Sii

Founded in 2006 and based in Poland, Sii Polska operates offices across the country alongside foreign branches in Sweden, Ukraine and India, with a workforce it describes as 7,500+ "Power People." The company works across sectors ranging from high tech and semiconductors, industrial manufacturing and telecommunications to retail and corporate banking, insurance, fintech, healthcare, life science, medical and diagnostics devices, automotive, aerospace and defense, rail, public utilities and energy, media, retail and e-commerce, fashion, consumer goods, and logistics.

Service lines span application development, systems integration, data engineering and pipelines, cloud architecture across AWS, Azure and GCP, security audits, penetration testing, vulnerability management, and ML model development. Alongside these sit enterprise platforms, digital IT infrastructure, service desk and user support, testing and QA, embedded systems, industrial engineering, IoT and AI work. Delivery is structured through Build-Operate-Transfer arrangements, Agile teams, and External Lab Solutions, giving clients different ways to staff and run engagements.

Platform partnerships extend to Microsoft, Adobe, Tricentis, Salesforce, Atlassian, SAP, ServiceNow, Google Cloud and Workday HCM, reflecting the range of enterprise systems the company builds on and integrates with. The mix of engineering disciplines — from embedded systems and industrial engineering through to cloud and cybersecurity — paired with reach into regulated industries such as banking, insurance and medical devices suggests an operation set up for clients needing both software delivery and hardware-adjacent engineering handled by a single provider.
