Senior Software Engineer, Feature Engineering Platform

About the role

Wolt is building a new Feature Engineering Platform that will be the entry point to machine learning development at global scale. As a Software Engineer on this team you will help build a seamless experience for ML practitioners, from experimentation and exploration through to deployment and monitoring. The platform supports both high-level declarative workflows and lower-level imperative APIs, integrated into the environments users already work in, such as notebooks and internal sandboxes.

Key responsibilities

• Build and evolve APIs, SDKs and platform integrations that power feature engineering workflows.
• Help shape user-facing tools that make the platform approachable for all skill levels.
• Collaborate across the ML lifecycle, from data ingestion to feature serving, and integrate tightly with the central Data Control Plane.
• Contribute to platform reliability, testing, observability and operational excellence.

Required profile

• Solid engineering background, ideally in platform, data or ML-adjacent teams.
• Comfortable working with backend systems and APIs.
• Experience with ML tooling or data pipelines is a plus.
• Curious, collaborative and empathetic towards users, interested in building abstractions that reduce friction.

Required skills

• Backend systems and APIs.
• Ideally some exposure to distributed compute such as Spark or Flink.

What we offer

• Pay range of EUR 7,102 to EUR 8,878, depending on skills, experience, qualifications, location and market conditions.
• Possibility of an equity award grant of restricted stock units at start and during the annual pay review cycle.
