product Designers, Product Managers, QA Testers, and Data Scientists.

You and your team will be responsible for an overall company goal, rather than building a specific feature - you'll have the opportunity to have impact on both what we build, and how we build it. Mobile engineers at Monzo work on everything from the personal banking product to customer support tools. We also have a small mobile platform squad dedicated to enabling other engineers to move faster.

Every week we meet as an Android discipline to discuss tools, techniques, problems we're encountering across the company and work together to improve our codebase and processes.

You'll report to an engineering manager who will meet with you every 1-2 weeks 1:1. They’re dedicated to helping you grow and develop as an engineer.

Our Android app

Our app is 100% Kotlin, built using MVVM (Model View ViewModel) and Coordinators, and modularised by product feature.

We use RxJava, Retrofit and Moshi for API calls and Dagger for dependency injection. We’re starting to use Coroutines for most new features. Room is our choice for persistence, and we use repositories for interacting with data. We’ve built out our design system with Compose. 

We use GitHub Pull Requests to do code reviews, and write unit tests for our ViewModels, Coordinators, and any other classes which contain logic. We write tests for all of our Compose screens and snapshot test them with Happo. We also use Espresso to test flows, which are executed via our continuous integration system.

We’ve previously written about building Monzo Chat on Android, which goes into detail on some of these elements.

🤩 We’d love to hear from you if…

• You care about the impact your work has on our customers, and optimise for outcomes rather than the number of lines of code you output
• You’re excited about and have experience in programming in Kotlin
• You’ve shipped and iterated on at least one app in the Play Store
• You have a product mindset: you care about customer outcomes and you want to make data-informed decisions
• You love turning excellent design into beautiful products
• You’re comfortable working in a team that deals with ambiguity
• You have an understanding computer science principles

We're on the look out for L30 Engineers at the moment, you can read more in our Engineering Progression Framework you will be interviewed across the whole framework, so if you're not sure what level you're aiming for chat to your recruiter! 

🙌What’s in it for you:

💰Base salary range for this role is depending on experience + equity + stock options & benefits 

💰 Base salary for this role is depending on experience + Incentive Awards tied to your performance  + benefits 

⏰ We offer flexible working hours and trust you to work enough hours to do your job well, at times that suit you and your team.

📚Learning budget of €1,200 a year for books, training courses and conferences

🌈 The application journey has 3 key steps

Our interview process involves three main stages: 

1. Initial Call 
2. Take home task or pair coding exercise 
3. Final interview including a system design and a behavioural interview 

This process should take around 2-3 weeks - your schedule is really important to us, so we promise to be as flexible as possible! 

We have some guidelines on using Artificial Intelligence (AI) to ace an application and interview at Monzo. You can read them here.

There’s a detailed blog on the interview process, for extra details, hints and tips.

We’ll only close this role once we have enough applications for the next stage. Please submit your application as soon as possible to make sure you don’t miss out. 

If you're successful in applying for this role, we'll work with you to find a start date. In some cases, there might be a delay in when you can be released from your current role so that we can make sure things continue to run smoothly. We’ll be sure to communicate this with you and keep you updated.

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

Proton 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 (Proton Mail) and expanded into Proton VPN, Proton Drive, Proton Pass, and Proton Calendar—tools used by millions globally to protect their freedom, fight censorship, and keep their data safe. In some situations, Proton has literally helped save lives!

We are profitable, independent (no VC control), and selectively hire from the top ~1% of applicants. Our 500+ team members across 50+ countries come from leading organizations and elite academic backgrounds. We move fast, keep hierarchy light, and prioritize impact over optics. If you want to do meaningful work with exceptionally high-caliber people, this is it. Join us and do work you can truly be proud of. Check our open-source projects here!

The Payments Team

The goal of the Payments team is to enable revenue generation for the entire Proton ecosystem. This comes in the form of introducing new payment methods for users to architecting our client libraries. This team has impact across all of Proton's products and is critical to the success of the business as a whole.

• As Proton is a global Company, the Payments Team works to continuously expand the possibilities for users to pay with various payment methods, beyond just plain credit cards or Paypal.

• Differently than many other stacks at Proton, the Payments stack depends largely on external services such as payment providers, tax-information providers, currency-conversion providers... As such it is critical, for the success of the service, to build with resilience.
• Internally our backend code is in general based on PHP/Symfony, our frontend is based on React, our mobile code is based on Kotlin (on Android) and on Swift (on iOS), with a growing shared codebase in Rust.
• All our client-code is open-source and GPL3.
• We are migrating our infrastructure to Kubernetes.
• Everything runs on premise in Proton's data-centers.
• To organize our work we use classic tools such as Jira and Confluence.

Future Plans:

• With payments being the backbone of any subscription business, we have ambitious plans to expand the team to cover a wide breadth of topics ranging from demystifying payment performance data across regions/products, to thinking about the holistic strategy of product catalogs, and everything in between. This particular team requires someone who is a strong generalist, who thrives with ambiguity. There's huge potential for growth no matter the domain, and the outcome for any candidate is an in-depth view into how money moves globally.

