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. ## 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 ## Related Videos - [Back to the Roots: Testing in the Age of AI](https://www.wearedevelopers.com/videos/100021-back-to-the-roots-testing-in-the-age-of-ai) - [ Evaluating AI models for code comprehension](https://www.wearedevelopers.com/videos/1462-evaluating-ai-models-for-code-comprehension) - [Coffee with Developers: David Heinemeier Hansson](https://www.wearedevelopers.com/videos/875-coffee-with-developers-david-heinemeier-hansson) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Hiring AI Native Talents](https://www.wearedevelopers.com/videos/100268-hiring-ai-native-talents) - [Streaming AI Responses in Real-Time with SSE in Next.js & NestJS](https://www.wearedevelopers.com/videos/1630-streaming-ai-responses-in-real-time-with-sse-in-next-js-nestjs) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [13 AI Tools for Developers](https://www.wearedevelopers.com/magazine/302-13-ai-tools-for-developers) - [What is Software Engineering in the Age of AI?](https://www.wearedevelopers.com/magazine/640-what-is-software-engineering-in-the-age-of-ai)
