Senior Full-Stack Software Engineer

Position OverviewKollabio 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 OwnDesign and implement modular, scalable backend services using NestJS and TypeScriptArchitect and build responsive front-end applications using Next.js, React, or VueIntegrate AI/LLM APIs into platform features, including prompt engineering and orchestration patternsBuild and maintain CI/CD pipelines, infrastructure-as-code, and cloud-native deployments on AWSTranslate product requirements into well-structured technical designs and decompose features into clean, independently deployable incrementsEnforce code quality through disciplined pull requests, peer reviews, and meaningful automated testsEnsure APIs are clearly documented and aligned with OpenAPI standardsContribute to architectural decisions, threat modeling, and DevSecOps practices within defined platform principlesParticipate actively in technical grooming, risk identification, and sprint planningRequirementsCore Engineering8+ years of full-stack development experience in production environmentsDeep proficiency in TypeScript across the entire stackStrong backend architecture experience using NestJS or comparable Node.js frameworks (Express, Fastify)Advanced experience with React, Next.js, or Vue for front-end developmentExperience designing, building, and scaling RESTful APIsStrong understanding of application state management, front-end performance, and responsive designAI-Assisted DevelopmentActive, 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 applicationsUnderstanding of prompt engineering, token management, and AI-augmented system design patternsInfrastructure & DevSecOpsExperience 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 & CollaborationExperience working in structured Agile environments with clear Definition of Done standardsComfort operating in small, high-accountability teams with minimal oversightStrong written and verbal communication of technical decisions and tradeoffsPreferred ExperienceRedis caching strategies and message queue architecturesExperience 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 postsActive security clearance (Secret or above)What Success Looks LikeClean architectural decisions with minimal reworkFeatures delivered production-ready without "temporary" shortcutsMeasurable productivity and quality gains from effective use of AI-assisted development toolsStrong PR discipline and thoughtful, constructive code reviewsInfrastructure that is reproducible, documented, and secure by defaultClear communication of tradeoffs, risks, and technical debt implicationsContributions that improve system robustness, observability, and developer experience over timeWho Will Thrive in This RoleEngineers who prefer ownership over task listsDevelopers who think in systems and platforms, not just tickets and featuresIndividuals who view AI-assisted development as a force multiplier, not a crutchProfessionals who care about maintainability, security, and operational disciplinePeople who are comfortable building in evolving, fast-paced environments with high expectationsAbout KollabioKollabio is a design and engineering firm that creates human-driven, AI-empowered solutions for federal agencies, GovCon primes, and commercial enterprises.
