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 today supports 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. We believe smaller teams of exceptional talent will always prevail over larger teams with lower talent density. Proton has become profitable and reached scale without relying upon VC funding, largely due to superior talent that allows us to do things faster, more creatively, and more efficiently.

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 social media pages to learn more about us: Twitter, Reddit, Instagram.

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:

• Strong experience in .NET development
• Strong experience building and maintaining Desktop Windows applications
• Strong experience with concurrent multi-threaded programming
• Working knowledge of file systems
• Working knowledge of Git
• Bachelor's or master’s degree in a relevant field of study
• Experience with owning and maintaining large software components
• Experience with gradual rollouts and metrics/monitoring/alerting frameworks

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

What We Offer

• Office First: Collaboration is easier and more effective in person, which is why we have offices in Geneva, Zurich, Prague, Barcelona, Paris, London, Vilnius, Skopje, and Taipei. You can also enjoy working from home up to 30% of the time, while enjoying great company during our three core days in the office. 
• Technology: We provide all the devices and software you need to excel in your role, ensuring you have the best tools at your disposal to achieve your goals.
• Food: Lunch and snacks are provided by Proton every day at our offices.
• Transport: We will always support our employees with transport costs through subsidizing public transport, bike allowances, or parking spaces based on your office location.
• Stock Options: At Proton, we are all owners of the company and you get stock options when you join us.
• Flexible Working: You can define your own working hours as long as it works with team meetings.
• Learning and Development: We are committed to your professional growth. Proton offers various learning opportunities, including training programs, conferences and events, and continual learning.
• Employee Benefits: Comprehensive health insurance plans, competitive retirement savings options, generous vacation and leave policies, and wellness programs.
• Work that Matters: Proton is a community-first organization, started with the support of a crowdfunding campaign and built with community input. To this day, Proton’s only source of revenue is user subscriptions. Over 100 million people trust and support Proton, and we put our users and community first in everything we do.

You'll work primarily in Kotlin, with opportunities in Elixir and Golang. We practice Extreme Programming: small iterations, daily deliveries, and a focus on technical design quality and deep problem understanding.

Our tech stack includes Kotlin, Golang, Elixir, Java, AWS, Kafka, PostgreSQL, and Kubernetes, supported by observability tools like Prometheus, Grafana, and Honeycomb. We also use AI-assisted development tools including Cursor and GitHub Copilot.

What You'll Do

• Build critical infrastructure from scratch: Contribute to the design and implementation of a newly architected global accounts platform. You'll help migrate existing systems to a modern, event-driven, decoupled architecture that enables scalability and resilience across regions.
• Master event-driven architecture: You'll be working extensively with Kafka to build a truly decoupled, resilient system. Event-driven architecture is essential to our goal of ensuring that failures in one part of the system don't bring down banking operations globally. This isn't just a technical requirement—it's the foundation of building a platform that can handle the complexities of multi-region banking.
• Solve complex compliance challenges: Design flexible systems that handle varying regulatory and verification requirements across different regions and use cases. You'll make compliance requirements maintainable and natural rather than an afterthought.
• Enable other teams: Build a self-service platform that empowers internal teams across the organization to contribute to and build on top of.
• Work globally: Your work will directly impact EU and LATAM markets, with potential US expansion on the horizon.

You'll Be Great for This Role If

• Strong technical foundation: Solid backend development experience in Kotlin, with interest in working across multiple languages (Golang, Elixir). You understand system architecture, object-oriented and functional design principles, data modeling, and API design (RESTful and event-driven).
• Event-driven architecture expertise: Proven experience with Kafka and event-driven systems. You understand how this enables true decoupling and resilience in distributed systems.
• Distributed systems mastery: You've built tested, observable, scalable, robust, and fault-tolerant distributed systems. You have hands-on experience with AWS, Docker, Kubernetes, cloud-native architectures, and relational databases, understanding data consistency and performance considerations.
• Ownership and craft: You take full ownership of the software you ship, from design to production readiness. You value clean, maintainable code and continuously refactor to keep designs simple and scalable.
• Motivated by the challenge: You're curious and energized by complex problem-solving rather than just shipping features quickly. You thrive in environments with fast iterations and careful design, where understanding the problem deeply is valued over rushing to delivery. You're excited by the opportunity to architect critical systems from scratch and work in a team that practices Extreme Programming with daily deliveries.
• Collaborative mindset: You communicate respectfully, share knowledge openly, and actively support your teammates' growth.

