Job description

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

Requirements

  • 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:

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.
