Senior Full-Stack Engineer (Backend-Oriented, Node.js)

Build the real-time AI governance control plane trusted by global enterprises

Who We Are

Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies across a wide range of industries.

About the Product

You’ll work on a cloud-native AI governance platform designed to intercept, classify, and control high-velocity AI interactions in real time — without revealing the client’s identity.

The platform processes user prompts, model responses, coding-agent activity, and enterprise search operations across HTTP streams, IDE extensions, LLM APIs, and internal microservices. It applies need-to-know access filters, transformations, and audit controls within milliseconds, ensuring sensitive information never crosses boundaries it shouldn’t.

As enterprises adopt generative AI at scale, traditional access-control models break down. This platform introduces a new security layer purpose-built for AI systems, enabling organizations to innovate quickly while maintaining strict governance over their data and models. You’ll join a core engineering team building a system with real industry impact — one shaping how AI responsibly integrates into the modern enterprise.

About the Role

We’re looking for a Senior Full-Stack Engineer (Backend-focused) to join a small, high-caliber engineering team developing the core components of this real-time governance platform.

Your primary focus will be backend development using Node.js/TypeScript — implementing scalable services, APIs, and platform features. When needed, you will support frontend development in React to deliver features end-to-end. You will collaborate closely with senior engineers, contribute to technical discussions, and take ownership of delivering reliable, high-quality features in a fast-moving, deeply technical environment. You’ll be working in a multi-service production environment where components depend on each other, taking part in architecture discussions, shaping how services integrate, and supporting the platform as it scales — with a focus on reliability and real production behavior.

Why This Role Stands Out

✔ High-impact product defining how enterprises safely adopt AI
✔ Real engineering challenges — real-time processing, distributed flows, policy logic
✔ Modern tech stack: Node.js, TypeScript, React, PostgreSQL, Docker, cloud-native practices

 ✔ Work on production systems with multiple services and real traffic

 ✔ Take ownership of features end-to-end and see how they perform in production
✔ Work alongside experienced engineers and grow your backend expertise
✔ Strong ownership opportunities within a compact, highly collaborative team
✔ Remote-first environment with strong support and flexibility

What You Bring

• 6+ years of professional software development experience
• 4+ years of hands-on experience with Node.js and TypeScript
• Working knowledge of React and modern frontend development
• Understanding of backend architecture, APIs, and service-oriented design
• Experience with relational databases (PostgreSQL or similar)
• Experience with containerized and cloud-native environments
• System understanding and experience participating in architecture discussions
• Strong communication skills and ability to collaborate in a distributed team
• Ability to operate in a dynamic, fast-paced product environment
• Excellent English communication skills (written and spoken)

Nice to Have

• Experience with CI/CD pipelines (GitHub Actions or similar)
• Experience with Python and/or Go
• Production experience with TypeScript-based backend systems
• Exposure to LLM/AI applications (LLM APIs, vector DBs, orchestration frameworks)
• Experience integrating ML/AI models into production
• Background in B2B or security-focused products
• BSc in Computer Science or related field
  
   

Why Us

• 20 days of annual vacation + official national holidays
• Full accounting and legal support across all operating countries
• Fully remote setup with a powerful workstation and coworking options
