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.
Job Responsibility
Own and evolve our AWS infrastructure: ECS/Fargate, RDS, ElastiCache, S3
Build and maintain CI/CD pipelines, deployment automation, and release management processes
Improve observability, alerting, and incident response as we scale
Ship full-stack product features in Python/Django and React
Improve the reliability, latency, and debuggability of workflows that depend on external APIs, web data, and LLM calls
Use AI-assisted development tools to move faster on implementation, debugging, test generation, refactoring, documentation, and code review
Work on both new systems and unglamorous but important fixes: bugs, edge cases, small optimizations, operational cleanup, and customer-impacting issues
Collaborate with engineering, sales, and customer success to support enterprise customers
Requirements
Professional software engineering experience building, shipping, and maintaining production systems
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
Strong judgment when working with AI-generated code: you know how to review it, test it, constrain it, and keep it from making the codebase worse
Git: clean branches, good commit hygiene, comfortable with rebases and release workflows
Bias toward action. You default to shipping over deliberating, but you know when infrastructure decisions need to be right the first time
Comfortable in a small team where the work ranges from architecture decisions to customer-impacting bugs
Comfortable with some customer context. This is not a sales role, but you should care about how engineering decisions affect real enterprise users
Nice to have
Experience with ECS/Fargate, Terraform or other IaC tools, CI/CD, and production deployment workflows
Experience with observability tools such as Datadog, OpenTelemetry, CloudWatch, Grafana, or similar
Experience with API Gateway or production API infrastructure
Experience with queue-based or async workflow systems such as Celery
Experience operating systems that depend on third-party APIs, scraping, external data vendors, or LLM APIs
Experience with payments, fintech, fraud, underwriting, compliance, or risk systems
