Staff Backend Engineer - Enterprise Data Platform

About the role

An early-stage ECG SaaS company that unifies fragmented multi-tier supplier data into a single, audit-ready source of truth is hiring a Staff Backend Engineer. The role is hands-on and builder-first, with no people management: you will work alongside the Engineering Lead to turn a functional MVP into a resilient, high-throughput enterprise data hub that can scale 50x. The company is also setting up isolated European cloud regions to serve growing enterprise demand.

Key responsibilities

• Design and champion the technical vision moving the platform from early-stage cloud functions to an event-driven, containerised service architecture.
• Define canonical data contracts and schemas for hierarchical BOMs, supplier entities, material properties and compliance obligations.
• Build resilient ingestion pipelines that extract, transform and standardise structured and unstructured inputs from APIs, flat files, document extractions and legacy ERP/PLM feeds.
• Implement isolated regional deployments (US and EU data residency) with tenant isolation, zero-trust boundaries and SOC 2 / ISO 27001 readiness.
• Set up schema migration, zero-downtime versioning and dead-letter reprocessing to prevent data loss during tenant migrations.
• Work with ML specialists on pipelines for model training data, feature evaluation and inference monitoring.
• Lead architectural discussions, data security workshops and technical due diligence with prospective enterprise IT and security stakeholders.

Required profile

• 8+ years of senior-to-staff backend engineering, architecting data-heavy, multi-tenant B2B SaaS platforms.
• Experience scaling early architecture from seed to scale in a fast-moving startup or complex data-intensive domain such as supply chain, logistics, fintech or energy.

Required skills

• Advanced PostgreSQL: schema design, performance tuning, zero-downtime migrations and Row-Level Security.
• TypeScript and Node.js in structured frameworks such as NestJS.
• AWS (ECS/Fargate, event queues, serverless, IAM/OIDC) provisioned with Terraform or AWS CDK.
• Idempotent, asynchronous data pipelines, message brokers/queues and schema validation.
• Working knowledge of hardening cloud systems for SOC 2 Type II or ISO 27001 audits.
