TrueBiz (YC S22) – Senior Software Engineer – Remote (US) – Full-Time

TrueBiz (YC S22) is an API that tells financial institutions whether a business is real, what it actually does, and whether it’s risky — in seconds.

Today, this process is still manual: underwriters spend 20–30 minutes Googling websites, reviews, and social profiles to make a decision. We replace that with an API that analyzes thousands of signals across the internet and returns a decision in ~30 seconds.

We’re already live with companies like Visa, Mercury, and Lightspeed, and processing millions of requests as part of critical payment and onboarding flows.

We’re a lean, high ownership team that built a profitable, fast growing model that doesn’t need more VC

We’re hiring a Senior Engineer to help us scale the system and expand the product.

What you’ll work on:

* Scaling high-throughput, low-latency systems (AWS ECS/Fargate, RDS, async pipelines)
* Designing systems that ingest and reason over messy, real-world web data
* Building product features end-to-end (Python/Django + React)
* Improving reliability, observability, and performance for enterprise workloads
* Shaping how AI agents evaluate business risk (not just calling APIs)

What we’re looking for:

* Strong backend experience (Python/Postgres)
* Experience running production systems on AWS
* Comfortable owning systems end-to-end (design → deploy → debug)
* Pragmatic, high-ownership builder

Remote (US)
