Senior Full-Stack Node.js Developer

🌍 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:

We are building an AI-first platform that fuses multiple maritime data sources into a unified operational picture. The system builds a digital twin of global maritime activity, applies behavioral analytics and predictive AI models to surface smuggling, illegal fishing, container risk, and other compliance or security threats, and presents mission-grade intelligence to both commercial and government stakeholders. 

🌟 About the Role:

We are looking for a Senior Full Stack Developer to own end-to-end features across frontend and backend services within a microservices ecosystem. This is a true full-stack role, with a relatively balanced split between backend (Node.js) and frontend (React.js) responsibilities.

You will collaborate closely with data science, DevOps, full-stack, and product teams to turn prototypes into scalable, production-ready services. 

📈 Key Responsibilities:

• Design, implement, and maintain microservices in JavaScript/TypeScript, ensuring high performance, reliability, and scalability.
• Develop and optimize frontend interfaces using React and GraphQL.
• Work with modern databases (MongoDB, DocumentDB, SingleStore) and messaging systems (Kafka, AWS SNS/SQS).
• Proactively audit and refactor existing services, leveraging AI agent workflows, MCP configurations, and structured documentation to improve architecture and consistency.
• Use AI-assisted development tools (e.g., Claude Code or similar) daily to boost productivity, code quality, and development velocity.
• Participate in architectural discussions and contribute to long-term technical roadmap decisions.
• Collaborate with data science and research engineers to integrate AI models and geospatial analysis pipelines into production services.
• Define and promote internal coding standards, reusable design patterns, and shared libraries across teams.
• Communicate effectively with product owners, support teams, and cross-functional stakeholders to align on requirements and technical trade-offs.

💻 Required Competence and Skills:

• 5+ years of professional experience in JavaScript/TypeScript, covering both frontend and backend development.
• At least 6 months of hands-on experience building features with AI agent coding tools (Claude Code, Codex, Cursor, etc.), including MCP, custom .md files, and subagent workflows.
• Strong production experience with Node.js and modern frontend frameworks (React.js). 
• Proven track record in a microservices architecture and service-to-service communication patterns
• Expertise in SQL and NoSQL databases (MongoDB, Amazon DocumentDB, SingleStore, etc).
• Experience working in cloud environments (preferably AWS).
• Familiarity with GraphQL API design and implementation.
• Advanced English communication skills, both verbal and written, with the ability to engage non-engineers

➕ Nice to Have:

• Experience with Kafka and SNS / SQS.
• Experience with geospatial analysis, GIS concepts, or integration of satellite data streams
• Background in complex domains (e.g., defense, sanctions, compliance, logistics).
• Prior experience with Kubernetes, Spark, Java-based backend components and building reusable internal platforms.
