About Proton

Join Proton and build a better internet where privacy is the default 

Proton is one of Europe’s fastest growing scale-ups, serving more than 100 million users around the world. Since the launch of our first service, Proton Mail, in 2014 by scientists who met at CERN, Proton has grown into the first of its kind privacy-first ecosystem of services such as Proton VPN, Proton Drive (encrypted file storage), Proton Pass (encrypted password manager) and much more.

Our mission is to build a more ethical and responsible alternative to Big Tech services, with a focus on end-to-end encryption, privacy, open-source and ease-of-use. Our user-first approach has helped Proton grow organically to serve millions of consumers and businesses around the world, from newsrooms, activists, and international organizations  like The Guardian, The New York Times and the UN to authors, Nobel-prize winners, and movie characters. Proton is trusted and supported by over 100 million people who believe privacy and freedom online are worth protecting.

Proton does not have venture capital investors, is profitable and self-sufficient, and today has over 600 employees representing over 40 nationalities. We're headquartered in Geneva, Switzerland, with additional offices in Zurich, London, Paris, Barcelona, Taipei, Skopje, Vilnius and Prague.

As one of Europe's fastest-growing companies, we offer the chance to tackle complex challenges, influence millions and shape a more equitable internet. We want to create more than just one of the world's most impactful tech companies: we want to create a new internet that serves the interests of all people. We need you, your voice, your ideas and your ambition to make it happen.

The Role

Proton’s community loves swag, and we need you to help us take it to the next level! In this role, you’ll build and scale Proton’s custom merch shop for fans, supporters, ambassadors, partners, creators, and conferences. You’ll own the end-to-end strategy—from product and collection planning to production, storefront performance, and customer experience.

You’ll lead our merchandising roadmap: defining always-on staple items, seasonal collections, and limited-edition collectibles with clear launch mechanics, upsell paths, and inventory plans. You’ll manage inventory across multiple internal use cases (gifting, events, partnerships) while ensuring production, supply chain, and fulfillment meet the highest standards—balancing quality, timelines, and cost efficiency through strong vendor management and negotiation.

The ideal candidate combines strong taste and creativity with crisp communication, operational excellence, and a data-informed mindset.

The Team 

This role is part of the Social & Community team at Proton - a small, high-impact group of 5 people that builds Proton’s brand the way modern cult brands do it: with a human voice and sharp, timely creative that people actually want to share. We move fast, take principled stances when it matters, and pair rigorous performance thinking with internet instincts, earning the kind of audience feedback most brands never get (“genius level trolling,” “10/10 Proton marketing team,” “great marketing,” “social media masterclass,” “best repost I’ve seen in a while” “deserves a raise”) or getting compared to Wendy’s. 

You’ll help us break out of online-only marketing and build community relationships in the real world. Through thoughtful drops, high-quality staples, and strategic gifting, you’ll strengthen brand perception, spark word-of-mouth, and create shareable IRL experiences that fuel UGC and community storytelling online.

If you want to do career-defining work with a team that’s trusted to experiment, backed by a mission people care about, and measured on real impact, you’ll fit right in.

What you’ll do

• Propose and run experiments (pre-orders, waitlists, personalization, tiered perks, limited-access drops, bundles, collaborations).

Brand consistency and awareness

• Drive brand awareness and community delight through merch moments, creator seeding, and fan engagement.
• Develop programs to generate UGC (campaign prompts, incentives, repost flows, ambassador collaborations).
• Partner with Social & Community to translate cultural moments and product launches into merch that travels organically.

Gifting platform and multi-stakeholder inventory

• Own Proton’s gifting platform operations and stock planning across use cases (employees, partners, influencers, ambassadors, VIPs, press).
• Build workflows for requests, approvals, fulfillment, tracking, and reporting (including cost attribution where needed).

Communications and go-to-market

• Build communication plans for launches and always-on shop promotion (email, social, community, partners, PR hooks as relevant).
• Align creative, messaging, and timing across teams; ensure launch readiness and clear operational runbooks.

Shop performance and operations

• • Own e-commerce KPIs: conversion rate, AOV, revenue, returning customer rate, email performance, and retention.
  • Own day-to-day shop operations: product setup, inventory hygiene, fulfillment coordination, returns/refunds processes, customer support SLAs, and escalation paths.
  • Onboard and train customer support agents to support after-sale operations like refunds, exchanges, feedback, and complaints. 
  • Ensure compliance and operational correctness (tax/VAT where relevant, shipping rules, data handling, vendor contracts).

Job Requirements

• 4+ years in e-commerce, merchandising, or DTC operations (bonus if paired with community-led growth).
• Proven track record owning an e-commerce channel end-to-end: strategy, launches, inventory, and performance optimization.
• Hands-on experience with merch production workflows (sourcing, sampling, MOQs, lead times, QC).
• Experience with Shopify (or similar), fulfillment logistics, and customer support tooling.
• Basic knowledge of design programs like Adobe Illustrator, Figma, Indesign, or similar 
• Proven communication and copywriting experience for e-commerce content
• Professional proficiency in English, another European language is a plus

Bonus points for

• Experience with e-commerce and gifting for a fast-scaling tech or SaaS company
• Passion for privacy tech, mission-driven brands, internet culture, and community-first marketing.

We'd expect you to breathe and live data, to thrive for knowledge and excellence, and to be keen to build something enduring and impactful for our customers. We'd expect you to be a (data) Paoneer!"  (Máté Gulyás, CEO)

What will you do?

As a Senior Data Engineer, you are expected to deliver (across industries) on some of our most complex projects - individually or by leading small delivery teams. Although we work for the biggest multinational companies where years-long behemoth projects are the norm, our projects are fast-paced, typically 2 to 4 months long. Most are delivered using Apache Spark/Databricks on AWS/Azure and require you to directly manage the customer relationship alone or in collaboration with a Project Manager. Additionally, at this seniority level, we expect you to compound your impact across the team and the organization - by supporting our pre-sales process, mentoring more junior engineers, and contributing to hiring best-in-class data talent.

What does it take to fit the bill?

• Fully paid Medical Leave for up to 15 days per year - because when you’re unwell, we want you to focus on recovery and not worry about your paycheck;

• Comprehensive private health insurance plan via Allianz - offered via our EOR (Employer of Record) provider, Remote.com. Remote will be your official employer in Spain for the foreseeable future until we establish our own legal entity in Spain;

• Employee Assistance Program (EAP) via Allianz & Remote - life always happens! And we'd like to be there for you when it counts the most. Through EAP, we offer our employees access to psychology, financial, and legal consulting services via phone or in person;

• Top-notch working equipment - working comfortably means working well. You will get a MacBook Pro and a sign-up bonus of 500 EUR gross (to be paid with your first payroll) to set up your home office or whatever else is needed to give your best;

• The chance to make an impact in a high-transparency culture - open feedback and no politics are things we value a lot at DATAPAO. Additionally, you'll get the chance to work in the field of data & AI and shape the future of a rapidly growing tech company.

IMPORTANT NOTE: Given that we are still sorting our way in Spain, this list will likely get an update in the following months, and we're also committed to growing it with us over time.

The gross salary for this position ranges from 70.000 to 80.000 EUR/year, depending on your assessed seniority level during the selection process.

Please note that currently we are unable to support transfer or offer full sponsorship for Skilled Worker visas as we’re just setting foot into Spain.
