[Hiring] Staff Software Engineer @One Identity

Role Description

One Identity's OneLogin team is seeking Staff Software Engineers who operate with high ownership, strong technical judgment, and a bias for action. These roles are designed for engineers who identify and solve problems proactively — not just execute assigned work.

Senior Engineers at OneLogin are expected to operate as T-shaped engineers: deep in a primary domain while remaining capable across the stack (backend, APIs, cloud, and operations). You will play a key role in maintaining product velocity, improving system reliability, and reducing operational burden.

This is a hands-on role that includes on-call responsibilities and requires a strong commitment to modern engineering practices, including AI-augmented development. We are looking for engineers who take full ownership — design, build, test, deploy, and operate — rather than handing work off between silos.

In this role, you will execute and evolve an incremental modernization strategy (e.g., strangler fig), safely transitioning legacy systems into scalable services while maintaining reliability and system continuity.

Responsibilities

• Execute and evolve an incremental modernization strategy, safely transitioning legacy systems into well-bounded services while maintaining reliability and continuity
• Decompose monolithic systems incrementally using patterns such as strangler fig
• Manage coexistence between legacy and modern systems during transition
• Design clear service boundaries, contracts, and data ownership models
• Ensure backward compatibility and safe evolution of APIs and data during migration
• Improve performance, scalability, and maintainability as part of modernization efforts
• Identify and prioritize high-impact areas for migration based on risk and value

Qualifications

• 4+ years of professional software engineering experience with ownership of production systems and operational improvements
• Strong backend development experience (Ruby, Node.js, or similar)
• Solid understanding of REST APIs, service contracts, distributed systems, and common software design patterns
• Experience working across backend systems, APIs, and production environments
• Hands-on experience with automated testing across unit, integration, and API layers
• Strong ownership of code quality, including testing, debugging, and validation
• Experience building and operating cloud-native services in AWS
• Familiarity with CI/CD practices and modern deployment workflows
• Experience using observability tools (e.g. Datadog or equivalent) to monitor, troubleshoot, and resolve production issues
• Familiarity with incident response and continuous reliability improvements
• Willingness to participate in a 24/7 on-call rotation and support production issue resolution
• Experience with or strong interest in AI-assisted development tools (e.g. GitHub Copilot, ChatGPT, Cursor) and the ability to effectively evaluate AI-generated solutions
