Senior Software Engineer, IoT Platform

Founded by ex-Apple Product and Engineering leaders , Level is redefining the smart home with technology that is simple, intuitive, useful, and invisible. At Level, we take a unique approach to designing products - one that shifts focus from what we make to how we make it and who we make it for. It’s an approach that results in elegant and unique solutions, raising the bar for the entire smart home ecosystem.

Now part of the Assa Abloy family, a global leader in access solutions, Level is positioned to accelerate innovation and expand our reach even further. This partnership strengthens our ability to deliver world-class smart home experiences while maintaining the vision and design excellence that have always set us apart.

About the role

As a Senior Software Engineer on our Platform team, you will tackle complex system design challenges to build and enhance the backbone of our platform. You'll design and implement scalable, fault‑tolerant services that process high‑volume real‑time data, ensure synchronization across hundreds of thousands of IoT devices, and deliver seamless user experiences to hundreds of thousands of residents and property managers.

Projects our Platform team is working on

• Pioneering a new device platform:
Architect the foundation for Level’s expansion into video doorbells and future smart home devices, creating a robust ecosystem that will support third‑party integrations and open up new possibilities in home automation.

• Building scalable data analytics pipelines:
Develop robust systems to process and analyze large amounts of IoT telemetry data, enabling us to derive actionable insights and improve our products continuously.

• Creating a cutting‑edge device management platform:
Architect a system that allows for safe, observable, and incremental rollouts of software updates to hundreds of thousands of IoT devices, ensuring reliability and performance at scale.

These projects offer exciting challenges in distributed systems, real‑time data processing, and large‑scale IoT device management. You’ll have the opportunity to make a significant impact on the future of smart home technology.

We’re looking for engineers who can break down these ambiguous problems, design elegant solutions, and drive them from prototype to production. You’ll collaborate closely with other engineers, product managers, and stakeholders to define the future of our platform.

Our tech stack includes Golang, Python, Kubernetes, Kafka, Redis, Postgre

SQL, AWS Lambda, and more. We’re looking for engineers who are excited to learn new technologies and contribute to our evolving architecture.

What you’ll do

• Design and implement:
Contribute to the architecture of our core platform services, focusing on scalability, reliability, performance, and maintainability. Participate in technical discussions and help shape the implementation of new features.

• Solve challenging problems:
Address complex issues in distributed systems that handle real‑time data processing at a scale of hundreds of events per second, device synchronization, and IoT security. Ensure the robustness and resilience of all services.

• Write high‑quality code:
Develop clean, efficient, and well‑tested code. Contribute to shared libraries and set coding standards for excellence.

• Collaborate and communicate:
Engage with cross‑functional teams to precisely define requirements, explore technical possibilities, and deliver high‑impact features. Communicate your designs and decision‑making process clearly to both technical and non‑technical stakeholders.

• Own and deliver:
Take full ownership from design through deployment to ongoing operation, making informed, data‑driven decisions and adapting based on operational feedback.

• Uplevel the team:
Mentor and develop junior engineers, fostering a culture of technical excellence, continuous improvement, and psychological safety.

Qualifications required to succeed in this role

• System design and architecture:
