What should you know about SKELAR? It's a venture builder — in other words, a company that builds companies. Together with founders, we create consumer businesses that become leaders in global markets across EdTech, Mental Health, Petcare, FashionTech, and beyond.

Our teams build tech products that win recognition from Product Hunt and The Webby Awards, earn thousands of glowing Trustpilot reviews, and reach over 10 million users worldwide. That kind of impact doesn't happen by accident — it starts with exceptional people, and our people are our top priority.

We've built an environment where expertise meets opportunity, and where there's no ceiling on what you can achieve. Now we're looking for the kind of people who don't just want a job — they want a challenge.

Right now, we’re looking for a Frontend Engineer who will help lead one of the key marketing streams on Meta for our partner company, Duomo.

Duomo is an app rooted in Christian values, helping people turn Scripture into daily habits and inner peace. We’re building a leading Christian-tech product for people seeking spiritual renewal.

What you will be responsible for:

• Developing and maintaining scalable frontend applications using React, TypeScript, and Next.js;

• Building and evolving an admin panel for managing content on our product application;

• Integrating frontend solutions with backend services and REST APIs;

• Optimizing application performance, reliability, and overall frontend architecture;

• Writing and maintaining unit, integration, and end-to-end tests;

• Supporting CI/CD pipelines and frontend engineering best practices;

• Participating in technical decision-making, code reviews, and improving developer experience.

What you need to succeed in this role:

• 2+ years of commercial experience with React and TypeScript;

• Strong understanding of SSR/SSG concepts and hands-on experience with Next.js (or similar frameworks);

• Experience working with REST APIs, including async flows, error handling, and caching;

• Hands-on experience with client-side and server-side state management solutions (Redux Toolkit, TanStack Query, or similar);

• Understanding of frontend performance optimization techniques such as lazy loading, memoization, and code splitting;

• Experience writing and maintaining unit, integration, and E2E tests using Vitest, Testing Library, and Playwright;

• Familiarity with CI/CD workflows, Git-based collaboration, and code review practices;

• Experience with Sentry (or similar monitoring tools) and a solid understanding of frontend architecture principles.

Nice to have:

• Experience with Node.js (NestJS/Express);

• Experience with PostgreSQL and ORMs such as Prisma or Drizzle;

• Basic familiarity with AWS infrastructure;

• Understanding of web security best practices.

Why Duomo

— You’ll work on a product with a clear mission and real values.
— You’ll help us transition from a content-rich app into a truly connected spiritual platform.
— You’ll be early enough to influence how product is done at Duomo long-term.

What we offer:

— Competitive salary;
— Significant impact on a rapidly growing business and contribution to how it shapes up;
— Ample career opportunities for ambitious growth and development;
— A possibility to attend internal, external courses, seminars and the access to a corporate library;
— Comfortable working environment. We provide all necessary work equipment for your role and serve complimentary breakfasts, lunches, and snacks in the office;
— 20 days of paid vacation, medical insurance and a variety of sports activities available for employees inside and outside the office.

At SKELAR, we've built an environment where people can grow, build, and do the most meaningful work of their careers:

• SKELAR Platform. The operational backbone of our venture builder. It exists to help founders move faster and easier — so business teams can stay laser-focused on the product while 10+ specialized Platform takes care of everything else: Legal, Finance, HR, Admin, Talent Acquisition, Employer Branding, IT, and more.

• Networking and knowledge-sharing as a way of life. Our people include co-founders who've launched multiple businesses and some of the sharpest specialists in the industry. Whatever expertise you need, it's never far away.

• Learning programs you won't find anywhere else. We've developed our own educational tracks for teammates to choose from — a two-month school for first-time managers, intensive AI workshops, and professional clubs for engineers, product managers, and more.

• Meaningful impact in Ukraine. The SKELAR Foundation was created by our own people, and every employee plays a part in bringing important social initiatives to life. We founded Europe's first accelerator for veterans and are working to build lasting support structures for veterans at a national scale.

• Spaces designed to inspire. Our offices are places people actually want to be — with an in-house gym, a climbing wall, Bali-inspired green spaces, and libraries. Every detail, from service and security to comfort and design, is built to match the pace of our growing teams.

• Everyday comfort built in. Meals, gym access in Kyiv or a partial fitness stipend in Warsaw, health insurance, paid business travel where the role requires it, and corporate partner discounts.

We'd love to tell you more in person.
