Senior Frontend Engineer

If you're a Senior Frontend Engineer looking for a product with real traction, a small team where your impact matters, and the opportunity to shape how a platform scales, this could be your next move.

Groweo® builds AI-powered tools that help small and medium-sized businesses turn their websites into always-on sales, marketing and support engines. Nearly 2,000 businesses already use our platform, and we're now building a senior in-house Product and Engineering team in Helsinki to take it to the next stage.

Why join now?

This isn't a maintenance role or a position in a large, established engineering organisation. You'll join as one of the first senior engineers in our Helsinki core team and help shape both the product and how we build it.

You'll have the opportunity to influence:

• Our frontend foundations (how we look, feel, function etc.), design system and component library

• The end-to-end user experience by creating beautiful, user friendly, animations

• Technical standards and ways of working

• How we build intuitive, high-quality experiences around AI

• The engineering culture as the team grows

We have product-market fit, nearly 2,000 customers and international ambitions. Now we want to make the product ready for the next stage of growth.

What you'll work on

You'll build and evolve user experiences across Groweo's products using React and TypeScript, working closely with Product, Design and Backend Engineering.

Your work will include:

• Building conversational AI interfaces, dashboards that visualize complex data beautifully, and interaction patterns that feel intuitive

• Creating scalable frontend architecture, reusable components and design systems

• Turning concepts into polished, performant and accessible experiences

• Owning features end-to-end, from understanding the user problem to production

• Improving frontend performance, testing and development practices

• Helping define technical standards for the engineers who join after you

You'll work with products handling large amounts of interaction data, real-time AI experiences and multiple product suites as we scale.

Who we're looking for

We're looking for an experienced frontend engineer who combines strong technical skills with product thinking.

You'll likely have:

• 5-7+ years of experience building beautiful, interactive frontends

• Deep experience with React and TypeScript

• Strong understanding of component architecture and modern frontend development

• The ability to take an ambiguous problem, shape the solution and drive it forward

• A strong eye for UX and attention to detail, as well as experience with motion and animations

• Professional proficiency in English

• Working with a SaaS product in a scale-up or startup environment isn’t required, but can be considered a plus

You need to be based in the Helsinki capital region and have a valid work permit for Finland. We don't currently offer relocation or visa sponsorship.

What we offer

• 5,000–6,500 euros/month, depending on your experience

• One paid day off each week (Monday or Friday)

• Helsinki city-centre office

• On-site collaboration during onboarding, followed by the option of 1 remote day per week

• Lunch benefit on top of salary

• Comprehensive health coverage for work and leisure

• HSL public transport season ticket

• Employee perks program
