Senior Full-Stack Developer (Node, AWS, LLM) PorT GF

Aspire Software is looking for a Senior Full-Stack Developer (Node, AWS, LLM) to join our team in Lebanon.

Here is a little window into our company :  Aspire Software operates and manages wholly owned software companies, providing mission-critical solutions across multiple verticals. By implementing industry best practices, Aspire delivers a time sensitive integration process, and the operation of a decentralized model has allowed it to become a hub for creating rapid growth by reinvesting in its portfolio.

About the Role

We’re seeking a Senior Full-Stack Developer who loves building production systems end-to-end. You’ll lead the engineering work to launch Sadie in a new vertical, owning critical services across voice, LLM orchestration (prompts / agents / RAG), and partner integrations. This is a hands-on role : designing architecture, writing high-quality code, instrumenting reliability and cost, and working closely with product and partnerships to ship real outcomes.

Key Responsibilities :

• Own services end-to-end for a new Sadie vertical : design, implement, test, deploy, and operate
• Build cloud services on AWS with serverless and containerized components (e.g., AWS Lambda, Docker, Fargate / ECS / EKS) for scalability and resilience
• Optimize performance & reliability for high-concurrency voice interactions (latency budgets, error budgets, observability)
• Measure what matters : set up metrics for containment / conversion, latency (p95), and cost per successful task
• Raise the bar : code reviews, design docs, mentoring, and contribution to on-call with clear SLOs
• Champion best practices in technical product development, scalability, and system design
