Software Engineer

Are you a curious developer who loves exploring new territory and has the drive to figure things out? Do you bring a can-do attitude to everything you touch and care deeply about the quality of what you ship? And do you dream of a role with real impact?

If so, we'd love to hear from you!

About Penneo

At Penneo, we build technology that helps businesses operate with trust in an increasingly complex world. What started as a digital signing solution in Copenhagen has grown into secure, compliant workflows used across Europe. With new forms of tech- and AI-driven fraud emerging fast, our mission to protect the integrity of digital business is more important than ever.

Penneo is a Certified Trusted Service Provider - we were the very first private company in Denmark to achieve this certification. That means we're not just another SaaS company. We operate critical digital trust infrastructure under the eIDAS regulation, building products that businesses across Europe rely on for identity, signatures, secure data handling, and compliance.

Your role & impact

You'll be joining a small, tightly-knit team working on our new Collect platform - a brand new platform built with the latest technologies. The team consists of three experienced senior developers (who are genuinely committed to mentoring), a designer, and a product manager. It's a space where your opinion matters, the hierarchy is flat, and you'll own your work from day one.

In a typical week you'll:

• Develop new features requested by the Product Manager.
• Fix bugs promptly - including production issues.
• Handle the full development lifecycle end-to-end.
• Collaborate directly with many different stakeholders, including: developers, PMs, and engineering teams.
• Take on DevOps tasks like deployments, monitoring, and scaling.

We hire for attitude and curiosity first. You don't need to check every box - we're looking for someone who is eager to learn, willing to stretch, and isn't afraid of new technology. That said, here's what we imagine you bring:

Must-haves

• Curiosity: a genuine drive to learn and explore new technologies, including AI.
• Backend development experience (academic projects absolutely count).
• Willingness to work across different languages and frameworks: no language zealots here.
• Attention to detail and a habit of testing your own work.
• Good communication skills: you'll interact with many different stakeholders including developers, PMs, and designers.
• Proactivity: you spot problems and act on them without waiting to be asked.

• Experience with Kotlin (our backend language of choice).
• A degree in computer science or a related field - helpful, but not required.
• Familiarity with DevOps practices (CI/CD, monitoring, Docker/Kubernetes).

Joining Penneo means joining a team that genuinely cares - about the product, about each other, and about your growth. You’ll work alongside highly skilled developers who love sharing what they know and coaching the people around them. Knowledge flows freely here, and you’ll grow fast.

On the technical side, you’ll be working on infrastructure that very few companies are building, using the newest technologies and actively exploring what’s next - including AI.

We manage the full development lifecycle ourselves, which means you’ll see your work go from idea to production, and your perspective will shape how we build.

Beyond the work itself, we think where and how you spend your day matters too. Here’s a taste of what life at Penneo looks like:

• Flat hierarchy: great inputs are equally valued regardless of title or tenure, and your voice genuinely matters.
• A Culture Club that keeps things fun: social events, activities, and a team that genuinely enjoys spending time together.
• Probably the best lunch in town, great coffee, and a gym on-site: because the little things add up.
• Cross-company collaboration: you’ll connect with talented people across the entire organization.

Curious? So are we. Don’t wait - apply now!
