Background: Low and uneven conversion when digital platforms rely on generic, single-channel communication limits responsive, fair, and sustained developer participation. 
Purpose: This conceptual review integrates research and institutional guidance published to date to explain the problem and develop an actionable framework for global platforms connecting software developers with remote opportunities. 
Method: The paper uses an integrative review organized around demand definition, evidence, interaction, decisions, transition, and feedback. 
Results: The synthesis identifies six recurring requirements: clear demand signals, job-relevant evidence, accessible communication, multidimensional matching, transition support, and governed learning. It proposes a five-stage model comprising Audience segmentation, Channel orchestration, Message relevance, Friction removal, Conversion learning. The model pairs each stage with controls and measures, including demand stability, evidence quality, conversion, time to contribution, sustained performance, and fairness indicators. 
Conclusion: Developer engagement on global talent platforms should be managed as a connected socio-technical system. Organizations should pilot the model in a bounded role family, compare outcomes with a baseline, examine unequal effects, and revise the process before scaling.
