Sr Adv Software Engineer

Resideo is growing a new software development organization focused on reinventing the smart home through software services and connected IoT products. Our platforms support millions of users and a rapidly expanding ecosystem of devices.

As a Senior Advanced Software Engineer, you will serve as a technical leader and architect for business‑critical cloud and IoT platforms. You will define architecture, influence technical strategy across teams, and ensure solutions scale securely and reliably as the platform grows. This role combines deep hands‑on engineering with organization‑level technical leadership.

You will be involved across the entire system lifecycle - from early concept and architecture definition through production operations and end‑of‑life - while mentoring engineers and raising the technical bar across the organization.
JOB DUTIES:

• Act as a technical lead and architect for highly scalable, low‑latency backend services and APIs supporting consumer and professional smart‑home experiences
• Define, evolve, and communicate cloud and IoT platform architecture, ensuring alignment with long‑term business and product strategy
• Design and lead the implementation of highly distributed, fault‑tolerant cloud systems operating at global scale
• Provide architectural leadership for IoT device connectivity, data ingestion, and event‑driven processing pipelines
• Drive technical roadmap planning, balancing feature delivery with reliability, scalability, and maintainability
• Lead design reviews and architectural decisions across teams, identifying risks and proposing durable solutions
• Champion software quality, security, performance, and operational excellence across the platform
• Partner with product management, security, and operations to deliver robust, customer‑centric solutions
• Mentor and develop engineers, serving as a technical role model and trusted advisor
• Contribute hands‑on to complex or high‑risk engineering efforts while enabling teams to execute effectively

YOU MUST HAVE: 

• 7+ years of experience building and operating large‑scale, consumer‑facing or IoT software platforms
• Demonstrated experience leading architecture and design of complex, distributed systems
• Deep expertise in C# and .NET with strong knowledge of secure, cloud‑native application development
• Proven ability to design and deliver highly available, performant, and fault‑tolerant services
• Experience designing systems that handle high‑volume event streams and request traffic
• Track record of technical leadership and influence across multiple teams or initiatives

WE VALUE: 

• Expertise building and operating containerized platforms using Docker and Kubernetes at scale
• Strong experience with CI/CD pipelines, automation, and DevOps best practices
• Deep commitment to testing and quality, including unit, integration, and system testing
• Strong grounding in distributed systems architecture (messaging, workflows, sagas, load balancing)
• Experience designing Active‑Active and multi‑region systems
• Proficiency with RESTful APIs, JSON, and modern service‑to‑service communication patterns
• Cloud platform expertise (Azure preferred; AWS acceptable)
• Knowledge of networking protocols (HTTP, gRPC, MQTT, TCP/UDP)
• Experience with event streaming and messaging platforms (EventHub, Kafka, Kinesis, RabbitMQ, SQS)
• Experience with relational and non‑relational databases (SQL Server, Postgres, Cosmos DB, MongoDB, DynamoDB)
• Proven experience operating mission‑critical production systems, including incident response and root‑cause analysis
• Experience developing IoT device platforms and large‑scale client‑facing APIs
• Ability to communicate complex technical concepts clearly to both technical and non‑technical stakeholders
• Strong collaboration skills and a passion for engineering excellence

WHAT'S IN IT FOR YOU:

• Opportunity to shape the technical direction of a global IoT platform
• Significant influence on architecture, tooling, and engineering standards
• Collaboration across a diverse, global organization
• Work on a full‑stack, cloud‑based security and smart‑home platform
• Competitive benefits including healthcare, retirement plans, paid time off, and holidays
