Software Dev Principal Engineer - Cloud-Native Microservices & Network SecurityAbout the Role

SonicWall is a global leader in cybersecurity, offering firewalls, secure access solutions, and threat intelligence that protect millions of networks for enterprises, governments, and service providers worldwide. SonicWall’s portfolio includes next-generation firewalls (NGFW), centralized management, wireless network management, secure mobile access, cloud security, and endpoint security. All these solutions are coordinated and managed through SonicWall's Unified Management (UM) architecture.

We invite you to join our team in developing innovative network security management solutions for SonicWall's Network Security Manager (NSM), a centralized management and analytics platform within the SonicWall Unified Management (UM) ecosystem. In this role, you will help build secure and scalable software capabilities that integrate with SonicWall's Unified Management (UM) platform and Shared Services Platform (SSP) to meet the unique operational needs of enterprise customers, Managed Service Providers (MSPs), and Managed Security Service Providers (MSSPs) around the globe.

You will design and build cloud-native and on-premises microservices, RESTful APIs, real-time communication layers, and frontend components that power NSM's security policy management, device orchestration, and network visibility features. This role spans backend-first full-stack development and demands a security-first engineering mindset, strong Go proficiency, and the ability to leverage AI-assisted development tools responsibly and critically.

You will work as part of a globally distributed engineering team across India, USA, and other development centres, collaborating cross-functionally with engineers, QA, and product teams to deliver high-quality features in an agile, fast-paced environment.

  • At least 10 years of related experience with a Bachelor’s degree; or 8 years and a Master’s degree; or a PhD with 6 years’ experience; or equivalent experience preferred  
  • Degree in Computer Science, Engineering, or related field preferred
Responsibilities
  • Defining technical strategy/architecture direction.
  • Mentoring and growing senior engineers, and driving engineering standards adoption
  • Collaborate with AI coding tools - validating, testing, debugging, refining generated code, establishing coding standards and AI guardrails.
  • Lead end-to-end system design — from requirements decomposition through to deployment topology, data modelling, and API contracts
  • Collaborate with engineering managers and product leads on roadmap feasibility, effort estimation, and technical risk assessment
  • Design, develop, and maintain high-performance Go-based microservices for NSM's cloud and On-Prem deployments
  • Build and evolve RESTful API endpoints serving enterprise customers at scale
  • Implement and maintain certificate-based connection trust (mTLS) for secure service-to-service and client-to-service communication
  • Adopt a secure software development framework and ensure that the software development process addresses the OWASP Top 10 risks from design to delivery.
  • Instrument software services with structured logging, distributed tracing, and metrics using Open Telemetry, New Relic, and OpenSearch
  • Contribute to both cloud-native (AWS/Kubernetes) and On-Prem microservice deployments, ensuring feature and security parity
Required Skills
  • AI-Assisted Coding: Proficient use of AI coding tools is expected as a force multiplier applied with engineering rigor.
    • Critical validation - Identify and fix security vulnerabilities, logic errors, and inefficiencies in AI-generated code.
    • Iterative collaboration - Work with AI to refine, test, and improve code in small, reviewable chunks rather than accept large, unreviewed outputs.
  • Secure Coding - Hands-on knowledge of the OWASP Top 10, threat modelling and secure design code review.
  • System Design
    • Ability to design distributed systems at scale
    • Experience designing multi-tenant SaaS architectures
    • Familiarity with event-driven architecture at scale
  • Languages, APIs and Databases

    • RESTful API design -versioning, security, OpenAPI specification
    • WebSockets — real-time bidirectional communication.
    • mTLS & Certificate Trust - mutual TLS configuration, x509 certificate lifecycle, PKI integration, client identity verification
    • Databases - MongoDB: Core operations - CRUD, aggregation pipeline, indexing strategies, Schema design, Query optimization.
  • Structured Logging & Observability
    • Open Telemetry - instrumentation code for distributed traces, metrics, and logs using the OTel SDK.
    • New Relic - APM integration, custom dashboards, alert policy configuration, service maps for cloud-native workloads
    • OpenSearch - structured log ingestion, familiarity with OpenSearch Dashboards for observability workflows
  • Cloud-Native Development - AWS & Kubernetes
    • AWS - EKS, EC2, S3, IAM, EMR, VPC, Security Groups, KMS, CloudWatch
    • Kubernetes - Service Mesh (Istio), Container Network Interface (CNI), eBPF, Secrets, RBAC, network policies, Pod Security Standards, Helm
  • Network Security
    • Familiarity with basic Networking Security Concepts - OSI & TCP/IP Model, Firewall & Traffic Control
    • Familiarity with firewall policy lifecycle — creation, review, audit, and automated compliance checks
    • Familiarity with SD-WAN and (IPSec/IKEv2/WireGuard) VPN topologies.
Candidate Profile
  • Strong problem-solving skills with the ability to quickly troubleshoot and resolve issues in production environments
  • Self-motivated, well-organized, and an effective team player in a globally distributed setup
  • Excellent written and verbal communication skills — able to articulate technical decisions clearly to peers and stakeholders
