About the role

You will be a Core Developer in our product team, taking charge of developing and scaling our mobile product. This is a high-impact position where you’ll be involved in the entire product lifecycle: from building core product features and modern UIs to designing a reliable, fast, and efficient infrastructure around it. You’ll work directly day-to-day with the General Manager and have a clear, measurable impact on the product’s unit economics.

Technical stack: AI-driven Engineering, Flutter, Node, TS, React.

We are open to candidates with no prior Flutter experience.

What you need for this position

• You’re an AI-augmented engineer. You actively use tools like Copilot, Cursor, or Claude to speed up your routine, refactor efficiently, and solve problems faster.
• At least 5 years of hands-on experience as a Software Engineer (designing & developing both mobile (primarily) and web applications).
• You communicate openly and feel comfortable in a fast-paced agile team where things can change rapidly.
• You’re a truly product-oriented engineer. You don’t just write code in a vacuum — your technical decisions are always driven by real product and engineering metrics, keeping business goals in mind.
• You can solve product and business problems end-to-end completely solo. You know how to take a high-level problem description and turn it into an efficient, working engineering solution without needing someone to hold your hand.
• Familiarity with Google Cloud Platform, particularly Firebase services including Firestore, Storage, and Performance, as well as experience with Firebase Flutter SDK, Bloc, and Hive storage.
• Hands-on experience building backend (Node.js and Lambda preferred). We value any strong backend background; if you haven’t used our specific stack, we expect you to bridge the gap using AI tools and a high “speed of learning” to ship production-ready code.

What You’ll Be Doing

• Design, build, and maintain mobile app and its infra using Flutter and a Node.js backend. Develop and optimize web-frontend (marketing funnels).
• Leverage AI tools (Cursor, Copilot, etc.) to accelerate development, refactor code, and maintain high code quality.
• Take an active role in product management: monitoring how users interact with your features and identifying areas for improvement. You will analyze user flow through marketing funnels, identifying drop-off points and technical bottlenecks that affect conversion. You won’t just wait for tasks; you’ll proactively suggest tech improvements based on data insights.
• Design and implement A/B tests to validate hypotheses, working closely with the product team to optimize core metrics.
• Build a robust, scalable infrastructure.
• Work directly with the General Manager and marketing team to align engineering efforts with business growth and scalability.

Hiring Process

Stage 1: Interview with HR (1h).

Stage 2: Interview with VP of Engineering.

Stage 3: Technical interview.

Stage 4: Interview with the team.

What we offer for your success

• Very warm and friendly working environment and flexible working schedule.
• 20 days off + paid national holidays, and 12 sick days paid by the company per year.
• Medical insurance, and health protection programs (with COVID-19 and dental coverage).
• Continuous professional development and growth opportunities.
