Senior Backend Engineer | Routing Team

About the Team

The Routing Team is the engineering core of Instabee, tasked with solving one of logistics' greatest challenges: the "Traveling Salesman Problem" at scale. We build the systems that plan and optimize thousands of last-mile delivery routes in real time. As a Senior Backend Engineer, you’ll join a high-impact squad of three backend developers, a frontend specialist, and a Staff Engineer. This is a role for an engineer who wants to see their code have an immediate, measurable impact on global distribution costs and delivery accuracy.

Technical Environment

Our ecosystem is built for high-concurrency and reliability. While we are primarily a Golang shop, we value engineers who can navigate polyglot environments and lead the modernization of existing systems.

🐹 Languages: Golang, (Primary), with legacy components in Java and Node.js.

🗄️ Data & Storage: PostgreSQL, MongoDB.

☁️ Infrastructure: GCP, Kubernetes (Helm), Terraform.

🔁 CI/CD & Observability: GitHub Actions, Grafana.

Core Responsibilities

You will take full ownership of the backend lifecycle, from initial design and requirement gathering to production delivery. A key part of your mission will be evolving our legacy services into modern, high-performance architectures that ensure long-term scalability. We expect you to write clean, maintainable code that sets the standard for the rest of the engineering organization.

Beyond the IDE, you will foster a strong engineering culture through technical mentorship and rigorous code reviews. You’ll act as a strategic partner to Product Managers, refining technical solutions that move the needle on our key KPIs. You will also play a critical role in system resilience, leading incident management and root-cause analysis to ensure our production environment remains world-class.
