About Our Client Workana 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).
