Jobs at Synthesia

Own and evolve Synthesia's shared design system: build high-quality React/TypeScript components, design tokens, Storybook docs, accessibility (WCAG 2.2 AA), theming, localization/RTL, and tooling so both humans and AI agents can reliably consume components across products.

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.

Design and implement end-to-end full‑stack features for Avatars and generative media, integrating frontend, backend, and AI models. Own experiments from prototype to production, collaborate with product and design, ship behind feature flags, and iterate based on usage and model reliability.

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.

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.

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.

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.

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 own the speech and voice generation platform: backend orchestration for multiple TTS providers, voice discovery and recommendation systems, and frontend preview experiences. Scope and ship 0-to-1 features, iterate via experiments and feature flags, ensure reliability and quality across providers, and collaborate with product, design, and AI teams to measure and improve outcomes.

As a Product Manager, you will lead the strategy for a new product that assesses user readiness through real-time scenarios, driving customer engagement and commercial outcomes.

The role involves leading design for AI-native products at Synthesia, focusing on improving interaction patterns and enhancing user experience in AI-driven workflows.

Own the content lifecycle and governance for enterprise video deployments. Engage with customers to translate their needs into product direction and strategies. Ensure compliance and effective workflow between content creators and IT admins while driving towards commercial success through clear metrics and continuous product improvements.

Build and operate ML platform systems for training, evaluation, deployment, and serving of generative models. Improve reliability, scalability, performance, observability, and automation for GPU and cloud workloads. Develop internal tooling and agent-friendly workflows, collaborate with researchers and product engineers, and drive platform architecture and operational improvements.

As a Principal Product Manager, you will define the vision for the video editing platform, collaborate across teams, shape product strategy, and advocate for UX-focused features while ensuring high-performance scaling for enterprise users.

Lead design, implementation and operation of enterprise backend and platform services. Own distributed, multi-tenant systems in production, ensuring security, compliance, observability and reliability. Translate business and regulatory requirements into scalable technical solutions, drive cross-team initiatives, improve incident response and mentoring of engineers to support long-term platform scale and enterprise needs.

Lead multiple engineering teams to deliver growth-focused, user-facing projects. Prioritize experiments, scalability, and measurable business outcomes. Hire, develop, and align engineers to product and revenue goals while fostering a high-velocity, collaborative culture and clear cross-functional communication.

Design, build and scale an automated translation-quality evaluation framework for localisation and dubbing. Implement production ML evaluation infrastructure, roll it out across teams, align metrics with product signals, and maintain/iterate systems in collaboration with R&D and cross-functional partners.
