Jobs at Synthesia

Lead and grow a senior Application Security engineering team; define AppSec strategy and roadmap; engage deeply on threat modelling, security architecture, agentic/AI-native tooling, SAST/SCA, vulnerability management and automation; embed security into the SDLC, coordinate with leadership and partner teams, and represent AppSec externally for compliance and customer interactions.

Own growth for a core product area end-to-end (acquisition, activation, adoption, retention). Partner with product, engineering, marketing and GTM to design growth into the product, build acquisition loops, define measurable outcomes, and rally cross-functional teams to hit funnel and activation metrics.

Lead applied research and engineering to build production-grade video foundation models. Work includes developing latent video diffusion models, designing conditioning for controllability, scaling distributed multi-GPU training, improving training stability, building evaluation frameworks, and optimizing inference for low-latency, high-resolution deployment.

Lead end-to-end technical direction for offline video generation: bridge pre- and post-training, resolve cross-cutting technical gaps, define long-term roadmap with research leadership, accelerate research-to-product handoffs, coach engineers, and drive execution on large-scale generative video models.

Build and operate large-scale data pipelines and orchestration for generative AI research, focusing on video/audio datasets, feature extraction, labeling, and dataset quality to improve model performance.

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 operate ML platform systems to train, evaluate, deploy, and serve generative models. Improve reliability, scalability, observability, and cost-efficiency of GPU and cloud workloads. Build internal tools and agent-friendly workflows, collaborate with researchers and engineers, and drive platform architecture and automation.

Lead research and engineering for interactive multimodal generative models (text, audio, video). Propose architectures, implement pretraining and post-training, optimize low-latency streaming systems, curate datasets, define evaluation metrics, and ship production models with runtime optimizations and ongoing improvements.

Lead and evolve Synthesia's experiential brand presence globally: design booths, spatial environments, signage, print and merchandise; create cohesive physical-to-digital event identities; storyboard and craft motion/screen content; manage production and supplier-ready files; direct vendors and on-site execution; collaborate with Field Marketing and cross-functional teams to deliver scalable, production-ready experiences.

Own and evolve the marketing website platform: design Sanity content schemas, build Astro components and design-token-driven UI, ensure accessibility (WCAG 2.2 AA), SEO, localization and performance, extend tooling for AI-assisted composition, and ship end-to-end features from schema to production.

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.

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.

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.

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.
