About The Position

Kollabio is building an AI-native platform designed to transform how organizations manage knowledge, workflows, and decision-making. We are seeking a Senior Full-Stack Software Engineer who operates with ownership and delivers systems-ready code at scale. You will own significant portions of the platform across the entire stack, translating product intent into clean system design and production-ready implementation. This is a systems-oriented engineering role for someone who builds with structure, clarity, and durability. You'll work in a focused, high-accountability environment where architectural thinking, disciplined execution, and long-term maintainability are non-negotiable. You're comfortable navigating ambiguity, making pragmatic tradeoffs, and delivering robust solutions with minimal oversight. AI-Native Engineering: We are an AI-forward engineering team. You will be expected to use AI-assisted development tools (Cursor, Windsurf, Claude Code, GitHub Copilot) as part of your daily workflow—not as an experiment, but as a core productivity and quality multiplier. You'll also design and integrate AI/LLM capabilities directly into our products, translating AI innovations into measurable user value. Comfort with AI-augmented development is a baseline expectation for this role.

Requirements

• 8+ years of full-stack development experience in production environments
• Deep proficiency in TypeScript across the entire stack
• Strong backend architecture experience using NestJS or comparable Node.js frameworks (Express, Fastify)
• Advanced experience with React, Next.js, or Vue for front-end development
• Experience designing, building, and scaling RESTful APIs
• Strong understanding of application state management, front-end performance, and responsive design
• Active, daily use of AI-powered development tools (Cursor, Windsurf, Claude Code, GitHub Copilot, or similar)
• Experience integrating AI/LLM APIs (OpenAI, Anthropic, etc.) into production applications
• Understanding of prompt engineering, token management, and AI-augmented system design patterns
• Experience with AWS services (EC2, ECS/EKS, Lambda, S3, RDS, CloudFront, IAM)
• Hands-on experience with CI/CD pipelines (GitHub Actions, GitLab CI, or similar)
• Working knowledge of containerization (Docker) and orchestration (Kubernetes or ECS)
• Familiarity with infrastructure-as-code (Terraform, CDK, or CloudFormation)
• Experience working in structured Agile environments with clear Definition of Done standards
• Comfort operating in small, high-accountability teams with minimal oversight
• Strong written and verbal communication of technical decisions and tradeoffs

Nice To Haves

• Redis caching strategies and message queue architectures
• Experience building SaaS or enterprise platform products (not just client projects)
• Familiarity with federal compliance requirements (FedRAMp, NIST, ATO processes)
• Experience with monorepo tooling (Nx, Turborepo)
• Contributions to open-source projects or technical blog posts
• Active security clearance (Secret or above)

Responsibilities

• Design and implement modular, scalable backend services using NestJS and TypeScript
• Architect and build responsive front-end applications using Next.js, React, or Vue
• Integrate AI/LLM APIs into platform features, including prompt engineering and orchestration patterns
• Build and maintain CI/CD pipelines, infrastructure-as-code, and cloud-native deployments on AWS
• Translate product requirements into well-structured technical designs and decompose features into clean, independently deployable increments
• Enforce code quality through disciplined pull requests, peer reviews, and meaningful automated tests
• Ensure APIs are clearly documented and aligned with OpenAPI standards
• Contribute to architectural decisions, threat modeling, and DevSecOps practices within defined platform principles
• Participate actively in technical grooming, risk identification, and sprint planning
