About the role
Software Engineer focused on building and maintaining Middesk's infrastructure, with responsibilities spanning reliability, security, automation, cost, developer experience, and internal platforms. Involves working with AI-enabled infrastructure and collaboration tooling, with a hybrid in-person component in San Francisco.
Responsibilities
- Design, build, and scale cloud infrastructure and orchestration systems, including Kubernetes, Terraform, and CI/CD, with support from senior engineers who are invested in your growth.
- Own and evolve developer experience (DevEx) tools and workflows, from local development to deployment.
- Build observability systems that provide insight into performance, reliability, and usage.
- Improve the reliability of our production systems through safer deploys, automated rollback, failover, and platform hardening.
- Collaborate with Data Scientists, Data Platform and Product Engineers to build shared platform tools necessary to scale our products and services.
- Help enforce and maintain security and compliance standards across infrastructure (SOC 2, FedRAMP, etc).
- Drive a culture of automation, resiliency, and operational excellence.
- Build the infrastructure underneath how AI is changing work at Middesk, including systems that let engineers, operators, and agents collaborate safely and effectively.
Qualifications
- 3+ years of experience as a software engineer, with genuine interest in infrastructure, platform, or systems work
- Strong technical fundamentals: a deep, careful understanding of how systems actually work
- A fast learner who is reliable, humble, and excited to absorb everything from experienced teammates
- Comfort with (or excitement about) work that isn't customer-facing – the impact here is deep, not loud.
