Senior Full Stack Engineer (Node.js/React).

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 customer is building the first line of defense against the next generation of cyber threats: Autonomous AI Agents. Our mission in the face of complex unseen threats is turning what’s invisible into something we can see and act on.

As AI agents gain more autonomy inside enterprises, traditional security tools fail to explain what’s actually happening. This product changes that. It visualizes AI-agent behavior in real time, surfaces misconfigurations and vulnerabilities, and helps security teams intercept malicious or unintended LLM actions before damage occurs.

About the Role:
This is a rare early-stage Full Stack Engineer role for engineers who want to build something that actually matters. You’ll join at day zero, when architecture, UX, and product decisions are still open. This is not a “tickets and Jira” role. You’ll help decide what gets built and how, not just implement predefined tasks.

If you’re an engineer who wants your work to shape the product – not just support it, who craves ownership, thrives in startup environments, and obsesses over how users feel inside complex systems, this role is perfect for you.

Key Responsibilities: 

• Build beautiful, high-quality React interfaces that make complex AI-agent behavior easy to understand
• Design and implement Node.js / TypeScript services that handle real-time telemetry and data flows
• Create interactive agent maps and attack-path visualizations
• Own features end-to-end: from idea and architecture to production deployment
• Work directly with Product and leadership to shape the roadmap and UX
• Help define engineering standards, architecture choices, and product foundations

Required Competence and Skills:

• 4+ years of experience with Node.js and React
• Strong TypeScript across frontend and backend
• Excellent UI/UX instincts and attention to detail
• Experience with PostgreSQL and real-time systems (WebSockets, TanStack Query, or similar)
• Ability to work independently in a remote-first environment
• Strong communication skills and clear motivation for joining an early-stage startup

Nice to have: 

• Experience building SaaS dashboards or cybersecurity products
• Familiarity with AI-agent ecosystems (LangChain, CrewAI)
• Experience with Vercel
• A portfolio or GitHub that shows clean UI and thoughtful design
