Top Tech Jobs & Startup Jobs in Dublin

Senior/Staff Product Designer on Growth focused on onboarding, first-time editor experiences, activation and retention. Rethink complex AI-native user journeys, translate ambiguous problems into prototypes and experiments, partner with PMs and engineers to move metrics, and mentor designers while elevating AI-generated prototypes into scalable experiences.

Develop and optimize real-time generative speech and voice synthesis systems. Work on streaming and speech-to-speech models, conditioning inputs (emotion, prosody, speaker control), post-training optimizations (quantization, pruning, distillation), integrate novel architectures (neural codecs, diffusion, flow-matching), and define latency-aware evaluation metrics for production deployment.

Join Synthesia's Cloud Infra team to maintain and scale EKS Kubernetes clusters, manage AWS/GCP infrastructure, own GitHub Actions CI/CD on self-hosted runners, implement Terraform/Terragrunt IaC, enhance observability with Datadog, drive FinOps, and build internal tooling to improve developer experience.

Manage Spanish enterprise accounts, drive retention and expansion, onboard clients, build trusted advisor relationships, coordinate cross-functional success plans, conduct executive-level conversations, and perform light video editing using the Synthesia platform.

Manage a book of Italian enterprise accounts, onboard and educate clients on Synthesia, drive retention and growth, run regular health check-ins, identify risks and expansion opportunities, and engage with stakeholders up to the C-suite while performing light video editing on the Synthesia platform.

Lead technical validation and solution design for prospects and customers: run discovery, design pilots/demos, drive first-value adoption, enable expansion, and build repeatable playbooks across Sales, Customer Success, and Product.

Develop and productionize avatar-centric video diffusion models: incorporate multimodal conditioning, enable real-time long video streaming, improve lip-sync and motion realism, build evaluation frameworks, collaborate with data teams, and translate research into product features.

Drive technical validation and value realization across prospects and customers. Lead discovery, design solutions, run pilots/demos, ensure first live workflows and early adoption, enable expansion, build repeatable playbooks, and partner cross-functionally with Sales, Customer Success, Product, and Marketing to translate customer needs into measurable business outcomes.

Develop and deploy post-training techniques for generative video and avatar models. Apply DPO, adapt conditioning, build dubbing and lip-sync solutions, and optimize diffusion models via quantization, pruning and distillation to improve efficiency and rendering quality.

Build and operate ML platform systems for training, evaluation, deployment, and serving. Improve reliability, scalability, cost-efficiency, observability, and automation for GPU and cloud workloads. Develop internal tools and agent-friendly workflows, collaborate with researchers and product engineers, and drive platform architecture and developer experience.
