Join Tether and Shape the Future of Digital Finance. At Tether, we’re building solutions that enable reserve-backed tokens across blockchains. Our technology supports storing, sending, and receiving digital tokens globally with transparency and trust.

Our team is a global, remote workforce. If you’re passionate about fintech, collaborate with leading minds and contribute to a fast-growing leader in the industry. Excellent English communication skills are a plus.

We’re seeking experienced AI infrastructure engineers to design and implement robust, scalable pipelines for massive data workloads. Join Tether’s applied research team to contribute to high-impact projects across thousands of GPUs and video generation foundation development.

• Build and scale high-throughput data infrastructure optimized for video and multimodal content processing across large GPU clusters (e.g., H100/H200).


• Design core preprocessing algorithms for video, audio, text, and image modalities, enabling efficient extraction, synchronization, and normalization of temporal data.


• Build automated acquisition pipelines for sourcing large-scale video datasets, handling diverse formats, frame rates, annotations, and embedded audio.


• Architect robust systems for scalable evaluation and annotation, including prompt-based scoring, perceptual metrics, caption generation, and retrieval-based diagnostics.


• Collaborate with model researchers to co-design video model architectures (e.g. DiTs, VAEs, spatio-temporal transformers) and training schedules across pretraining and fine-tuning stages.


• Optimize distributed data loading and pipeline throughput for training at scale, ensuring robustness across model variants and modality combinations.


• Manage infrastructure to support experiment tracking, model versioning, and cross-team deployment workflows, integrating with production and research platforms.


• Support backend engineering across research, product, and creative teams to ensure seamless integration of data and model workflows from prototyping to inference.

• Proficient in Python with strong programming skills across backend, infrastructure, and data tooling domains.


• Strong software engineering experience, including 2+ years working with petabyte-scale data pipelines and systems across thousands of GPUs.


• Proven ability to architect and maintain large-scale distributed systems for data processing and delivery.


• Deep expertise in orchestration frameworks such as Kubernetes and SLURM with hands-on experience deploying and managing high-throughput workloads.

• Practical experience on building pipelines and infrastructure with visual and multimodal datasets, including image/video pipelines.


• Experience in building video foundation infrastructure pipelines and workflows with collaboration of LLM and/or video foundation research and engineering teams is a strong advantage.

• Apply only through our official channels. We do not use third-party platforms or agencies for recruitment unless clearly stated. All open roles are listed on our official careers page: tether.recruitee.com
