Software Engineer (Senior)

ShortLoop builds high-reliability AI phone agents that autonomously manage conversations for automotive dealerships. These agents book service appointments, qualify leads, and integrate deeply into dealership workflows - requiring tight SLAs, fault-tolerant systems, and fast, context-aware reasoning. As a software engineer on the team, you will design, scale, and evolve the infrastructure that powers these real-time Agentic AI systems. ## **What you’ll be doing** This role is highly cross-functional and involves substantial ownership of system behavior, architecture, and execution. * Leading design and implementation of real-time communication and conversation systems. * Scaling the infrastructure for our Agentic AI pipelines (LLMs, tools, decision loops). * Owning major backend components - from API surfaces to integration layers to data persistence. * Architecting cloud-native systems with a focus on resilience, latency, and cost efficiency. * Shaping engineering practices, performance monitoring, testing strategy, and deployment processes. * Collaborating directly with the founding team to align architecture with product roadmap. * Supporting integrations with dealership management software and task automation workflows. ## **About you** * 3 - 5 years in a full-time engineering role building production systems. * Strong experience architecting scalable, secure, and observable cloud applications. * Ability to independently scope, design, and execute complex system components. * Experience with data infrastructure, event-driven architectures, or distributed systems. * Comfortable working in a fast-moving early-stage environment with high autonomy. * You take initiative - if something is broken, ambiguous, or inefficient, you drive the fix. ## **Nice to have** * Experience building from 0 → 1 or working in early-stage teams. * Familiarity with LLM-based reasoning systems, speech pipelines, or real-time telephony (SIP, WebRTC). * Performance tuning experience - query optimization, caching strategies, concurrent systems. * Experience designing internal tools or workflow automation at scale. ## **Our tech stack** Azure, AWS, Python, Node.js, React, MongoDB, ClickHouse.
