🚀 Senior Software Engineer — Remote, Eastern Europe
TubeScience | Full-Time | Remote-First
FULLY REMOTE. MUST BE BASED IN EASTERN EUROPE
About TubeScience
TubeScience is one of the fastest-growing performance video companies in the world. We use data, AI, and creative systems to produce video advertising at a scale and speed that no one else has figured out. Our engineering team builds the infrastructure that makes that possible — from AI agent pipelines to the ad operations tooling that drives hundreds of millions in client spend.
We are profitable, growing fast, and building in a space where the technical problems are genuinely hard. This is not a maintenance role. You will be architecting and shipping systems that directly move business outcomes.
The Role
We are hiring a Senior Software Engineer to join our core platform team. You will work across the full stack — frontend tooling for complex ad workflows, cloud infrastructure, and the backend systems that tie our AI integrations together. You will be one of a small number of engineers who sets the technical direction, not just executes it.
This role is fully remote. You will work closely with engineers and product leads in the US, with meaningful overlap during afternoon hours in your timezone (CET/EET).
What You Will Build
What We Need From You
If you have worked with any of the following, say so: React/Next.js, FastAPI/Django/Flask, Docker/Kubernetes, PostgreSQL/MongoDB/Redis, Temporal/Airflow/Dagster, Kafka/RabbitMQ, AuthN/AuthZ patterns.
Nice to have: experience shipping agent systems (MCPs, sandboxing, AI agent infrastructure) and FinOps at scale.
Why Join Us
We're experiencing exceptional growth in a contracting market. We combine startup agility with established financial stability. You'll work on exciting challenges with a brilliant team of like-minded professionals who value both technical excellence and creative problem-solving. You'll have immediate impact on critical systems and clear paths for professional advancement.
This isn't just another job - it's your chance to build something meaningful with people who are as passionate and talented as you are.
As one of the fastest growing startups in Los Angeles, we're revolutionizing the way in which companies approach successful video advertising. Our team of award-winning Producers, Editors, Directors, Engineers, and Performance Marketing Managers are building a global studio where we can conceptualize, shoot, and produce hundreds of videos per day. Unlike traditional advertising agencies that pitch creative concepts for companies, hope they will perform, and outsource filming, we design videos that are guaranteed to convert. We use data to guide our creative process and leverage testing and analysis to make adjustments to react to users in real-time.
What's atypical about the company:
We're fast and data-driven: our teams develop concepts in the morning, shoot/edit in the afternoon, launch in the evening, and iterate the next day based on real-world performance.
We’re a behavioral R&D lab at the core: We put 2,000+ video experiments per week, watched by tens of millions of people per day, that give us deep insights into how people make decisions. Over the past couple years, we’ve built an enormous library of IP around human behavior and visual communication.
We work on a pure pay for performance basis. Zero production fees for video. Clients only pay us if our videos outperform anything they’re running internally.
