About Our Client Workana has is looking for a Senior Full-Stack AI Engineer for an AI-native consulting and implementation partner. They help mid-market and enterprise clients modernize critical workflows using Gen-AI, automation, and cloud platforms. They operate with small, senior teams and ship production-ready systems fast, typically live in 8–12 weeks, secure and auditable.

The Role We are looking for a someone who can own delivery, not just execute tickets. This role is for you if you: • Can take ambiguous requirements and turn them into working systems • Are comfortable being the most senior engineer on a stream • Move fast without sacrificing production quality • Have shipped real AI features, not demos

You’ll work closely with a strategist and other senior engineers to design, build, and harden AI-enabled products for real clients. This is hands-on delivery work. No ivory-tower architecture. No babysitting juniors. You build, decide, and ship.

What You’ll Do • Own end-to-end delivery: Design and build full-stack features from UI to backend to deployment. • Ship real AI systems: Implement RAG, tool-calling, agent workflows, structured prompting, evals, and guardrails. • Move fast, responsibly: Prototype quickly, then harden for security, reliability, and cost control. • Use AI as a force multiplier: Work fluently with tools like Cursor, Claude Code, Windsurf, or Copilot to accelerate delivery while maintaining code quality. • Make technical calls: Choose patterns, trade-offs, and scope boundaries without waiting for permission. • Collaborate tightly: Work directly with strategists, clients, and other senior engineers to unblock progress. • Light DevOps ownership: Configure environments, CI/CD, secrets, and deployments (with support when complexity grows).
