📝Job Description :
As a 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.

Key challenges you will find working at MyTraffic:

• Building robust RAG pipelines: Designing systems that accurately retrieve data from our massive datasets to provide the LLM with the right context, avoiding hallucinations.
• Optimizing 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.
• Picking 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.
• Define and drive the best software development/engineering and operational practices for the team

🤝 About our stack :

At MyTraffic, we are convinced that mastering a particular framework or programming language is not the most important skill, as it can be learned. We are looking for candidates with an eye for detail, who seek to understand things in depth, and who challenge product issues.

However, you will be required to work on an existing stack, composed of:

• React and TypeScript for the frontend
• FastAPI (Python) for the backend
• LLM frameworks and tools (e.g., OpenAI/Anthropic APIs, LangChain, etc.)
• PostgreSQL, PostGIS and BigQuery for our databases
• AWS and GCP environment for managing data entering the product (data calculation is managed by Data Engineers)

🫵 About you :

• At least 1-2 years experience in a Software Engineer role and a Computer Science or related degree.
• A strong interest in, or hands-on experience with, Generative AI, LLMs, and RAG architectures.
• Hands-on experience working with architectures that take into account databases and applications using big chunks of data. Someone who can understand new problems, design technical solutions, and lead the implementation of the project.
• An analytical mindset. You are able to split problems into sizable components that are extendable and adaptable to future complications or modifications of the requirements.
• Deep 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.
• Mentor skills to help junior software developers on design patterns, development best practices, and DevOps trade-offs.
• Fluent in english

🎁 What we offer :

Joining our scale-up means:

• Attractive Salary : Around 30K€
• Dynamic Work Environment: Our department is a hub of innovation, testing new technologies and exploring new verticals.
• High Impact: The quality of our analyses is recognized by major market players, and our solutions have a significant impact on our clients.
• Cross-functional Collaboration: You will be the link between various MyTraffic teams throughout project timelines, ensuring comprehensive and effective solutions.
