# Senior Full-Stack Software Engineer > Kollabio · Brambleton, United States (Hybrid) · Full-time · Posted 2026-06-01 **Workplace:** hybrid ## Description ### Position Overview 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. ### What You Will Own - 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 ## Requirements ### Core Engineering - 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 ### AI-Assisted Development - 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 ### Infrastructure & DevSecOps - 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) ### Process & Collaboration - 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 ### Preferred Experience - 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) ### What Success Looks Like - Clean architectural decisions with minimal rework - Features delivered production-ready without “temporary” shortcuts - Measurable productivity and quality gains from effective use of AI-assisted development tools - Strong PR discipline and thoughtful, constructive code reviews - Infrastructure that is reproducible, documented, and secure by default - Clear communication of tradeoffs, risks, and technical debt implications - Contributions that improve system robustness, observability, and developer experience over time ### Who Will Thrive in This Role - Engineers who prefer ownership over task lists - Developers who think in systems and platforms, not just tickets and features - Individuals who view AI-assisted development as a force multiplier, not a crutch - Professionals who care about maintainability, security, and operational discipline - People who are comfortable building in evolving, fast-paced environments with high expectations ### About Kollabio Kollabio is a design and engineering firm that creates human-driven, AI-empowered solutions for federal agencies, GovCon primes, and commercial enterprises. We combine Experience Thinking — practical design thinking with the how-to included — with Agile delivery and continuous deployment to ship measurable value in multiple increments and with continuous feedback loops.
