Staff Backend Engineer, Voices

Accountabilities

• Design, build, and maintain backend systems powering script preview and voice generation workflows at scale.


• Develop and operate orchestration layers that integrate multiple text-to-speech providers alongside internal AI models.


• Implement reliability mechanisms such as retries, failover strategies, throttling, and fallback logic for external API dependencies.


• Design persistence and data consistency systems ensuring reproducible and high-quality voice outputs across generations.


• Improve storage, retrieval, and reuse mechanisms for voice assets across the platform.


• Build and enhance evaluation and recommendation systems for voice discovery and selection.


• Monitor system performance and user experience metrics using observability tools to identify issues and drive improvements.


• Collaborate closely with frontend and product teams to design APIs and workflows that deliver seamless end-user experiences.


• Contribute to cross-functional initiatives spanning backend infrastructure, product logic, and applied AI systems.


• Participate in iterative development cycles, shipping quickly and refining systems based on data and user feedback.

Requirements

• Several years of experience designing, building, and operating production-grade backend systems.


• Strong proficiency in backend development (Python/FastAPI or similar frameworks) with experience in distributed systems.


• Proven ability to work with third-party APIs and manage external service dependencies in production environments.


• Strong product mindset with focus on user-facing impact rather than purely technical implementation.


• Experience designing reliable, observable, and scalable backend services.


• Understanding of system design principles, including consistency, latency, and fault tolerance.


• Ability to collaborate across frontend, backend, and product teams, with comfort working across the full stack when needed.


• Experience working in iterative, experiment-driven environments with fast shipping and continuous improvement.


• Familiarity with observability tools (e.g., Datadog), workflow orchestration systems (e.g., Temporal), or recommendation/evaluation systems is a plus.


• Strong communication skills and ability to translate technical decisions into product outcomes.


• Curiosity and willingness to explore unfamiliar areas, including frontend debugging when required.

Benefits

• Competitive base salary starting from EUR/GBP/CHF 130,000 plus stock option plan.


• 25 days of annual leave plus local public holidays.


• Remote-first flexibility within eligible regions (EU, UK, Switzerland).


• Opportunity to work on industry-leading AI voice generation technology.


• Exposure to cutting-edge generative AI research and production systems.


• Fast-paced, product-driven engineering culture focused on execution over process.


• High-impact role with direct influence on end-user experience at scale.


• Collaborative environment working with world-class engineers, researchers, and product teams.


• Strong emphasis on ownership, autonomy, and continuous learning.
