Jobs at Synthesia

Own the architecture, delivery, and operational health of internal developer platforms, CI/CD systems, observability, testing infrastructure, and AI-assisted development tools. Lead multi-quarter technical projects, shape roadmap and strategy with leadership, mentor engineers, and improve developer velocity through scalable tooling. Drive adoption of AI-powered developer capabilities, integrate third-party services, and provide long-term technical direction for the platform engineering organization.

Owns end-to-end proposal, RFP, and RFI processes for strategic and enterprise sales opportunities. Coordinates cross-functional inputs from Sales, Finance, Legal, RevOps, Infosec, and Services; manages security questionnaires, due diligence, vendor registrations, and procurement portals. Produces accurate customer-facing documentation, supports deal execution, and improves RFP workflows and knowledge management using Salesforce, Slack, and related systems.

Lead multiple engineering teams building the Agents Platform, a reliable, low-latency foundation supporting models, voices, and downstream products. Drive complex projects, prioritize work with product and data teams, balance speed and scalability, scale engineering talent, monitor performance, and support career development. Partner with R&D to productionize AI technology and align platform delivery with business, growth, and revenue goals.

Develop and scale production-grade video foundation models for human-centric video generation. Lead applied research and engineering projects involving diffusion modeling, conditioning, distributed multi-node training, evaluation, ablation studies, inference optimization, reproducibility, monitoring, and production deployment. Collaborate across teams to deliver stable, controllable, high-quality, cost-efficient video generation systems.

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.

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.

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.

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 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.

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.
