1G-Link is a 11–50 person consulting firm migrating clients away from legacy ERP (SAP ECC → S/4HANA) while building internal capability around cloud data platforms (Snowflake, Power BI) and microservices. The stack—Java/Spring on Kubernetes, Kafka for streaming, PostgreSQL/MongoDB—reflects hands-on delivery work, not just advisory. Hiring velocity is accelerating with a senior-heavy mix (3 lead/senior roles in 6 active openings), signaling growth in presales and technical delivery leadership rather than junior scaling.
