TrashLab - Sr. Software Backend Engineer

What you'll do

* Own the infrastructure that keeps fleets running

* Design, build, and maintain backend services for real-time vehicle tracking, route optimization, billing, and dispatch — systems haulers depend on from first route to last invoice.

* Build for reliability and scale

* Own the reliability and observability of our platform. Set up monitoring, alerting, and on-call practices that give the team confidence to ship fast without breaking things.

* Design data systems that handle complexity

* Model and evolve our Postgres schema, manage migrations, and build integrations with third-party systems — billing providers, telematics APIs, and customer communications platforms.

* Shape backend architecture long-term

* Work closely with the founding team to define decisions that will compound over time. You'll have outsized influence on what we build and how.

* Strong backend fundamentals

* You've built and shipped production Node.js services. You understand API design, database performance, and distributed systems tradeoffs.

* Infrastructure experience

* You've managed cloud infrastructure — ideally on AWS or GCP — and are comfortable with containers (Docker), orchestration (Kubernetes), CI/CD pipelines, and defining infrastructure as code (Terraform).

* Ownership mindset

* You can take an ambiguous problem, scope it, and ship a solution without needing everything defined upfront.

* Comfort with operational software

* AI multi-agent expert

Interview Process
