hirify.global inspires people to achieve great things together with the first AI-native Employee Experience Platform.

What you will do

• Lead the implementation of scalable backend services and AI-native applications.
• Act as the technical special forces across 2-3 high-priority teams, solving the most complex architectural puzzles.
• Partner with PMs and ML engineers to turn experimental AI ideas into high-availability, production-grade services.
• Take ownership of the end-to-end pipeline from data retrieval (RAG) and ingestion to monitoring token usage, cost, and latency.
• Design and build complex conversational states, multi-agent communication protocols, and the infrastructure that supports them.
• Champion engineering excellence and influence the org’s technical direction.

Requirements

• 10+ years of Experience: A proven track record in backend software development, including previous experience in a Tech Lead or Staff Engineer capacity
• Expert-level proficiency in GoLang in microservice architecture
• Hands-on experience building, deploying, and scaling AI-native applications in a production environment (not just local experiments)
• Deep knowledge of cloud platforms (Azure preferred) and container orchestration (Docker, Kubernetes)
• Strong understanding of event-driven architectures and high-concurrency systems

Nice to have

• Experience with LLM observability and evaluation frameworks (e.g., Langfuse, Arize Phoenix, or custom Golden Dataset evals)
• Proven ability to optimize RAG pipelines for both latency and cost (e.g., semantic caching, prompt engineering, or model distillation)
• Familiarity with building multi-agent workflows (e.g., using LangGraph, CrewAI, or similar)
• Experience building internal SDKs or libraries that help other engineering teams adopt AI features faster
