About Exeon

Exeon is a Swiss cyber security company based in Zurich. Since 2016, we have been protecting critical infrastructures, financial institutions and enterprises whose operations fully rely on IT through AI-powered analysis of network communication. This makes the most sophisticated cyberattacks visible – attacks conventional tools fail to detect. We combine Swiss excellence with a flexible, remote-first, and collaborative culture, supporting passionate, ambitious professionals devoted to solving cybersecurity challenges and driving continuous innovation.

What your impact will be like:

As senior Scala developer, you will be a core member of our backend guild and thus closely collaborate with the Exeon DEV team, jointly developing new features for our main NDR product. You will navigate general architecture decisions for new features and drive our continuous effort to improve upon our existing code base. You will work both hands-on on the implementation as well as define and refine architectural concepts for the whole team to allow for more easily maintainable and adaptable code in the future.

In particular, you will:

• Guide the backend team on architectural questions, both for new features and old code to be refactored

• Mentor backend team members on growth paths

• Actively develop our backend code and have an impact on not only the GUI of our NDR tool, but also on our analytics backend.

• Work closely together with the DEV team to develop new features, ensuring the continued success of Exeon.NDR.

What you can expect from us:

Exeon offers an open company culture that values and encourages diversity, teamwork and a growth mindset. Our goal is to provide our employees with an exciting, supportive and motivating environment for personal growth and career development while ensuring that our team maintains a healthy work-life balance. We strive to achieve this by offering:

• Value-Driven Culture: Work guided by our Exeon values (proactive problem-solving, curiosity, ambition, ownership, transparency and care for each other)

• Continuous Personal Growth: Benefit from our annual training budget dedicated to your professional development.

• Truly International Team: Join colleagues from diverse backgrounds across the globe.

• Company Events & Workshops: Connect with colleagues through regular team events and collaborative workshops.

• Remote‑First & Flexible Work: Enjoy remote‑first culture with hybrid options (office in Zürich) when it fits best.

• Family-Friendly Options: Part-time roles & enhanced maternity and paternity leave.

What makes a good person-job-fit:

We are looking for a proactive, self-motivated and enthusiastic individual who’s comfortable in a high-paced scale-up environment and who shares our values. In addition, we are looking for certain requirements and skills to establish a good person-job-fit:

• You have 8+ years of professional experience in software engineering

• Open, reliable and collaborative professional who enjoys working in teams and can take ownership over individual projects

• Interest and passion for cybersecurity and the culture of a fast-growing scale-up culture

• Strong Scala coding skills , with a knack for architectural topics

• You can write code that is readable, well-structured and performant.

• Writing code together with tests comes natural to you. You know what degree of coverage with unit-tests and integration-tests will create quality code

• You understand complex code and are able to break tasks down into easily digestible pieces, both for new features as well as refactoring tasks

• Being neither an absolute perfectionist nor a minimalist, you know the perfect compromise between the two. You deliver outstanding code without rewriting everything from scratch, but covering all the necessary details

• You have strong communication skills. You can grasp concepts explained to you easily and are able to convey your own thoughts effectively and efficiently.

• You are fluent in English. If you speak German as well, even better.
