About the role

  • Company Description We have an internet for money - but still can't tell real companies apart from fake ones.
  • While others focus on consumers, we separate real companies from synthetic ones.
  • With AI accelerating fraud rings and shell companies at global scale, distinguishing a legitimate business from a sophisticated fraudster is now one of the hardest problems in fintech.

Responsibilities

  • Build and ship production features across the platform: backend services, APIs, graph query layers, and customer-facing tools
  • Develop infrastructure that serves inference and network analysis results in real time with high accuracy and low latency
  • Build integrations with customer systems. Financial institutions have high reliability and auditability standards, and you'll own meeting them
  • 3+ years building production backend systems (we care more about skill and impact than years alone)
  • Strong coding ability - you write production-quality code, reason clearly about system design, and can move through a complex codebase quickly

Requirements

  • Experience with data-intensive systems - you've worked with large datasets, built pipelines, or operated services at meaningful scale
  • Comfort with ambiguity and fast iteration in an early-stage environment

Nice to have

  • Background in fintech, fraud detection, or identity systems
  • Experience with graph databases, entity resolution, or network analysis
  • Experience scaling infrastructure under real production load
  • Experience with ML model serving or inference infrastructure in production

Company info

  • We're a small, tight-knit, and highly technical team.
  • Our founders and early team members come from Waymo, Google, Meta, Brex, and Virtu Financial.
  • We value technical depth and curiosity, low ego, and fast execution.
  • We've partnered with investors who understand the plumbing of the global financial system.
  • We recently raised a round led by Nyca Partners, with participation from operators who built the modern fintech stack at Ramp, Plaid, and Brex.
  • Company Description
  • We have an internet for money - but still can't tell real companies apart from fake ones.
  • Cobalt ID is building the business identity infrastructure for the financial internet.
  • We're mapping 100M+ businesses and counting to expose hidden financial crime networks and ensure real businesses are never left out of the financial ecosystem.
  • Role Description
  • As a Senior Software Engineer, you'll be one of the early technical hires building the systems that power our platform.
  • You'll work across the stack, writing production code that powers graph-based network analysis, scaling infrastructure to serve API requests in seconds, and shipping features that directly impact how leading financial institutions catch fraud.
