Investigate production issues and improve service reliability, performance, and observability.
Write and review maintainable code, automated tests, design documentation, runbooks, and support guidance.
Partner with Product, frontend engineers, and adjacent platform teams to deliver cohesive customer workflows.
Mentor teammates through design discussions, code reviews, and collaborative problem solving.

What You’ll Bring

Ability to own complex work end to end, manage competing priorities, and communicate risks and tradeoffs early.
A customer- and security-conscious approach to designing administration and access workflows.
Strong analytical and problem-solving skills, attention to detail, and commitment to high-quality production software.
Clear technical writing and effective collaboration with Product and engineering partners
Interest in sharing knowledge and helping other engineers grow.

Required Education / Experience

Bachelor’s degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience.
7+ years of professional software engineering experience building production software with a modern programming language.
Experience designing and operating backend services and APIs, and taking complex work from design through production.

Experience building services on a cloud platform such as AWS, GCP, or Azure and working with Docker or other containerized applications.
Demonstrated focus on testing, production reliability, observability, and clear technical communication.
Experience with every listed language or framework is not required; depth in relevant areas and the ability to learn are important.

What Sets You Apart?

Experience with multi-tenant SaaS, RBAC, SSO, audit logs, delegated administration, or account hierarchy models.
Experience with Python or Go, PostgreSQL, GraphQL, Kubernetes, and CI/CD.
