At Variant Group, we are at the forefront of reimagining day-to-day challenges.
Our B2C SaaS products transform complex tasks — from creating standout resumes to generating contracts and converting PDFs — into simple, engaging user experiences.
Products
pdf.net is one of the fastest-growing products in our portfolio. Thanks to bold product breakthroughs, it already serves hundreds of thousands of users every month, and is on track for even greater growth. To support this scale, we are hiring a hands-on Technical Lead (Fullstack/Infrastructure) who will become the center of expertise for backend systems, infrastructure, and AI integrations.
What You’ll Do
- Own backend architecture for pdf.net: Node.js services, APIs, scaling, and infrastructure.
- Oversee and guide the integration of AI/LLM components (Python-based) into production systems.
- Provide technical leadership for a growing team of 6–7 engineers (full-stack JS + Python AI), scaling further.
- Establish best practices for code quality, CI/CD, testing, observability, and reliability.
- Improve existing CI/CD pipelines (GitHub Actions) and build new ones.
- Collaborate with the CTO (frontend expertise) to ensure cohesion across the stack.
- Be hands-on: design, code, review, debug, and set technical standards.
- Drive architectural decisions for backend systems powering hundreds of thousands of users.
- Mentor engineers and build a strong backend culture.
