Senior Full Stack Developer (React+Node.js) with AI agent coding tools experience

🚀 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. 

Operating at global scale, the platform processes millions of events and terabytes of geospatial data daily, relies on cloud infrastructure and microservices, and integrates with upstream research prototypes from data science teams. 

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 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.

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.
