At SuperOffice, we help companies build stronger relationships with customers; through tools, technology and experiences that make work feel smoother, smarter, and more meaningful. With over 30 years in the CRM space, we’re growing fast, innovating boldly and bringing new ideas to life. Now, we’re looking for a Senior Software Engineer to join our Integrations team in Vilnius.

⚙️ Be part of the team that connects it all.

The SuperOffice Integrations team is where systems, tools, and business logic come together. It’s where we turn complexity into clarity, and where seamless user experience matters just as much as strong architecture.

Here, you’ll get to work with the latest technologies alongside committed, knowledgeable, and creative colleagues. Because we build in-house, you’ll have the chance to go deep; developing real specialization across multiple integration products and shaping how customers experience SuperOffice across platforms.

💼 Your role:

As a Senior Software Engineer in our Integrations team, you will play a key role in how SuperOffice connects with the world around it. In practice, that means you will:

• Develop new features and services across multiple integration products.

• Lead performance optimization, ensuring our systems stay fast, scalable, and reliable.

• Take ownership of testing and debugging, raising the bar for code quality and stability.

• Create future-proof designs that support long-term growth and product evolution.

• Contribute to clear useful documentation that makes integration work easy to understand and maintain.

• Mentor and support junior developers, helping them grow through guidance, feedback, and knowledge sharing.

• Take part in shaping system and application architecture for new and existing products.

• Drive continuous improvement; not only in our codebase, but in how we collaborate, build and deliver as a team.

⭐️ Your Superpowers:

We believe great engineers are shaped by their mindset just as much as by their skills. We’re looking for someone who is curious, engaged, and eager to build products people love.

• Minimum of 5 years of experience building software at scale.

• Strong development skills in C# and .NET 8+.

• Skilled in front-end development with React or Angular using TypeScript.

• Comfortable working with, and setting up, CI/CD pipelines.

• Experience with cloud-native development and cloud technologies (Azure is a big plus).

• A passion for clean, maintainable code and solid engineering principles.

• Ability to break down complex problems and translate them into smart solutions.

• A collaborative spirit- you enjoy learning from others and helping them grow.

• Bachelors in IT or Computer Science. Cherry on top? AZ-204 certification.

• Excellent communication skills.

🤝 What We Offer:

• A dynamic and collaborative work environment in the tech industry.

• Your very own passport to Superland (our in-house nation with a constitution, flag, and, of course, passports).

• 16 hours off per year for team and individual volunteering.

• Travel and health insurance.

• A fun and social office, with regular team building, employee events and parties. We also have massage chairs, table tennis and chess in the office.

• 4 days per year dedicated to self-study and skill development and 5 extra vacation days after 5 years (3 in your 3rd year and 2 more in your 5th year)

• Whether you're commuting by train, bus, or tram, SuperOffice provides support for public transportation costs, tailored to individual circumstances.

• Competitive salary and benefits package, 5000 – 6500 euros gross.
