We are looking for a
Senior Frontend Engineer
to help take Groweo® to the next level.
As a Senior Frontend Engineer, you’ll play a critical role in shaping the product experience for our customers. You’ll work closely with product designers, backend engineers, and stakeholders to deliver beautiful, performant, and scalable user interfaces. You’ll be a key voice in architectural decisions and a mentor for other frontend developers as we continue to grow our engineering team.
The role is based in our central Helsinki office, where you'll work closely with the rest of the product team. Once you get accustomed to our stack and ways of working, you can transition to a hybrid model if you want (one remote day per week). We offer a 4 day work week as a benefit, so you can have a long weekend every week.
Please note: To qualify for this position, you need to be located in Finland with working permit. We do not offer relocation or visa services at this moment.
Who You Are
You are a seasoned SaaS development professional with +5 years of experience building and maintaining production-grade web applications and proven track record in building modern web applications.
You have excellent communication skills in English, and you’re comfortable with communicating with both technical and non-technical stakeholders.
You have a strong product thinking mindset – you care not only about what we are building, but also the why. Working in an agile, fast-moving environment is familiar for you, and you already know that you excel in the constant change of a scaling SaaS company. You have a strong sense of ownership and accountability, and you demand the same from your peers and team.
