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.
Co budeš dělat
- Be part of end-to-end experiment scoping and preparation by helping write and refine hypotheses, draft experiment briefs, align with the team on primary metrics and key guardrails, and translate requirements into the landing page/page-variant updates needed ahead of launch.
- Work in close alignment with the Data/Analytics team to review funnel performance, understand drop-offs and bottlenecks, and translate insights into prioritized test ideas and clear next actions.
- Coordinate with Product, Engineering, and Analytics to align on measurement needs (events, tracking plans, tagging assumptions, dashboards) so experiment readouts are reliable and consistent.
- Partner with Design, Content, and marketing channel owners to adapt landing page messaging and structure to match traffic intent and channel needs (Organic, Performance Marketing, Affiliates, and Influencers).
- Create, iterate on, and QA landing pages and experiment variants in the page/content publishing workflow, ensuring consistency across devices and key entry points.
- Document experiment outcomes, decisions, and learnings in a structured way so insights compound over time and enable faster iteration across future tests and teams.
Koho hledáme
- An experimentation mindset: you are curious, structured, and guided by a user-first mindset, focusing on measurable improvements across acquisition, sign-up, checkout, and upgrade funnels.
- 1 to 3 years of experience in conversion rate optimization and experimentation, with exposure to at least one of the following areas: growth, lifecycle, or performance marketing, and clear examples of measurable conversion impact.
- Ability to translate insights into clear hypotheses, define primary metrics and guardrails, and support A/B tests through launch, QA, and readout.
- Solid analytical foundations: comfortable reviewing funnel performance, spotting drop-offs, and turning results into prioritised next actions with Data/Analytics.
- Tracking and measurement literacy: able to align with Product and Engineering on events, tagging assumptions, and dashboards so results are reliable.
- Hands-on landing page optimisation: build, iterate, and QA pages and variants in a CMS/page builder, with strong attention to detail across devices.
- Strong cross-functional collaboration and documentation: coordinate with Design, Engineering, Product, and channel owners, and document learnings so iteration gets faster.
