Senior Software Engineer

About us: 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 Senior Software Engineer (Rust), you'll play a key role in building the core of our next-generation cybersecurity platform — a distributed system that connects, protects, and manages IoT and edge devices at scale. You'll design and implement high-performance backend services, APIs, and platform components using Rust, ensuring security, scalability, and reliability at every layer. You'll work closely with our product, DevOps, and security teams to create a cloud-native platform that seamlessly bridges embedded environments and large-scale infrastructure. This role combines deep technical work with real architectural ownership: you'll make decisions that directly shape the foundation of our technology and define how secure systems are built for years to come. Responsibilities: Design and maintain Rust-based backend and edge components that power secure communication and device orchestration. Build scalable APIs and asynchronous microservices using Rust's modern ecosystem. Architect for reliability, observability, and performance at scale. Integrate cybersecurity features directly into the platform - from authentication and encryption to telemetry and secure provisioning. Contribute to architectural decisions driving modularity, maintainability, and long-term evolution. Prototype, benchmark, and optimize system components to improve performance and resource efficiency. Mentor teammates, uphold high engineering standards, and foster a security-first culture. Requirements: 6+ years of experience in backend or platform engineering, building large-scale or distributed systems. Strong proficiency in Rust, including asynchronous programming, memory safety, and concurrency. Solid understanding of distributed architectures, API design, and inter-service communication (REST, gRPC, or message streaming) Experience with Docker, Linux, and cloud deployment (AWS or equivalent). Familiarity with PostgreSQL, Redis, and message streaming systems such as Kafka or NATS. Deep understanding of security principles (authentication, encryption, identity, data protection). Hands-on experience with CI/CD, automated testing, and observability tools (metrics, tracing, logging). Strong software engineering practices: clean code, testing, documentation, and peer review. Ability to own complex systems end-to-end, from design through production operations. Nice-to-have: Familiarity with Test-Driven Development (TDD) principles and practices. Experience with functional programming paradigms (e.g., immutability, pure functions). Contributions to open-source Rust projects. Background in cybersecurity, IoT, or edge computing platforms. Why Join Us? Join a team shaping the future of secure IoT and embedded technology worldwide. Build next-generation cybersecurity solutions that protect data, devices, and users at scale. Work across Rust, Linux, distributed systems, and edge computing — solving complex challenges that push performance and reliability. Influence architecture, product strategy, and key engineering choices from day one. Take ownership, expand your skills, and advance your career in a fast-moving international environment. Work alongside passionate engineers and researchers who value precision, curiosity, and impact. Experience a flexible, inclusive workplace built on trust, creativity, and genuine collaboration.
