Job Description

We are looking for a Senior Backend Engineer with strong backend engineering skills and experience with AI engineering . You should be comfortable working across the stack, but your core strength should be building scalable backend systems, APIs, and AI-powered product features. You will own features end-to-end, from architecture and development to deployment, monitoring, and support.

Roles & Responsibilities

  • Design and build backend systems that power real-time, low-latency AI experiences and distributed systems

  • Build AI-powered features and production-grade agentic workflows.

  • Build async and event-driven systems using queues, workers, WebSockets, or streaming

  • Build and evolve conversational AI systems: dialogue management, context handling, intent routing, fallback design

  • Own the infra behind AI features: streaming responses, WebSocket/SSE pipelines, queue-based orchestration

  • Make product-level decisions: you’ll have opinions on what to build, not just how to build it

  • Work on voice-enabled systems (STT/TTS, streaming APIs) as part of end-user experiences

  • Deploy and operate services with a focus on low latency, high availability, and robustness

  • Instrument, monitor, and improve AI systems in production (eval frameworks, latency tracking, cost optimization)

Skills required

  • 3-4 years of software engineering experience

  • Strong proficiency in Node.js, Python, TypeScript, REST APIs, GraphQL, and backend architecture

  • Strong understanding of databases, caching, async processing, and system design

  • Experience integrating LLMs and building Agentic AI powered products

  • Hands-on experience building with LLMs: prompt engineering, function/tool calling, RAG, embeddings, fine-tuning awareness

  • Experience in building AI-driven products, voice and conversational experiences

  • Strong systems design instincts, with a practical mindset for navigating technical tradeoffs

  • Product thinking: you understand why you’re building something, not just the ticket description

  • Comfort with ambiguity: AI product development is fast, iterative, and occasionally chaotic

Strong Signals

  • Built or shipped AI products (voice or text chatbots, copilots, assistants)

  • Experience designing evaluation and feedback loops for AI systems

  • Open-source contributions or strong personal projects

What We Value

  • AI-native engineering mindset with full-stack execution ability

  • Strong ownership and ability to drive projects independently

  • Curiosity for AI and modern engineering practices

  • Clear communication and comfort working in a fast-paced startup environment
