Why this role matters
As osapiens grows its platform and expands its partner ecosystem, the bridge between the core platform and the developers building on top of it becomes mission-critical. This role owns that bridge: ensuring application teams and external partners have the tools, frameworks, documentation, and community support they need to build with confidence on the osapiens HUB. You directly shape how efficiently and consistently development happens across the organization and beyond.
This position follows a hybrid work model with a requirement to be in the office three times per week.
