Enterprise Customer Success Manager (Technical)

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.
