About the Role

As a Fullstack Engineer focused on AI Integration at Oneleet, you'll be responsible for bringing our AI capabilities to life within our cybersecurity platform. You'll work across our entire stack to integrate AI endpoints, prepare contextual data, and create intuitive interfaces that make complex AI-powered insights accessible to our users.

This is a hands-on engineering role where you'll own the complete integration flow — from gathering the right security context from our platform, calling our AI services effectively, to presenting results in ways that drive real value for security teams. You'll work primarily in Go, Python, and JavaScript to ensure our AI features are fast, reliable, and genuinely useful.

Key Responsibilities

• Integrate AI service endpoints into our platform, handling authentication, error states, and response processing.
• Design and implement context gathering systems that pull relevant security data from across our platform to feed into AI services.
• Build intuitive UI components in JavaScript/React that present AI-generated insights, recommendations, and automations to users.
• Map AI service responses to actionable UI elements, ensuring complex outputs are presented clearly and drive user action.
• Implement robust error handling and fallback behaviors when AI services are unavailable or return unexpected results.
• Create feedback loops that capture user interactions with AI features to drive continuous improvement.
• Work directly with customers to understand how they use AI features and rapidly implement UX improvements.
• Optimize API calls to AI services for performance, implementing caching where appropriate while maintaining data freshness.
• Build monitoring and analytics to track AI feature usage, success rates, and user engagement.
• Collaborate with the AI team to communicate platform needs and user feedback that could improve the underlying services.
• Develop reusable patterns and components for AI integration that can be leveraged across different features.
• Ensure AI features integrate smoothly with existing platform workflows and don't disrupt current user patterns.

Qualifications

• 5+ years of fullstack software development experience with expertise in Go and JavaScript.
• Strong experience building production APIs (REST and/or gRPC) and integrating with third-party services.
• Proven track record of building responsive, intuitive user interfaces with modern JavaScript frameworks (React preferred).
• Experience with data transformation and mapping between different system formats.
• Strong understanding of asynchronous programming patterns and API optimization techniques.
• Experience gathering requirements from users and translating feedback into technical improvements.
• Solid debugging skills across the full stack — from backend services to frontend UI.
• Experience with production monitoring, logging, and observability tools.
• Strong communication skills and comfort working directly with customers.
• Ability to balance technical excellence with shipping features that provide immediate value.

Bonus Experience

• Previous experience integrating AI/ML services into production applications.
