Job description

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 tooperateas T-shaped engineers: deep in a primary domain whileremainingcapable across the stack (backend, APIs, cloud, and operations). You will play a key role inmaintainingproduct 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, andoperate— 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 whilemaintainingreliability and system continuity.

Responsibilities

Execute and evolve an incremental modernization strategy, safely transitioning legacy systems into well-bounded services whilemaintainingreliability 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
• Identifyand prioritize high-impact areas for migration based on risk and value

Ideal Experience:

• 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
• Experiencemaintainingbackward 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 tovalidatesystem behavior during migrations
• Experience using AI tools to analyze legacy systems, understand behavior, or accelerate refactoring and migration efforts

Qualifications

Software Development

• 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

Quality & Testing

• Hands-on experience with automated testing across unit, integration, and API layers
• Strong ownership of code quality, including testing, debugging, and validation

AWS & Cloud-Native Experience

• Experience building and operating cloud-native services in AWS
• Familiarity with CI/CD practices and modern deployment workflows

Observability & Production Operations

• Experience using observability tools (e.g. Datadog or equivalent) to monitor, troubleshoot, and resolve production issues
• Familiarity with incident response and continuous reliability improvements

On-Call & Incident Response

• Willingness to participate in a 24/7 on-call rotation and support production issue resolution

AI-Augmented Engineering

• 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
