Role overview
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).
Responsibilities
- Execute and evolve an incremental modernization strategy (e.g., strangler fig), safely transitioning legacy systems into well-bounded, scalable services while maintaining reliability and system 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
- Maintain product velocity and improve system reliability
- Reduce operational burden
- Take full ownership of design, build, test, deploy, and operate work rather than handing work off between silos
- Participate in a 24/7 on-call rotation and support production issue resolution
Requirements
- 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
- Strong commitment to modern engineering practices, including AI-augmented development
Nice to have
- Hands-on experience incrementally modernizing monolithic systems in production environments
- Experience with migration patterns such as strangler fig, parallel run, or phased rollouts
- Strong understanding of system decomposition, including service boundaries and data ownership
- Experience maintaining backward compatibility and managing API/data contracts during system evolution
- Experience working with legacy systems and evolving them under real-world constraints
- Experience debugging and validating behavior across both legacy and newly extracted services
- Ability to balance migration velocity with system stability and risk
- Familiarity with observability practices to validate system behavior during migrations
- Experience using AI tools to analyze legacy systems, understand behavior, or accelerate refactoring and migration efforts
- 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
