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

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.
