Instant Background Checks for Businesses. Backed by Y Combinator.
About the role
We’re looking for a senior engineer to support our scale. You’ll strengthen the infrastructure behind a live, revenue-generating product as we support larger customers, higher usage, and more demanding enterprise requirements: AWS, ECS/Fargate, CloudFormation, CI/CD, release management, observability, and reliability.
What they're looking for
- Professional software engineering experience building, shipping, and maintaining production systems. We care more about demonstrated ownership and judgment than years of experience, but this is not an entry-level role
- Ideally, experience at a fast-growing startup or small engineering team where you had to ship quickly, operate with ambiguity, and own work beyond a narrow job description
- Strong in Python, Django, and PostgreSQL
- Comfortable owning production AWS infrastructure end-to-end, from deployment configuration and permissions to reliability, scaling, observability, and cost management
- Comfortable with React: you don't need to be a frontend specialist, but you can build and modify UI when needed
- Proficient with AI-assisted development tools such as Claude Code, Cursor, Copilot, or similar tools. You use them regularly and they make you measurably faster

TrueBiz is a YC-backed merchant risk intelligence platform. We deliver 250+ risk signals on any business in under 30 seconds via API.
Our customers include some of the largest payment networks, fintechs, banks, and merchant services companies in the world. We help risk and underwriting teams understand who a merchant is, what they do, and whether their online presence suggests fraud, compliance, or business model risk.
We are a lean, profitable team building critical infrastructure for the payments ecosystem.
We use AI heavily, both inside the product and in how we build it. Our product uses LLMs as part of broader Python-driven workflows for analyzing businesses, websites, online presence, and risk signals. Our engineering team uses AI-assisted development tools aggressively to write, review, debug, refactor, and reason about code. We do not think of ourselves as an “AI wrapper” company, but we do expect engineers to have embraced modern AI tools and to use them with strong production judgment.
