Senior Backend Engineer

## Responsibilities ### Core Responsibilities - Build and Scale AI Agent Infrastructure - Design and implement backend systems that power AI-driven workflows (outreach, qualification, scheduling, follow-ups) - Build orchestration layers for multi-step AI agent execution - Ensure agents can operate reliably, deterministically, and at scale ### Design Core Backend Systems - Architect scalable services for messaging, scheduling, and CRM automation - Build APIs and backend services that support both internal systems and customer-facing products - Define system boundaries, data models, and service interactions ### Integrations with Enterprise Systems - Integrate with CRMs, calendars, marketing tools, and external financial platforms - Build robust, fault-tolerant pipelines for syncing and transforming data across systems - Handle edge cases across fragmented enterprise infrastructure ### Reliability, Performance, and Observability - Ensure system uptime, stability, and fault tolerance in production - Build monitoring, logging, and alerting systems - Identify and eliminate bottlenecks in distributed workflows ### AI System Support (Cross-functional with ML) - Collaborate with ML engineers to productionize LLM workflows and agent logic - Implement guardrails, validation layers, and fallback systems for AI outputs - Support evaluation pipelines for measuring AI performance and reliability ### Product-Focused Engineering - Work directly with founders and product to define features and architecture - Turn ambiguous requirements into clear, scalable technical systems - Ship quickly and iterate based on real customer feedback ## What Success Looks Like - You build systems that allow AI agents to reliably execute complex workflows end-to-end - You reduce manual effort for advisors by automating real operational work - You help turn a fast-moving prototype into a stable, scalable enterprise-grade product - You operate with high ownership and can independently drive large parts of the backend stack This role is ideal for someone who thrives in 0→1 environments, enjoys building systems from scratch, and wants to have outsized impact in a small, high-agency team.
