We’re looking for a Back-End Engineer to design, build, and operate the services that power Elisity’s microsegmentation platform. You’ll work across our core backend
-Java services, Kafka-based event streaming, and PostgreSQL data stores
-building reliable, scalable systems that turn device intelligence and flow data into real-time policy decisions. This is a hands-on engineering role focused on system design, data correctness, and production reliability.

What you’ll do

• Design and build backend services in Java that ingest, process, and serve device-identity and network-flow data at scale.
• Own event-driven pipelines on Kafka
  -model topics, partitioning, ordering, and delivery guarantees so data flows reliably between services.
• Design and evolve PostgreSQL schemas for high-throughput, query-heavy workloads, and tune for performance, correctness, and safe migrations.
• Build and maintain APIs that other services and the product surface consume, with clear contracts and versioning.
• Make services production-ready: instrumentation, metrics, alerting, and the SLOs you’ll stand behind.
• Diagnose and resolve performance, scaling, and reliability issues across the data plane.
• Partner with architects, product owners, and other engineers to turn feature intent into well-scoped, buildable work.
• Contribute to code review, technical design discussions, and engineering standards.

What We’re Looking For

• Strong backend engineering experience building production services in Java.
• Hands-on experience with Kafka (or comparable streaming/messaging systems) - you understand topics, partitions, consumer groups, and delivery semantics.
• Solid PostgreSQL skills
  -schema design, indexing, query optimization, and safe migrations under load.
• A track record of building scalable, reliable distributed systems and reasoning about failure modes.
• Comfort owning services end to end, including observability and on-call-grade reliability.
• Clear communication and the ability to collaborate across a remote engineering team.

Nice to Have

• Experience in network security, device identity, or microsegmentation — or an adjacent security/networking domain.
• Experience with cloud-delivered, multi-tenant SaaS platforms.
• Familiarity with analytics or data-plane workloads, and large-scale data processing.

Why You’ll Love Working Here

• 100% remote with flexibility and trust.
• High-impact role in a fast-growing scaleup environment.
• Modern, cutting-edge tech stack with real room to experiment.
• Strong ownership and influence over backend and system-design decisions.
• Supportive, collaborative team that values learning and initiative.
