Senior Systems Software Engineer

About the role

About Us

Zoo is building the next generation of hardware design tools redefining how hardware products are designed, developed, and built. Our platform combines a modern, cloud-native CAD environment with AI-powered engineering workflows, helping teams design, iterate, and manufacture products faster than ever before. We are headquartered in Los Angeles, CA with both a local and remote team. We were founded and incubated by Embedded Ventures in 2021.

About You

We’re looking for curious, innovative, and ambitious self-starters to join our growing team to help us bring our mission to life. We think you’ll thrive on our team if you’re:

- Curious at your core, with an eagerness to learn and do things differently

- Customer-focused, always thinking about ways to improve the user experience

- Able to operate autonomously and work asynchronously, while also being an effective team player

About The Role

We’re looking for a Senior Systems Software Engineer who can take ownership of the reliability, automation, and evolution of our core systems. You’ll work across the stack, with a strong emphasis on backend, infrastructure, and system-level engineering, to strengthen the foundations that everything else runs on. This role is for someone who enjoys digging into complex systems, building the tooling and automation that keep them running smoothly, and stepping in anywhere (including the frontend) when something needs fixing.

What You’ll Do

- 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.

What You’ll Need

- 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.
