Martech Manager at Roamless in Madrid, Community of Madrid, ES

About Roamless

The origin story of Roamless is one that will be familiar to many: we saw something broken and we decided to fix it for good.

We all travel. We all need to stay connected. And we all hate roaming charges. Existing alternatives were clunky, expensive, and unreliable, so we built something better. We made it easy, reliable and affordable for travellers to get connected and stay connected as they roam the world.

Our truly global mobile connectivity service is up to 90% cheaper than traditional roaming. With one eSIM, you get instant, reliable data anywhere in the world. No SIM swaps, no hunting for Wi-Fi, no choosing countries or data packs. Your balance never expires, so you can use it across trips with zero hidden fees or expiration dates.

In just 3 years, we've grown 4-5x Year on Year and have been trusted by +1M users who overall rate us 4.6 on Trustpilot.

🚀 We also recently closed a $12M Series A led by Rasmal Ventures, with participation from Shorooq, Revo Capital, Finberg, and JIMCO, to fuel our mission of becoming the world's first truly global mobile operator.

Hiring globally and fully remote, we're a team of 60, and we're planning to grow to 100+ in the next ~12 months.

About the role

Roamless has 1.5 million users and is growing 4–5x year on year. Every paid acquisition campaign, every cohort analysis, every A/B test depends on accurate marketing data and right now, no single person owns the stack. Attribution flows through AppsFlyer, Meta CAPI, GTM, OneSignal, and a growing list of tools. Events fire. Sometimes correctly.

This is the problem you'll fix. As our first dedicated Martech Manager, you'll be the bridge between the growth team and engineering. The person who knows exactly how data moves through our stack, who makes the calls on which tools we use and how they're configured, and who holds the bar on implementation quality.

You'll inherit a backlog of events and tags to be set up across web, iOS, Android, and backend. You'll design the architecture, spec the requirements, QA the output, and build the foundation that powers everything from our paid channels to our CRM lifecycle engine.

You'll work closely with our Growth, Engineering, and Product teams.

What you will do

• Own the marketing technology stack: evaluate, choose, and implement tools across the full stack (MMPs, tag managers, CRM integrations, conversion APIs, analytics)
• Define integration requirements for every platform: web, iOS, Android, and backend with clear specs that developers can actually build from
• Set up and maintain GTM (web and server-side) events and GA4 tags across all touchpoints; manage UTM taxonomy across all paid channels
• Oversee mobile SDK implementation: in-app event tracking, deep links, and deferred attribution flows
• Own MMP configuration and validation: ensure MMP attribution is accurate, postbacks are firing, SKAN 4 schemas are correct, and data is trustworthy
• Build and maintain paid channel integrations: Meta Conversion API, promo code tracking, deep link management
• Ensure CRM data flows work end-to-end: events syncing from MMP into our customer engagement tools and other lifecycle tools
• Run integration QA: TestFlight-based mobile testing, dashboard validation, root-cause analysis when data looks wrong
• Coordinate across growth, product, and engineering: translate marketing needs into technical requirements and vice versa

What you will bring

Must-haves:

• 3–5 years in marketing technology, marketing operations, or growth engineering, ideally at a B2C product company. Experienced in a highly technical Revenue Operations role in B2B SaaS is also acceptable.
• Hands-on experience with a mobile measurement partner: AppsFlyer, Adjust, or equivalent including event configuration, deep link setup, and attribution validation
• Google Tag Manager implementation experience (web and/or server-side)
• Mobile SDK tracking experience across iOS and Android
• CRM integration experience: syncing event data into lifecycle tools (Braze, Klaviyo, OneSignal, or similar)
• Intermediate SQL experience: you can query event data, validate tracking, and catch discrepancies
• Strategic ownership mindset: you evaluate tools, make recommendations, and set requirements independently; you don't wait to be told what to do
• Startup mindset: you are comfortable with ambiguity, creating your own playbook, and you take end-to-end ownership

Nice-to-haves:

• Basic coding skills (Python, JavaScript)
• Meta Conversion API (CAPI) integration experience
• SKAN 4/iOS 14+ attribution modelling knowledge
• QA or testing background (manual or automated)
• Experience using AI tools for workflow automation and requirements writing
