MyTraffic teams throughout project timelines, ensuring comprehensive and effective solutions. /p h3 Job Description /h3 pAs a senior Software Engineer, you join the team responsible for building and maintaining “Gini”, the best AI assistant for geospatial analytics (released in February 2026!), from the most visual components to the database structure, RAG (Retrieval-Augmented Generation) and pipelines to ingest data. The team is composed of several Backend and Frontend Engineers, 2 PMs, and a designer, working very closely with DevOps Engineers, Data Engineers, and Data Scientists. We conduct extensive integration tests. We love going the extra mile and looking for continuous improvements as we believe great isn’t good enough. You will face many challenging but interesting problems, pull requests, and technical challenges all while working with super friendly colleagues. Your daily work will include thinking, defining, and implementing technical solutions that will allow Gini to seamlessly interact with our unique and proprietary datasets to answer complex customer queries intelligently and securely. /p h3Key challenges you will find working at MyTraffic /h3 ul liBuilding robust RAG pipelines: Designing systems that accurately retrieve data from our massive datasets to provide the LLM with the right context, avoiding hallucinations. /li liOptimizing for scale and speed: Designing for datasets one order of magnitude higher than most companies, while keeping LLM response times low and handling streaming text generation for a seamless user experience. /li liPicking the right tool for new problems: Running predictions at scale, generating user-time OLAP insights, and integrating cutting‑edge AI frameworks into a stable production environment. /li liDefine and drive the best software development/engineering and operational practices for the team /li /ul h3About our stack /h3 pAt MyTraffic, we are convinced that mastering a particular framework or programming language is not the most important skill, as it can be learned.

Someone who can understand new problems, design technical solutions, and lead the implementation of the project. /li liAn analytical mindset. You are able to split problems into sizable components that are extendable and adaptable to future complications or modifications of the requirements. /li liDeep experience with SQL and databases. We rely on our databases for a lot of the heavy lifting. If you haven’t used our specific databases before, don’t worry as long as you have a deep understanding of databases. How to design a proper schema, being able to understand a query plan, and knowing when to use window functions, are all things you will need to be great at. /li liMentor skills to help junior software developers on design patterns, development best practices, and DevOps trade‑offs. /li liFluent in English /li liIf you’re the type of person that is constantly reading about new trends to see what’s going on out there and how you can incorporate new technologies into your current project when there are good reasons for it, then we want to hear from you. /li liIf you don’t meet all the criteria, don’t worry.
