Software Architect (f/m/d)

Galaxus, Switzerland’s top e-commerce platform with 3,000+ team members, is expanding fast. Team Empire builds the Data & ML Platform powering analytics and ML use-cases. We’re looking for a hands-on Software Architect to shape technical vision, drive trade-offs, and help engineers deliver at scale. Act galactic. Be you.

What you move

• Own and drive the system design vision for our Data Platform & ML Platform, and align it with the broader technical strategy.
• Define and clarify stable interfaces with other teams (e.g., dataset/data product contracts, APIs, event/stream contracts, feature definitions).
• Lead initiatives smoothly— acting as solution architect or enabling another engineers on that role.
• Ensure our technical decisions are consistent across solutions (security patterns, IAM, observability, CI/CD, data quality, governance).
• Continuously reduce technical debt and guide incremental refactoring of legacy parts.
• Review and challenge designs: ask probing questions, surface assumptions, and help reduce complex concepts to clear building blocks and simple interfaces.
• Drive non-functional improvements: scalability, reliability, performance, cost efficiency, and security.
• Collaborate closely with our Domain Architect, and partner stakeholders (e.g., Data Architect, Data Protection Officer) to ensure the platform supports compliance and federated governance.

What you will bring

• At least 2-3 years: Software Architect
• Completed degree (university / university of applied science / higher technical college)
• English (Fluent)
• Higher specialized education in the field of Computer Science (ETH/UNI/FH).
• Hands-on experience with an enjoyment of coding.
• A strong track record in designing and delivering platform solutions supporting distributed systems built by many different teams.
• Solid platform/DevOps engineering skills: cloud technologies (ideally GCP and Azure), CI/CD, automation, Docker containers, and orchestration (Kubernetes). Infrastructure-as-code (e.g., Terraform) is a plus.
• Strong understanding of data platform concepts such as orchestration and processing (e.g., Airflow, Dagster), data warehouses (BigQuery), and ETL/ELT practices.
• Familiarity with streaming/event-driven systems (e.g., Kafka).
• At least 5 years of professional experience in Python programming.
• Professional experience in C# is a strong plus.
• Background in Data Science or ML Engineering is a plus - you understand the pain points of training, deploying, and operating ML models at scale.
• Great communication skills in English; German is a plus.
