Knostic: Mid BE/FullStack Engineer

Middle BE-oriented FullStack Engineer

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:
Our client is building a platform designed to intercept and govern high-velocity AI traffic in real time. It inspects user prompts, AI responses, coding-agent actions, and enterprise search outputs across HTTP streams, IDE plugins, LLM APIs, and internal microservices—applying need-to-know access filters, policy transformations, and audit controls.

The system operates within sub-second decision loops, performs live data-stream classification, and enforces role- and context-based knowledge isolation, all while supporting deployment at global enterprise scale. Standard access-control models don’t hold in the AI era, which makes this engineering challenge both technically demanding and mission-critical: the team is building the control plane that keeps AI systems operating within strict business and security boundaries..

About the Role:
We are seeking a Middle Full-Stack Engineer (Backend-oriented) to join a remote, product-focused team building a real-time AI-governance platform. In this role, you will contribute to backend development using Node.js—implementing services, APIs, and platform features—while supporting front-end tasks in React as needed.

You will work closely with senior engineers, participate in design discussions, and take ownership of feature implementation end-to-end. This role is ideal for someone looking to deepen backend expertise while contributing across the full stack in a fast-moving, highly technical environment

Key Responsibilities: 

• Implement, maintain, and test backend services and APIs (Node.js/TypeScript) for a real-time AI-governance platform
• Contribute to front-end functionality (React) when required for feature completion
• Write clean, maintainable, and well-tested code aligned with best engineering practices
• Participate in code reviews and contribute to improving team standards
• Implement features end-to-end—from requirements through development, testing, and deployment
• Contribute to tooling, containerized environments, and CI/CD-related tasks
• Collaborate with product, engineering, and AI/security team members to deliver high-quality features
• Support debugging, optimization, and reliability improvements of existing systems

Required Competence and Skills:

• 3–6 years of professional experience in software development
• 2–4 years of hands-on experience with Node.js and JavaScript/TypeScript
• Working knowledge of React and modern front-end patterns
• Experience with relational databases (PostgreSQL or equivalent)
• Familiarity with cloud-native development practices and containerized environments
• Understanding of service-oriented architecture, APIs, and deployment workflows
• Good communication skills and ability to collaborate in a distributed team
• Ability to self-organize, learn quickly, and adapt to a dynamic startup-like environment

• Excellent English communication skills, both verbal and written

Nice to have:

• Experience building CI/CD pipelines (GitHub Actions or similar)

• Experience with Python and/or Go

• Production experience with TypeScript-based Node.js services
• Exposure to LLM/AI-driven applications (LLM APIs, vector DBs, orchestration tools)
• Experience integrating ML/AI models into production systems
• Background in B2B or security-oriented products
• BSc in Computer Science or related field
