Our tech stack includes Node.js, JavaScript, TypeScript, React, MongoDB, Redis, and a few other technologies. If you are an experienced backend engineer who enjoys owning features end-to-end, solving complex problems, and delivering high-quality software in fast iterations, this role will be a strong fit.

Hands-on experience building, deploying, and operating production systems
Familiarity with modern JavaScript frameworks (React, Angular, or Vue)
Experience with cloud platforms (AWS preferred; Azure or GCP also acceptable)
Strong understanding of software design principles and best practices
Strong ownership mindset – you take end-to-end responsibility and consistently deliver reliable, well-thought-through solutions
Product-oriented thinking – you build with long-term maintainability, scalability, and user impact in mind
Continuous learning mindset and willingness to grow together with the team – actively developing your skills while contributing to the team’s collective knowledge
Proactive and collaborative approach to problem-solving – you identify challenges early, communicate clearly, and work effectively with others to find solutions
Commitment to quality, efficiency, and continuous improvement
