Backend Software Engineer (Python) — Threat Intelligence & Security Platform

New York, NY (Hybrid)

Want your Python to protect one of the world's most critical financial platforms? A leading global financial-technology firm is hiring a backend engineer for its Threat Intelligence & Forensics team to modernize the systems that store, source, and correlate threat data across the enterprise. This is deep backend work — schema design, clean API interfaces, a company-wide IAM rollout, and a new client library that becomes the drop-in standard for security teams across the organization.

What you'll do

• Design database schemas and migrate to internally managed relational stores
• Build and evolve REST APIs and middleware
• Refactor services to consume clean APIs and shed direct DB coupling
• Ship a new IAM-aware client library used across multiple security teams
• Own testing (unit → e2e) and performance tuning under load

What you bring

• Strong Python (the core requirement)
• REST APIs, relational + NoSQL (PostgreSQL, MySQL, MongoDB)
• Linux + distributed systems, CI/CD, debugging, performance optimization
• Bonus: Redis, Solr/OpenSearch
