Agentic Backend Engineer (Golang)

As an Agentic Backend Engineer, you will play a critical role in shaping the next generation of software development at fiskaly. Instead of focusing primarily on writing code, you will design AI-driven systems that build, test, and deploy microservices autonomously. This role centers on agentic engineering, where AI agents handle most of the development lifecycle while you architect the systems that guide, verify, and improve their output.

The expected approach follows the 90/10 principle: 90% of the time:

designing agent frameworks, orchestration logic, system architecture, prompts, and verification loops. 10% of the time:

hands-on coding for complex edge cases, final refinements, and critical logic that requires human expertise.

You will contribute to the client’s SaaS platform powering digital receipts and tamper-proof fiscal transactions, ensuring the systems remain secure, reliable, and compliant.

Key Responsibilities: Agentic Orchestration Design and implement multi-agent workflows that automate the software development lifecycle. Work with frameworks such as LangChain, LangGraph, or custom Golang-based orchestrators. Autonomous System Development Build systems capable of transforming high-level requirements into production-ready Golang microservices. Agent-Friendly Architecture Design APIs and system boundaries that are optimized for LLM interaction and autonomous code generation. Ensure agents can navigate and extend the codebase reliably without introducing hallucinated logic. Reliability & Verification Develop automated validation systems and \"Judge agents\" that audit generated code. Ensure strict compliance with fiscal security and digital signature requirements. Human-in-the-Loop Design Define critical checkpoints where human expertise is required to ensure quality, safety, and compliance. Infrastructure & Distributed Systems Work within cloud-native environments and Kubernetes-based architectures to integrate agentic workflows into existing infrastructure.

KPIs / Success Metrics: Successful implementation of agent-driven microservice generation pipelines Reduction of manual coding effort through effective AI orchestration Stability and reliability of generated systems meeting production standards Compliance with fiscal and digital signature security requirements Improved development velocity through agentic automation frameworks Maintainability and extensibility of the agent-friendly architecture
