Marketing Lead (SEO & Growth) to $2500
 

Who We Are Looking For: We don't need a task executor or a report-forwarding manager. We need an A-player — someone who takes full ownership of marketing and treats results as a personal responsibility. You'll be a stakeholder in the project, not just an employee.
 

Your Responsibilities:

• Build and execute the overall marketing strategy from scratch
• Own SEO — content planning, programmatic pages, link building, AI-driven content ops
• Drive lead generation through outreach, partnerships, and new channels
• Communicate directly with leads and partners — you represent the company's growth
• Generate ideas, run experiments, and kill what doesn't work

Requirements:

• 2-3+ years in marketing, ideally in a startup or agency environment
• Proven SEO track record — you've grown organic traffic, not just tracked it
• Experience communicating with leads or clients — confident, clear, and conversion-focused
• Self-driven with a bias for action — you don't wait to be told what to do
• English: Upper-Intermediate or higher
• Aligned with startup values: speed, ownership, and no bullshit

What You Get:

• Fully remote, flexible schedule, focus on results not logged hours
• Real ownership — your decisions shape the direction of the product
• Zero bureaucracy — direct communication with the founder, decisions in minutes
• Creative freedom to test bold ideas as long as they deliver ROI
• A chance to grow the new project from $1K to $10K MRR — and be part of that story
• Compensation: up to $2,500/month depending on experience

Workload: full-time
Location: preferably EU (but if the candidate has a good match other countries can be considered as well)
Start: within a couple of weeks
Duration: 6 months with a potential prolongation
English: B2
