Full Stack Node/Typescript Engineer

Culmen International is seeking a Full Stack Engineer to join a small, high-impact team focused on building data-intensive products at the intersection of modern web infrastructure and AI. The role involves working across the full lifecycle of development, from API design to frontend integration, with a strong emphasis on data fluency and collaboration within the team.

Responsibilities:

• Dive deep into our existing codebase to build a thorough understanding of our architecture, data models, and service dependencies — becoming a reliable backup and steward of core systems
• Write clean, well-documented TypeScript and Node.js code across backend services, APIs, and frontend features, with a consistent eye toward maintainability and performance
• Manage your work through Jira — picking up tickets, contributing to sprint planning, and keeping tasks and statuses accurate so the team always has clear visibility into progress
• Collaborate via GitHub using pull requests, code reviews, and branching strategies that keep our codebase healthy and deployments predictable
• Maintain and expand technical documentation in Confluence, ensuring that institutional knowledge is captured, up to date, and accessible to the whole team
• Participate in regular code reviews — both giving and receiving feedback thoughtfully to raise the quality bar across the board
• Help triage, debug, and resolve production issues, taking ownership of problems through to resolution rather than passing them along
• Contribute to the design and implementation of new features end-to-end, from data modeling and API design to integration and testing
• Proactively flag technical debt, inconsistencies, or risks you encounter and work collaboratively to address them over time
• Engage in team ceremonies — standups, sprint reviews, retrospectives — and bring a constructive, communicative presence to everything you do

Requirements:

• Experience with Node.js and TypeScript
• Strong fluency in SQL and data modeling
• Comfort thinking through schema design, query optimization, and data flow
• Experience with Google Cloud Platform (GCP) services like BigQuery, Cloud Run, Vertex AI, or Cloud Storage
• Familiarity with Claude Code or similar AI-assisted development tools
• Experience working with or building agentic AI systems
• Prior experience supporting federal government contracts or programs
• Exposure to geospatial data concepts, tools, or platforms
• Experience with data pipeline development
• Familiarity with Python as a secondary language
• Comfort working in a startup or small team environment
• Genuine curiosity about agentic AI implementations
• Interest in mobile data collection platforms, intelligence tooling, or data-as-a-service products
