- Develop and operate scalable backend services in complex, distributed environments
- Balance hands-on engineering with technical leadership through design reviews, code reviews, and mentoring
- Collaborate closely with engineers, product managers, QA, UX/UI designers, and security experts across the organization
- Identify and implement improvements to reliability, performance, observability, and test coverage
Requirements
- Bachelor’s degree in Computer Science or equivalent practical experience, with 8+ years of software engineering experience
- Strong backend engineering experience with Python, including designing, debugging, and maintaining production-grade services that integrate with SQL/PostgreSQL
- Hands-on frontend development experience with JavaScript, including building user-facing functionality and integrating with REST APIs
- Experience deploying and operating production systems using Linux, Git, Docker, and CI/CD pipelines, preferably in distributed environments
Nice to have
- Experience building AI/ML-powered production features, or working in security, infrastructure-heavy, Big Data, or Spark environments
Personal skills
- Strong analytical thinking and problem-solving skills
- Ability to work independently, take ownership from design to production, and collaborate effectively across teams
Benefits
- Strong community: Work alongside top professionals in a friendly, open-door environment
- Growth focus: Take on large-scale projects with a global impact and expand your expertise
- Tailored learning: Boost your skills with internal events (meetups, conferences, workshops), Udemy access, language courses, and company-paid certifications
- Endless opportunities: Explore diverse domains through internal mobility, finding the best fit to gain hands-on experience with cutting-edge technologies
- Flexibility: Enjoy radical flexibility – work remotely or from an office, your choice
