Senior Backend & Platform Security Engineer (Node.js)

SustainGRC is an AI-native Sustainability & GRC platform, unifying sustainability, audit, risk, and governance into a single enterprise intelligence layer. We help global organisations turn fragmented ESG, risk, and compliance data into trusted, decision-grade insights.

We are hiring a Senior Backend & Platform Security Engineer (Node.js) to take technical ownership of critical backend services, platform security, and production reliability.

This is not a junior or feature-only backend role.

You will work on core platform services, security architecture, and deployment pipelines that support enterprise-grade, regulated workloads.

This role is suited for engineers who:

• Have owned backend systems in production
• Think in terms of platforms, not endpoints
• Care deeply about security, reliability, and operational excellence
  

• Design, build, and own scalable backend services using Node.js (TypeScript)
• Architect and maintain REST APIs and microservices used across the platform
• Take end-to-end ownership: design → implementation → deployment → monitoring
• Identify architectural risks, edge cases, and scalability concerns early
• Enforce clean architecture, SOLID principles, and long-term maintainability

• Design and maintain authentication & authorisation systems (JWT, OAuth2, RBAC)
• Implement secure API patterns, permission models, and data access controls
• Collaborate on security best practices for enterprise and regulated environments
• Ensure secure integrations with third-party services and internal components

• Design and optimise PostgreSQL schemas, queries, and indexing
• Use Redis for caching, queues, and performance optimisation
• Integrate external services (APIs, messaging, email) with reliability and traceability
• Support real-time features where applicable (e.g. Socket.io)
• Work with object storage (S3-compatible)

• Contribute to Docker-based containerisation and environment parity
• Improve and maintain CI/CD pipelines (GitHub Actions or similar)
• Support cloud deployments with a GCP-first mindset
• (GKE, Cloud Run, Cloud SQL, IAM, Cloud Storage)
• Promote best practices in monitoring, logging, alerting, and error tracking
• Help ensure safe deployments, high availability, and predictable releases
  

• 5+ years of professional backend engineering experience
• Strong expertise in Node.js, TypeScript
• Production experience with Express, Fastify, or NestJS
• Strong SQL skills and deep experience with PostgreSQL
• Hands-on experience with Redis
• Understanding of microservices and distributed systems
• Experience with Docker and CI/CD pipelines
• Strong grasp of API security, authentication, and RBAC
• Experience owning systems in production (not just implementing tickets)
• Comfortable making architectural decisions and trade-offs

• Hands-on experience with Google Cloud Platform
• Exposure to Kubernetes (GKE) or managed container platforms
• Experience with observability tools (Prometheus, Grafana, Sentry, GCP Monitoring)
• Background in enterprise SaaS, compliance, or regulated platforms
  

• Work on a global, AI-native enterprise platform
• Fully remote role
• Competitive contract-based compensation and/or equity
• High ownership, low bureaucracy engineering culture
• Opportunity to grow into platform or technical leadership roles
  

At SustainGRC, you’ll help build the intelligence layer behind global sustainability and governance — powering better decisions for enterprises worldwide.

Apply only if you have senior-level backend experience and have worked on production platforms.
