Are you someone who wants to shape how integrations are done, not just follow a set script? Are you ready to take ownership of complex integrations, work with the latest technologies, and see your expertise make everyday work smoother for hundreds of colleagues and customers? If you enjoy tackling complex challenges and want to help develop a modern integration environment, you might be the Senior Integration Developer we're looking for.
What is it all about
At Staria, we're scaling up our integration capability and looking for a Senior Integration Developer to join our Data Solutions team.
We are renewing our integration architecture and rolling out a centralized iPaaS platform. We're building robust, future-proof integrations between our business-critical systems - from ERP to payroll and BI. In this role, you'll design, develop, and maintain these integrations, focusing on API-based solutions, data transformation, and reliability.
How you'll make a difference
Most of your work will focus on building new integrations and developing our integration landscape with the Frends iPaaS platform. During your first year, you'll also take part in migrating some legacy solutions to the new platform, ensuring a smooth transition for our business. You'll get to design and build integration flows hands-on and solve both technical and business challenges along the way. On a typical day, you might:
-
Design and implement integrations using REST APIs, JSON, XML, and LINQ
-
Handle error management, monitoring, and troubleshooting in production
-
Migrate legacy integrations to the new platform, ensuring business continuity
-
Collaborate with architects, system owners, and other developers, while also enjoying a high degree of independence
-
Document your work and help develop best practices
-
Take part in shaping our integration architecture and ways of working
You'll have a real impact on how integrations are built at Staria from the ground up. You'll see the results of your work quickly and get direct feedback from users and colleagues.
The practical stuff
We hope you're based in Finland, ideally in the Helsinki area and able to visit the office weekly. However, with the right candidate we're flexible: you can work remotely from anywhere in Finland, as long as you can visit Helsinki at least once a month. Staria's hybrid work model offers the best of both worlds: modern office in the heart of Helsinki, combined with the flexibility to work remotely.
Our salary range for this role is €5000-7000/month, depending on your background. The holiday bonus is distributed evenly across your monthly pay, so it's part of your regular salary.
Keys to success in this role
This role is a great fit for you if you bring:
-
Solid skills in REST, JSON, XML, XSLT, SQL, and C#/.NET (LINQ)
Experience with Azure (Functions, Service Bus, Key Vault), CI/CD, GraphQL, custom Frends tasks in C# / .NET, or high-volume integrations is a plus.
Why join us?
-
Here, growth isn't just a buzzword. You'll get real opportunities to develop your skills, take ownership, and leave your mark on how we work. You'll help build something new, see your impact and have a say in how things are done. We trust you to know what works.
-
Our hierarchy is low and the atmosphere is relaxed. We are serious about growth, but never too serious at work. Bring your whole self - personality, quirks, and all.
-
We believe in genuine connections. Regular team days, office breakfasts, and events keep our culture strong, even when everyone's not in the same place.
-
We're proud of our Great Workplace certification, because it's based on what matters most: strong teamwork, sense of purpose, managers who truly listen, and a culture where people want to stick around.
-
You'll love our Helsinki HQ: rooftop views, quality coffee, quiet spaces for focus, and a welcoming crew always ready for a chat or lunch break.
