QA Engineer
Bengaluru
About H2Loop
H2LooP.ai is building next-generation sovereign coding models and context platforms for system engineers across embedded systems, robotics, UAV, avionics, automotive, consumer electronics, and industrial IoT.
Our core team comes from Google, Toshiba, Cisco, Bosch, Philips, and NXP.
As a Founding Engineer, you won’t just write firmware ,you will bridge real hardware with AI-driven engineering workflows and help define how future system engineers build software.
You'll be our first QA hire, working in-person with the engineering team in our Bangalore office.
What you'll own
Test infrastructure
Build and maintain automated test suites across our Python backend services
Integrate tests into CI as mandatory PR gates
Own the test pyramid: unit tests for service logic, integration tests against real infrastructure, E2E tests as a release gate before production promotion
API & backend testing
Test the core REST API across auth, org and workspace management, data sources, query/retrieval, inference, jobs, and billing surfaces
Test async workflows — background ingestion jobs, status polling, lifecycle edge cases
Test RBAC: role hierarchy, org and workspace membership, permission boundaries
AI / retrieval quality testing
Build an evaluation harness for retrieval quality — the platform's core value is citation-accurate answers over indexed repos and datasheets; this needs repeatable benchmarks, not manual spot-checking
Test ingestion output correctness across the artifact formats produced by the pipeline
Regression-test LLM routing — model selection, per-user budget enforcement, token tracking
Frontend & client testing
Test the web UI: auth flows, workspace and data source management, query and chat surfaces
Test the IDE extension and CLI agent: key user flows, error handling, session persistence
Cross-browser baseline and basic accessibility
Multi-environment & release gates
Own the preprod QA gate: validate each release candidate before it promotes to production
Regression test the on-prem enterprise deployment on each release cycle
Maintain environment-specific test configs across dev, preprod, prod, and on-prem targets
Required experience
3+ years in a QA / SDET role, with time at an early-stage company where you built test infrastructure rather than inherited it
Python testing — comfortable with a framework like pytest; can read and reason about service code
REST API testing — auth flows (JWT, OAuth2), async job polling, edge case coverage
CI integration — writing tests that run reliably in automated pipelines, managing test environments and secrets
Clear thinking about test strategy: what to automate vs. not, where to draw the unit/integration/E2E boundary
Strong-to-have
Experience evaluating AI/LLM output quality — retrieval benchmarks, answer correctness scoring, regression detection for non-deterministic systems
Frontend and E2E testing — browser automation tools (Playwright, Cypress, or similar), component testing
IDE extension or CLI tool testing
Database and async queue debugging — tracing a failing job through the system end-to-end
Multi-environment testing discipline across dev, preprod, prod, and on-prem targets
Familiarity with embedded systems or safety-critical software domains — our customers work in those contexts and their quality bar is high
What we don't need
Someone who writes test plans in Confluence and files bugs in Jira. We need someone who codes, runs their own investigations, and closes the loop with engineers directly. The role is more SDET than traditional QA.
Compensation & logistics
Competitive early-stage equity + salary
In-person, Bangalore office
Small team — direct access to founders and engineering
