Sonatafy Technology, headquartered in Scottsdale, Arizona, is an award-winning nearshore software development company with a strong reputation. They have a dedicated in-house team of engineers, offering end-to-end software solutions and supporting client development staff augmentation.

About The Role

We are looking for a Senior Software Engineer who is as passionate about building with AI as they are about building AI products. This isn't a research role; it's a builder role. You will be responsible for the end-to-end journey of our most critical products: from the initial spark of an idea (0→1) to scaling and optimizing it into a powerful, reliable growth lever (1→N).

Responsibilities

• 0 to 1 Prototyping to 10+ Clients & Product Creation: Rapidly translate ambiguous ideas into working prototypes and proofs-of-concept using our AI-first toolchain (e.g., Replit, v0, Lovable). Validate feasibility and user value with speed and precision.
• 10 to 100+ Clients Scaling & Growth Engineering: Take successful prototypes and lead the charge in building them into scalable, monitored, and efficient production systems. Identify and implement growth levers within the product using AI.
• AI-Native System Design: Architect and implement robust, cost-effective, and observable systems that deeply integrate LLMs (OpenAI, Anthropic, etc.) and AI services. Your designs will prioritize safety, reliability, and performance in a healthcare context.
• Developer Acceleration: Build the abstractions, internal tools, and APIs that empower every engineer on the team to leverage AI capabilities confidently and responsibly. You don't just build features; you build force multipliers

Requirements

• Proven track record of shipping 0-to-1 products and scaling them to 500k+ of users.
• 5+ years of experience as a full-stack, shipping production software at scale.
• Deep, hands-on fluency with the modern AI dev stack. Proficient with Cursor, leverage Replit/v0 for ideas, and use AI agents (OpenCode, Aider, Void) as core parts of your daily workflow. This is non-negotiable.
• Significant experience integrating, debugging, and monitoring LLMs and other AI services in real-world applications. You understand prompt engineering, cost management, latency, and evaluation frameworks.
• Proficiency in designing distributed systems, APIs (REST, GraphQL), and databases (PostgreSQL). You write clean, tested TypeScript.
• Obsess over user value, metrics, and growth loops. You think in terms of levers and outcomes, not just tasks.
• Experience building evaluation frameworks for AI features (e.g., using Langfuse, Helicone, Lunary).
• Nice to Have:
• Deep knowledge of RAG, vector databases, and intent classification patterns, search optimization, and building intelligent recommendation systems.
• Expertise in Infrastructure-as-Code (Pulumi, Terraform) and containerization (Docker).
• Background in healthcare, HIPAA, or other regulated environments (fintech, etc.).
• You’ve contributed to open-source projects or have a strong presence in the AI dev community. Experience with observability and monitoring systems (Datadog, Grafana, Sentry, Cloudwatch, etc.).
• Experience with containers and orchestrators like Docker or Kubernetes.
