Senior Software Engineer – Test Automation

Overview

One Identity's One Login team is seeking Staff Software Engineer
s 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 One Login 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, and operate— rather than handing work off between  this role, you will focus on designing and evolving testingstrategyand automation systems that maximize confidence while minimizing feedback time —eliminating manual QA dependency and improving release safety at scale.

Eliminate manual QA dependency and build scalable automated testing

• Design and evolve test architecture and tooling that scales across services and teams
• Design and implement end-to-end, integration, and API test automation
• Own test strategy across services —determine what to test, where to test it (unit vs integration vs E2E), and how to maximize signal while minimizing runtime
• Improve CI/CD confidence and release safety while increasing deployment velocity
• Reduce regression risk through targeted, high-value test coverage rather than brute-force test expansion
• Own test reliability — proactively detect, diagnose, andeliminateflaky or low-signal tests

Ideal

Experience:

• Experience with modern test frameworks (Playwright, Cypress, or similar)
• Strong understanding of testing strategy across layers (unit, integration, API, E2E) and when to apply each
• Experienceoptimizingtest suites for speed vs coverage (e.g., test selection, parallelization, flake reduction)
• Experience integrating tests into CI/CD pipelines with a focus on fast feedback loops
• Experience using AI tools to accelerate testing workflows, including:
• Using AI to generate, prioritize, andoptimizetest coverage based on risk and system behavior
• Analyzing test failures and flaky patterns at scale using AI-assisted tooling
• Accelerating test maintenance, refactoring, and gap detection
• Ability to use data (incidents, logs, usage patterns) to continuously refine and prioritize test coverage
• Experience with API and contract testing

• 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.

• 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.

• 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.

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

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