CRM & Lifecycle Marketing Lead (B2B & B2C)

 

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 700+ 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. Check our open-source projects here.

The Role

As we scale both our B2B and B2C businesses, CRM and lifecycle marketing are becoming critical growth engines. We’re looking for a CRM & Lifecycle Marketing Lead to join our Growth & Lifecycle Team to own, unify, and scale lifecycle strategy and operations across both segments.

This is a senior individual contributor role — with the expectation of building a team over time — for someone who can set a lifecycle strategy and build it themselves. You'll own Proton's end-to-end CRM and lifecycle programs across B2B and B2C, translating growth and product strategy into automated, measurable lifecycle systems and operating as the single lifecycle authority across the company.

Both platforms are live - your job is to take them from functional to fully operationalised. Vero runs B2C and HubSpot runs B2B; the architecture exists, but the programs, automations, and customer journeys that drive conversion, retention, and revenue at scale are yours to build.

You'll be equally comfortable designing a lifecycle framework, configuring the platform that runs it, and digging into the data to prove it works. You know what events, attributes and signals each program needs, and you work closely with Data and MarTech teams to deliver the right journeys. You operate through influence and systems ownership rather than headcount - and you've done this before in an environment where there's no program management layer and no one to hand problems to.

 

What You’ll Do

Lifecycle strategy (B2B & B2C)

• Own end-to-end CRM and lifecycle strategy across both segments.
• Define and operationalise the core frameworks: onboarding, activation, retention, churn prevention, upsell, cross-sell, expansion and win-back.
• Embed lifecycle thinking across Marketing, Product and Growth.

B2B CRM & marketing operations (HubSpot)

• Take Proton’s existing HubSpot Marketing Hub setup from early-stage to mature, fully operationalised use.
• Build and scale B2B lifecycle architecture on top of it: lead capture and qualification, MQL→SQL orchestration, and segment- and intent-based nurture.
• Establish clean lifecycle-stage definitions, robust lead scoring, and reliable automation where these are still immature.
• Own CRM data hygiene, governance, and compliance.

B2C Lifecycle & Monetisation (Vero)

• Own B2C lifecycle communications from activation through retention, driving CLTV, reducing churn, and improving conversion in partnership with Product, Growth, and Design.
• Use customer segmentation to ensure every lifecycle communication reaches the right person at the right moment, continuously refining audiences.
• Design and manage campaigns across email, in-app, and later push notifications that are aligned to the growth and marketing calendars and commercial goals.
• Run a structured test-and-learn program (A/B, MVT) in partnership with Data Analytics, turning results into measurable improvements in engagement and conversion.
• Maintain a clear optimisation roadmap and own channel KPIs — tracking what’s working, fixing what isn’t and documenting what scales.

Data & Enablement

• Define the data foundation lifecycle marketing runs on. Work with Analytics to identify the product events, user attributes and behavioural signals each program needs to perform.
• Work with Data Science to bring predictive models into production lifecycle use cases: churn propensity, upsell triggers, engagement scoring.
• Act as the business voice into the Martech team, surfacing lifecycle pain points, defining the outcomes new capabilities need to deliver, and signing off on what’s built.

Reporting & optimisation

• Work with Data Analytics to produce dashboards and reporting that give Marketing, Sales, Product, and Leadership clear visibility into lifecycle performance.
• Use experimentation and insight to continuously improve.

Cross-functional leadership

• Act as the connective tissue between Marketing, Sales, Customer Success, Product, Data, and Engineering — aligning everyone around a single customer view.
• Ensure CRM and lifecycle workflows fit how teams actually operate.
• Enable stakeholders on lifecycle best practice and CRM discipline, and build the documentation, standards, and processes that scale with the company.

What You’ll Bring

• Significant experience in CRM, lifecycle marketing, or marketing operations spanning both B2B and B2C.
• Deep, hands-on expertise with HubSpot CRM and Marketing Hub and event-based lifecycle tools such as Vero (or close equivalents) — you configured and run these yourself.
• A track record of taking early-stage lifecycle implementations to maturity and scaling them, ideally in a startup or scale-up environment.
• Strong command of B2B sales and marketing alignment (MQL/SQL, pipeline, handoff) and subscription-based consumer retention and monetisation.
• A strong grasp of the data behind lifecycle marketing: you know what data points a program needs, can specify and request them from Data/Martech teams and understand how product events and attributes flow into CRM platforms without needing to build the pipelines yourself.
• Highly analytical and commercially minded, comfortable with behavioural segmentation and experimentation.
• Proven ability to operate independently in a matrix organisation and influence without direct authority — a self-starter who commands respect through expertise and delivery.
• A systems thinker who enjoys building scalable foundations in a privacy-first environment.
