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.

We are seeking an innovative and forward-thinking Engineering Manager passionate about building a world-class platform through a world-class team. Driving the technical direction of the technology, the evolution of the team, and the engineering excellence to make great things happen.

About the Netting Team

The team builds and maintains our multilateral netting platform — a critical solution that enables enterprise customers to consolidate thousands of intercompany payment obligations into a streamlined set of net settlements. Instead of every entity paying every other entity individually across borders, currencies, and banking relationships, our platform calculates optimal net positions and dramatically reduces the volume of cross-border payments that actually need to move. The result: reduced transaction and banking fees, and far less operational overhead.

It's a domain where precision matters — if you enjoy building systems where correctness, performance, and usability intersect with real financial impact, this is a team where your work is felt directly on the bottom line.

What You’ll Do:

• Lead a portfolio of diverse technology projects and a team of software engineers with deep experience in cloud native services, and full stack systems to create solutions that help meet the needs of business and customers
• Drive decisions on the design, architecture, and delivery of systems
• Build teams and be an active coach and mentor to your team and grow them in their careers
• Drive agile development and analytical methodologies every day
• Strive to continuously improve the operations, processes, methodologies, technology choices, and practices of the team
• Interact with your team, customers, and peers to share information and improve cross-department processes
• Strive for transparency and partnership between our engineers and our business partners
• Engage in concept discussions, and proposed technology solutions, to meet business objectives and influence such decisions
• Ensure all work meets quality, operational, and architectural standards needed for organizational success
• Be a champion of the YBIYRI ethos (you-build-it-you-run-it), which includes participating in their on-call pager rotation.

Who You Are:

• A leader, first and foremost
• An influential and effective communicator
• Highly skilled at developing people, building high impact teams, and attracting top talent
• Strong proficiency with the software development lifecycle and engineering excellence processes, Agile methodologies, along with skills in leading moderately sized projects
• Technical savvy, allowing you to guide complex technical discussions, weighing the tradeoffs, and advocate for sound decisions
• A skilled operator of Agile practices and data driven methodologies
• Ideally, possess deep knowledge and experience with Microsoft languages/frameworks (C#/.NET, SQL Server, Entity Framework)
• Expertise with Azure (Function Apps, Service Bus, etc...) and DevExpress a bonus

Team Enablement & Mentorship:

• Mentor engineers, helping them grow into technical leadership roles
• Break down complex, ambiguous problems into actionable work that distributes effectively across the team
• Champion engineering best practices including observability, incident response, and production excellence
• Share your enthusiasm for tech trends, explore and learn new technologies

Cross-Functional Impact:

• Partner with Product and Customer Success teams to translate business requirements into scalable technical solutions
• Collaborate across distributed teams (Ireland, U.S., Philippines, Australia) to drive alignment on technical approaches
• Influence product roadmap by identifying technical opportunities that create competitive advantages
• Bridge the gap between technical implementation and business value, helping the team prioritize high-impact work

Maximize Agility:

• Identify and eliminate bottlenecks in the development lifecycle that slow down the entire team
• Drive adoption of modern engineering practices that improve developer experience and productivity
• Lead post-mortems and blameless retrospectives that turn incidents into learning opportunities

Ownership & Accountability:

• Own critical systems end-to-end, from design through production support
• Take responsibility for production reliability and proactively prevent incidents
• Step into ambiguous situations and drive them to resolution without needing explicit direction
• Make tough technical trade-off decisions and clearly communicate the reasoning

About Lumo

Lumo is Proton's privacy-first AI assistant that fundamentally reimagines how AI should work - empowering users without exploiting their data. Unlike traditional AI platforms that harvest user conversations for training and profit, Lumo operates with zero-access encryption, keeps no server-side logs, and ensures that conversations remain completely confidential.

Built by the team behind Proton Mail, Proton VPN, and backed by the nonprofit Proton Foundation, Lumo represents a paradigm shift in AI development. We believe the benefits of AI are too great to miss, but the privacy risks of current implementations are too serious to ignore. Lumo is based on open-source language models, operates from Proton's European datacenters, and provides unprecedented transparency in the AI space.

Our Mission: To deliver the full power of artificial intelligence while maintaining user privacy as an uncompromising core principle. We're building an AI that only works for you, not the other way around - where your conversations remain confidential and your data stays fully under your control, never shared, sold, or stolen.

Our Technology: Lumo implements multiple layers of encryption throughout the entire pipeline, from device-to-server communication through to long-term storage, creating a privacy architecture that's simply much stronger than anything else on the market. The platform runs on open-source models including Mistral's Nemo and Nvidia's OpenHands 32B, with full source code transparency.

Role Overview

We’re looking for an experienced Growth Manager to help drive the expansion of our B2B VPN business. While Proton VPN is already one of the world’s leading VPN services, our B2B offering is still in an early growth phase. You’ll play a key role in shaping its trajectory—defining product positioning, pricing strategy, acquisition channels, and sales loops.

This is a hands-on, strategic role that calls for both analytical thinking and a strong sense of curiosity about technology. It’s also a high-visibility, cross-functional position—you’ll collaborate closely with teams across Product, Marketing, Sales, Customer Success, and Data on a global scale.

