Senior Software Engineer, Cloud

Job description

Lumana is on a mission to empower organizations by unlocking the value of their visual data — not just record the world, but to actually understand it and extract meaningful insights. Our AI video security platform delivers unmatched visibility and control, helping customers enhance security and safety, streamline operations, and respond instantly when it matters most. Founded in 2021, we are backed by tier-one Silicon Valley investors with deep team expertise in AI, computer vision, and machine learning. We are one of the fastest-growing video security companies and recently raised the largest Series A within our industry. We’ve built the most intelligent video security solution on the market — one that sees what matters, acts fast, and prevents what used to be inevitable. At Lumana, teams are small, dynamic, and trusted to lead. We think big, move fast, and execute like owners — because we are. Your impact here won’t be filtered. It will be visible, lasting, and real. 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. Qualifications Must Have: - 5+ years of experience in software engineering, with a focus on backend or cloud systems - A degree from a university in Computer Science, Computer Engineering, Electrical Engineering with a computing specialization, or a closely related field. - Requires hands-on experience with JavaScript / Node.js for backend systems. - Experience building backend services in cloud environments and working with cloud provider services and SDKs; GCP experience is a strong plus. - Strong understanding of distributed systems, concurrency, and scalability - Experience building APIs and microservices architectures - Familiarity with real-time systems or event-driven architectures - Excellent problem-solving and communication skills - Ability to work in a hybrid model in Israel, including at least 3 days per week in the office and collaboration across the team’s office rhythm, including periodic work from Caesarea. - Availability to contribute in an environment that may occasionally require remote support outside regular hours, including weekends or holidays when needed. Nice to Have: - Experience with video streaming pipelines or media infrastructure in the cloud - Preference for experience with streaming/data systems (e.g., Kafka, Pub/Sub, MQTT) - Knowledge of Kubernetes and orchestration systems - Solid understanding of Docker and containerization - Exposure to AI/ML pipelines or data platforms - Background in security best practices (IAM, encryption, secure APIs, zero trust) - NestJs or GO (Backend) ✍️ Lumana Hiring Philosophy We spend a lot of time building best-in-class products since we believe a highly differentiated product is easier to sell and support.