What you will do:

• Build features in all of Proton's products.
• Close interactions with products and engineers across the company.
• Build scalable software architecture through software engineering best practices.
• Optimise user experience and design.

Job requirements:

• Proven experience with back-end development 
• Expertise in building scalable, high-performance solutions

• Knowledge of security best practices and experience implementing secure software solutions
• In-depth understanding of HTTP/REST, including both the development and consumption of web-based APIs
• Solid grasp of cryptographic concepts, including key exchange, and the distinction between symmetric and asymmetric encryption

Bonus points for: 

• Experience within the payments domain

Even if you don’t meet all the requirements listed above, but feel you could still be a great fit, please still apply.

The role:

You will be responsible for designing, building, maintaining and evolving Proton applications on Windows. This includes not only building the application internals (managing and syncing local and remote state, performing cryptographic operations, etc) but also helping us to build a resilient, scalable application (graceful degradation; log and metrics streams free of personally identifiable information). You will be involved in the entire application lifecycle, including Gitlab configuration, deployments, monitoring and alerting, and operational incident response. While this position is not a "full-stack" position, you will be expected to collaborate with backend engineers to drive any necessary changes and/or new features needed for the Windows experience.

What you will do:

• Be part of a small team working to bring a "privacy by default" solution to our clients on Windows.
• Develop an application that delights a wide range of users, from layperson to technical, and gives confidence that their online privacy is in good hands - while getting the complexity of end-to-end encryption out of the way.
• Invest in testing and automation to improve the team's productivity and software delivery cadence.
• Think critically on how to divide problems into iterations of simpler, composable solutions. Re-evaluate the minimum scope as necessary to meet objectives on-time.
• Insist on high standards for application monitoring and alerting, in order to ensure a smooth customer experience at all times.

We we are looking for:

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

Proton 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 (Proton Mail) and expanded into Proton VPN, Proton Drive, Proton Pass, and Proton Calendar—tools used by millions globally to protect their freedom, fight censorship, and keep their data safe. In some situations, Proton has literally helped save lives!

We are profitable, independent (no VC control), and selectively hire from the top ~1% of applicants. Our 500+ team members across 50+ countries come from leading organizations and elite academic backgrounds. We move fast, keep hierarchy light, and prioritize impact over optics. If you want to do meaningful work with exceptionally high-caliber people, this is it. Join us and do work you can truly be proud of. Check our open-source projects here!

The Payments Team

The goal of the Payments team is to enable revenue generation for the entire Proton ecosystem. This comes in the form of introducing new payment methods for users to architecting our client libraries. This team has impact across all of Proton's products and is critical to the success of the business as a whole.

• As Proton is a global Company, the Payments Team works to continuously expand the possibilities for users to pay with various payment methods, beyond just plain credit cards or Paypal.
• The team works in tight collaboration with the Account Team (responsible for the Proton user lifecycle), the Proton Finance team, and every single Business Unit to ensure that plans, promotions and pricing meet user expectations.
• The mission of the team is to empower anyone in the world who wish to use Proton services, to become a Proton subscriber by building enticing interfaces, being able to progressively reach global markets, by providing the methods and tooling allowing users to pay, and for the Proton organization to properly being able to measure growth, and to follow the relative financial regulations

Tech Stack and Tools:

• Differently than many other stacks at Proton, the Payments stack depends largely on external services such as payment providers, tax-information providers, currency-conversion providers... As such it is critical, for the success of the service, to build with resilience.
• Internally our backend code is in general based on PHP/Symfony, our frontend is based on React, our mobile code is based on Kotlin (on Android) and on Swift (on iOS), with a growing shared codebase in Rust.
• All our client-code is open-source and GPL3.
• We are migrating our infrastructure to Kubernetes.
• Everything runs on premise in Proton's data-centers.
• To organize our work we use classic tools such as Jira and Confluence.

Future Plans:

• With payments being the backbone of any subscription business, we have ambitious plans to expand the team to cover a wide breadth of topics ranging from demystifying payment performance data across regions/products, to thinking about the holistic strategy of product catalogs, and everything in between. This particular team requires someone who is a strong generalist, who thrives with ambiguity. There's huge potential for growth no matter the domain, and the outcome for any candidate is an in-depth view into how money moves globally.

What you will do:

• Build features in all of Proton's products.
• Close interactions with products and engineers across the company.
• Build scalable software architecture through software engineering best practices.
• Optimise user experience and design.

Job requirements:

• Proven experience with back-end development 
• Expertise in building scalable, high-performance solutions
• Proficiency with profiling techniques and performance optimization tools
• Experience leading a team initiative from discovery to production
• Strong understanding of SQL (MySQL preferred) and data modeling best practices
• Familiarity with Redis or other caching technologies for performance optimization
• Knowledge of security best practices and experience implementing secure software solutions
• In-depth understanding of HTTP/REST, including both the development and consumption of web-based APIs
• Solid grasp of cryptographic concepts, including key exchange, and the distinction between symmetric and asymmetric encryption

Bonus points for: 

• Experience within the payments domain

Even if you don’t meet all the requirements listed above, but feel you could still be a great fit, please still apply.
