Job summary

Simbian, Inc. in Bangalore (Remote, India) seeks an experienced SDET to own quality engineering for the Simbian platform end-to-end.

You will build automated test frameworks from the ground up, embed testability into the platform, and define release-readiness for a multi-tenant, AI-powered security platform. You will collaborate with engineering, product, and security teams, integrate tests into CI/CD, and drive flaky-test reduction while maintaining fast feedback.

Qualifications

• 6–10 years of professional SDET or quality engineering experience.
• Hands-on experience with API automation (REST, GraphQL) and UI automation (Playwright, Selenium, Cypress) or equivalent.
• Experience integrating test suites into CI/CD pipelines (GitHub Actions, Jenkins, or equivalent).
• Experience with containerized test environments using Docker and Kubernetes.
• Demonstrated ability to design test strategy independently for multi-tenancy, RBAC, etc.
• Strong debugging skills and ownership mindset.

Responsibilities

• Own the automated test framework covering UI, API, and integration layers for a multi-tenant web platform.
• Design and implement test suites that are reliable, maintainable, and fast in CI.
• Drive flaky-test reduction and maintain health of the regression suite over time.
• Establish test patterns and tooling that engineers can use independently.
• Define coverage targets and release-readiness signals trusted by the team.
• Build and maintain regression suites protecting against regressions as the platform evolves.
• Identify gaps in coverage and prioritize fixes based on risk.
• Integrate test suites into CI/CD pipelines and enforce quality gates.

Job description

Bangalore (Remote), India | Posted on 08/24/2026

Simbian® is building Agentic AI platform for cybersecurity. Founded by repeat successful security founders, we have gathered an excellent cohort of employees, partners, and customers.

Our mission is to solve security using AI and our core values are excellence, replication, and intellectual honesty.

Our promise is to make Simbian the best workplace of your career and we believe a small group of thoughtful passionate people can make all the positive difference in the world.

To fuel our fast growth, we are seeking an exceptional candidate who shares our core values of excellence (being the world's best at our craft), replication (share your best ideas with others), and intellectual honesty (tell the truth even if it's bitter).

Our AI Agents automate security operations and provide our customers 10x leverage. Our customers include some of the world's largest companies. Our initial use cases include:

• SOC alert triage and investigation
  
• Prioritization and classification of vulnerabilities
  
• AI based threat hunting

Job Description

The Role

We are looking for SDET to own quality engineering for the Simbian platform end-to-­end.This role is not about executing test plans handed to you. It's about building the test infrastructure, strategy, andculture that makes quality a first-class property of everything we ship.You will design and build automated test frameworks from the ground up, integrate quality gates into the releaseprocess, and define what "release-ready" means for a multi-tenant, AI-powered security platform. You'll work closelywith engineering, product, and security teams to embed testability into the platform from the start.

What You'll DoTest

Automation & Framework Ownership

• Build and own the automated test framework covering UI, API, and integration layers for a multi-tenant webplatform.
• Design and implement test suites that are reliable, maintainable, and fast enough to run in CI.
• Drive flaky-test reduction and own the health of the regression suite over time.
• Establish test patterns and tooling that engineers can build independently.
• Design the test strategy for complex platform surfaces: multi-tenancy, RBAC, self-serve upgrades, and agenticworkflows.
• Define coverage targets and release-readiness signals that the team can trust.
• Build and maintain regression suites that protect against regressions as the platform evolves rapidly.
• Identify gaps in coverage proactively and prioritize closing them based on risk.

CI/CD Integration & Quality Gates

• Integrate test suites into CI/CD pipelines, so quality checks are part of every release, not an afterthought.
• Build containerized test environments using Docker and Kubernetes to ensure consistency across dev, staging, andproduction.
• Define and enforce quality gates that block bad releases and give engineers fast, clear feedback.

Engineering Partnership & Defect Triage

• Partner with engineers early - during design and implementation - to ensure features are built for testability.
• Own defect triage: reproduce issues reliably, prioritize by impact, and track resolution.
• Contribute to architectural discussions where quality and testability are at stake.

Requirements

You Might Be a Good Fit If You

• Have 6-10 years of SDET or quality engineering experience, with a track record of building automationinfrastructure, not just writing tests.
• Think in systems: you design test strategies the way engineers design software.
• Are comfortable operating independently - defining scope, making tradeoffs, and driving execution without adetailed spec.
• Care about whether the product works for users, not just whether test coverage numbers look good.
• Enjoy debugging hard, flaky, or environment-dependent failures and turning them into reliable signal.
• Are comfortable in ambiguous, fast-moving environments where the product is changing as you test it.

Must Have

• 6-10 years of professional SDET or quality engineering experience.
• Hands-on experience with API automation (REST, GraphQL) and UI automation (Playwright, Selenium, Cypress, orequivalent).
• Experience integrating test suites into CI/CD pipelines (GitHub Actions, Jenkins, or equivalent).
• Experience with containerized test environments using Docker and Kubernetes.
• Demonstrated ability to design test strategy independently - multi-tenancy, RBAC, or similarly complex surfacespreferred.
• Strong debugging skills and ownership mindset.

Bonus / Great to Have

• Experience testing security products - SIEM, SOAR, EDR, NDR, or similar.
• Experience testing LMM-powered or agentic systems - evaluating non-deterministic outputs, hallucination edgecases, or agent behavior.
• Experience building evaluation frameworks or golden datasets for AI workflows.
• Experience with observability and tracing tools to debug test failures in distributed systems.
• Strong academic background in Computer Science or related field.
• Build quality infrastructure for an AI-first cybersecurity platform from the ground up - no inherited mess.
• Work at the intersection of AI, cybersecurity, and distributed systems.
• Own the quality bar for the entire platform - your decisions shape what ships.
• Work directly with founders, engineers, and security experts.
• Be part of an early team where your work has an outsized, visible impact.
• Ship fast, learn fast, and build systems that matter.
