About Framna

At Framna, we partner with ambitious brands to build digital products that make a real impact. We work across the full product journey from strategy and UX to engineering and long-term growth, combining strong technical expertise with a product mindset.

Our culture is built on trust, ownership, and collaboration. We value open communication, continuous learning, and teams that take responsibility for what they build.

About the role & project

We are developing a next-generation biometric authentication platform safeguarding millions of transactions, engineering high-end backend services capable of real-time analysis at scale. As a Senior Backend Engineer (Node.js, TypeScript), you will hold full architectural ownership of mission-critical systems and directly shape the product.

While we foster an AI-driven delivery mindset, we place immense value on low-level engineering depth-knowing that true system resilience, performance, and bulletproof security demand a thorough understanding of what happens under the hood.

We follow a hybrid work model, with regular in-office syncs to stay aligned as a team.

  • Strong proficiency in TypeScript

  • Solid experience with Node.js (NestJS)

  • Good understanding of secure backend design principles (e.g. authentication, authorization, data protection, API security)

  • Experience working with GCP or other cloud platforms

  • Strong knowledge of databases (SQL and NoSQL)

  • Solid understanding of HTTP, REST APIs, and web communication patterns

  • Experience with backend testing frameworks and testing strategies

  • Experience using AI tools effectively and responsibly in day-to-day development

  • Very good command of English and Polish

What you will find at Framna

  • Real ownership and influence on the products you build

  • A focus on business value over technical perfection

  • Continuous feedback and open communication

  • Regular 1:1s and a mentoring program to support your growth

  • Internal workshops and knowledge sharing across teams

  • Flexible working hours (you can start between 7:00–10:00)

  • Hybrid model with regular in-studio syncs (twice a month)

  • High-quality equipment, including MacBook and testing devices

  • Individual training budget

  • English classes in small groups

Plus the essentials:

  • Private medical care (Compensa) and MultiSport

If this sounds like your kind of environment, we would love to hear from you.
