Senior Full-Stack Software Engineer

Kollabio•Brambleton, VA

About The Position

Kollabio is building an AI-native platform designed to transform how organizations manage knowledge, workflows, and decision-making. We are hiring a Senior Full-Stack Software Engineer to own significant portions of the platform across the entire stack. This is a systems-oriented engineering role for someone who builds with structure, clarity, and durability. You will take product intent and translate it into clean system design and production-ready implementation. You'll work in a focused, high-accountability environment where architectural thinking, disciplined execution, and long-term maintainability are non-negotiable. 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 multiplier. Comfort with AI-augmented development is a baseline expectation for this role.

Requirements

7+ 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
PostgreSQL experience; familiarity with Prisma ORM preferred
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
Ability to obtain Clearance
