• Experience testing native or cross-platform SDKs
• Familiarity with Android (Kotlin/Java) and/or iOS (Swift) enough to read stack traces or sample integration code

• Work with a cloud stack, message queues and APIs

You should have
• 3+ years of Go in production and 5+ years of backend work overall. If you come from a strong product team and work in another language, apply anyway and tell us how fast you would pick up Go
• Experience owning parts of a production system end to end
• Fluent English for daily work with the client team

The role is full time, 40 hours a week, long term, with a working day that overlaps European business hours. Individual engineers only, no agencies.

How we hire: a call with our CTO about your product work and your code, then a call with the client's team. Both are live, with screen share and without AI assistants.

To apply, open your application with a link to a product you helped build and one sentence on what you owned in it. Applications without it will not be read.

Cloudfresh powers growth for 2,500+ clients in 70+ markets across Cloud, Cybersecurity, CRM, Collaboration, DevSecOps, and Data & AI. We partner with Google Cloud, Chrome Enterprise, Microsoft, HubSpot, Zendesk, Asana, Miro, GitLab, Okta, JumpCloud, Cloudflare and Wiz.

We’re looking for a User Acquisition Manager to own how new customers find Cloudfresh. Not one ad account. The whole engine. Running campaigns is part of it. The bigger job is deciding where the next qualified buyer comes from across channels, vendors and markets, and proving it in pipeline.

What You’ll Do

• Own paid acquisition end to end. Google Ads, LinkedIn, Meta and whatever channel earns its budget next.
• Reallocate budget every month across vendors, regions and channels based on CAC and pipeline. Cut what doesn’t pay back.
• Build and test landing pages, offers and retargeting flows. Grow conversion rates quarter over quarter.
• Run weekly tests on audiences, creatives, bidding and messaging. Keep a shared log of what worked.
• Set up tracking from ad click to closed deal in HubSpot. Report pipeline and revenue by campaign, not just leads.
• Drive registrations and pipeline for events, from webinars to our own events. Bring in real attendees who convert into deals, not just sign-ups.
• Use AI tools and agents to automate reporting, QA, competitor monitoring and campaign analysis.

• Agree on ICP, lead quality criteria and SLAs with marketing and sales teams. Review lead quality together every month.

   

What You Bring

• 3+ years in paid acquisition or growth, with B2B SaaS or tech experience
• Hands-on mastery of Google Ads and LinkedIn Ads. You’ve managed real budgets and can show results
• You think in pipeline and CAC, not CTR
• Strong analytics: GA4, Looker Studio or similar, plus AI tools to analyze data, spot patterns and build reports faster
• Experience with HubSpot or another CRM and marketing automation
• You’ve built and tested landing pages, not just briefed them
• You already use AI tools in your daily work and want to push further

• English at B2 or higher

   

Nice to have:

• Experience marketing cloud, security or IT products
• Multi-market campaigns across Europe, the Middle East or Central Asia
• Partner or channel marketing experience
• ABM tools and intent data

• Basic SQL or scripting for ads automation

   

Our Values

1. Customer First. Your success is our purpose.
2. Own the Outcome. We see it through.
3. Direct & Human. Honest, open and caring.
4. Raise the Bar. We never settle for “good enough”.

5. Generate the Real✨ Our DNA.

    

What We Offer

• Build your cloud marketing expertise with Google Cloud, Chrome Enterprise, Microsoft, HubSpot, Zendesk, Asana, Miro, GitLab, Okta, JumpCloud, Cloudflare and Wiz.
• Lead meaningful campaigns across EMEA, making an impact in diverse and dynamic markets.
• Bring your ideas to life in a culture that values creativity and is open to new approaches.
• Enjoy a competitive salary and a transparent bonus system tied to your results.
• Work flexibly remote or join us for a coffee in Kyiv or Prague offices.
• 24 vacation days, bank holidays, and 14 days sick leave.
• Medical insurance for team members in Ukraine.
