The role :We are hiring a Head of Quality Assurance to own quality across everything Delta6Labs ships. You will lead an established QA organisation of 15+ engineers embedded across product squads, and you will report directly to the CTO / VP Engineering & Product Development as part of the engineering leadership team.Qualification :B.E. / B.Tech / M.C.A. in Computer Science, Engineering or a related discipline. Equivalent practical experience considered.What you will own :Quality strategy and accountability :- Own the end-to-end quality strategy for all Delta6Labs platforms - exchanges, wallets, trading systems, and white-label deployments and translate it into a roadmap with clear quarterly outcomes.- Define and enforce release-readiness criteria, entry and exit gates, and go/no-go authority. Be the person accountable for saying 'not yet' and for making that call defensible with evidence.- Establish a risk-based test strategy that concentrates effort where financial, regulatory and reputational exposure is highest, rather than spreading coverage evenly and thinly.- Partner with Product, Engineering, DevSecOps and Security so quality is designed in from requirements through to production monitoring.Test automation and quality engineering :- Own the design and evolution of our automation frameworks across API, service, integration, data and UI layers, with a deliberate bias toward API and contract-level coverage.- Drive automated regression suites into CI/CD so that every merge and every release candidate is gated on evidence, not opinion.- Build and own performance, load, soak and stress testing for high-throughput, low-latency paths, order matching, market-data streams, settlement batches and webhook fan-out.- Establish contract testing between services, service virtualisation for third-party dependencies (custody, KYC/AML, blockchain analytics, market data), and dependable test-data management across environments.- Drive data-integrity and reconciliation testing across ledgers, balances, fee calculations and transaction histories, down to database level.- Partner with Security and DevSecOps on security regression, dependency and configuration checks.- Champion shift-left practices: testability reviews at design time, unit and integration coverage standards, static analysis, feature flags,



and safe progressive rollout.Team leadership and development :- Lead, coach and grow a QA organisation of 8+ engineers; set clear ownership boundaries between squad embedded QA and a central quality-engineering function.- Own hiring end to end - define the bar, build the interview loop, and recruit manual, automation and SDET talent in a competitive Delhi NCR market.- Define career ladders, competency frameworks, goal setting and performance reviews for the QA function; create a real path that converts robust manual testers into automation engineers.- Build a culture of engineering rigour and psychological safety, where defects are data, blameless root-cause analysis is routine, and escalation is expected rather than penalised.- Act as the senior quality voice with clients and stakeholders - in delivery reviews, pre-sales technical conversations, and audit or security-review requests for quality evidence.Process, metrics and continuous improvement :- Define the defect lifecycle, severity and priority taxonomy, triage cadence and response SLAs - and hold the whole engineering organisation to them.- Instrument quality and report it on a fixed cadence: escaped-defect rate, defect density, automation coverage and stability, flake rate, mean time to detect and recover, regression cycle time, and release-failure rate.- Run structured root-cause analysis on production incidents and close every loop with permanent test coverage.- Rationalise tooling, environments and test infrastructure against cost and value, including provisioning, device and browser farms, and licensing.- Maintain the traceability and documentation trail that our ISO obligations, client audits and security reviews depend on.What you must bring :- 10+ years in software quality assurance, including 4+ years leading QA teams, with direct experience managing a team of eight or more engineers.- Demonstrated ownership of quality for a production financial, payments,



trading or otherwise high transaction-volume platform.- Deep, hands-on API and backend testing expertise : REST and WebSocket, authentication and authorisation flows, pagination and rate limiting, idempotency, error contracts, and database-level validation with confident SQL.- A real automation engineering background - you have built or substantially rebuilt a framework yourself, not only sponsored one. Strong in at least one of Python, JavaScript/TypeScript or Java, with tools such as pytest, Playwright, REST Assured, Postman/Newman or equivalents.- Proven ownership of performance and load testing using k6, JMeter, Gatling, Locust or similar - including interpreting results and driving fixes alongside engineers.- Experience testing microservices and event-driven systems, including Kafka or RabbitMQ-style messaging.- A track record of hiring, mentoring and retaining QA engineers, with specific people whose growth you can point to.- Excellent written and verbal communication, able to hold a technical position with senior engineers and to explain risk plainly to non-technical stakeholders and clients.- Experience as Head of QA in at least one of the following : a cryptocurrency exchange, a high-frequency trading (HFT) environment, or core trading systems such as matching engines, order books, order management and trade settlement.Nice to have :- Direct experience with cryptocurrency exchanges, digital-asset custody or trading systems, order books, matching engines, market data, liquidity and settlement.- Familiarity with custody and wallet infrastructure (for example Fireblocks), KYC/AML vendors (SumSub, Veriff) and blockchain analytics (Chainalysis).- Exposure to blockchain and smart-contract testing concepts, testnets, and coordinating external audits.- Experience in a multi-tenant or white-label delivery model with client-specific configuration and parallel release trains.- Working knowledge of security testing fundamentals and fintech-relevant standards - OWASP, PCI-DSS, SOC 2, ISO 27001.- Prior experience in an organisation delivering both product and client services, where quality is contractually visible.- Relevant certifications (ISTQB Advanced Level, CSTE) - welcome, though never a substitute for demonstrated work.
