Software Engineer (3+ YOE) at ShortLoop 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: • 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.
