We’re building a next-generation cybersecurity platform from scratch - and we need a Senior Full Stack Developer who’s ready to own the product end to end. If you love shipping fast, writing clean code, and working at the intersection of security and great UX, this is your role.

What You’ll Do:

• Shape the product from day one: Architect and ship a web-based cybersecurity platform built for speed, security, and scale.
• Drive features end to end: Take ownership across the entire stack - from early design through deployment and iteration.
• Work closely with the team: Partner with product, design, and fellow engineers to solve hard problems and move fast.

• Keep the bar high: Write clean, well-tested code, build secure APIs, and champion code reviews across the team.

   

Must-Have Requirements:

• At least 5 years of professional Full Stack development - this is a senior role and we need someone who can hit the ground running and lead from day one.
• You actively use AI coding tools (GitHub Copilot, Cursor, or similar). They’re part of our daily workflow.
• Deep hands-on experience with React, TypeScript, Node.js, and Python. This is what we build with every day.
• You know your way around PostgreSQL, MongoDB, and can work comfortably across both SQL and NoSQL databases.
• Real-world experience deploying and running services on AWS with Docker and Kubernetes.
• You’re self-driven, naturally curious, and energized by shipping things that actually matter.

🚀 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.

The platform analyzes user prompts, AI responses, coding-agent activity, and enterprise search outputs. 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. 

This product introduces a new security layer designed specifically for AI systems, enabling organisations to innovate quickly while maintaining strict governance over their data and models.

🎯 About the Role:
We are looking for a Principal Full-Stack Engineer (Backend-focused) to join a small, high-caliber team developing the core components of the system.

- Your primary focus will be backend engineering with Node.js/TypeScript - 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 teams. 

🔥 Why This Role Stands Out:

• Mission-critical product and deep engineering challenges 
• Modern stack: Node.js, TypeScript, React, PostgreSQL, Docker, cloud-native tooling
• Focus on architectural thinking: system structure, service-to-service communication, and production scalability
• Work on real multi-service production systems
• High degree of autonomy and technical ownership
• 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, including strong understanding of runtime behavior and performance optimization
• Strong knowledge of backend architecture, distributed systems, scalable service design, and service-to-service communication in multi-service production environments
• Proven experience building SaaS systems with relational databases (PostgreSQL or similar) in containerized/cloud-native environments
• Practical React experience sufficient for full-stack delivery
• 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

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.
