Senior Software Engineer Python/GIS - Location Intelligence

**Senior Software Engineer Python/GIS - Location Intelligence** **Location: Warszawa, Fabryka Norblina** **Company: Allegro sp. z o.o.** ## ### **About the Team** The Location Intelligence Engineering team is part of the Delivery Experience (DEX) area at Allegro. We have recently extended our focus from internal supporting tools to driving the core technical engine behind our logistics support. Through the Delivery Optimization Engine (DOE), we solve complex, large-scale problems in routing, automated parcel sequencing, and dynamic courier zone balancing. Our high-performance services directly compress fleet size and maximize vehicle utilization across our rapidly growing logistics network in Poland and abroad. As a Senior Software Engineer specializing in Python and routing algorithms, you will design and scale the high-throughput services that power our first and last-mile operations. By leveraging network analysis and spatial optimization, you will help us build the next generation of Allegro's Delivery Optimization Engine and directly redefine our logistics efficiency. ### **We are looking for people who:** * 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). * Are 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. * Have a positive attitude, excellent teamwork skills, and a higher technical education (Computer Science or related fields). ## ### **Why is it worth working with us?** * Real-World Impact: You will build the algorithms and data foundations that directly optimize routes and fleet utilization for first and last-mile operations. * Modern 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). * Stability & Integration: We offer long-term stability and deep team integration via an Umowa o Pracę (UoP) contract within a highly collaborative engineering environment. * Our Current Technology Stack Includes: * 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. ## ### **What's in it for you:** * Flexible working hours in the hybrid model (4 days in the office / 1 day remote) - working hours start between 7:00 a.m. and 10:00 a.m. We also have 30 days of occasional remote work. * Long term discretionary incentive plan based on Allegro.eu shares (restricted stock units). * Annual bonus based on your annual performance and company results. * Well-located offices (with e.g. fully equipped kitchens, bicycle parking, terraces full of greenery) and excellent work tools (e.g., raised desks, ergonomic chairs, interactive conference rooms). * A 16" or 14" MacBook Pro or corresponding Dell with Windows (if you don't like Macs) and all the necessary accessories. * A wide selection of fringe benefits in a cafeteria plan - you choose what you like (e.g., medical, sports or lunch packages, insurance, purchase vouchers). * English classes that we pay for related to the specific nature of your job. * A training budget, inter-team tourism ([see more here](https://blog.allegro.tech/2019/09/team-tourism-at-allegro.html)), hackathons, and an internal learning platform where you will find multiple trainings. * An additional day off for volunteering, which you can use alone, with a team, or with a larger group of people connected by a common goal. * Social events for Allegro people - Spin Kilometers, Family Day, Fat Thursday, Advent of Code, and many other occasions we enjoy. And that's just the beginning! You can read more about the b
