Senior Software Developer
Would you like to help modernize a large enterprise software system and influence its future?
We are looking for a senior-level software developer to join us in maintaining, developing and renewing the Misonet software. Misonet is Mipros SCADA system for the water and energy business line. It has been built over the years and deployed to dozens of industrial customers, and it will remain the flagship product of the company in the future. Thats why its development combines understanding legacy systems with utilizing modern technologies.
Misonet is now being systematically developed towards more modern architecture and technology. The work includes improving usability and the user interface as well as carrying out larger refactoring that gradually modernize the software.
In this role, you will have the opportunity to influence technical solutions, make decisions, and develop the system in a long-term, sustainable way. There is also the possibility of growing into a Product Owner role for Misonet in the future.
The position requires a valid right to work in Finland.
What the job includes
Development of Misonet is diverse and varied. The work may include, for example:
- improving the user interface and usability
- implementing new features to meet project needs
- analyzing and refactoring legacy code
- gradually modernizing the software
- documenting work in Confluence
The release cycle is approximately every six months, allowing time to focus on high-quality development work and larger improvements.
Technologies
The current Misonet technology stack includes:
Backend
- Java
Frontend
- HTML
- JavaScript
- CSS
- jQuery
In addition, expertise in databases (e.g. Postgres), networks (e.g. MQTT), on-premises deployment, configuration, monitoring, interest in cybersecurity for industrial automation, and modern Java (e.g. Quarkus) would be beneficial in this role.
The codebase is extensive and has evolved over different technological eras, so the work requires curiosity, patience, problem solving, and a desire to deeply understand the system.
What we expect from you
We are looking for a software engineer who enjoys working on diverse system development and wants to influence the direction of the software.
We hope you have:
- more than 5 years of experience in software development
- experience working with legacy software
- understanding of modern software technologies
- the ability to make technical decisions and drive development forward
- interest in both backend and frontend development
- strong collaboration skills
This role is not purely frontend or backend focused, but rather suited for a software engineer who wants to understand how an entire system works.
In this role you will
- modernize a real production system
- work with a large and technically diverse software base
- influence technical solutions
- develop the system with a long-term perspective
- collaborate with different expert teams across the company
- potentially grow into a Product Owner role in the future
The role includes a partial remote work option, and especially at the beginning of the employment, it is important to be on site at our office in Mikkeli for an agreed period of time to become familiar with the role.
