Senior Software Engineer - AI Supply Chain Platform

About the role

A Senior Software Engineer builds and owns full-stack features for an AI platform that modernizes procurement and distribution across defense, aerospace and industrial supply chains. The engineer takes ownership of customer-facing features end to end, from understanding the operational problem through implementation, testing, deployment and follow-up in production. The position is based in Warsaw, with relocation to the United States required within about six months of starting.

Key responsibilities

• Design, implement, test, deploy and operate full-stack product features.
• Build frontend experiences with TypeScript, JavaScript, React, Next.js or Svelte.
• Develop backend services and APIs with Node.js or Python.
• Design PostgreSQL schemas, write production SQL and improve query performance.
• Build integrations and data-ingestion workflows for fragmented operational systems, documents, APIs and business data.
• Translate customer and operational requirements into maintainable technical solutions.
• Own delivered features through production, including monitoring, debugging, incident resolution and iteration.
• Communicate technical proposals, delivery estimates, risks and trade-offs clearly to founders, deployment strategists and engineers.
• Maintain high standards for code quality, testing, security, reliability and long-term maintainability.
• Use AI coding tools to speed up development, validating generated code through review, tests and production safeguards.
• Contribute to a fast-moving product environment where engineers work with incomplete requirements and take responsibility for outcomes.

Required profile

• Professional experience building production software as a full-stack engineer.
• Experience owning features or systems from initial implementation through production operation.
• Ability to communicate technical decisions, delivery commitments, risks and trade-offs clearly.
• Evidence of independently building software beyond narrowly defined ticket work, such as a shipped side project, open-source contribution, hackathon project or zero-to-one product.
• Willingness to relocate from Warsaw to the United States within about six months of starting.
