Qualifications - 5–8+ years of professional software development experience building production-grade applications. - Strong experience in full stack / end-to-end development. - Solid expertise in C# and modern .NET development (.NET 6/7/8 preferred). - Strong frontend development experience with React. - Experience building and consuming RESTful APIs and microservices. - Good understanding of distributed systems and event-driven architectures. - Hands-on experience with messaging technologies such as Kafka, RabbitMQ, or Azure Service Bus is a plus. - Experience working with SQL databases, query optimization, and performance tuning. - Familiarity with cloud platforms such as Azure or AWS. - Experience with CI/CD pipelines and modern DevOps practices. - Exposure to AI-related technologies such as OpenAI, Claude, Copilot, LangChain, or prompt engineering is highly desirable. - Experience integrating AI capabilities into applications is a strong plus. - Strong understanding of software engineering best practices including Clean Code, testing strategies, and scalable architecture design. - Ability to work independently in fast-paced and collaborative environments. - Advanced English communication skills (written and verbal). Requirements - Design, develop, and maintain scalable backend services and APIs using C# and .NET. - Build and enhance modern frontend applications using React. - Develop end-to-end full stack solutions with focus on performance, scalability, and maintainability. - Collaborate with cross-functional teams to define technical solutions and deliver high-quality software. - Participate in architecture discussions, code reviews, and technical decision-making processes. - Optimize application and database performance through troubleshooting and tuning. - Integrate cloud-native and AI-powered capabilities into existing and new applications. - Work with modern development tools, CI/CD pipelines, and agile methodologies. - Contribute to modernization and continuous improvement initiatives across the engineering organization. - Ensure code quality, reliability, security, and scalability through engineering best practices. Benefits - Stock options 📈 - Remote work options 🏠 - Flexible working hours 🕜 - Benefits above the law

• The Analytics Toolbox framework. Shape how spatial analytics is packaged, versioned, and pushed down into partner engines — and what it looks like when the consumer is an LLM agent, not a UI. • Partner-engine SQL strategy. Every engine has its own dialect, optimizer, and idioms. You'll set the direction for how CARTO writes once and runs everywhere, without losing warehouse-native performance. • The Iceberg / open-format play. CARTO organized the 2021 meeting with BigQuery, Snowflake, Redshift, and Oracle that catalyzed GeoParquet, and authored RaQuet for raster in Parquet. Iceberg is next. You'll define what spatial-first Iceberg looks like — for CARTO and for the ecosystem. • Community and standards presence. This work happens in the open. OGC working groups, the Cloud Native Geospatial community, FOSS4G, conference talks, RFCs. You'll represent CARTO externally and help move the standards forward. • AI as a native execution surface. Agentic GIS is where we're going. The Toolbox isn't just a SQL library — it's the substrate AI agents call into. You'll help define that interface.
