Customer Success Manager

Onomondo is on a mission to revolutionize global IoT connectivity. We’re here to redefine how connected devices communicate and we need great people to help us push the boundaries of what’s possible.

Are you passionate about helping customers thrive in the Internet of Things (IoT) space? Do you enjoy combining problem-solving, technology, and relationship-building? If so, we’d love to hear from you!

At Onomondo, we’re on a mission to simplify global IoT connectivity. We’ve raised a €21M Series A and built a cloud-native connectivity platform that gives companies full control of their IoT deployments—from anywhere, at any scale.

We're growing fast and looking for a Customer Success Manager to help our customers succeed as we expand.

About the role:

As a Customer Success Manager, you’ll play a pivotal role in ensuring our customers get the most out of the Onomondo platform. You’ll be their trusted advisor—guiding them through onboarding, feature adoption, and long-term success, while also acting as their internal advocate.

You'll manage a portfolio of customers across different industries, proactively helping them unlock value, solve challenges, and grow with us. You’ll also have the autonomy to lead initiatives that align with your interests and strengths to support the customer journey.

Key responsibilities:

• Build and nurture strong, lasting relationships with customers in your portfolio.

• Act as the primary point of contact, providing expert guidance, support, and a human touch.

• Onboard new customers and ensure a seamless implementation of our SIM management platform.

• Host product demos and workshops to help customers use features effectively.

• Conduct regular check-ins to understand success metrics, gather feedback, and identify expansion opportunities.

• Analyze customer usage data to identify trends and proactively recommend improvements.

• Collaborate cross-functionally with Product, Sales, and Growth teams to drive a seamless customer experience.

• Share customer insights to help shape future product development.

About you:

We’re not looking for a checklist of credentials, we’re looking for people who are curious, adaptable, and has a customer-first mindset. You might resonate with some of the following:

• You have a couple of years of experience in a customer-facing role. Perhaps in customer support, customer success, or customer operations, ideally within a scale-up environment.

• You have a degree in business, engineering, communications, or another relevant field, but we value practical experience just as much.

• You’re a strong communicator in English (written and spoken) and enjoy working with people from diverse backgrounds.

• You’re a natural problem-solver who loves learning, especially about tech.

• You can work independently but thrive in a collaborative team.

• You’re comfortable with multitasking and managing competing priorities.

• You’re excited to get into the technical details of our product and the infrastructure we support.

• Bonus points if you’ve worked with SaaS tools or CRM systems (e.g. Hubspot), but this is not a must.

• You’re based in Copenhagen and able to work from our HQ (with flexibility).
