Job description

Leica Geosystems is looking for a highly motivated and passionate Senior Software Engineer to strengthen our data-modelling platform team. Our data management SDK is a future-proof data-modelling framework – the platform technology that manages our domain data (data structure and persistence) in a common, reusable way across our product portfolio. Our vision is an end-to-end, automated round-trip of the data, from the Common Data Environment (CDE) through the domain models that power our digital reality platform.

You will help shape the C++ core of this platform – designing the domain models, containers and persistence mechanisms that many products build upon. We work test-driven, with strong quality gates, and we actively embrace AI as a first-class part of how modern software is engineered. If you love clean architecture, well-modelled data, and using the latest AI tooling to multiply your impact, we want to hear from you.

• Strong grasp of data modelling, data structures and persistence concepts, with applied experience of Domain-Driven Design (DDD).
• Hands-on, daily use of AI coding assistants (e.g. GitHub Copilot, ChatGPT / Claude) for code generation, refactoring, tests, debugging and documentation – with effective prompt engineering, a track record of raising productivity and quality, and critical evaluation of their output.
• Modern, test-driven development practices within an agile environment, and a habit of automating everything.
• Version control with Git (GitHub) and CI/CD experience (GitHub Actions or comparable).
• You express your opinion freely, challenge constructively, and align with agreed team decisions once a direction is chosen.
• Fluent in English (written & spoken); German is a plus.

NICE TO HAVE:

• Experience with GraphQL / REST, CQRS, federated data and distributed systems.
• Practical experience applying AI/ML techniques to data-modelling problems – e.g. schema inference, automated data mapping/validation, semantic enrichment or intelligent data transformation.
• Docker / containerised toolchains and static-analysis / quality gates (e.g. SonarQube).
• CMake, package management (e.g. Conan) and cross-platform development.
• Exposure to cloud-native development (AWS).
