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 in 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 analyzes user prompts, AI responses, coding-agent activity, and enterprise search outputs flowing across HTTP streams, IDE extensions, LLM APIs, and internal microservices. It applies need-to-know access filtering, policy transformations, and audit controls within sub-second decision windows, ensuring sensitive knowledge never crosses boundaries it shouldn’t. As enterprises adopt generative AI at scale, traditional access-control models break down. This product 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 will be joining a core engineering team that is building a platform with real industry impact — one shaping how AI responsibly integrates into the modern enterprise.

About the Role:

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

Your primary focus will be backend engineering with Node.js/TypeScript — building high-performance services, scalable APIs, distributed processing flows, and policy-evaluation pipelines. When needed, you’ll contribute to the React-based frontend to deliver features end-to-end. You will take ownership of major technical decisions, collaborate with engineering, product, DevOps, and AI/security

Why This Role Stands Out:

• Mission-critical product defining how enterprises safely adopt AI
• Deep engineering challenges — real-time pipelines, distributed flows, policy engines
• Modern stack: Node.js, TypeScript, React, PostgreSQL, Docker, cloud-native tooling
• High degree of autonomy and technical ownership
• Work closely with an elite product and AI/security team
• Fully remote, flexible environment with strong operational support

What You Bring:

• 10+ years of professional software development experience
• 5+ years of hands-on experience with Node.js and TypeScript
• Strong knowledge of backend architecture, distributed systems, and scalable service design
• Proven experience working with SaaS-based systems
• Experience with relational databases (PostgreSQL or similar)
• Experience with containerized/cloud-native environments
• Practical React experience sufficient for full-stack delivery
• Deep understanding of JavaScript/TypeScript runtime patterns and performance considerations
• Strong communication skills and comfort working asynchronously in a distributed team
• Ability to thrive in a fast-paced, high-ownership environment
• Excellent English (written and spoken)

Nice to Have:

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

Why Us?

We provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).

We provide full accounting and legal support in all countries we operate.

We utilize a fully remote work model with a powerful workstation and co-working space in case you need it.

We offer a highly competitive package with yearly performance and compensation reviews.
