About the Role: SecurityScorecard is hiring a Principal Software Architect to lead the system design of our data platform. Rating 12 million companies continuously means ingesting internet-scale measurement data, processing it across streaming, microbatch, and batch paths, storing it so it stays queryable and affordable as it grows, and serving analytics fast enough that customers can explore their own risk in real time. The data is not a byproduct of our product. It is the product. That also raises the stakes on correctness. We publish a number about other companies, they dispute it, and underwriters price against it. A quiet data quality regression here doesn't produce a stale dashboard, it moves someone's score. Quality, contracts, and lineage are therefore architecture problems on this platform, not administrative ones. This is an individual contributor role reporting to the Chief Architect, alongside a Principal Architect focused on AI and agentic systems and a Principal Front-end Architect, and partnering closely with engineering leadership, Product, and Data Science. We're looking for someone who is opinionated about data architecture and persuasive about it: an architect whose designs get adopted because the reasoning is visible, not because they carry a title. Like the rest of our architecture function, you'll prototype to prove out decisions rather than implement full solutions, and you'll set direction through Technical Design Reviews (TDRs), and standards. You will lead the data domain, and you'll bring enough general distributed systems judgment to review designs across the wider platform.
