Back End Developer

Position: Core Engineer — Backend & Infrastructure | Defense Technology (Stealth-Stage Startup)

We are a stealth-stage defense technology company operating at the intersection of Cybersecurity, Open Source Intelligence, and Generative AI. Our platform is designed to transform large-scale, unstructured digital environments into actionable intelligence — and we are seeking a senior backend engineer to help architect the foundation on which it is built.

This is a founding-team position. The successful candidate will take full ownership of the core backend infrastructure, bridging the gap between AI-driven logic and robust, low-latency systems capable of operating across elite cloud environments and sensitive on-premise infrastructure.

Responsibilities

The role encompasses the design and implementation of scalable microservices forming the backbone of our OSINT engine; development and maintenance of complex, event-driven state machines to manage intricate data lifecycles and asynchronous workflows; deployment and management of high-availability Kubernetes clusters across both cloud and on-premise environments; collaboration on the integration of on-premise, no-API AI solutions into high-performance production pipelines; and end-to-end ownership of CI/CD infrastructure, with a strong emphasis on automation, security, and deployment integrity.

Qualifications

Candidates should possess a minimum of five to seven years of professional experience in backend development, with a demonstrable record of delivering production-grade systems; deep proficiency in Python — specifically FastAPI and Celery — or equivalent high-performance backend languages; proven expertise across major cloud ecosystems, including AWS, GCP, or Azure, as well as hands-on experience managing on-premise infrastructure; production-level experience with Kubernetes, including container networking and persistent storage; a strong architectural understanding of event-driven design, idempotency, and distributed systems; and a security-first engineering philosophy with a working knowledge of cybersecurity principles.

The following will be considered advantageous: experience with vector databases such as Milvus, Qdrant, or Weaviate; a background in data engineering or high-volume data pipeline construction; and prior experience within the Israeli technology ecosystem or elite military technology units.

What We Offer

As a member of the founding core team, the selected candidate will exercise meaningful influence over the technology stack, architecture, and company culture from inception. The role offers significant technical complexity, full autonomy, and the opportunity to contribute to a product of genuine consequence in the global security landscape.

Qualified candidates are invited to apply via direct inquiry through LinkedIn messaging.
