* 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.

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.

Your primary focus will be
** backend engineering with Node.js/Type Script** — 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, Dev Ops, 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, Type Script, React, Postgre

SQL, 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 Type Script
* Strong knowledge of backend architecture, distributed systems, and scalable service design
* Proven experience working with SaaS-based systems
* Experience with relational databases (Postgre

SQL or similar)
* Experience with containerized/cloud-native environments
* Practical React experience sufficient for full-stack delivery
* Deep understanding of JavaScript/Type Script 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 (Git Hub Actions or similar)
* Experience with Python and/or Go
* Production experience with large-scale Type Script-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
