How to Apply for Senior Software Engineer - 1 year Fixed term contract

at Gropyus

🏢 About Gropyus

GROPYUS is a technology-based construction company revolutionizing the building industry by combining digitalization, prefabrication, and timber construction to create sustainable, affordable homes. Their fully digitalized processes and automated production lines make them a unique blend of tech and construction, offering a chance to work on impactful projects that address housing and sustainability challenges.

About This Role

As a Senior Software Engineer on a 1-year fixed-term contract, you will develop Kotlin services to generate 3D parametric models that drive automated production lines. You'll solve complex geometry and math challenges, build smart automation flows, and directly contribute to making high-quality, sustainable housing scalable and efficient.

💡 A Day in the Life

You'll start by reviewing automated test results from overnight builds, then join a standup with your team to discuss progress on a new parametric model feature. You might spend the afternoon coding a Kotlin service to handle a new geometry constraint, collaborating with a domain expert to validate the math, and end the day deploying a small automation improvement to CI/CD pipelines.
