    Mission of the Role

     

    To quickly and reliably create prototypes and MVPs (web apps, internal tools, AI agents workflows), using low-code/no-code and AI-assisted development, bringing them to deployment, monitoring, and clear support.

     

    Key Tasks

    • Quickly assemble prototypes and MVPs: UI, logic, integrations, data storage, authorization, basic analytics.
    • Make AI-assisted coding the standard: code generation, refactoring, tests, documentation, development acceleration.
    • Translate business needs into requirements: user flows, roles, edge cases, constraints, acceptance criteria.
    • Integrate external services: CRM, payments, email/SMS, messengers, webhooks, partner APIs.
    • Design a simple but correct MVP architecture: so it doesn't fall apart under the first load.
    • Set up deployment and environments: dev/stage/prod, secrets, domains, SSL, basic CI/CD.
    • Establish observability: logging, basic monitoring, alerts, error tracking.
    • Participate in task estimation: timelines, risks, trade-offs (fast vs. correct), release plan.

    What We Consider Success (KPI / Outcomes)

    • MVP in production in 2-6 weeks (depending on scale) with working key scenarios.
    • Reduction in development time due to AI tools (visible increase in speed and quality).
    • Minimum blocker bugs at launch, transparent logs, and reproducibility.
    • Clear artifacts: brief PRD/BRD-lite, technical description, deployment, and support instructions.

    Mandatory Requirements (must-have)

    • 2+ years in prototype/MVP development or a strong portfolio with real launches.
    • Ability to work in conditions of uncertainty: formulating requirements together with the business.
    • Understanding of business processes and business analysis skills: asking the right questions, documenting processes, identifying bottlenecks.
    • Confident work with APIs, webhooks, databases (SQL/NoSQL), auth (JWT/OAuth), queues, or their substitutes.
    • Understanding of deployment and operation: Docker (preferred), cloud deploy, environment variables, secrets, domains.
    • Experience using AI development tools as a daily practice.

    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 engineering with Node.js/TypeScript β€” 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 β€” 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.
