Product Innovation: Implement and evolve real-time detection and decisioning flows within the Sightline Cyberfraud Defense platform, collaborating with security researchers, data science, and product teams.
Cloud-Native Operations: Build and operate services in a Kubernetes environment using a modern GitOps stack (Go, Kafka, Redis, MongoDB, BigQuery, ArgoCD, Pulumi, Crossplane), ensuring robust rollout strategies and safe migrations.
AI-Forward Engineering: Demonstrate a deep passion for the AI-first development frontier and an expert-level ability to leverage assistants and agents to radically accelerate the entire lifecycle - from architectural scaffolding to automated tasks, skills, and complex debugging/testing.
Cross-Functional Collaboration: Partner with adjacent teams to design end-to-end flows that balance security, performance, and customer experience.
Technical Leadership: Contribute to technical design reviews and code reviews, raising the bar for quality and operational excellence across the team.
Requirements:
Who you are:
Experience: 5+ years of experience building backend services with a strong grasp of modern distributed systems design.
Language Proficiency: High proficiency in at least one backend language such as Go, Java, or Scala, including a strong command of concurrency and multithreading concepts.
Cloud Infrastructure: Proven experience building and operating production systems in a major cloud provider (GCP or similar), including containerized workloads and CI/CD pipelines.
Data Systems: Hands-on experience with datastores and messaging systems (e.g., MongoDB, Redis, Kafka, or Postgres).
Networking & APIs: Solid understanding of networking fundamentals, HTTP-based services, and best practices for secure, reliable APIs.
Troubleshooting: Practical experience with monitoring tools (e.g., Prometheus, Grafana, Opsgenie) and resolving complex, distributed production issues.
Delivery: Comfortable working both independently on complex technical problems and as part of a collaborative team, driving projects end-to-end.
Nice to Have:
Previous experience in security, fraud detection, or risk scoring systems, especially in high-volume web or API environments.
Deep, hands-on experience with Go in production, including performance tuning, profiling, and optimizing latency-sensitive services for cost and availability at scale.
This position is open to all candidates.

Location: Tel Aviv-Yafo
Job Type: Full Time
We're building Cyber Threat Intelligence platform - an AI-first product that harvests, contextualizes, and serves threat intelligence at scale. We're looking for a Python-native backend engineer to own the infrastructure that makes this possible.
You'll design and build the systems that power both agentic AI workloads and large-scale data orchestration - exposing CTI insights as a service to UI components, APIs, and autonomous agents across the ecosystem. This is a greenfield opportunity where you'll shape foundational architecture decisions on a new product with a small, high-impact team.
The Responsibilities:
Build the tooling and infrastructure that enables AI agents to consume and reason over threat data.
Develop systems that harvest data from open and dark web sources, cross-reference signals, and contextualize raw intelligence into actionable insights.
Serve curated CTI data to various consumers - dashboards, internal services, and other agents in the platform.
Instrument complex workflows with tracing and metrics - when things break in production, we need visibility to understand why.
Design and scale agent-based systems along with robust evaluation frameworks.
Instrument complex workflows with tracing and metrics - when things break in production, we need visibility to understand why.
Create developer tooling and experiences that make the platform usable for other engineers building on top of it.
Requirements:
5+ years of backend development experience with Python.
Experience building and operating data pipelines, data lakes, or large-scale data infrastructure.
Experience with distributed systems and the challenges they bring (consistency, failure modes, debugging across services).
Familiarity with microservices architecture and tooling (Docker, Kubernetes).
Experience with NoSQL databases.
High independence - you thrive with autonomy and ownership in ambiguous environments.
Advantages:
Experience building distributed systems.
Data management at scale - ETL, data quality, governance.
Experience in cybersecurity, threat intelligence, or related domains.
Familiarity with AI/agentic application patterns.
Experience with graph and NoSQL databases.
- Startup or small-team experience.
This position is open to all candidates.
