    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 β€” 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 β€” 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 development using Node.js/TypeScript β€” 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 β€” 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
    • 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)
    • 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.

    - Modern C++ and low-level optimization;
    - PyTorch custom operators and backend integrations;
    - Mixed/low-precision computing;
    - English level C1/C2.

    Responsibilities:
    - Design and development of environments and tasks;
    - Working with a given model and complexity distribution;
    - Approximately 1 task per ~10 hours;
    - Quickly make edits based on client feedback.

    It will be a plus:
    - Experience with RL environments or evaluation frameworks;
    - Work in regulated or high-stakes domains;
    - Experience with MLOps, CI/CD, and monitoring;
    - Systems background (C++ / Rust / Java / Scala);
    - Understanding of RL, bandits, and agent systems.

    Working conditions:
    - Remote, contract model;
    - Project duration: 1 year or more;
    - At least 4 hours of PST (UTC-8, the winter time zone used on the West Coast of the US, Canada, and Mexico);
    - Quick onboarding, start from day one.
