Senior Backend Engineer

Job Description

We’re looking for a Senior Backend Engineer to join Cyera’s CORE Engineering teams — a small, senior group responsible for the internal foundations on which the entire product is built. This is a high-impact, cross-organization role. Everything you build is used by 200+ engineers and affects every service in production: microservice frameworks, common services, databases, inter-service and cross-cluster communication, build and CI pipelines, deployment flows, and release processes — all at high scale, high speed, and production grade.

Job Responsibility

Design, build, and evolve core backend infrastructure with organization-wide impact
Own shared frameworks, services, and libraries used across the company
Work closely with multiple product teams as requirements, scale, and constraints change
Continuously improve systems to support growth, new use cases, and increased scale
Take full ownership of production systems, from design through deployment and operation
Build and evolve Cyera’s NestJS service framework and shared modules
Design and maintain application-level Kafka infrastructure and usage patterns
Contribute to and maintain Cyera’s TypeORM integration and internal fork
Implement and enforce global exception handling and service standards
Help define and evolve deployment standards across services
Own production-grade backend components designed for continuous growth and change
Design and evolve autoscaling mechanisms for async and event-driven workloads
Debug and resolve complex production issues across services
Improve database performance, scaling strategies, and migration safety
Continuously refine monitoring and alerting as system behavior evolves
Collaborate with DevOps and product teams on evolving infrastructure architecture
Ensure alignment between application code and continuous deployment infrastructure
Act as a technical partner to product teams building on CORE infrastructure
Participate in company-wide discussions on engineering standards and best practices
Contribute to and improve the company’s release processes
Support teams with safe, optimized migrations during continuous growth

Requirements

6+ years of experience in backend or core systems engineering
Strong experience building and operating large, evolving production systems
Proven ability to work effectively in fast-changing, ambiguous environments
Experience contributing to or owning shared frameworks, platforms, or internal tooling
Solid understanding of CI/CD, production operations, and observability
Strong collaboration skills and comfort working across many teams
High sense of ownership and responsibility for system outcomes

Nice to have

Experience in high-growth startups or scale-up phases
Background in CORE / infrastructure / internal engineering teams
Kafka-heavy or event-driven architectures
High-scale PostgreSQL environments
Familiarity with NestJS, TypeORM, or similar backend frameworks
Experience supporting large (200+), fast-growing engineering organizations
