Job Description
About the role We're building a vertical AI Sales OS platform that automates and improves the sales process end-to-end. The goal is simple: human-level sales capability at machine speed, with tight integrations into real workflows (telephony, WhatsApp/CRM handoffs, scheduling, reporting). As a Founding Backend Engineer, you'll own core systems that power real-time voice/chat interactions, campaign execution, data pipelines, and customer-facing reliability. This is a high-ownership role with meaningful ESOP upside. What you'll do
- Build and ship backend services in Python for core product workflows (campaigns, lead orchestration, reporting, integrations).
- Design and maintain scalable REST APIs and internal services.
- Work on real-time systems: event-driven pipelines, queues, streaming workflows, and low-latency services.
- Implement caching and performance optimizations (Redis or equivalent), rate limiting, retries, idempotency, and observability.
- Integrate with external APIs (telephony, STT/TTS providers, LLM endpoints, WhatsApp, CRMs).
- Own reliability: monitoring, incident response, deployment hygiene, and cost-performance tuning.
- Collaborate closely with the founder on architecture, product decisions, and roadmap priorities. What we're looking for (must-have)
- Strong Python backend engineering experience.
- Solid understanding of REST APIs, authentication, and API design best practices.
- Experience building systems with real-time constraints (webhooks, queues, event processing, background workers).
- Practical knowledge of caching concepts (Redis/memcache), database fundamentals, and performance debugging.
- Basic understanding of AI/ML concepts and how to integrate model/API outputs into production systems (LLMs, STT/TTS, embeddings, evaluation basics).
- Comfortable working in ambiguity and taking end-to-end ownership. Good to have
- DevOps skills: Docker, CI/CD, Kubernetes, cloud (GCP/AWS), infra monitoring.
- Experience with distributed systems, message brokers (Kafka/RabbitMQ/SQS), or workflow engines.
- Prior work on voice/telephony systems, WebRTC, or streaming audio pipelines.
- Experience building B2B SaaS (billing, RBAC, audit logs, multi-tenant systems). Why join
- High ownership: you'll build the core backend foundation, not just tickets.
- Real-world impact: your work directly improves customer revenue outcomes.
- Salary + ESOPs in a fast-moving, early-stage startup with strong growth ambition. Location
- In Office position in Gurgaon
