Python/Gis Developer

We are looking for support of Senior Software Engineer specializing in Python and routing algorithms. The specialist will be responsible for supporting the design and scaling of high-throughput services that power our first and last-mile operations. By leveraging network analysis and spatial optimization, the specialist will assist in building the next generation and directly enhancing our logistics efficiency.

Tech Stack: We are bypassing traditional, legacy GIS software in favor of cloud-native Python architectures, Big Data solutions, and modern routing APIs (e.g., Google, HERE, open-source routing engines).

Current Technology Stack used in Project:

• Backend & Routing: Python, Microservices, Open-source & Commercial Routing Engines.
• Data & Cloud: Google Cloud Platform (BigQuery, Dataflow, Composer/Airflow), SQL.
• Infrastructure: Kubernetes,Terraform, CI/CD pipelines.

Engineer engaged to deliver this order should:

• Have at least 4 years of commercial experience in backend software development using Python and SQL.
• Possess experience or a strong understanding of the logistics domain, network analysis, and routing (e.g., graph theory, road network modeling, Vehicle Routing Problems)
• Have experience with geospatial data concepts applied via code (e.g., H3/spatial indexing, clustering algorithms, PostGIS).
• Be familiar with cloud ecosystems (Google Cloud Platform preferred) and modern infrastructure tools (Kubernetes, Terraform, Airflow).
• Advocate for engineering excellence, including clean code, TDD, CI/CD, and a strong commitment to rigorous code reviews to maintain team architectural stability.
• Know how to design and scale a microservices-based architecture.
