Senior SMS Manager

We are hiring on behalf of our client — an American media company with an office in Warsaw. They own and monetize a large newsletter portfolio across finance, health, and business verticals, sending to millions of subscribers in the US. SMS is their next major revenue channel, and nothing exists yet. This role builds it from scratch.
 

The role

This is a full ownership role for someone who has launched SMS programs at scale and knows how to turn a subscriber list into a revenue line. You will design the infrastructure, build the opt-in strategy, own the monetization, run the content operations, and hire a team as the channel grows.

You will not be inheriting an existing program. You will not be coordinating vendors. You will be the person who decides how this is done and executes it directly, with full access to leadership and real resources behind you.
 

What you will own

• SMS infrastructure: platform, vendor ecosystem, sending architecture, segmentation, and message routing
• Opt-in strategy and subscriber growth across newsletter properties, web, and email
• Deliverability, sender reputation, and performance metrics
• Full subscriber lifecycle from opt-in through churn
• SMS content calendar, copy standards, and editorial coordination
• SMS advertising product: rate card, inventory, targeting, advertiser reporting
• TCPA, GDPR, and carrier compliance end to end
• Team building as the channel scales
   

Must-have

• 5+ years in SMS marketing or mobile messaging, at least 2 at high-volume scale
• Proven track record launching an SMS program from scratch — not inheriting an existing channel
• Hands-on experience with a major SMS platform: Klaviyo, Attentive, Postscript, Twilio, or comparable
• Experience building and selling SMS advertising inventory: rate cards, targeting, advertiser reporting
• Deep compliance fluency: TCPA, GDPR, CTIA — lived and enforced, not listed
• Experience hiring and managing a small team
• Data-driven: tracks everything, reports clearly, decides from numbers
• C1+ English, written and verbal
   

Nice to have

• Background in newsletter, media, affiliate, or performance marketing
• Experience with workflow automation tools: Make, Zapier, or similar applied to messaging ops
• Familiarity with A/B testing applied to copy, send timing, and opt-in conversion
• Technical fluency with APIs, webhooks, or basic scripting for platform integrations
   

Compensation and benefits

• Competitive salary + bonuses
• 21 paid vacation days, 15 paid sick days
• Remote or hybrid, Warsaw office
• B2B contract, company covers taxes
