Secure Every Identity, from AI to Human

Identity is the key to unlocking the potential of AI. Okta secures AI by building the trusted, neutral infrastructure that enables organizations to safely embrace this new era. This work requires a relentless drive to solve complex challenges with real-world stakes. We are looking for builders and owners who operate with speed and urgency and execute with excellence.

This is an opportunity to do career-defining work. We're all in on this mission. If you are too, let's talk.

The Identity Security Pillar

Our Identity Security Organization Keeps Okta Customers Safe By Detecting, Preventing, And Responding To Identity-based Attacks In Real Time, At The Scale Of The World's Largest Identity Cloud. We Have Multiple Open Positions Across Teams That Own

Identity Threat Protection (ITP) and Identity Security Posture Management (ISPM), including the integration of Permiso's non-human identity and cloud entitlement risk detection into Okta's threat detection stack
Essential Security, the core threat detection and protection capabilities every Okta customer relies on, including Threat Insight, the Orbit detection engine, enriched proxy/anonymizer intelligence, breached-credential detection (SpyCloud), Attack Protection, and Adaptive OIE

You'll work shoulder-to-shoulder with engineers who care deeply about shipping high-quality, resilient detection systems that hold up under real-world attack traffic and that customers can trust to keep their organizations safe.

Senior Software Engineer in Test - Identity Security (Multiple Positions)

We seek experienced Senior Software Engineers in Test to join our Identity Security engineering teams. You'll own test strategy and automation for real-time detection pipelines, risk signal correlation, and third-party integrations, and ensure new capabilities ship with zero-debt quality across every new cell and platform upgrade. Team placement will be based on experience and business needs.

Job Duties And Responsibilities

Review requirements and design specs to develop test plans and test cases for detection, protection, and posture management features
Own end-to-end test coverage for complex signal and product integrations, including data ingestion, risk signal correlation, and detection pipelines (e.g., ITP-Permiso integration)
Automate API, end-to-end, and reliability/scale tests for real-time detection pipelines (Kafka → KDA → DynamoDB & BigTable)
Simulate real-world attack vectors, generate synthetic load, and benchmark latency for detection pipelines
Validate new cell rollouts across OIE orgs (e.g., Orbit enforcement, Threat Insight detection, ITP/ISPM features, data-lake IP allowlists)
Own test support for platform-wide initiatives (e.g., Monolith Spring library upgrades) affecting Identity Security surfaces
Triage and drive resolution of P0 defects, working cross-functionally with product engineering and integrated partner teams
Continuously improve automated regression coverage, in partnership with development teams
Review application code, identify bugs and other areas of weakness, and architect tools for future coverage
Own release sign-off and respond to production issues, P0/P1 alerts, and customer issues during on-call rotation
Be a strong customer advocate with a strong quality DNA

Requirements

Minimum of a Bachelor's degree in software engineering (or related)
4+ years of SDET experience, with a deep focus on enterprise SaaS backend distributed systems, REST APIs, and asynchronous data pipelines
Experience in test engineering for enterprise-level software, ideally in the identity or security domain
Strong programming proficiency in Java or Python (TypeScript a plus)
Familiarity with automation and observability tools like Playwright, Selenium, TestCafe, API (Rest Assured, Karate, etc.), Postman, JMeter, Runscope, Splunk, Grafana, and AWS toolset
Hands-on experience testing event-driven or streaming platforms (e.g., Apache Kafka, Kinesis, KDA) and distributed databases/caches (e.g., DynamoDB, Redis, BigTable)
Experience with automation and testing of complex signal and product integrations
Expertise in test planning and cross-team collaborative efforts, including across integrated third-party or acquired tech stacks
Experience with continuous integration/continuous deployment (CI/CD) practices
Experience working with distributed systems at large scale
Able to write and review designs and code with other team members
Able to deliver well-designed, high-quality code on time

Nice To Have

Experience with threat detection, fraud, or attack/bot mitigation systems
Experience with cloud security posture management (CSPM) or identity security posture management (ISPM) concepts
Familiarity with non-human identity or entitlement risk models
Familiarity with third-party threat-intel integrations (e.g., breached credential feeds)
Experience integrating an acquired company's tech stack into an existing platform
Good understanding of IAM solutions along with SAML/OIDC protocols
Experience with AI-native Software Development Life Cycle (SDLC) standards and practices
