What you will do

• Design, develop, and maintain backend applications and RESTful APIs.
• Develop scalable backend services and fullstack applications using but not limited to PHP full stack.

• Design and manage database schemas, and optimize queries for both Relational and Non-Relational Database Management Systems.
• Create and maintain CI/CD pipelines to ensure reliable and automated deployments.

• Strong SQL skills (MySQL or PostgreSQL), including expert-level schema design, complex query optimization, and indexing strategies.
• Proven experience building resilient enterprise-grade integrations (handling complex OAuth lifecycles and 429 rate-limiting) and leveraging Redis and advanced caching strategies.
• An obsession with code quality, engineering best practices, and maintaining high testing coverage to ensure system reliability, even if strict TDD isn’t your primary approach.
• Deep proficiency with observability tools (such as Datadog or Cloud Logging) and advanced debugging techniques to troubleshoot complex distributed systems.
• Hands-on experience with containerization and local environment automation using Docker, GNU Make, and Bash scripting.
• Proficient in modern, AI-augmented development using tools like Cursor, Claude Code, or Gemini to automate repetitive tasks and optimize the development lifecycle.

Nice to have

• Experience with Google BigQuery for TB-scale processing, including table partitioning, clustering, and slot management.
• Ability to build APM dashboards (Application Performance Monitoring).
• Familiarity with Infrastructure as Code (Terraform) to manage cloud computing resources on GCP or AWS.
• Domain experience in marketing technology, specifically such as mobile event attribution (Adjust) or Google GA4.
