Senior/Lead Software Engineer

We are looking for an AI-native software engineer with a focus on backend development to join our Suppliers team in Helsinki. Depending on your experience, we'll bring you in as a Senior or a Lead Software Engineer.

Being honest, we haven't got this all figured out yet. Agentic development at Sievo is still in an exploration phase: engineers and teams across the company are trying things, seeing what works, and management backs that exploration rather than dictating one way to do it. Some parts of our SDLC are already fully agent-driven; a lot of it still isn't. Where we want to get to is agentic development as the default: agents involved from spec through to production, with checks built in along the way. We're early in that shift, and in this role you will help us realize this ambition.

This role combines software engineering, quality engineering, solution design and end-to-end delivery through agentic AI systems, specification-driven development, and modern cloud-native practices.

About the team

The Suppliers team is the architectural backbone of Sievo's data layer. We are on a mission to build the "Single Source of Truth" for global procurement intelligence, transforming fragmented, "messy" supplier data into a reliable foundation for the world's largest enterprises.

Every month, we turn millions of raw vendors records into a clean, trustworthy view of who a company's suppliers really are. Supplier parenting, i.e. matching vendor-level records to their parent companies, is the hardest and most visible part of that, but the domain is broader: data quality, matching at scale, enrichment, and the services other teams build on top.

In this role, your architectural decisions become the platform's defaults for teams building on top of Suppliers. You get to shape how we process spend equal to 2% of global GDP - a challenge that won't let you get bored!

Teams at Sievo own their services end to end i.e. design, build, deploy and run in production. That ownership
