To address the challenge of matching recommendations in dynamic, text-rich two-sided job markets, this paper proposes an end-to-end joint learning framework that pioneers deep integration of pretrained language models (PLMs) and temporal graph neural networks (GNNs). Specifically, PLMs capture fine-grained semantic evolution from job postings and candidate profiles, while moment-wise subgraph sampling and adversarial negative sampling jointly model structural and temporal dynamics of interaction graphs. The method overcomes longstanding bottlenecks in synergistic language–graph representation learning and incorporates low-latency inference optimizations for scalable real-time deployment. Evaluated on the real-world Upwork dataset, it significantly outperforms unimodal baselines—both pure language- and pure graph-based—achieving superior matching accuracy and computational efficiency. The system has been successfully deployed in production.
