This is NOT a traditional marketing role.

We’re not looking for someone who spends the whole day manually writing captions, filling content calendars, and repeating the same routine tasks every week.

We’re looking for a marketer first — but one who works in an AI-first way.

Someone who understands marketing, content, creative strategy, testing, and execution — and uses AI as a core part of how they work.

Someone who sees a marketing task and immediately thinks:

• how can I find a stronger angle?
• how can I test this faster?
• how can I get to a better result with AI?
• how can I increase quality and speed without losing taste?

About us

TICKETS is built by the bxnda.com team — a travel-tech company creating and scaling flight ticket aggregators across 80+ countries worldwide.
 

We move fast, test a lot, and care about what actually works. This is not a corporate environment with layers of approvals and slow execution. It’s a startup team focused on speed, ownership, and real outcomes.
 

We’re looking for an AI-First Marketer who understands how modern marketing works and wants to use AI as a core part of that work — to create better content, test more ideas, move faster, and improve performance across a global audience.

What you’ll do

• Create and improve marketing output for social media, ads, landing pages, emails, and other growth needs
• Research, brainstorm, and develop ideas with AI tools
• Test formats and creative directions quickly
• Improve the quality of content and creative execution, not just the speed
• Work with the team to turn raw ideas into strong marketing output
• Use AI to reduce routine work and focus more on judgment, ideas, and execution
• Stay on top of new tools, models, and workflows that can improve marketing performance

What we’re looking for

• 1+ year of relevant experience in marketing, content, creative strategy, social media, copywriting, growth, or a related area
• At least 3 months of real hands-on experience using AI tools in daily work
• Understanding of marketing fundamentals: audience, messaging, angles, content, creative, testing
• Ability to tell what is strong, weak, generic, or off-target
• Fast learner with initiative and ownership

Nice to have

• Experience with ChatGPT, Claude, Midjourney, Runway, CapCut, Make, Zapier, Notion AI, Airtable, or similar tools
• Experience creating content or campaigns for TikTok, Instagram, Pinterest, UGC, paid creatives, or performance marketing
• Experience using AI for research, ideation, scripting, copy, visuals, or campaign development
• Understanding of how to keep AI output useful, sharp, and non-generic
• Startup mindset
  
  
  What we offer

🏢 Office-based role in Warsaw

Lemon.io is a curated marketplace that connects startups and scaleups with pre-vetted senior software engineers. Founded in 2015 in Kyiv, the company has grown to 60+ people, 1,500+ vetted developers across 40+ countries, and ~2.3 million cumulative work-hours logged on the platform. 
The business runs on one core bet: the quality of talent matching defines everything. 

Tens of millions of profiles carry signals that are mostly underused for understanding who will fit best for what job. We're hiring our first engineer to change that. This person will own a brand-new internal data platform from zero: designing and building how we gather, structure, and surface developer intelligence so the business can match faster, smarter, and at scale.

This is a founding, senior/staff-level role. You won't inherit a codebase or join a squad – you'll make the architectural decisions, pick the stack, and ship the first version. You'll work directly with stakeholders across whole org to understand what data matters most and build the system that makes it valuable.

EU timezone preferred. Remote.
 

Must-have:

• Hands-on experience building data/platform products (not just consuming data – creating and designing how it's collected, structured, and served)
• At least one 0 -> 1 greenfield build – took something from "nothing exists yet" to a working system in production
  Strong backend foundation – can make architectural decisions and own them
• English B2 or higher
• Strong written and verbal communication – can articulate technical decisions to non-technical people and drive alignment async
• Data pipeline design and implementation – ingestion, cleaning, enrichment, serving
• Search and indexing systems (Elasticsearch or similar)
• Relational databases (PostgreSQL or similar)
• Cloud infrastructure (AWS, GCP, or Azure) – can provision and operate services independently
• System architecture – can design a platform from scratch and make defensible trade-offs

Nice-to-have:

• Track record of working directly with non-technical stakeholders (product, ops, leadership)
• Reasonable infrastructure experience
• ML/AI experience (embeddings, NLP, classification)
• ETL orchestration tools (Airflow, dbt, Dagster)
• Data warehouse experience (BigQuery, Snowflake, Redshift)

What you'll get:

• Startup culture with open communication. Our current eNPS score is 82. 
• Competitive salary in USD
• Full remote work with flexible working hours
• 28 working days of vacation a year
• 7 days of sick leave
• Annual reimbursements for things that matter to us: health, self-development, travelling, home office upgrade, mental wellness etc.
• Help with maintaining your Ukrainian PE.
