ThingsBoard

ThingsBoard, Inc. was founded in 2016. We develop software products for IoT (Internet of Things). Our Private Cloud department runs dedicated ThingsBoard environments for 40+ enterprise customers on AWS, GCP, Azure and StackIT, including some of the largest IoT deployments on the platform.
We are looking for a technical Customer Success Manager to own our largest enterprise accounts: making sure they get value fast, their environments stay up to date, and their teams bring new use cases to production faster. This is not a sales role: pricing, contracts and renewals are handled by Sales.

Requirements:
— 4+ years in a customer-facing technical role (Technical Account Manager, Solutions Engineer, Customer Success Engineer, Implementation Engineer).
— Hands-on experience with IoT or data platforms: you have built or integrated solutions yourself.
— Good understanding of IoT protocols (MQTT, HTTP, CoAP), REST APIs and JSON.
— Scripting skills in JavaScript or Python. Basic SQL.
— Understanding of cloud infrastructure: Kubernetes, managed databases, load balancers.
— Experience working with enterprise stakeholders, from engineers to management.
— Strong English skills (C1).
— A proactive and structured approach.

Responsibilities:
— Be the main point of contact for 2 strategic enterprise customers at the start, growing to 4–6.
— Advise customer engineers on mapping use cases onto ThingsBoard: device profiles, rule chains, integrations, dashboards, alarms, multi-tenancy.
— Review customer solutions and recommend best practices for performance and scale.
— Build quick proofs of concept and examples that unblock customer teams.
— Plan and control upgrades and maintenance of customer environments together with our Reliability Engineers.
— Work on security and compliance questionnaires together with the engineering team.
— Demo new ThingsBoard features (Trendz, Edge, mobile app) and drive adoption.
— Collect customer feedback and run regular business reviews.

Key Challenges for the First Year:
1. Enterprise Account Ownership: Took ownership of 2 strategic enterprise accounts, becoming their primary point of contact and technical advisor. Retained both accounts throughout the year.
2. Customer Success & Adoption: Helped each customer bring at least one new use case into production faster through technical guidance, architecture reviews, or proof of concept (PoC) development.
3. Proactive Maintenance & Communication: Ensured 100% of planned upgrades and maintenance activities were communicated to customers at least 2 weeks in advance, with no unexpected disruptions.
4. Account Health & Business Reviews: Conducted quarterly business reviews for every account and kept CRM account health records consistently up to date.
5. Revenue Growth & Portfolio Expansion: Increased recurring revenue from these customers (plans, instances, and add-ons) by at least 6% year over year and expanded the portfolio to 4–6 enterprise accounts.

Will be a plus:
— Experience with ThingsBoard.
— German language.
— Experience with security questionnaires and enterprise procurement.

What We Offer:
— Working on an open-source IoT platform with thousands of installations globally.
— 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.

ThingsBoard is a B2B IT product company. Our core product is the ThingsBoard IoT platform, and around it we’ve built an ecosystem of standalone products and add-ons.
We deliver and constantly improve a scalable, robust, and affordable IoT ecosystem that dramatically reduces time-to-market for life-changing IoT solutions. We also help companies deliver great IoT products based on ThingsBoard.
We’ve been building the platform since 2016. Today it runs in production for over a thousand companies worldwide — in energy, manufacturing, retail, telecom, healthcare, and agriculture — and our team has grown to 100+ people in our Kyiv-based office.

We are looking for an experienced QA Lead who can combine hands-on technical expertise with team leadership and take ownership of quality across our IoT ecosystem. You will help shape our QA strategy, strengthen test automation, improve release confidence, and ensure our products remain reliable as they scale. If you enjoy solving complex technical challenges and building effective QA processes, we’d love to hear from you.

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, TypeScript or Python; 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.

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.

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).

IoT is a plus, not a must. Devices, firmware, OTA or IoT platforms on your CV speed up your start; none yet? We will teach you — simulators and a team that tests this daily are here. Not a match on every line? Apply anyway: API and integration depth and the drive to lead beat a full checklist.

What 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.
