Localization Manager

Proton was founded in 2014 by scientists from CERN on a simple truth: privacy is a fundamental human right. Since then weve built the worlds 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 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 700 team members from 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. Check our open-source projects here.

• Own the lifecycle for your portfolio. From string freeze to general availability initiation planning execution closure. Coordinate Product Design Engineering Marketing and Support against fixed release dates and be the person who knows whether a locale is actually ready to ship.
• Run the machine. Administer our TMS and CAT workflows keep handoffs clean between stakeholders and maintain the assets that make repeatable launches possible: scoping models timelines locale-readiness checklists go/no-go criteria.
• Keep your spend on track. The Localization Lead owns the budget; you look after your corner of it. Track translation costs per product and per language reconcile monthly and flag drift while its still cheap to correct not after it becomes an overrun that needs explaining.
• Build and manage the vendor bench. Recruit pre-qualify and test suppliers and freelancers for your portfolio; maintain SLAs NDAs and documentation; track quality and turnaround; run quarterly business reviews. Escalate to the Localization Lead and pull in Legal and Finance when a blocker needs them.
• Ensure adaptation not transliteration. Growth-facing content CRM and lifecycle email flows campaign landing pages marketplace listings pricing signup and feature messaging gets rewritten for the market not converted word for word. You brief and review the adaptation and you flag cultural and regulatory risk before release. Where your portfolio includes lifecycle email you also own its template internationalization and content logic.
• Be the reference point. You are the linguistic and internationalization contact for your stakeholder group Product Managers UX Writers Marketers Developers and Support and you raise the bar beyond it through retrospectives corrective-action reports and the occasional proof of concept.
• Ship experiments then measure them. With the CRO team execute localized variants and campaign content inside your portfolio. As the area grows you take on more: framing localization hypotheses interpreting results within the growth teams experimentation framework and segmenting funnel data by locale with Product Analytics to find where language and culture cost us conversions.

• Youve owned localization projects or programmes end-to-end including multi-workstream multi-market launches against dates you couldnt move.
• You work in English daily (B2C2) and you have native or professional working proficiency in at least one other language. Any language counts what were really testing is whether youve lived long enough inside a second language to tell copy that sounds native from copy thats merely correct.
• You can administer TMS and CAT tools hands-on and you know localization best practice and internationalization standards well enough to argue about them.
• Youve managed vendors and freelancers against quality turnaround and cost targets and youve watched a spend line closely enough to catch it moving before anyone asked you to.
• Youre comfortable with operational data: you define the right metrics watch them and change behaviour when they move.

• Hands-on experience running or contributing to A/B tests on localized surfaces.
• Localization inside a CRM or marketing-automation platform (transactional and lifecycle email template logic).
• Experience supporting consumer and B2B product surfaces in the same portfolio.
• Exposure to MTPE pipelines quality estimation or automated LQA gating.
• Localizing content with regulatory stakes legal updates privacy disclosures terms.
