Senior Full-Stack Engineer (AI-First)

The Cybermaniacs is a startup focused on building human risk and AI workforce resilience intelligence software. They are seeking a hands-on Senior Full-Stack Engineer to contribute to their core platform, focusing on deep back end work and AI tooling integration.

Responsibilities:

• Maintain, improve, and evolve the AI-assisted workflows across the full PDLC and SDLC
• Write code every day and take pride in the quality of the code shipped
• Hold the bar on reliability and testing across everything touched, including AI-generated code
• Work directly with the founding team and clients to shape the product
• Focus on deep back end work, including services architecture, knowledge graph development, and agent infrastructure

Requirements:

• 10+ years hands-on full-stack engineering — you still write the code, every day
• Deep back end expertise: distributed systems, event-driven architecture, microservices, async patterns
• A proven track record of delivery — you ship things that work, on time, in production
• Serious about testing and reliability — unit, integration, end-to-end, and the discipline to apply this to AI-generated code too
• Genuine AI-first engineering mindset — you've integrated LLMs and agents into real products, not just prototypes
• Interest in graph data modeling and knowledge architecture
• Comfortable being the most experienced person in the room without needing to manage the room
• Self-directed, low ego, high output, good sense of humor
• Neo4j or other knowledge graph experience
• GCP experience (Cloud Functions, Storage, CDN)
• Auth0 / SCIM / SAML enterprise auth patterns
• Reliability engineering or platform engineering background
• Early-stage startup or founding engineer experience
