<Synthesia> Synthesia is a SaaS AI video platform that enables businesses to create studio-quality videos without cameras, microphones, actors, or studios by using AI avatars and synthetic voiceovers. The platform supports 160+ languages, one-click translation/localization, an AI screen recorder, brand management, collaboration and analytics, and enterprise-grade security (SOC 2 Type II, GDPR). It’s marketed primarily to teams and enterprises for training, sales enablement, marketing, knowledge management and internal communications, helping companies scale video production while reducing time and cost.

📋 Description

• You will work on core enterprise platform systems, focusing on backend services that ensure Synthesia is secure, reliable, and scalable for our largest customers. • You will contribute to distributed backend systems and shared platform services, and be responsible for the safe and reliable operation of these systems in production. • You will have ownership of projects that span months and multiple teams, requiring you to break down complex, ambiguous problems into clear steps that can be delivered and validated iteratively. • You will work closely with product, security, legal, and infrastructure partners, and will be expected to translate business and regulatory requirements into scalable technical solutions. • You will evaluate your work through system health and reliability metrics, leveraging observability and monitoring to ensure systems meet performance, reliability, and compliance expectations. • You will consider the long-term direction of the platform, ensuring that the systems we build today can support future scale, enterprise requirements, and evolving regulatory needs.

🎯 Requirements

• At least seven (7) years of experience as a software engineer, with experience operating at a senior or staff level. • You have experience building and operating backend systems at scale, ideally within platform or enterprise-focused teams. • Strong expertise in backend development and system design. Experience across the stack is a plus, but this role is primarily backend-focused. • Relevant engineering experience for teams building enterprise-grade systems; this may include areas such as security, compliance, data handling, access control, multi-tenant systems, or platform services. • Experience owning systems in production, including observability, incident response, and reliability improvements. • Ability to work across teams and functions, aligning with stakeholders and driving technical initiatives end-to-end. • Strong alignment with building reliable, scalable systems that support long-term product and business goals. • Previous experience leading projects or mentoring other engineers is a plus.

🏖️ Benefits

• 25 days of leave + local holidays
