Backend Engineer

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.

• 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.

• 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.

• 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).

• 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.
