Senior Systems Software Engineer

Job Title

Senior Systems Software Engineer

Role Summary

Owner of reliability, automation, and evolution for core platform systems. Work spans backend, infrastructure, and system-level engineering to ensure the platform is performant, scalable, and maintainable.

Collaborate with engineering teams to build tooling, integrations, and operational automation; step into frontend work when necessary to resolve system-level issues.

Experience Level

Senior-level. No specific years-of-experience requirement stated in the posting.

Responsibilities

Provide technical ownership of systems, tooling, and infrastructure that support the platform.

• Design, implement, and maintain core systems and services for reliability, performance, and scalability.
• Build automation and developer tooling to reduce operational overhead and enforce consistency.
• Develop integrations with external platforms (billing, CRM, authentication, analytics).
• Improve observability, monitoring, and alerting across services.
• Architect and maintain infrastructure components (distributed services, data pipelines, deployment automation).
• Contribute to security-related systems such as permissions, access flows, and auditability.
• Troubleshoot and resolve issues across backend, infrastructure, and occasionally frontend layers.
• Occasionally modify frontend code to close the loop on system-level changes or unblock reliability issues.

Requirements

Key technical skills and must-have experience for success in this role.

• Strong professional experience in systems, platform, or infrastructure engineering.
• Proficiency in Rust and systems-level programming.
• Experience with databases (transactional and analytical): 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.
• Experience with infrastructure-as-code and containerized deployment workflows.
• Ability to work autonomously and make high-leverage technical decisions in a fast-moving environment.
• Bias toward automation and building tools to remove operational friction.

Nice-to-have:

• Frontend experience (JavaScript/React) for occasional UI fixes.
• Experience with billing systems (Stripe) or CRM platforms.
• Background building internal tooling, permissions systems, or developer productivity infrastructure.
• Familiarity with CAD-adjacent workflows or domain-specific data pipelines.

Education Requirements

B.S. in Computer Science or a related field, or equivalent practical experience.
