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.

We’re looking for a Head of Engineering 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.

You will be responsible for:

• Leading the Engineering Team: Managing and developing a team of 12 engineers across backend, full-stack, and mobile development.

• Building a Strong Team: Creating an environment where engineers feel supported and heard, fostering trust and accountability, and helping the team grow and deliver results.
• Staying Hands-on When Needed: Contributing to technical tasks in critical situations, while keeping people management and team leadership as the main focus.

What you need to succeed in this role:

• Engineering Leadership: Experience leading and developing engineering teams.
• Technical Background: Strong software engineering foundation. Experience with JavaScript/TypeScript and Node.js or a Java background with readiness to adapt to another stack.
• Cloud Infrastructure: Experience with cloud infrastructure, particularly AWS.
• Scaling & Processes: Experience scaling engineering teams and improving processes in a growing business.
• Product Mindset: Ability to balance technical quality with business priorities and delivery speed.
• People Management: Ability to develop engineers, set clear expectations, and build a culture of ownership.
• Stakeholder Management: Experience working closely with the CEO and business leaders to align engineering with business goals.

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.

• Design and maintain a data architecture that balances speed and depth: fast, aggregated reporting alongside detailed, granular data for deeper analysis;

• Genuine enthusiasm and hands-on experience with AI-assisted workflows;
• Comfortable working autonomously, turning loose business goals into a concrete backlog of boards, metrics, and experiments;
• Understanding of analytics infrastructure, event tracking, and data consistency principles;
• Experience partnering closely with engineering and product teams on analytics implementation;
• Ability to structure ambiguous requests into clear analytical solutions and priorities;
• Strong communication skills and ability to work cross-functionally with different departments;

🚀 WILL BE YOUR BOOST:

• Familiarity with the Steam trading ecosystem or skins markets (CS2, Dota2, Rust);
• Domain experience in high-load e-commerce, Fintech, or iGaming projects.

🥷 YOUR POWER-UPS SOURCE:

• Spontaneous weekend from the CEO;
