Senior Software Engineer

Artemis is building the future of AI‑driven defense – helping companies detect and defend themselves effectively in an era where AI is fighting AI on the cyber battlefield. We’re backed by First Round Capital, Brightmind, and a group of the cybersecurity industry’s most prominent operators. Our founders, Shachar (ex‑Palo Alto Networks, AWS, Demisto) and Dan (ex‑Abnormal Security, Twitter), have previously built, launched, and scaled cybersecurity products loved and trusted by tens of thousands of customers, and have the customer, technology, and security know‑hows to deliver this vision.

Our exceptionally strong founding team includes software engineers, AI researchers, security engineers, and product designers hailing from Google, Abnormal AI, Wiz, Meta, AWS, and Sentinel One. We are growing our team and looking for passionate builders to join us and support our expanding customer base.

Artemis ingests and analyzes exabytes of streaming data from cloud platforms, identity providers, network logs, and more. We’re building a new, large‑scale data platform from the ground up – and we’re looking for an exceptional Distributed Systems Software Engineer to help shape and build it. In this role, you’ll work alongside engineers who architected some of the world’s biggest distributed systems.

You will help design, build, and scale the core systems that power Artemis AI analytics engine including data ingestion, normalization, enrichment, detection, and federated analytics. You’ll make key architectural decisions, drive performance and reliability at scale, and ensure our systems remain secure and cost‑efficient as we 100× our customer base. This is a rare opportunity to join at the foundation of a greenfield project and define how a world‑class distributed data platform is built.

• Design and implement large‑scale distributed systems for log ingestion, normalization, and enrichment. Build the foundation that transforms massive volumes of raw security telemetry into structured, enriched data ready for analytics – leveraging modern data lake and streaming technologies to support near‑real‑time ingestion at scale.
• Architect and optimize data storage and retrieval for exabyte‑scale workloads. Make key architectural decisions that enable efficient queries across distributed and federated data sources.
• Build federated analytics and streaming infrastructure that retrieves logs dynamically, including designing real‑time pipelines, event‑driven services, and scalable processing layers to support multi‑stage detection and correlation scenarios.
• Develop and maintain a reliable detection engine in partnership with our detection engineering team. Implement and optimize query‑driven detectors across massive data sets, ensuring consistent performance, high availability, and accuracy.
• Implement intelligent, agentic workflows. Collaborate with our AI/ML team to integrate large‑language models into the data and detection pipeline. Design systems that support iterative experimentation, safe deployment, and continuous improvement of AI‑driven detection.

• Proven experience designing, building, and operating large‑scale distributed systems and data infrastructure. Built and debugged complex, high‑throughput data pipelines – not just consumed them – and comfortable with modern data lake and streaming technologies to handle massive volumes of security and telemetry data efficiently.
• Proficiency with using cloud platforms (AWS, GCP or Azure) and container orchestration (Kubernetes, ECS) for analytics systems.
• Experience with distributed databases and data‑warehouse technologies (Click House, Snowflake, Big Query, Apache Iceberg), caching (Redis/Memcached), and message queues (Kafka, Pulsar).
• Bonus: background in cybersecurity, SIEM or endpoint detection; knowledge of security data formats like OCSF and entity representations.

• Make a real world impact – help empower cybersecurity teams around the world to keep people safe from the most advanced cyber threats.
• Be challenged to be better than ever before – our team includes some of the smartest and most driven people in the…
