Senior Software Engineer, Cloud

Lumana helps organizations turn video into action. Our AI video security platform helps customers improve safety, strengthen security, and respond faster when it matters most.

Founded in 2021 and backed by leading Silicon Valley investors, we’re growing quickly. Here, you’ll think big, move fast, and own work that has a visible impact.

Role Description

The Software Engineer - Cloud will join a foundational and growing cloud team with meaningful ownership over critical platform areas. You will help build the software systems behind a hybrid edge-cloud architecture powering real-time video streaming, recording, and AI processing at global scale. This role sits within the team led by the Head of Cloud, which owns a broad software domain across cloud, mobile, web applications, and related clients.

You’ll work on a distributed backend ecosystem that connects edge devices with cloud services and customer-facing applications, with a strong focus on performance, reliability, and low-latency user experiences. This is a strong fit for an engineer who enjoys meaningful ownership, thrives in a fast-moving startup environment, and is comfortable contributing to systems that support customers worldwide. You will have a chance to work alongside teammates across the U.S., Israel, and Europe, contributing to a platform with broad impact and increasing customer demand.

Location & Travel

• Hybrid Schedule:

  • Two days a week working from home.

  • Ramat Gan office, located just outside Tel Aviv and close to the train station.

  • Includes biweekly travel to our Caesarea office.

Responsibilities

• Build and evolve the core cloud platform that supports real-time video streaming, recording, and AI processing across a global customer base.

• Design, develop, and maintain distributed backend services that connect edge infrastructure with cloud systems and customer-facing products.

• Develop and support data pipelines for both real-time and batch processing of video and AI-related workloads.

• Work on systems responsible for ingestion, storage, retrieval, and secure handling of large-scale video data in a multi-tenant environment.

• Architecting multi-tenant, highly available systems across regions in a cloud environment

• Collaborate closely with Edge engineers and adjacent teams to enable seamless integration across the broader platform.

• Use cloud provider services and SDKs as part of day-to-day development, including work across core cloud capabilities rather than a single isolated service.

• Contribute to backend development in JavaScript/Node.js and, depending on background and team fit, potentially support growing work in Go as part of the cloud stack.

• Participating in code reviews, debugging, and optimizing performance across distributed systems

• Help support a production environment where reliability matters, including situations that may require responsiveness outside standard hours when cloud issues have broad impact.

• Our infrastructure is powered by Google Cloud.

• Other duties may be assigned.

We don’t do cookie-cutter. If you’ve got the grit, the drive, and the track record-especially in security or AI-we want to hear from you. Even if you don’t check every box, let’s talk.
