Senior Fullstack Engineer

Senior Fullstack Developer (TypeScript / Node.js / React)

📍 Warsaw, Poland (Hybrid)

📄 CVs in English only, please!

We’re on the lookout for a Senior Fullstack Developer who’s passionate about building modern, scalable applications in a cloud-native environment. While our current focus leans slightly more toward backend development, we’re also open to experienced frontend developers or true 50/50 fullstack engineers. If you’re someone who thrives on challenge, ownership, and collaboration - we’d love to hear from you!

This is an opportunity to work in a collaborative, fast-moving setup where your voice matters and your code shapes the future of next-generation digital products. You’ll join a high-performing and growing engineering team working on greenfield products that serve thousands of users globally.

💼 What You’ll Do

• Design and implement end-to-end solutions using TypeScript, Node.js, and React.
• Contribute to greenfield projects — from architecture to deployment.
• Collaborate closely with product managers, designers, and engineers.
• Participate in architecture discussions, code reviews, and continuous improvements.
• Write clean, testable, and scalable code using best practices (unit/integration/E2E).
• Help shape a positive, curiosity-driven engineering culture.

🛠 Tech Stack

• Languages: TypeScript, JavaScript
• Frameworks & Libraries: Node.js, React, Next.js, NestJS
• Databases: PostgreSQL, SQL (NoSQL is a nice bonus)
• DevOps & Cloud: Docker, CI/CD (GitHub Actions, GitLab CI), Kubernetes (optional), GCP
• Testing: Cypress, Jest, or similar
• Architecture: Microservices, REST APIs, GraphQL

What We’re Looking For

• 7+ years of professional experience in fullstack development (with a backend emphasis preferred).
• Strong skills in TypeScript, Node.js, React, and relational databases like PostgreSQL.
• Experience with cloud-native architectures and CI/CD pipelines.
• Proven ability to work both independently and within agile teams.
• Confidence in building scalable systems from the ground up.
• Clear and structured communicator with strong problem-solving skills.
• A proactive mindset — you thrive in dynamic, ownership-driven environments.
• Fluent English communication skills (C1 level or higher).

Nice to Have

• Experience working with Google Cloud Platform (GCP) …but if you’ve worked in other cloud environments that’s a huge benefit for us too! 
• Familiarity with Docker and Kubernetes.
• Exposure to or interest in AI APIs like OpenAI or LangChain.

Who You Are

You’re someone who is:

• Open-minded, curious, and solution-oriented.
• Comfortable tackling challenges and learning new things.
• Open to stepping outside your comfort zone to push boundaries.
• Whether you're more backend, frontend, or a true full-stack — your mindset and skills are what matter most.

What We Offer

• A modern Scandinavian work culture focused on transparency, collaboration, and innovation.
• International projects with well-known Nordic clients.
• 20 days of paid vacation.
• Private healthcare and Multisport membership.
• Regular hackathons and a personal development budget.
• A supportive team that genuinely values your input.
• …Perhaps some business trips to Sweden? - who knows 😉