What You’ll Do

• Growth strategy: own the end-to-end B2B growth strategy for Proton VPN. Identify high-impact growth levers across channels, define KPIs, and execute scalable, data-driven campaigns that drive qualified leads and self-serve subscriptions for Proton’s VPN for Business product.
• Inbound: design full-funnel marketing programs, including paid acquisition, SEO and CRO, in collaboration with our central Marketing team.
• Outbound: build outbound campaigns from the ground up.
• Content & thought leadership: develop a content strategy that positions Proton as a trusted authority in online security and privacy for businesses, in partnership with Marketing, Product and Sales.
• Analytics & reporting: define and track key marketing performance indicators. In collaboration with our Data team, build our analytics stack.

What You'll Bring

• 2–10 years of experience in a fast-growing B2B environment, whether in a marketing / growth role or in a strategic role. Experience with self-serve and / or sales-led acquisition.
• You need to be hands on. Proton’s culture is not corporate, and we expect our leaders to lead from the front.
• Analytical and data driven. This is important at Proton, and we welcome candidates with scientific or engineering backgrounds who now work in marketing or growth.
• Cost-efficient mindset. Proton is a bootstrapped startup. We’re creative and efficient, because that’s how we will win in the long run.
• Not necessary, but valued: proven track record of driving revenue through outbound sales.
• Not necessary, but valued: experience building teams and processes from scratch, since Proton is just starting in B2B.

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.

About Behavox

Behavox is a cloud-native AI company providing an integrated controls platform for global banks, asset managers, hedge funds, private equity firms, insurance businesses, and commodity firms. The platform unifies communications and trade surveillance, compliant archiving, policy management as well as front-office analytics on a single, AI-native technology stack, delivered as a globally scalable SaaS-based cloud service.

At Behavox, our engineering culture is built around speed, experimentation, and technical excellence, following agile principles and rapid iteration. We constantly test and adopt the latest cloud technologies and AI tooling, optimising for fast feedback loops and execution. We look for people who can move fast, challenge conventional wisdom, and who want to work at the frontier of modern AI, SaaS platforms, and distributed systems.

Behavox is a high-performance organisation with a strong bias toward delivery, ownership, and responsibility. We commit, and we execute. We are building systems that are complex, mission-critical, and global in scale; systems that many consider too large or too difficult. To do that, we seek the smartest, most technically capable engineers and technologists who take end-to-end responsibility and want to win by building what others cannot.

Founded in 2014 and backed by SoftBank Vision Fund, Behavox is headquartered in London, with offices worldwide, including New York City, Montreal, Seattle, Singapore, and Tokyo.

About the Role

The Senior Enterprise Account Executive is responsible for driving revenue growth within a named portfolio of strategic enterprise accounts aligned to one of Behavox’s core verticals: Banking and Capital Markets, Asset and Wealth Management, Private Equity, or Commodities. The role focuses on new business acquisition and expansion within highly complex customer environments, managing larger deal sizes involving broader buying groups, multiple business units, and higher organizational complexity than BCL3 roles, while maintaining ownership of selective renewals within their account set.

This role owns the full commercial sales lifecycle for strategic accounts, including AE-led outbound prospecting, opportunity shaping, value articulation to both above-the-line business stakeholders and below-the-line functional buyers, commercial negotiation, and contract execution for the Behavox Controls Platform. The Senior Account Executive is accountable for shaping and advancing the commercial value case by aligning customer strategic objectives, economic outcomes, and executive priorities to the buying decision, and for maintaining durable executive relationships across complex stakeholder environments. The role operates with greater autonomy over deal strategy, stakeholder navigation, and commercial sequencing while executing within established go-to-market strategy and commercial frameworks. Disciplined pipeline management, forecasting accuracy, and sales hygiene in HubSpot are required to support predictability across a strategic book of business. Following initial contract signature, the role retains commercial ownership of the account and partners with Customer Success to drive value-led expansion and renewals.

What You'll Do

1. Strategic outbound prospecting and pipeline ownership – Owns outbound pipeline generation within a strategic named account portfolio, with heavy reliance on direct AE-led prospecting and partnership with SDR and Marketing to engage senior executive and functional stakeholders across business units.
2. Complex enterprise deal leadership – Owns end-to-end commercial execution for large, complex opportunities involving multiple buying groups, setting deal strategy, stakeholder engagement plans, and negotiation approach through close.
3. Executive-level value-based selling – Owns the articulation and progression of a strategic value case for the Behavox Controls Platform by linking enterprise objectives, economic impact, and executive priorities to the buying decision.
4. Advanced commercial negotiation, deal governance, and CRM hygiene – Leads complex pricing and commercial negotiations, structures non-standard deal terms within approval frameworks, and maintains high-fidelity pipeline, activity, and forecast hygiene in HubSpot.
5. Strategic post-signature account ownership – Retains commercial ownership after close, maintaining executive relationships and working with Customer Success to identify, scope, and close expansion opportunities across business units.
