Job description

Overview

We’re looking for an experienced Senior Data Engineer to join our growing data team at Inven. You’ll be part of a high-energy product and engineering group where ownership is real and impact is immediate.

At Inven, AI isn’t an add-on — it’s the foundation of how we deliver value to our users. As a Data Engineer, you’ll work on complex, data-heavy features, shaping what a great AI-first product looks like. From designing scalable infrastructure to tackling novel data challenges, you’ll be at the core of our innovation.

What You’ll Do

• Design and maintain robust, scalable data pipelines.
• Build infrastructure to power AI-driven product features.
• Collaborate with product and ML teams to turn raw data into insights.
• Solve complex problems in data quality, retrieval, and transformation.
• Shape the technical direction of a rapidly growing startup.

What We’re Looking For

We want someone who thrives in a startup environment: ambitious, curious, and eager to push boundaries. Specifically, you bring:

• Proven track record in building and scaling data infrastructure and data products.
• Strong technical skills: high proficiency in Python and SQL.
• Hands-on experience with modern, cloud-based data infrastructure (AWS preferred, but Azure/GCP also valuable).
• Familiarity with data orchestration tools (Flyte, Airflow, Prefect, etc.) and infrastructure-as-code (Terraform, Kubernetes).
• Experience with data processing frameworks (Spark, Snowflake, Postgres).
• Bonus: Past work on entity resolution, unstructured-to-structured data extraction, document retrieval, ranking, or clustering.
• Fluency in English or Finnish.

What We Offer

• Competitive salary + equity: you’ll own a piece of the company.
• True ownership & flexibility: do what sparks your interest and move between teams
• A focus on building: minimal bureaucracy, no redundant overhead, no sitting in meetings all day
• Impact at scale: your work will directly shape a product used by investors globally
• AI-first culture: front-row seat to building a truly AI-native product.
• Great people & community: a central Helsinki office, regular team activities (we try new sports and activities together), and an extraordinary team spirit.

The Process

• 30min phone screen with our recruiter
• 1h (technical) interview with some members from our dev team
