About the Role

This is a hands-on, highly operational role for an energetic "doer" who isn't afraid to get their hands dirty with video content. We don't just need someone to set up target audiences—we need a versatile specialist who can take raw video materials, slice them into dynamic short-form ad creatives, add engaging subtitles, and adapt them to dynamic Meta ad formats.

You will target health-conscious individuals, biohackers, executive longevity seekers, and proactive patients in the U.S., turning complex medical science into engaging visual storytelling.

• Campaign Strategy & Setup: Build, launch, and manage direct-response Facebook & Instagram campaigns tailored to U.S. health/longevity target audiences.
• Ad Copywriting & Creative Execution: Draft punchy ad copy and design engaging visual concepts (images, video hooks, carousels) that communicate complex scientific concepts clearly.
• Audience Targeting & Funnel Management: Segment and test audiences (custom, lookalike, retargeting, interest-based) and ensure tracking via Meta Pixel and Conversions API (CAPI).
• A/B Testing & Optimization: Continuously test video hooks, headlines, CTAs, and landing pages to reduce CAC and maximize ROAS.
• Performance Reporting: Track key indicators (CPA, ROAS, CTR, CPM) and provide clear insights during team syncs.

Schedule & Availability

• Part-Time Workload: Expect roughly 15–20 hours per week, with flexibility to manage ad setups and creative editing throughout the week.
• U.S. Overlap: Flexibility to coordinate tasks and respond during hours overlapping with U.S. business time (typically afternoon/evening EET/CET).
• Mandatory Syncs: Regular video check-ins with the team to sync on strategy, review creative performance, and take feedback from the client.

Requirements

 - Video & Technical Skills

• Hands-on Video Editing: Experience with video editing software/apps to slice video, format aspect ratios, and generate accurate captions/subtitles.
• Proven Meta Ads Expertise: Minimum 2+ years of hands-on experience managing direct-response ad budgets on Meta Ads Manager (D2C, health-tech, or consumer products).
• Tracking & Analytics: Solid understanding of Meta Pixel, Conversions API (CAPI), and basic funnel attribution.

 - Key Personal Traits (Soft Skills)

• Client-Centric & Attentive Listener: Ability to truly listen to client feedback, understand their brand vision, and align creatives accordingly without unnecessary pushback.

About the Project: We are building a massive, proprietary Ticketing & Event Management Ecosystem for the US market. This is NOT a standard booking site. We are engineering a custom, high-load platform from scratch. The ecosystem includes:

• On-Site Operations: Gate Scanning functionality and Ticket Printer control. We develop the scanning logic and integrate it with physical hardware for printing.

• Mobile Ecosystem: A feature-rich mobile application for organizers and attendees.

   

We don't use "out-of-the-box" solutions. We build our own logic to handle heavy complexity. If you prefer solving technical puzzles rather than integrating standard plugins, this is your place.

⚠️ THE CULTURE (Read this first): We are a US-based startup in an aggressive growth phase. We are looking for a Founding Engineer mindset.

• Intensity: We work with the US market. Late evening calls (European time) are standard to sync with the founders.
• Ownership: You don't just "close tickets." You own the feature from the database architecture to the UI. If the Gate System goes down on a Saturday night during a festival, you are the one helping to fix it.
• No "Code Monkeys": We discuss business goals. You need to understand why we are building a feature. If a requirement doesn't make sense technically, we expect you to push back and propose a better solution.

Tech Stack: React, Remix, Tailwind UI, Node.js, NestJS, TypeScript, PostgreSQL (TypeORM), GCP infrastructure.

Requirements:

• 5+ years of engineering experience, with deep expertise in the Node.js/React ecosystem.
• Modern Stack Mastery: You are proficient with NestJS on the backend and React/Remix + Tailwind UI on the frontend.
• Architectural Grit: Experience building custom complex systems (booking engines, CRM, logistics). You know how to design database schemas (PostgreSQL/TypeORM) that won't break under load.
• Integrations: Experience with payment processors (Stripe, etc.) and—crucially—an interest in working with hardware integrations (printers, scanners, IoT).
• US Startup Availability: You are comfortable working late hours and staying responsive during critical festival launches.
• Mobile Awareness: Knowledge of mobile development (React Native) is a plus.
• English: Upper-Intermediate or higher. You must be able to explain complex technical trade-offs to the founders.

Responsibilities:

• Engineer the Core: Design and develop the backend and frontend for the Ticketing Platform.
• Solve Hard Problems: Implement logic for Reserved Seating, interactive maps, and complex order flows.
• Hardware & Gate Logic: Write code that interacts with the physical world (scanning tickets, printing).
• Performance: Optimize the app to handle traffic spikes during ticket sales drops.
• Quality & DevOps: Write testable code, manage CI/CD pipelines, and deploy to GCP. You break it, you fix it.

We Offer:

• High Reward for High Performance: Competitive salary + Advanced Bonus System (We reward those who build the business with us).
• Real Engineering Challenge: No CMS wrappers. Pure custom development on an actual stack.
• Direct Impact: Your code runs the show at real festivals in the US.