Why you’ll enjoy working at SumUp

• Be part of a company that values diversity and celebrates unique perspectives.
• Work with a global team of skilled professionals in an environment that fosters collaboration, learning, and growth.

The Scale of the Challenge

At Flo we don't just have users, we have a global community. We are the #1 women's health app, in the last month alone, we saw 8.6M new installs and a 2.8M increase in active users.

When millions of people trust you with their most personal health data, security isn't a feature — it's a foundation. We are looking for a Cloud Security Engineer to join Velocity, our Internal Platform team. Your mission is to ensure that every system, pipeline, and tool our engineers rely on is secure by default — so they can ship fast without ever compromising trust.

The Mission: Velocity

The Velocity team exists to eliminate friction. We build and own the foundation everything else runs on: cloud infrastructure, developer tooling, and SRE practices. You will:

• Embed Security Into the Platform: Bake security, compliance, and best practices into the core stack so they're invisible to developers and impossible to skip.
• Automate Everything: Drive security-as-code across infrastructure, CI/CD pipelines, and container lifecycles — making manual gates a thing of the past.

What You Will Do

• Cloud Security Posture: Own and continuously strengthen Flo's AWS security posture using tools like GuardDuty, Inspector, Security Hub, and SSM Patch Manager.
• Container & Supply Chain Security: Harden container image security end-to-end — patch vulnerabilities automatically with Copacetic, sign and verify images with Cosign/Sigstore, and enforce policies at admission with Kyverno.
• Policy as Code: Manage CI/CD security across the organisation using policy-as-code tooling (Kyverno, Checkov), ensuring standards are enforced programmatically.
• Security Observability: Build visibility into security performance by measuring and visualising actionable metrics using tools like Databricks Dashboards or Looker.
• High-Scale Privacy: Support the infrastructure for industry-leading privacy features, such as our TIME-recognised "Anonymous Mode."
• Culture & Thought Leadership: Shape Flo's broader security culture through proactive engagement, documentation, and cross-team collaboration.

What You Bring

• Experience: 7+ years in Infrastructure Security, Cloud Security, or Security Engineering roles.
• Cloud Native Mastery: Deep expertise in AWS security services and best practices is essential.
• Infrastructure as Code: Proficient in Terraform and Terragrunt — you run everything as code.
• Container Security: Strong knowledge of Kubernetes security, image hardening, and admission control.
• Identity & Access: Solid understanding of identity management principles — SSO, OAuth, JWT, SAML.
• Automation Mindset: Comfortable scripting in Python, Bash, or similar to automate security workflows.
• Network Security: Understanding of modern network security principles and their practical application.
• SSDLC: Experience building Secure Software Development Lifecycle phases into engineering workflows.

Bonus Points

• Experience with security monitoring and event correlation systems (IDS/IPS, SIEM, AWS-native tooling).
• Knowledge of Zero Trust Architecture and its implementations (e.g., Cloudflare).
• Familiarity with secret management processes and tools.
• Experience in multi-cloud environments (AWS and preferably GCP).
• Understanding of business continuity principles (BIA, DRP).
• Professional accreditations such as AWS Security Specialty, CKS, or CISSP.

Why Join Flo?

• High Impact: Your work directly protects the health data of millions - Flo is rewriting women's health, and you'll make sure it's done securely.
• Autonomy: We hire experts and empower you to deliver.
• Cutting-Edge Stack: Work with modern security tooling (GuardDuty, Kyverno, Cosign, Elastic Cloud Security) deployed on real production infrastructure at massive scale.

What you'll be doing

You'll be responsible for:

• Lead and scale a team of 5+ engineers and organise work towards the product vision
• Work closely with the development team and Product Manager to deliver business value in a timely manner while following and improving upon established quality metrics.

• Implement the most suitable development processes (principles, rules) for the team
• Coach the team to learn and apply engineering best practices in various areas starting from UI standards and CI/CD to API design and Secure SDLC
• Continue to form and grow your team – hire and onboard new members, perform training activities, help team members to follow their path for professional growth 
• Solve or escalate issues within and outside the team
• Ensure healthy collaboration with other teams, identify and manage technical and organisational dependencies
• Support an environment of transparency by providing prompt feedback, both gently and honestly

Your Experience

Must have:

• 6+ years of experience in one of the following programming languages: Scala, Java, Kotlin, Objective C/Swift.
• Experience in designing and implementing robust distributed systems
• 4+ years of team management: establishing processes in a cross-functional team, building tech roadmaps, experience in change management
• People management skills – providing one-on-ones, resolving conflicts, creating career development plans, mentoring and growing engineers
