As a Client Operations Engineer (Growth Expert) at GrowthX, your responsibilities include designing and building custom solutions ranging from AI-powered workflows to full-stack applications that leverage technical SEO, marketing expertise, and technical skills. You will occasionally interface directly with clients and work closely with internal teams to translate client requirements into technical solutions that drive measurable growth. Your work spans the entire development lifecycle from conceptualization and architecture to implementation, testing, and deployment. You will also contribute to internal projects by developing tools for the marketing team and creating micro-applications on top of the AI stack, bridging marketing and engineering in both external client projects and internal innovation. Day-to-day tasks vary and may include updating websites and micro-apps, developing client-specific applications over several months, configuring large language models (LLMs) to power new AI workflows, and building internal tools to streamline operations. You are expected to work in a fully remote environment with flexible scheduling that requires at least 4 hours of overlap with US Pacific Time for synchronous collaboration.

As a Senior Software Engineer (AI Voice Agents) at Heidi, you will work closely with the Engineering Manager and Product Lead to build end-to-end AI features including architecting and shipping fullstack solutions that leverage voice AI and large language models (LLMs) to automate clinical workflows. You will operationalize voice AI by implementing and fine-tuning audio processing pipelines to ensure that Automatic Speech Recognition (ASR) and LLM agents perform accurately in diverse, real-world medical environments. You will translate complex clinical feedback into technical solutions by rapidly prototyping and deploying improvements to model behavior, prompting strategies, and audio handling. Optimizing fullstack performance for real-time audio streaming and token generation to minimize latency for clinicians is a key responsibility. Additionally, you will act as a technical liaison for enterprise customers to bridge the gap between their complex infrastructure needs and the core platform, delivering seamless and scalable integrations within large healthcare environments. You will also partner with implementation and clinical teams to shorten feedback loops by shipping critical integrations and feature requests from concept to production swiftly.
