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.

Our work directly impacts millions of devices globally, ensuring seamless, low-latency, and highly available connectivity for mission-critical applications. Our services enable secure authentication, signalling, and messaging for devices using Onomondo SIM cards, across 680+ networks in 180+ countries.

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.

What You’ll Be Doing


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).

Why join Onomondo?

We’re not just building another connectivity layer – we’re reimagining how global IoT connectivity works from the ground up. With customers like Maersk and global use cases across industries, we’re tackling problems that have never been solved before.

You will experience:

  • A playful, ambitious culture where people are trusted to do what they do best

  • A beautiful 2000 sqm office in Islands Brygge with catered lunch, snacks, and drinks.

  • Flexibility to work from home, summer houses, or anywhere with good Wi-Fi.

  • A team that’s small, sharp, and all-in on shipping meaningful things fast, with room for your voice and fingerprints on what we build.

  • Legendary lunches, snack heaven, and events that actually bring people together

  • A welcoming, international team with 30+ nationalities who love building, laughing, and learning together.

  • Regular team workouts during office hours to support mental and physical wellness.

Our hiring process

We care deeply about creating a fair and inclusive process.

That means:

  • We don’t need your picture or cover letter - just your CV

  • We select candidates based on skills and relevant work experience for the role.

We’re fast but thoughtful - our goal is to ensure you feel informed, respected, and excited throughout the journey.

  • Online Interview with our Head of Customer Success, Benedicte (1 hour)

  • In-Person Interview at our HQ. Culture Interview (1 hour)

  • Final stage - Meet with our Co-Founder, Michael Karlsen and our CCO, Jillian Falconi
