Senior FullStack Engineer to $6700

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 Senior Full-Stack Engineer (Backend-oriented) to join a remote, product-driven team building a real-time AI-governance platform for enterprise environments. You will focus primarily on backend development using Node.js—designing scalable services, APIs, and core backend flows—while contributing to front-end tasks in React when needed to deliver complete features.

In this role, you’ll own development end-to-end, collaborate closely with engineering, product, and a small AI/security group, participate in architectural decisions, and help evolve a high-performance platform operating under strict real-time constraints.

Key Responsibilities:

• Design, build, and maintain backend services and infrastructure for a real-time AI-governance platform (Node.js/TypeScript)
• Develop scalable APIs, policy-evaluation flows, data-processing logic, and distributed components
• Contribute to front-end functionality (React/TypeScript) when required for full feature delivery
• Participate in architectural design, technical discussions, and code review processes
• Build and support deployment tooling and containerized services across multiple environments
• Write well-tested, maintainable code aligned with a high-frequency release cycle
• Collaborate with product, engineering, QA, DevOps, and AI/security team members to deliver high-quality features on schedule
• Take ownership of debugging, improving, and maintaining existing backend systems alongside new development

Required Competence and Skills:

• 7+ years of professional software development experience
• 5+ years of hands-on experience with Node.js and TypeScript
• Solid understanding of backend architecture, distributed systems, and scalable service design
• Experience with front-end technologies (React) sufficient for supporting full-stack delivery
• Strong knowledge of JavaScript/TypeScript runtime patterns and performance considerations
• Experience working with relational databases (PostgreSQL or equivalent)
• Experience with containerized development environments and cloud-native practices 
• Strong communication skills and the ability to work asynchronously in a distributed team
• Comfortable operating in a fast-paced environment with high ownership expectations
• 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
