About Us :

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

The road ahead : Were scaling to thousands of concurrent calls, maturing an AWS-native
platform (secure, observable, cost-aware). Youll help evolve our LLM/RAG stack, deploy

reliable pipelines, and set engineering standards.

What Youll 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, idempotency, 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/runbooks; communicate clearly and work as
a supportive team member.

Must-Haves

- 5+ years backend experience with Python (strong) and FastAPI (or similar async frameworks).

- MongoDB proficiency : schema design, indexes, aggregation, profiling, performance tuning; operational know-how on Atlas.

- CI/CD (GitHub Actions/GitLab CI or similar) and Docker.

- Strong debugging across distributed systems; excellent communication and teamwork.

- Proven third-party integration experience (auth, rate limits, pagination, webhooks).

- LLM / AI Experience (Preferred/Plus)

- Server-side integration with providers (e.g., OpenAI/Azure OpenAI/Bedrock) and streaming responses.

- RAG pipelines (chunking, embeddings, vector stores), prompt versioning, structured outputs.

- Evaluation & safety basics (offline eval sets, regression tests, guardrails/PHI redaction, latency & cost tracking).

Nice-to-Haves :

- Node.js/TypeScript for tools/edge services.

- PostgreSQL/Redis; event/messaging (Kafka/Kinesis/RabbitMQ).

- Real-time comms (SIP/WebRTC), audio streaming, STT/TTS.

- Security/compliance awareness (SOC 2, HIPAA), secrets management.

- Hands-on AWS : IAM & VPC basics, S3, SQS/SNS, API Gateway/ALB, CloudWatch; deploy via ECR + ECS/EKS or Lambda.
