Job Summary

Ciklum is looking for a Senior Automation QA (JS) Engineer to join our team full-time in India.

As a Senior Automation QA (JS) Engineer, become a part of a cross-functional development team engineering experiences of tomorrow.

Responsibilities

- Design, build, and maintain automated test suites for the platform, Frontend and Backend, including contract tests that protect the agent-developer experience as the SDK evolves
- Build automated tests for long-running Temporal workflows including failure injection (worker kill, provider outage, retry storms) to verify durable-execution guarantees such as zero lost runs and correct compensation/saga behavior
- Automate multi-tenant isolation verification cross-tenant data access, configuration bleed, and cost-attribution correctness executed per release as a platform acceptance criterion
- Verify agent execution sandboxing and egress controls through negative testing of disallowed tool calls and network destinations
- Design test strategies for LLM-driven behavior: statistical assertions over repeated runs (pass^k consistency), semantic-similarity scoring, confidence-threshold validation, and flakiness quarantine that distinguishes model variance from genuine regression
- Build and continuously extend adversarial test corpora document-borne prompt injection in lease PDFs, tool-call hijack, and data-exfiltration probes aligned to OWASP LLM Top 10 and recognized red-team taxonomies
- Verify Human-in-the-Loop (HITL) escalation behavior confidence thresholds fire correctly and no gated/irreversible action completes without authorization
- Partner with the evaluation function on golden-dataset-driven checks, contributing test infrastructure, synthetic-data (synthetic lease) pipelines, and CI integration that make agent quality measurable and repeatable
- Automate verification of platform NFRs invocation overhead (p95), concurrency targets, queue backpressure behavior, and LLM provider failover time and surface trends per release




- Use tracing data (Langfuse / OpenTelemetry spans) as a first-class test asset: assert on trace completeness, token/cost-accounting accuracy, and alerting behavior for anomalous runs
- Wire test suites into CI/CD as hard release gates with automated, per-metric regression flagging on pull requests
- Produce auditable, reproducible test-evidence packs that feed directly into client milestone sign-off
- Embed with AI and platform engineers from the design stage making acceptance criteria, testability, and observability inputs to architecture, not afterthoughts
- Maintain test environments, mocked LLM/provider layers, and synthetic data generators that keep test runs fast, deterministic where possible, and affordable
- Mentor mid-level QA engineers, codify AI testing patterns into reusable internal frameworks, and contribute to Ciklums quality engineering practice and AI Academy

Requirements

- 8+ years of test automation with API testing, and building test frameworks other engineers adopt, not just test cases
- Hands-on experience testing LLM-powered or other non-deterministic systems statistical assertions, semantic scoring, and managing model variance (this is the differentiator; cite real examples)
- Experience testing asynchronous, event-driven systems failure injection, idempotency verification, eventual-consistency assertions; Temporal or a similar workflow engine a strong plus
- Strong CI/CD integration skills (GitHub Actions or equivalent) and the discipline to design release gates




- Solid SQL and data-validation skills; comfort building synthetic test-data pipelines and measuring dataset quality
- A security-testing and adversarial mindset; familiarity with prompt-injection techniques or a strong AppSec testing background with willingness to specialize fast
- Demonstrated judgment on what "tested enough" means under milestone pressure, and the ability to defend quality evidence to non-engineering stakeholders
- Strong proficiency in Playwright and TypeScript is mandatory for building automated test suites
- QA Automation Core: Extensive experience in building automated test frameworks (Playwright/Typescript-based) and integrating them into high-security CI/CD pipelines
- AI/LLM Literacy: Deep understanding of Large Language Model behaviors, prompt sensitivity, and the common failure modes of RAG (Retrieval-Augmented Generation) systems
- Analytical Mindset: Robust capability in statistical analysis to interpret evaluation scores and provide actionable feedback to AI Engineers for prompt tuning

Desirable

- Performance/load tooling (k6, Locust) for concurrency and latency NFR verification
- Prior testing of multi-tenant SaaS isolation
- Exposure to eval/observability stacks (Langfuse, LangSmith, Promptfoo, DeepEval, Arize Phoenix)
- Compliance evidence experience (SOC 2, GDPR) or accessibility testing (Section 508 / WCAG)
- Familiarity with Commercial Real Estate workflows (lease accounting, CAM reconciliation) or document-extraction systems (OCR, layout parsing)
- Experience using LLMs to generate test cases, adversarial payloads, or synthetic documents
- Performance Testing: Experience testing high-concurrency background processing within agentic systems
- Experience with qTest for test management
