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.

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.
• 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.

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 Bring

1. Executive enterprise buying dynamics – Deep knowledge of how senior executives in large, regulated financial institutions evaluate strategic investments across multiple business units and stakeholder groups.
2. Advanced vertical business and regulatory context – Strong understanding of the business models, regulatory pressures, and control challenges shaping strategic priorities within the assigned industry vertical.
3. Behavox Controls Platform strategic value – Knowledge of how the platform supports enterprise-wide risk, compliance, and operational objectives, and how that value is positioned to executive and business unit leaders.
4. Complex multi-stakeholder deal economics – Knowledge of high-value enterprise sales involving multiple buyers, budget owners, and approval paths across business units.
5. Strategic account lifecycle management – Understanding of how executive alignment, cross-business adoption, and commercial stewardship support sustained growth within strategic accounts.

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.

What We Offer

• The opportunity to work on a global, mission-critical AI platform alongside the best engineers and technologists across multiple geographies.
• A role with real ownership and impact, building complex systems at scale in an environment that values speed, experimentation, and technical excellence.
• A highly attractive benefits package, including competitive cash compensation, an equity award aligned with long-term value creation, and comprehensive health insurance for employees and their families.
• A generous time-off policy of 30 days annually, plus public holidays and sick leave, recognising the importance of sustained high performance.

About Our Process

We take Talent very seriously and we are building a community of extraordinary individuals working together in very high performing teams. We also know that the best Talent always has options so we believe that the process has to be a two way assessment - the company AND the candidate assessing the business needs alignment, the career next step alignment, and the cultural alignment. 

During the process we will begin by exploring the core factors regarding salary and location along with core experience and skills and values alignment. We will then deep dive explore the critical technical competencies we have identified for the role, and then we will deep dive in behavioral competencies.

The most aligned candidate will then be asked to do a practical work task simulation activity so we can make sure that you will enjoy the kind of work the role requires, and this task will typically be presented and discussed with a group of colleagues and managers. Finally we will ask you to meet with a number of our senior leaders to make sure that you are making the most informed call possible.

Please note that:

• We want to get to know you and have a genuine conversation, so the use of AI tools or assistance during live interviews is strictly prohibited and will result in immediate disqualification from the process 
• Interviews may be recorded for internal review purposes to ensure fairness and enable collaborative hiring discussions within the team.
