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.

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 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

• 5 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)

• Familiarity with containerized and cloud-native environments

• 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

•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.

 

Join the development of nuclear programs at the International Atomic Energy Agency (IAEA). You’ll contribute to web solutions used within nuclear programs, working in an enterprise setup focused on stability, accuracy, and maintainable architecture.

What you’ll do

• Build and maintain web-based interfaces using Angular + TypeScript.
• Develop UI components with HTML and CSS3.
• Collaborate closely with the Backend engineer and contribute to full-stack delivery when needed.
