Job summary

aspaara AG is a fast-growing B2B SaaS company in Switzerland seeking a Senior Operations Research Engineer (Applied AI, B2B SaaS) to advance AI capabilities for automotive aftersales operations. You will design AI models, optimize scheduling, and build end-to-end systems that learn from real data.

The role emphasizes data-driven decision making, ML model deployment, and collaboration with a strong technical team to deliver impact across multiple European markets.

Qualifications

• Master’s or PhD in Computer Science, Mathematics, Physics or a related field.
• Several years of experience in machine learning, particularly with tabular data and time series.
• Strong knowledge of at least one deep learning framework (PyTorch is preferred).
• Experience designing optimisation algorithms and heuristics for complex, constrained problems.
• Proficient in Python and the data science ecosystem (pandas, scikit-learn).
• Experience with ML experiment tracking and model deployment (MLflow, Docker, Kubernetes).
• A self-driven, solution-oriented mindset and business problem understanding.
• Fluent in English.

Responsibilities

• Design and deploy AI models for prediction and decision-making on domain-specific operational data.
• Advance and extend scheduling and resource optimisation, including multi-objective optimisation, constraint handling, and stable re-planning.
• Build end-to-end models that learn from real operational data and improve planning accuracy over time.
• Own the full AI lifecycle: data analysis, feature engineering, model development, evaluation, and monitoring.

Job description

About the Company

We are a fast-growing B2B SaaS company building an AI-driven platform to transform automotive aftersales operations.

Our product helps bodyshops, dealer groups, and multi-site operators optimize workflows, improve efficiency, and make better decisions through data. Using digital twin technology and real-time optimization, we uncover operational improvements that are often hidden in day-to-day processes. In practice, this means helping workshops plan work more accurately, assign jobs to the right people, and predict when work will be completed. At the core of our platform is our AI: machine learning models and optimization algorithms that power intelligent predictions and decisions in complex operational environments.

With customers across multiple European markets and strong early traction, we are now looking to hire a Senior Operations Research Engineer (Applied AI, B2B SaaS) to further strengthen our product and AI capabilities.

Do you want to help shape our award-winning artificial intelligence of tomorrow, which is already improving the working lives of thousands of people across eight European countries today? Become an integral part of our established yet dynamic startup team.

Tasks

• Design and deploy AI models for prediction and decision-making on domain-specific operational data
• Advance and extend scheduling and resource optimisation, including multi-objective optimisation, constraint handling, and stable re-planning
• Build end-to-end models that learn from real operational data and improve planning accuracy over time
• Own the full AI lifecycle: data analysis, feature engineering, model development, evaluation, and monitoringTranslate business problems into formal models and measurable outcomes

Examples of What You’ll Build

• Capacity planning algorithms that account for skills, time buffers, cool-down periods, and space constraints
• Intelligent job-to-talent matching with dynamic weighting for in-progress vs. new projects
• Automated project creation from structured and unstructured operational inputs (e.g. PDFs, free text)

Requirements

• Master’s or PhD in Computer Science, Mathematics, Physics or a related field
• Several years of experience in machine learning, particularly with tabular data and time series
• Strong knowledge of at least one deep learning framework (PyTorch is preferred)
• Experience designing optimisation algorithms and heuristics for complex, constrained problems
• Proficient in Python and the data science ecosystem (e.g. pandas, scikit-learn)
• Experience with ML experiment tracking and model deployment (e.g. MLflow, Docker, Kubernetes)
• A self-driven, solution-oriented mindset: you don’t just build models, you understand the business problem behind them
• Fluent in English

Nice to Have

Beyond our core artificial intelligence, we are exploring additional AI capabilities that will flow into the product over time. Experience in this area is not required, but a plus:

• Experience with LLMs or agentic systems (e.g. RAG, information extraction from unstructured data, API-based workflows)

Benefits

• Creative freedom in a young, technically ambitious team
• Direct impact of your work on the product and our customers
• A modern tech stack and a culture that encourages experimentation
• A real-world, domain-rich problem space, not another generic SaaS
• End-to-end ownership of AI features, from data exploration to production deployment

If you want to work on meaningful AI problems, take ownership, and see your work used in the real world, we'd love to hear from you.
