Principal Full-Stack Engineer

Search Atlas is an AI-native marketing platform that is defining its own category. They are seeking a Principal Full-Stack Engineer to lead cross-product technical initiatives, architect backend foundations, and engage in frontend work when necessary.

Responsibilities:

• Lead backend initiatives that span multiple products, architecting Django REST Framework services, Celery task orchestration, and PostgreSQL data models used company-wide
• Set the technical bar for coding standards, observability, and performance across every team, not just your own
• Step into frontend work when it matters, shipping React and Next.js components with the same rigor you bring to backend systems
• Drive performance across the stack, from API and Celery worker tuning to killing slow renders and bloated bundles
• Standardize observability end to end across Sentry, Datadog, and Grafana, so every service gets the same level of visibility
• Mentor engineers through code review and design sessions, and be the person people go to before a decision gets made, not after

Requirements:

• 8+ years with Python 3 and Django REST Framework, plus hands-on experience with React, Next.js, and TypeScript
• Deep understanding of Django internals, ORM optimization, and REST API design
• Proven experience architecting distributed systems and async processing with Celery
• Strong PostgreSQL expertise: schema design, indexing, query optimization
• Production experience with observability stacks: Sentry, Datadog, Grafana
• Daily fluency with Claude Code, Cursor, or similar agentic development tools
• Comfortable in Git-based workflows, GitLab preferred
• Available during EST or GMT+1 working hours
• Bonus points if you've worked with ClickHouse or Elasticsearch at scale, or have Kubernetes exposure
