Software Developer (Application development)
NAPA Design Solutions offers a comprehensive solution for 3D ship modeling and design tools covering hull form design and hydrodynamics, hydrostatics and stability, structural design, and information sharing across the shipbuilding process. These are among the most powerful tools in the industry, trusted by the world's largest shipyards and classification societies.
The role: what is it about?
The team is now looking for a Software Developer who will focus on application usability development with .NET, C#, WPF and XAML. Development, testing, and maintenance of the NAPA ship design solutions are part of your daily work. In this role you will mainly work on developing NAPA Engineer, a modern design and computing platform for naval architects. It combines trusted NAPA calculation capabilities with a redesigned, intuitive user experience and a powerful visual approach to engineering workflows.

You will do this work with artificial intelligence (AI) as a normal part of your toolchain. We use agentic coding capability across our development teams, which means using AI coding agents to plan, write, test, review and refactor code, and doing it in a way that improves both delivery speed and code quality. We expect you to use these tools in your daily work, to help us learn where they work well and where they do not, and to share those learnings with your team.
You will be working with Windows desktop applications, native libraries, third-party components, including a 3D graphics library, database engines, a licensing solution, and more.
This job is permanent and full-time.
Your team and job location
You will work in an international team where your closest colleagues are experienced software developers and naval architectural domain experts who will support you in your role. You will also interact with local and global colleagues from various teams in software development, UX design, DevOps, and sales. Together with them you will also shape how we use AI coding agents in practice, from tooling choices to review practices.
Our office is located in Helsinki (Ruoholahti), and you can work at the office or in hybrid mode. We hope to meet you at our Helsinki office regularly.
What are we looking for?
What matters most: you're curious about UI development, energized by AI-assisted development tools, and hungry to solve real problems as a self-starter. If the visual side of UI excites you too, that's a big plus.
Our ideal candidate would have:
Academic degree in a relevant field such as computer science, mathematics, physics, naval architecture, or engineering
Completed basic studies and/or having a good understanding of algorithms, data structures, and OOP (object-oriented programming)
2+ years of experience in building native Windows desktop applications
Experience in UI design
Experience using WPF, C#, and XAML
Understanding of user experience and the ability to apply it in your own design work
Hands-on experience of using AI coding assistants or coding agents in real development work, together with the judgment to review, test and take responsibility for what they produce
Interest in NAPA’s domain (maritime business)
Additionally, the following skills would be considered an advantage:
Experience with agentic coding workflows
Knowledge or studies in usability
Experience with database solutions
Experience in automated testing methods
Knowledge of software reliability and maintainability
Experience in CAD or CAE applications
You do not need to tick every box on these lists. If this role feels like a good fit for you and you have most of what we are looking for, we hope you will apply.
We work in English across all our offices, so you need to be comfortable using it in your daily work, both in writing and in conversation.
Why you will enjoy working in this role
You get to combine modern desktop application development on a next-generation engineering platform, combined with AI agentic development that we are scaling across the company
The design work of the world's largest shipyards and classification societies happens in the software you develop
Great colleagues with expertise in, for example, naval architecture, software development and UX design
A global team of 230 experts who support you and share what they know
