Senior Systems Software Engineer

Zoo is building the next generation of hardware design tools, combining a modern, cloud-native CAD environment with AI-powered engineering workflows. They are seeking a Senior Systems Software Engineer to take ownership of the reliability, automation, and evolution of their core systems, with a focus on backend, infrastructure, and system-level engineering.

Responsibilities:

• Design, implement, and maintain core systems and services that support our platform’s reliability, performance, and scalability
• Build automation and tooling that reduce operational overhead, improve developer workflows, and enforce system-level consistency
• Develop integrations between our systems and external platforms (e.g., billing, CRM, authentication, analytics)
• Improve observability, monitoring, and alerting across services to ensure strong operational visibility
• Architect and maintain infrastructure components (e.g., distributed services, data pipelines, deployment automation)
• Contribute to security-focused systems work, such as permissions controls, access flows, and auditability
• Troubleshoot issues across services and layers, backend, infrastructure, and occasionally frontend, taking full ownership from diagnosis to resolution
• Jump into frontend code as needed to close the loop on system-level changes or fix issues that block broader system reliability

Requirements:

• B.S. in Computer Science or a related field, or equivalent experience
• Strong professional experience in systems, platform, or infrastructure engineering
• Proficiency in Rust with a solid understanding of systems-level programming
• Solid experience with databases (transactional & analytical) including schema design, performance tuning, migrations, and operational reliability
• Strong understanding of API design, data flows, and service integrations
• Hands-on experience with distributed systems or service-oriented architectures
• Comfort working with infrastructure-as-code and containerized deployments
• Ability to work autonomously and make high-leverage technical decisions in a fast-moving environment
• A bias toward automation and building tools that remove friction
• Experience with frontend development (JavaScript/React) for occasional UI-level fixes
• Background with billing systems (Stripe) or CRM platforms
• Experience building internal tooling, permissions systems, or developer productivity infrastructure
• Familiarity with CAD-adjacent workflows or domain-specific data pipelines
