Senior backend engineer

About the Position

We are looking for a Senior Backend Engineer to help build the core services and user-facing tools that power a voice platform. In this role, you will develop and operate the platform's foundational backend systems while also building intuitive frontend experiences.

You will work across the full stack, designing scalable backend services and creating high-quality frontend applications that enable internal teams and partners to build, test, and manage voice experiences. This is an opportunity to work on distributed systems at scale, shape developer-facing tools, and own features from concept through production.

Responsibilities

• Design, build, and operate scalable backend services.
• Develop and maintain distributed systems using gRPC/HTTP APIs and event-driven architectures.
• Build cloud-native services with a strong focus on reliability, scalability, and performance.
• Own production systems end-to-end, including architecture, implementation, deployment, monitoring, and iteration.
• Partner closely with ML engineers to design robust interfaces between backend services and model-serving infrastructure.
• Collaborate with engineers and cross-functional stakeholders to deliver high-quality technical solutions.
• Champion engineering best practices, operational excellence, and maintainable system design.

Requirements

• 6+ years of experience building and operating distributed backend services.
• Strong professional experience with Java and Python. Experience with Java is essential, while Python is a plus because much of the team's tooling is built in it.
• Experience designing and developing gRPC/HTTP APIs, distributed systems, and event-driven architectures.
• Experience building and operating cloud-native infrastructure in production environments.
• Ownership of systems throughout their full lifecycle, from design through production support.
• Effective collaboration with machine learning teams and cross-functional partners.
• Excellent communication skills to explain technical trade-offs to both technical and non-technical stakeholders.
