Senior Fullstack Engineer (Java/kotlin + React)


At Parser, we're searching for full stack enthusiasts who are highly motivated, collaborative, and excited to be part of our Fintech Engineering team.



Key Responsibilities


As a Full Stack Engineer, you'll work on impactful projects using cutting-edge technologies. Collaborating with talented engineers across frontend, backend, and infrastructure, you'll design and build solutions critical to Parser's mission.

You will:


  • Write high-quality, maintainable, and testable code in Java, Kotlin, TypeScript, Python, or other modern stacks.
  • Build across the full stack — frontend web applications, backend services, APIs, and data flows.
  • Work in a cross-functional Agile team, participating in all development phases from planning to production.
  • Provide technical mentorship, conduct code reviews, and engage in architectural discussions.
  • Continuously improve systems for scalability, performance, and resilience.
  • Collaborate with stakeholders to shape product direction and make architecture decisions.




Required Tech Stack & Skills


We value curiosity, creativity, and a passion for building great products. While we don't believe in rigid checklists, experience or interest in the following areas is a plus:


  • Strong programming skills in modern languages (Java, Kotlin, Python, JavaScript, etc.)
  • Experience with frontend frameworks like React, Vue, or Angular
  • Understanding of backend technologies and RESTful APIs
  • Knowledge of cloud platforms such as AWS, GCP, or Azure
  • Familiarity with SQL and NoSQL databases
  • Solid understanding of computer science fundamentals (data structures, algorithms, system design)
  • Passion for clean, maintainable code and modern practices (CI/CD, TDD, DevOps)
  • Strong communication and collaboration skills
  • A drive to learn and improve — both yourself and the systems you build




As a Team, We love to:


  • Build reliable, scalable systems that empower millions of travellers
  • Keep our codebase clean and architecture elegant
  • Learn from each other, share knowledge, and grow together
  • Celebrate wins, reflect on misses, and always aim higher
  • Use our travel perks to explore the world




Some of the benefits you’ll enjoy working with us:


  • A highly competitive compensation package.
  • Medical insurance.
  • The chance to join an organization with triple-digit growth that is changing the paradigm on how software products are built.
  • The opportunity to form part of an amazing, multicultural community of tech experts.
