Software Engineer - Over-the-Air Updates

Responsibilities

• Design and develop scalable OTA update platforms that process and distribute software packages, firmware updates, and configuration changes to large fleets of connected devices using modern cloud-native architecture in C++ and Go
• Architect and implement secure update delivery pipelines using technologies like cryptographic signing, encrypted communication channels, and authentication systems to ensure update integrity and prevent unauthorized modifications
• Build and maintain cloud-based OTA infrastructure leveraging distributed systems, containerization with Docker, and orchestration frameworks to support high-volume, low-latency package distribution
• Develop versatile package management systems for handling versioning, dependencies, and distribution of software components across diverse device ecosystems
• Create efficient content delivery networks (CDNs) optimized specifically for package distribution to ensure fast and reliable updates even in bandwidth-constrained environments
• Work on advanced monitoring and analytics systems that track update success rates, performance metrics, and provide real-time visibility into OTA campaign status across global device deployments

Requirements

• 4+ years of experience in distributed systems development with strong proficiency in C++ and Go, and experience building scalable cloud-native applications
• Experience with cloud platforms and DevOps practices including AWS, Azure, or GCP services, along with CI/CD pipelines, infrastructure as code, and containerization technologies
• Knowledge of secure software deployment including cryptographic signing, certificate management, encrypted communication protocols, and understanding of security best practices for remote updates
• Manage packages for various types of devices running embedded Linux and real-time operating systems, implementing efficient deployment strategies for diverse hardware platforms
• Proficiency in cloud-native development with microservices architecture patterns, API design, and service mesh technologies for building resilient distributed systems
• Understanding of CDNs and package delivery networks (PDNs) for efficient global distribution of software updates

Nice to Have

• Experience with OTA frameworks and tools such as Mender, RAUC, SWUpdate, or similar platforms for managing firmware and software updates
• Experience with Go's cloud development ecosystem including Go Cloud, gRPC, and other tools for building portable cloud applications
• Proficiency with distributed database systems for managing device inventories, update states, and telemetry data across large-scale deployments
• Understanding of fleet management systems and experience with device monitoring, remote diagnostics, and large-scale device lifecycle management
• Knowledge of security frameworks and compliance including experience with penetration testing, vulnerability assessment, and adherence to cybersecurity standards
• Experience with infrastructure as code (IaC) tools like Terraform or CloudFormation for automating cloud resource provisioning and management
• Collaborate with cross-functional teams including DevOps engineers, security specialists, product managers, and device firmware teams to deliver comprehensive OTA solutions
