Duranta | Full-Time | Staff backend engineers | Location: Seattle, WA or NYC | On-site

Company: we're a small startup (pre Series A) building a business-in-a-box solution for landscaping companies, initially targeting the US. It's a huge market with more than 700000 companies in the US alone but with very little good software. We're looking for a very experienced backend engineer (senior/staff level) capable of taking ownership and leading the development of entire systems.

We keep our infrastructure as simple as possible, so the entire backend is in Golang with Postgres+S3 as the data storage layer. And a bit of Terraform for the infrastructure.

We're NOT a standard "AI startup" doing LLM wrappers, but we do have our own computer vision AI that we use to produce models from satellite imagery. So if you're interested in working on unusual AI pipelines, we have plenty of work there too.

Our frontend is a React.Native app, and we're working towards having full feature-parity inside a regular webapp.

Experience:

* Go backend experience

* A lot of experience with distributed systems

* Designing robust APIs (we're using ConnectRPC)

* Ideally experience with offline apps and database synchronization

* The usual: infrastructure-as-code, Docker, Github actions, OpenTelemetry, etc.

Salary: $170-$210k and equity
