Senior Software Engineer – Test Automation

Overview

One Identity's OneLogin team is seeking Senior 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 focus on designing and evolving testing strategy and automation systems that maximize confidence while minimizing feedback time — eliminating manual QA dependency and improving release safety at scale. 

Responsibilities

• Design, build, and operate OneLogin IAM services and APIs, supporting millions of authentication requests across a globally distributed SaaS infrastructure 
• Own the full development lifecycle: requirements, design, implementation, testing, deployment, and documentation 
• Define and own test strategy and coverage across services, balancing speed, reliability, and risk 
• Continuously improve test coverage using production insights, failure patterns, and risk-based prioritization 
• Take end-to-end ownership of production systems, including on-call, incident response, and reliability improvements 
• Proactively identify and resolve high-impact issues using logs, metrics, and tracing; contribute to root cause analysis and prevention 
• Build quality into development by creating and maintaining automated test suites (unit, integration, end-to-end) and thoroughly validating code 
• Write and optimize SQL in PostgreSQL/Amazon Aurora, including query analysis, indexing, performance tuning, and data maintenance 
• Participate in design reviews, code reviews, and cross-team initiatives (architecture evolution, platform improvements, security) 
• Partner with Product, Platform Engineering, and stakeholders to prioritize and deliver work end-to-end 
• Ensure application security, data integrity, compliance, and system reliability as core engineering responsibilities 
• Contribute to and operate within AWS cloud-native environments, collaborating with platform teams on architecture and scalability 
• Leverage AI-powered tools to accelerate development, testing, debugging, incident analysis, and documentation, applying critical judgment to outputs

Qualifications

Software Engineering

• 4+ years of professional software engineering experience with ownership of features, quality, or system-level initiatives.
• Strong backend development experience (Ruby, Node.js, or similar).
• Solid understanding of REST APIs, service contracts, and software design principles.
• Experience working across backend services, APIs, and production systems.

Quality Engineering

• Experience designing and maintaining automated tests across unit, integration, and end-to-end levels.
• Familiarity with modern testing frameworks (e.g., Playwright, Cypress).
• Strong ownership of code quality, debugging, and testing strategy, balancing coverage, reliability, and execution time.

Cloud & Production Systems

• Experience building and operating services in AWS or similar cloud environments.
• Good understanding of cloud-native and distributed systems (microservices, scalability, resilience).
• Experience with CI/CD, production debugging, observability tools (e.g., Datadog), and incident response.

On-Call & Reliability

• Willingness to participate in a mandatory 24/7 on-call rotation.
• Experience responding to production incidents and contributing to reliability improvements and postmortems.

AI-Assisted Development

• Experience using, or strong interest in, AI-powered development tools (e.g., GitHub Copilot, ChatGPT, Cursor).
• Ability to review and validate AI-generated code and suggestions.
