Clario is a consumer cybersecurity company founded in 2019 with its engineering base in Kyiv. Its app combines antivirus, virtual private network and privacy tools with human support. The product is used by consumers worldwide.

We are Clario, a consumer-focused company on a mission to make digital life easy. We’re here to create smart yet simple apps with a human touch, empowering better productivity, security, and lifestyles. With mature products used by millions worldwide and years of in-house product development, we're waiting to unleash your hidden talents and make you sparkle. Join us and let’s go together!

About the role

You will be a Core Developer in one of the product teams, taking charge of developing and scaling our mobile product and its ecosystem. 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, TS, Firebase, Node.

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.

We are not just a company, we are Clario! We put the customer at the heart of all that we do, we achieve our best together, take responsibility, and challenge our limits to create a difference!

To apply for this position, please send your CV (in English only) with a detailed description of your career, experience, skills, and projects. We guarantee the privacy of any information received.
