Position: Principal Backend Java Engineer – Platform (CE100SF RM 3771)
Responsibilities

  • Architect, design, and build core backend services for data ingestion, APIs, and real-time event processing across applications, infrastructure, and IAM domains.
  • Develop event-driven pipelines integrating data from GitHub, SAST tools, AWS Cloud, CI/CD logs, and security scanners.
  • Define and maintain domain schemas (ECS-style) to normalize multi-source telemetry and enable correlation across app, infra, and identity data.
  • Implement and optimize NoSQL and graph-based persistence layers using Firestore, MongoDB, and Neo4j.
  • Build and secure multi-tenant APIs with robust authentication, RBAC, and contextual access control (OAuth2, JWT).
  • Collaborate with AI/ML and frontend teams to expose explainable, composable APIs that power Cognia's reasoning and visualization layers.
  • Design and oversee data contracts, event schemas, and message queues for inter-service communication.
  • Lead architecture discussions, perform code and design reviews, and mentor engineers on backend best practices.
  • Own DevOps integration for backend services — ensuring reliable deployment, observability, and scalability (AWS).
  • Define and enforce engineering standards, including API versioning, error design, security policies, and testing frameworks.
  • Define the architecture blueprint that supports the AI reasoning engine, telemetry ingestion, and explainable APIs
  • Establish customer's core backend foundation
  • Mentor engineers and raise the technical bar across the team.

Requirements

  • 8–10 years of backend engineering experience, with at least 3 years in microservices
  • Deep expertise in microservice architecture, RESTful API design, and asynchronous/event-driven systems.
  • Strong proficiency in Java
  • Experience architecting and scaling data-intensive SaaS platforms using Firestore, MongoDB, and Neo4j (or equivalent).
  • Proven experience building multi-tenant, secure systems with OAuth2, JWT, RBAC, and audit logging.
  • Solid understanding of cloud-native architectures — containerization (Docker), orchestration (Kubernetes), and CI/CD pipelines.
  • Hands-on experience with AWS and infrastructure automation (Terraform, Cloud Build, GitHub Actions).
  • Experience with Pub/Sub, Kafka, or other event-streaming systems for large-scale telemetry processing.
  • Strong background in secure API development, data modeling, and runtime observability (logging, metrics, tracing).
  • Excellent communication and mentoring skills — able to guide cross-functional teams and make sound architectural decisions with minimal oversight.

Bonus Skills

  • Experience with security data processing, AppSec, or DevSecOps tooling (e.g., Snyk, SonarQube, CodeQL).
  • Familiarity with RAG/LLM-based pipelines or AI-driven services (collaboration with AI/ML teams).
  • Exposure to GraphQL, gRPC, or OpenAPI-first design.
  • Understanding of data lineage, provenance, or knowledge graph architectures.
