Senior / Tech Lead Mobile Engineer - Bravel

Join Us At Skelar

Once someone built Duolingo from scratch. Someone wrote the first line of code, created the first lesson, found the first user. We are now here, launching a new business within the venture builder Skelar.

In the world, over 1.8 billion people study foreign languages, but less than 10% can speak them fluently. We are starting to build an environment of interactive communication – AI Language Tutor – to speak and make mistakes without fear of judgment.

Our goal is to build a product that will learn together with the user – gather data about them, personalize the approach and motivate to new steps. We do not believe in universal approaches to learning, but we know that algorithms will help the user learn in his own way of learning. And (finally) effectively.

This product still needs to be built. So if building something from scratch is about you, let’s do it together! What should you know about Skelar? This is a venture builder – in other words, a company that builds companies. With us, founders create consumer businesses that become leaders in global markets EdTech, Mental health, Petcare, FashionTech and others.

Skelar people build tech products that win awards from Product Hunt, The Webby Awards and receive thousands of positive reviews on TrustPilot. In total, tech products of our businesses are used by 10+ million people worldwide. All thanks to strong teams, because our specialists are the key value of Skelar.

For professional implementation, we have created an environment with expertise and unlimited opportunities – and we are looking for those who seek challenges. Being in the top five teams today means directly deciding what this business will be like. So we invite you to go on this journey with us.

You will lead the development of our key asset – a mobile application AI tutor. At the 0 to 1 stage, you will personally lay the foundation of the mobile architecture, write the first lines of code MVP and set up release processes. Since the basis of our product is voice communication with AI in real time, your main technical task will be to ensure a seamless, fast and stable user experience.

What you will need to do:

• Development of MVP from scratch: hands-on coding, selection of optimal libraries and building a scalable mobile application architecture;
• Voice & AI integration: implementation of the functionality of recording, processing and playing back audio in real time (interaction with the backend and LLM to ensure minimal response delay);
• UI/UX implementation: close cooperation with designers and Product Manager to create a convenient, intuitive interface and smooth animations;
• Release Management: setting up CI/CD processes, managing releases in App Store and Google Play;
• Leadership: mentoring, conducting code reviews and future hiring of engineers into your team.

What we expect from you (Qualification):

• Experience: 4–5+ years in mobile development (Senior / Tech Lead level);
• Technical expertise: deep knowledge of the main React Native stack and understanding of the mobile application lifecycle;
• Leadership experience: successful experience in managing a team of developers, performing the role of Tech Lead or mentoring;
• Work with audio/network: experience in optimizing application performance, working with complex API integrations;
• Startup mindset: focus on business results; ability to find a compromise between the ideal architecture and the speed of testing hypotheses in the market.

It will be a big plus:

• Experience with speech recognition/synthesis technologies (Speech-to-Text, Text-to-Speech);
• Experience in building applications with a subscription monetization model;
• Previous experience working in early-stage startups or the EdTech niche.

We have built an environment for professional self-realization at Skelar:

• SKELAR Platform . This is the operational core of the venture builder, helping founders to quickly go from zero to one. So business teams focus on the product – and 10+ teams in the Platform close functions Legal, Finance, HR, Admin, Talent Acquisition, Employer Branding, IT and others.

• Networking and knowledge sharing as part of the culture. Among our colleagues are co-founders who have launched more than one business, as well as the strongest specialists in the market. So we have access to the necessary expertise at the touch of a button.

• Exclusive domain education. We have created our own training programs for teammates to choose from – from a 2-month school for junior managers to intensive courses on AI and professional clubs on development, product management, etc.

• Impact on systemic support for Ukraine. We have the charitable foundation Skelar foundation, created by the Skelar people themselves – and thanks to each employee, we implement important social projects. For example, we founded the first in Europe accelerator for veterans and are forming a platform to support veterans at the state level.

• Ecosystem for productive work. For Skelar people, spaces have been created that inspire results – with their own gym, rock climbing wall, Bali green areas and libraries. In spaces where service, security and comfort are synchronized with the pace of team growth, we get a wow experience and work more effectively.

• Care for daily comfort. Breakfasts, lunches, access to sports training in Kyiv or partial compensation for training in Warsaw, medical insurance, paid business trips if the role specifics require such trips, corporate discounts from partners.

We will tell you more at our meeting-get-to-know-each-other.

We invite you to build the next big everything at Skelar together!
