Senior Software Engineer – Test Automation

• Overview
• One Identity's One Login team is seeking

Senior 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 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
• 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
• 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., Git Hub Copilot, Chat GPT, Cursor).
• Ability to review and validate AI-generated code and suggestions.
