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:
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, and eliminate flaky or low-signal tests
- 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
- Experience optimizing test 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, and optimize test 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
Qualifications:
-
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., GitHub Copilot, ChatGPT, Cursor).
-
Ability to review and validate AI-generated code and suggestions.
