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

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
