[job_card.job_description]

provides the leading cloud platform for smart security and IoT, powering millions of home and business experiences. Our systems integrate devices, cloud services, APIs, and event-driven workflows into a unified ecosystem used by internal teams and external partners around the world.

The Device Lifecycle & Integrations (DELI) team builds the platforms and services behind the connected devices powering millions of homes and businesses.

Role Summary

We are hiring a Senior Software Engineer (Backend) to design and build foundational backend services, APIs, and event-driven pipelines that power ’s device integrations.

In this role, you will lead complex, high-impact engineering initiatives end-to-end with a high degree of autonomy—from technical design and implementation through deployment and ongoing operational support. You will coordinate across teams when your work intersects with shared systems, helping ensure integration models and data flows are consistent and technically sound.

As a senior engineer, you will help shape architectural improvements within your area, contribute to shared integration patterns, and ensure the systems you build have clear, meaningful indicators of impact and operational reliability. This is a hands-on role that works closely with Product Managers, TPMs, architects, and engineering teams to deliver robust, scalable systems designed for long-term clarity, reliability, and integration value.

This role combines hands-on engineering of mission-critical device integrations with opportunities to shape patterns and approaches used across a multi-domain platform serving millions of devices.

What You’ll Do

Design & Architecture

Design backend components, APIs, and event-driven workflows that are scalable, reliable, and easy for device providers and internal teams to integrate with.
Lead technical design for medium-to-large scoped features and components within the team’s domain.
Translate requirements into robust technical solutions aligned with platform architecture.
Contribute to consistent integration and data flow patterns used across device integration solutions.
Contribute to and influence shared architectural patterns that support long-term scalability and consistency across device integrations.

Implementation & Delivery

Write high-quality, maintainable, and well-tested code for backend services used in production at scale.

Build and optimize event-driven data pipelines (e.g., Kafka), ensuring reliability and performance under high load.

Deliver work through the full lifecycle : design → implementation → validation → iteration.

Diagnose and resolve complex production issues, implementing durable solutions that improve long-term stability.

Operational Excellence

Contribute to requirements for monitoring, alerting, and operational readiness to ensure systems remain healthy.

Partner with SE-Ops and engineering teams to ensure observability and support processes reflect real integration needs.

Support DELI's work to define and operationalize device integration success metrics, helping determine meaningful indicators of integration outcomes.

Collaboration & Mentorship

Mentor engineers not only on technical implementation, but also on architectural thinking and delivery practices that scale.

Work closely with Product Managers, TPMs, and architects to ensure technical decisions support integration outcomes and platform consistency.

Participate in cross-team technical discussions, surfacing dependencies, risks, and design considerations early.

Impact Across the Organization

Identify opportunities to improve service reliability, event flows, and integration consistency.

Contribute to documentation, architectural patterns, onboarding guides, and engineering best practices.

Clearly articulate and justify design decisions in terms of both technical tradeoffs and business impact.

What We’re Looking For

Required Qualifications

Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience.

5–8+ years of backend software engineering experience.

Proven experience leading multi-engineer projects from architecture through delivery with a high degree of independence.

Proven ability to explain complex technical concepts clearly and empathetically across engineering and product teams, and to document architectural decisions for long-term clarity and maintainability.

Strong proficiency in an object-oriented language (C#, Java, or Python).

Experience building and maintaining RESTful or gRPC APIs.

Hands-on experience with event-driven systems (Kafka or similar).

Strong understanding of relational databases and data modeling.

Ability to debug complex systems and apply observability best practices.

Experience using AI-assisted development tools (e.g., GitHub Copilot, ChatGPT) to streamline development while maintaining engineering standards.

Ability to review and validate AI-generated code, tests, and documentation for correctness and maintainability.

Strong communication skills.

Preferred Qualifications

Strong experience with .NET / C# and SQL Server is strongly preferred, as this is the foundation of our backend stack, though equivalent experience in similar ecosystems may translate well.

Proficiency in Test-Driven Development (TDD) and automated testing frameworks (unit, integration, end-to-end).

Experience supporting internal and external integration consumers.

Experience operating large-scale distributed systems in production.

Familiarity with caching layers, stream processing, or distributed messaging.

Experience with CI / CD pipelines, containers (Docker / Kubernetes), or cloud platforms.

Familiarity with AI-powered IDE tooling or code analysis tools to support refactoring, debugging, and test generation.

Experience using the Model Context Protocol (MCP) to build or integrate AI agents that interact with REST APIs.

Experience developing or influencing reusable architectural patterns.

Understanding device communication protocols and experience overseeing large IoT device fleets.

The Impact You’ll Have

You’ll build backend systems that directly shape how devices integrate with ’s platform.

You’ll influence technical direction within a team focused on device-facing reliability, consistency, and scale.

You’ll help define integration and operational patterns that scale across many types of devices and internal teams.

You’ll take on substantial ownership of impactful backend systems used across the company.

Please note that sponsorship of new applicants for employment authorization, or any other immigration-related support, is not available for this position at this time.
