Intermediate - Senior Software Developer FTAI

Aspire Software is looking for an Intermediate - Senior Software Developer 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 are hiring a Senior Full-Stack Engineer to build and ship customer-facing features across the product, from UI to backend services and AI workflows. This role matters right now because our customers depend on fast, reliable call handling and we are expanding what the AI receptionist can do end-to-end. You will own key product areas and help make design and product decisions, not just execute tickets.

Key Responsibilities

• Build full-stack features in our core app, from React/TypeScript UI to Node/TypeScript APIs
• Design and ship AI-assisted workflows (LLM prompts, tool calling, retrieval, evaluation, monitoring) that improve call outcomes
• Own product surfaces that impact conversion, job booking, and customer experience, including onboarding and call summaries
• Make pragmatic UX and product decisions, turning rough problems into clear specs and shippable iterations
• Improve reliability and performance across services (latency, error rates, scalability) for 24/7 usage
• Collaborate with customer success and ops to turn real contractor feedback into product changes weekly
• Set engineering standards for AI development (testing, evals, guardrails, data quality) and raise team velocity
• Contribute to architecture decisions across telephony, data, and AI systems (Twilio, queues, Postgres, observability)

• 4+ years of full-stack experience shipping production web apps in a high-ownership environment; 3+ years building with TypeScript across frontend and backend
• Experience integrating and operating LLM features in production (OpenAI style APIs, prompt/tool design, evals, monitoring)
• Strong product instincts: comfortable choosing tradeoffs in UX, scope, and sequencing with limited direction
• Ability to design clean data models and APIs (Postgres, REST, event-driven patterns)
• Experience building reliable systems with observability (metrics, logs, tracing) and on-call readiness
• Comfortable moving fast: able to ship, measure, and iterate weekly with real customer usage
• Experience with using AI development tools such as Claude Code or others
• Strong written communication: can write clear PRDs, RFCs, and decision notes

Nice To Have:

• Experience with AWS or similar cloud infrastructure
• Experience with telephony, call routing, or Twilio
• Experience with design tools and lightweight product design workflows
• French language skills
