Sr Software Engineer

Role Description

Own platform-level technical decisions for distributed cloud components and microservices using C#, .NET Core, MVVM, and related frameworks, applying object-oriented design and SOLID principles.

• Lead and mentor the development team, overseeing project execution, code quality, and technical delivery.
• Design, develop, and optimize real-time data pipelines between IoT devices, gateways, and cloud platforms using MQTT, WebSocket, SignalR, Redis, TCP/IP, and Kafka, leveraging Rust where performance and concurrency optimization are critical.
• Define and implement REST APIs and microservice architectures for large-scale IoT deployments, ensuring high availability, performance, and maintainability.
• Oversee cloud infrastructure deployment and operations (AWS or equivalent), including EC2, Lambda, Route 53, Cognito, RDS, ELB, and CloudWatch, to ensure fault tolerance, scalability, and reliability.
• Design and manage LoRaWAN networks, LNS systems, and the network and communication layers for other IoT protocols, including device provisioning, messaging, and network optimization.
• Design and implement scalable, high-performance data systems using MySQL and exposure to Cassandra or equivalent databases for telemetry and analytics workloads.
• Drive technical strategy for web interfaces and dashboards, enabling device management, configuration, and real-time visualization.
• Lead IoT security efforts, including secure coding practices, and coordinate with the security team on penetration testing, vulnerability scanning, and remediation.
• Ensure platform compliance with ISO 9001 standards and implement ISO-compliant software development processes.
• Collaborate cross-functionally with embedded, DevOps, security, product management, business, and customer teams to define platform architecture, device-cloud integration strategies, and roadmap priorities.
• Provide senior-level technical guidance and Level 3 support for production IoT systems, resolving complex issues affecting cloud platforms and device networks.
• Develop and execute automated unit and integration tests (e.g., NUnit) to ensure code quality, reliability, and adherence to ISO-compliant development processes.
• Document platform architecture, operational procedures, and design decisions to support internal knowledge, regulatory compliance, and continuous improvement.
• Participate in Agile planning and governance, influencing process improvements, technical strategy, and prioritization of work to ensure timely project delivery.

Qualifications

• Bachelor’s degree or equivalent in Computer Science, Computer Engineering, or a related field.
• 5 years of related, progressive, post-baccalaureate experience.

Requirements

• Architecting and developing cloud-native IoT software platforms using C# (.NET 6 or later) and applying object-oriented design and SOLID principles.
• Designing and managing real-time data pipelines between IoT devices, gateways, and cloud platforms using MQTT, WebSocket, SignalR, Redis, TCP/IP, and Kafka.
• Configuring and managing LoRaWAN networks, LNS systems, including device provisioning, messaging, and network optimization.
• Deploying, managing, and monitoring cloud infrastructure (AWS or equivalent), including services such as EC2, Lambda, Route 53, Cognito, RDS, ELB, and CloudWatch, to ensure reliability, scalability, and fault tolerance.
• Implementing and optimizing data persistence layers using MySQL and exposure to Cassandra or equivalent distributed and relational databases for scalable IoT data storage.
• Designing and implementing distributed REST APIs and microservice architectures for multi-tenant, high-throughput IoT platforms.
• Applying secure software development practices, coordinating with security teams on vulnerability scanning, penetration testing, and remediation.
• Developing and executing automated unit and integration tests (e.g., NUnit) to ensure code quality, reliability, and compliance.
• Experience with ISO 9001-compliant software development processes and familiarity with ISO design principles.

Benefits

• Telecommuting available from anywhere in the US.
• Salary: $145,018/year.
• Full-time position.
