Job description

What is Vetric?

Vetric is the intelligence behind the teams that stop crime online. Investigators, analysts and platform defenders use Vetric to see what bad actors do in the open, from fraud and impersonation to organized crime, terror networks and foreign influence, so they can act before harm spreads. Vetric doesn’t do that work itself but powers the people who do. The social and video intel runs inside customers’ own products, as a dependency their roadmaps are built on, which is why reliability and depth count for as much as coverage. Operating globally, Vetric serves industry leaders across more than 20 countries in cybersecurity, digital risk protection and public safety teams.

Why Vetric?

Vetric is profitable from day 1 (fully bootstrapped - means we didn’t raise any money), a fast-growing company building foundational technology - not chasing trends. Because this is infrastructure that matters, it requires engineering discipline, ownership, and long-term thinking. As part of our broader R&D expansion, we’re building Kraków into a key engineering hub that will own core systems and drive our next phase of innovation and growth.

Position Overview

We’re looking for a highly skilled Senior Software Engineer to help us build a brand-new product from the ground up. You’ll play a key role in designing and developing high-scale, event-driven backend systems, working closely with product and engineering teams in a fast-moving environment. This is a hands-on role for someone who thrives in ambiguity, learns quickly, and enjoys shaping architecture early on.

Responsibilities

• Develop and maintain backend services using Node.js and TypeScript.
• Design and implement high-performance APIs and event-driven architectures on AWS.
• Build scalable, reliable systems capable of handling intensive workloads.
• Lead feature development end-to-end - from design to production.
• Collaborate closely with product and cross-functional engineering teams.
• Mentor teammates and promote best practices in code quality, testing, and security.
• Continuously adapt as the product evolves and new challenges emerge.

Requirements

• 5+ years of hands-on experience with Node.js and TypeScript in production.
• Strong experience with AWS services (e.g., Lambda, ECS, S3, RDS).
• Deep understanding of system design, scalability, and event-driven architecture.
• Experience with modern testing frameworks (Vitest, Jest, Playwright).
• Strong problem-solving skills and ability to work independently.
• Excellent communication skills in English.
• Ability to thrive in a dynamic, fast-paced environment.

Nice to Have

• Background in distributed systems or event-driven platforms.
• Experience working with LLMs or modern AI tooling.
• Experience with SQL and NoSQL databases
• Experience with Docker, Kubernetes, and CI/CD best practices.

What We Offer

• Competitive compensation aligned with the Kraków tech market (UoP or B2B options).
• Hybrid work model in Kraków.
• Opportunity to shape a new product from day one.
• High ownership and real impact.
• Work in an international, English-speaking engineering environment.
• A stable, profitable company with long-term vision.

We hire people — not just skill checklists.
