Backend Engineer

About Us :

We’re building a conversational voice assistant. Join early to shape core services, data models, and our AI / LLM platform.

The road ahead : We’re scaling to thousands of concurrent calls, maturing an AWS-native platform (secure, observable, cost-aware). You’ll help evolve our LLM / RAG stack, deploy reliable pipelines, and set engineering standards.

What You’ll Do

• Design and own Python / FastAPI microservices (async I / O, WebSockets) for real-time voice / data workflows.
• Model and operate MongoDB / Atlas : schema design, indexing, aggregation pipelines, query tuning, TTL / archival, change streams.
• Integrate third-party APIs / services (auth, webhooks, retries, idem potency, observability) and productionize them.
• Contribute to LLM features : tool / function calling, structured outputs (Pydantic / JSON Schema), RAG, evaluations, safety / guardrails.
• Create and maintain deployment pipelines; add metrics, logs, and traces; drive incident response and postmortems.
• Collaborate with frontend / AI / QA; write docs / run-books; communicate clearly and work as a supportive team member.
