GraphQL API development and schema design at scale
LLM/AI integration patterns (structured outputs, LLM workflow orchestration)
Security-conscious development and compliance frameworks (SOC 2, NIST 800-171/800-53)

Open-source contributions or active technical community involvement
Why Join Collaboration AI?
Work that matters. We build AI-powered solutions for defense, public sector, and regulated industries — SOC 2 and NIST compliance, FedRAMP readiness, and customers whose missions demand the most trustworthy software
AI-native by default. We build with AI, not just for AI. Agentic coding tools (Claude Code/Codex/etc.), agent SDKs and harnesses, MCP servers, and Agent Skills standards are how we work daily. You'll push the boundaries of what AI tooling can do across the full stack
Real ownership. High-autonomy culture on a small, senior team. You'll own outcomes end-to-end — and your work will be seen, used, and valued
Modern stack, no legacy drag. Cloud-native Kubernetes infrastructure, Kotlin and Next.js, continuous delivery — built for growth, not maintenance mode
