Resumo da oferta

Descrial is seeking a Back-End Engineer for its UK core team in central London. You will build multi-tenant services and the integration layer between Java/Spring and Python AI services, emphasising security, observability, and reliability.

You will work with AWS, CI/CD, and OpenTelemetry, contributing to production SaaS at scale. The role offers collaboration with senior leadership and a tight-knit team in the London office.

Qualificações

• 5+ years of backend engineering in production SaaS or platform environments.
• Real multi-tenant or enterprise-grade system experience: isolation, permissions, auditability.
• Strong Python (FastAPI or comparable) and solid SQL/PostgreSQL; ability to work at Java/Spring service boundaries.
• AWS production experience; Git, CI/CD, Linux as second nature.
• You build with AI coding tools daily (Cursor, Claude Code or comparable) and have a considered view of where they help and where they do not.

Responsabilidades

• Design and ship REST and async services in Python 3.11+ / FastAPI with PostgreSQL persistence.
• Implement multi-tenant patterns: isolation, tenant context, and RBAC.
• Own API contracts between core services and AI services; version and evolve them safely.
• Write comprehensive unit and integration tests (pytest / pytest-asyncio).
• Build observability: OpenTelemetry traces, structured logs, metrics, alerts, and cost-aware AI model calls.
• Enforce security fundamentals: authN/authZ, secrets, input validation, and audit trails.
• Deploy and operate services on AWS (EKS/ECS, RDS, S3) via Jenkins CI/CD.
