The team values genuine connections and equips marketing, sales, and customer care teams with direct, effective, and personal communication tools. Company Culture Our culture is built on four principles: unwavering passion for what we do, customer-first success, teamwork and collaboration, and an entrepreneurial, results-driven mindset. Key Responsibilities * Design, build, and maintain scalable, high-performance APIs using Python and Django. * Contribute to backend services written in Golang where performance and concurrency are critical. * Define and optimize PostgreSQL schemas, queries, and indexes for efficiency and scalability. * Ensure robust authentication, authorization, and data protection mechanisms. * Manage and optimize AWS environments (EC2, Lambda, RDS, S3, API Gateway, ECS) and CI/CD pipelines (GitHub Actions, AWS CodeBuild, or similar). * Apply infrastructure-as-code practices (Terraform, CloudFormation). AI-Driven Development (Vibe Coding) Work closely with AI coding assistants to generate, refactor, and maintain production-ready code, aiming for at least 75 % of development to be AI-assisted. Focus on architecture, orchestration, and review rather than manual coding. Design effective prompts, validate AI-generated code, and ensure compliance with performance and security standards. Help evolve internal "Vibe Coding" workflows and best practices for human-AI collaboration. Collaboration & Quality Collaborate cross-functionally with frontend developers, designers, and product owners. Write clean, maintainable, and well-tested code aligned with project goals. Required Experience * 3 + years in backend development with production-grade systems. * Strong proficiency in Python and Django, with working knowledge of Golang. * Experience with query optimization and migrations in PostgreSQL. * Solid understanding of AWS cloud services and a serverless mindset (Lambda, Fargate). * Experience with Docker, CI/CD, and infrastructure automation (Terraform, CloudFormation). * Familiarity with testing frameworks (PyTest, unittest). * Strong communication and teamwork in Agile environments. * Experience using AI-assisted development tools such as Cursor, Windsurf, or similar. * Monitoring & logging with Grafana and AWS CloudWatch. * Contributions or side projects showcasing backend, AI, or automation expertise. * Comfortable in a multilingual, English-first, async international team.
