○ Gain experience with containerization technologies (e.g., Docker) and contribute to CI/CD pipelines.
● Database Management:
○ Develop and contribute to the optimization of SQL (e.g., PostgreSQL, MySQL) and NoSQL database solutions.
○ Ensure data integrity and contribute to performance improvements in database operations.
● AI Tool Integration & Innovation:
○ Actively utilize and explore AI developer tools (e.g., Cursor, Claude Code, Gemini) to streamline coding, debugging, and learning processes.
○ Contribute to best practices for leveraging AI tools within the engineering team.
● Code Quality and Collaboration:
○ Uphold high standards of code quality through diligent development, participation in code reviews, and writing unit/integration tests.
○ Support junior team members and actively participate in a culture of continuous learning and knowledge sharing.
● Project Contribution:
○ Contribute significantly to development projects, taking ownership of features and tasks.
○ Collaborate with product managers and designers to understand requirements and translate them into technical solutions.
What we’re looking for:
● Education: Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
● Experience:
○ 2-4 years of proven experience in a software engineering role.
○ Solid experience in full-stack development, with demonstrable skills in JavaScript, TypeScript, Node.js (for backend), and React (for frontend). A stronger inclination and experience towards backend development is preferred.
○ Proficiency in building and consuming RESTful APIs; familiarity with GraphQL is a plus.
○ Experience with relational databases (e.g., MySQL, PostgreSQL) and/or NoSQL databases.
○ Hands-on experience with cloud services (AWS or Google Cloud Platform), including deploying and maintaining applications.
○ Familiarity with version control systems (e.g., Git).
○ Experience with frontend state management libraries (e.g., Zustand, Redux) is a plus.
● AI Tool Proficiency:
○ A keen interest in and demonstrable experience or strong willingness to learn and leverage AI developer tools (e.g., Cursor, Claude Code, Gemini, GitHub Copilot) to improve development workflows and code quality.
● Skills & Attributes:
○ Good analytical and problem-solving skills with the ability to develop, optimize, and troubleshoot applications.
○ Strong communication skills and ability to collaborate effectively within a team environment.
○ A proactive attitude, eager to learn new technologies and take on challenges.
● Passion: Individuals who are passionate about technology, the virtual world, and have a genuine interest in working for a high-growth company in an exciting industry.
● Industry: Previous experience in marketing technology products, a startup, or a SaaS company would be a benefit.
