Rust Engineer – AI Agents development

At Exein, our mission is to build the world’s first ecosystem for IoT device security, ensuring all types of devices are secure globally. Our dynamic team is passionate about data, machine learning, open source, and firmware. We constantly work to secure millions of devices, making daily life safer for everyone. Our unique products empower developers to secure their IoT devices with cutting-edge technology in an easy and frictionless way.

Job Overview

As a Rust Engineer focused on AI Agent Development, you will play a key role in designing and building the core intelligence layer of our next-generation cybersecurity platform.

Your primary mission will be the development of distributed, production-grade AI agents capable of autonomous reasoning, decision-making, orchestration, and secure interaction across IoT and edge environments.

You will architect and implement the backend systems that enable AI agents to operate reliably at scale — integrating LLMs, reasoning pipelines, telemetry streams, and secure device communication into a cohesive, high-performance platform.

This role includes strong architectural ownership, shaping how our AI-driven cybersecurity platform evolves across multiple products and real-world deployments.

Responsibilities

• Design and develop the core AI Agent framework powering autonomous cybersecurity capabilities.
• Implement high-performance backend services in Rust to support agent execution, state management, and distributed coordination.
• Design robust APIs enabling secure interaction between agents, devices, and external services.
• Architect event-driven infrastructures that allow AI agents to process telemetry and trigger real-time actions.
• Develop memory architectures (short-term, long-term, contextual) for AI agents operating in dynamic environments.
• Integrate LLMs and reasoning engines into production-safe, observable, and controllable systems.
• Ensure reliability, observability, and security of agent pipelines (metrics, tracing, logging, guardrails).
• Model complex multi-tenant data systems supporting AI-driven workflows across products.
• Collaborate with security, product, and DevOps teams to ensure safe deployment of AI-driven capabilities.
• Drive architectural decisions regarding the AI platform's modularity, extensibility, and long-term evolution.

Requirements

• 6+ years of experience in backend, distributed systems, or platform engineering.
• Strong proficiency in Rust, with deep knowledge of concurrency, performance, and systems design.
• Experience designing and deploying AI-powered systems or agent-based architectures in production.
• Solid understanding of LLM integration patterns, reasoning loops, tool-use frameworks, and AI orchestration.
• Experience building event-driven or message-based distributed systems.

Nice to Have

• Strong API design skills (REST/gRPC), including versioning and cross-service communication.
• Experience with data modeling for complex, multi-tenant or multi-product environments.
• Familiarity with telemetry pipelines and high-throughput data processing.
• Deep understanding of distributed systems, cloud-native architectures, and Linux environments.
• Experience with Docker, CI/CD pipelines, and cloud platforms (AWS or equivalent) is preferred.
• Strong understanding of security principles, including authentication, encryption, identity management, and safe AI deployment practices.
• Ability to own systems end-to-end, from architecture to production operations.
• Background in cybersecurity, IoT, or edge computing is preferred.

Why Join Us?

• Build real-world AI Agents that operate in high-impact cybersecurity environments.
• Shape the architecture of a production-grade AI platform from the ground up.
• Work at the intersection of Rust, distributed systems, AI orchestration, and security.
• Tackle complex challenges around safe autonomy, scalability, and real-time reasoning.
• Influence product direction and core architectural decisions from day one.
• Collaborate with engineers and researchers pushing the boundaries of AI in security.
• Grow in a fast-moving, international environment focused on innovation and technical excellence.
• Join a flexible, inclusive workplace built on trust, curiosity, and meaningful impact.

Location

Remote (Europe). Candidates based in Rome and able to work from the office, or willing to relocate to Rome, are preferred.
