QA Team Lead

About the Position

ThingsBoard is a B2B IT product company specializing in IoT solutions. Our core product, the ThingsBoard IoT platform, has grown into a robust ecosystem of standalone products and add-ons. We are looking for an experienced QA Team Lead to join our team in Kyiv, Ukraine. You will be responsible for shaping our QA strategy, strengthening test automation, and ensuring the reliability of our products as they scale. If you enjoy solving complex technical challenges and building effective QA processes, we’d love to hear from you.

Responsibilities

Strategy and People

• Shape the quality strategy for the ecosystem products - ThingsBoard On-premises, Cloud, Private Cloud, Edge, TBMQ broker, and IoT Gateway: test levels, deployment matrix, release readiness criteria.
• Lead the team: planning, test-code and test-case reviews, mentoring, hiring.
• Own the metrics: escaped defects, regression cycle time, automation coverage, flaky rate; decide what needs QA and what doesn't.

Automation (hands-on)

• Build a QA-owned automation layer over the TeamCity black-box pipeline: API, WebSocket, integration scenarios with simulators and brokers (Testcontainers, Docker Compose).
• Grow Angular UI automation: extend the Selenium/Page Object layer or make the case for Playwright.
• Raise test documentation: parameterized cases, priorities, traceability to Jira.

Releases and Regression

• Run regression for two LTS lines and patches, post-release checks on Cloud in both regions, install/upgrade, and security patch (CVE) verification.
• Test transports, integrations, and data processing: MQTT (incl. Sparkplug), CoAP, LwM2M, HTTP, SNMP, OPC-UA; LoRaWAN network servers (ChirpStack, The Things Stack, Loriot, ThingPark); cloud and broker integrations (AWS IoT, Azure IoT Hub, Kafka, RabbitMQ, Pub/Sub, Pulsar); data converters, Rule Engine, Calculated Fields, Alarm Rules.
• Triage community (GitHub Issues) and customer bugs with Support and CSM; close tenant-isolation, RBAC, SSO/2FA, and load risks.

Adjacent

• Mobile app (Flutter, iOS/Android), about 7% of test cases - you organize its testing, not run it by hand.

Requirements

• 5+ years in web/backend product QA, including 2+ years owning one product's quality across several release cycles at a product company.
• 1+ year leading a team of 3+ engineers: planning, process, metrics, reviews, hiring.
• Hands-on automation in Java. Our stack: Java (TestNG, REST Assured, Testcontainers), Selenium or Playwright for Angular.
• Deep API testing: REST, authentication (JWT, OAuth2, API keys), multi-user and multi-tenant scenarios; understanding of WebSocket.
• Service-to-service integration testing: queues/brokers (Kafka, RabbitMQ, or MQTT), webhooks, Docker environments, automated tests in CI.
• Test design and release discipline: parameterized cases, traceability to issues, regression exit criteria, upgrade-path verification.
• Understanding of load testing (Gatling, k6, JMeter, protocol simulators) and reading metrics (Prometheus/Grafana).
• Technical degree: computer science, software/computer engineering, cybersecurity, electronics, telecommunications, automation, applied mathematics, physics.
• English B2+ (docs, customers, community), fluent Ukrainian; work from our Kyiv office (Podil), flexible hours.

Nice to Have

• IoT/embedded: MQTT, CoAP, LwM2M, LoRaWAN, OPC-UA, Modbus; real devices, OTA, simulators, IoT platforms.
• Security testing: OWASP API Top 10, tenant isolation, RBAC/SSO/2FA.
• Kubernetes; PostgreSQL, Cassandra, or TimescaleDB; Redis/Valkey.
• AI tools for test generation and failure analysis; mobile testing (Appium, Flutter integration tests).
• Open-source contributions or community experience (GitHub Issues).

Key Challenges for the First Year

• 90 days: regression audit; strategy and stack agreed with CTO; first QA-owned smoke (API + MQTT/HTTP) in TeamCity on one LTS line.
• 6 months: critical LTS regression at least 50% automated; patch regression time halved.
• 12 months: integration bench with simulators and brokers in CI; critical escaped defects in Cloud measured and at least halved.

We Offer

• Work with the largest enterprise IoT deployments on the platform.
• Competitive salary plus annual performance bonuses.
• Office in Kyiv, hybrid format, flexible hours.
• An experienced team without bureaucratic overhead.
• Career growth and regular salary reviews.
• Medical insurance, complimentary English classes.
• Team-building and corporate events.
