What You’ll Do

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

• Architect and implement agentic AI flows: tool calling, multi-step reasoning, orchestration, memory, and planning

• 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)

What We’re Looking For

Must Have:

• 1- 4 years of backend and AI engineering experience. 

• Strong proficiency in Python

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

• Experience with agentic AI patterns: multi-agent orchestration, ReAct loops, planner-executor architectures, or similar

• Strong fundamentals in real-time systems

• Keen interest in building AI-driven products, particularly 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

• Contributed to or built open source developer tools, SDKs, or internal platforms

Bonus

• Experience with voice AI / speech-to-text / text-to-speech pipelines

• Background in distributed systems, message queues (Kafka, RabbitMQ, Redis Streams)

• Exposure to on-device or edge AI inference

• Open-source contributions in the AI/ML space
   

Tech You’ll Likely Touch

LLMs (OpenAI, Anthropic, open-source models), Python/Node.js, Redis, PostgreSQL, WebSockets / SSE, Docker, Kubernetes, vector databases, CI/CD pipelines, observability tools.

What We Value

• Ownership — you see a problem, you fix it. You don’t wait for a spec.

• Speed with taste — ship fast, but ship something you’d want to use yourself.

• Clear thinking — you can explain a complex system in simple terms.

• Curiosity — the AI landscape moves weekly. You keep up because you want to, not because you have to.
