Senior AI/ML Engineer
Location: Remote, United States
Department: Product Team
Experience: 4+
Senior AI/ML Engineer
Full-Time Remote • Engineering • AI Products
About the Role
We are building the next generation of AI-powered products — from AI receptionists and call intelligence to medical scribes and workflow automation. As our Senior AI/ML Engineer, you will be the technical backbone of our AI function: defining architecture, evaluating and integrating cutting-edge tools and models, and leading a small team of junior engineers to deliver reliable, scalable AI systems in production.
This is a high-ownership role for someone who thrives at the intersection of research and real-world product engineering.
What You'll Do
Technical Leadership
Evaluate and select AI/ML tools, frameworks, models, and infrastructure best suited for products like AI receptionists, call intelligence, and AI scribes
Design end-to-end AI system architectures covering speech, LLMs, RAG pipelines, real-time inference, and data workflows
Define engineering standards, best practices, and code review processes for the AI team
Make key build-vs-buy decisions and vendor evaluations for AI services and APIs
Product Delivery
Own the AI layer of our core products — from prototyping and experimentation to production deployment
Stabilise and improve existing AI features: reduce latency, increase accuracy, and improve robustness
Collaborate with product managers and founders to translate business requirements into AI system design
Set up monitoring, alerting, and evaluation pipelines to track model and system performance in production
Team Management
Lead and mentor a team of 2–3 junior AI/ML engineers through code reviews, pair programming, and technical guidance
Break down complex AI problems into well-scoped tasks and delegate effectively
Create a culture of experimentation, rigour, and continuous learning within the team
Research & Innovation
Stay current with the latest developments in LLMs, speech AI, and agentic systems
Identify opportunities to leverage new models or techniques to improve product capabilities
Run structured experiments and present findings to inform product and engineering decisions
What We're Looking For
Required
4+ years of experience in AI/ML engineering, with at least 2 years in production environments
Hands-on experience building systems using LLMs (OpenAI, Anthropic, Gemini, or open-source models)
Strong proficiency in Python and ML frameworks (PyTorch, Hugging Face, LangChain/LlamaIndex, etc.)
Experience with speech and audio AI: ASR (e.g. Whisper, Deepgram), TTS, or orchestration platforms (Vapi, Livekit, Retell)
Solid understanding of RAG architectures, vector databases (Pinecone, Weaviate, pgvector), and prompt engineering
Experience deploying and scaling AI systems on cloud infrastructure (AWS, GCP, or Azure)
Track record of leading technical initiatives and mentoring junior engineers
Strong communication skills — able to articulate technical trade-offs to non-technical stakeholders
Nice to Have
Experience with real-time AI systems (low-latency speech, streaming inference)
Familiarity with healthcare or medical documentation workflows (for AI scribe use cases)
Experience with telephony or VoIP platforms (Twilio, Vonage, Plivo)
Knowledge of multi-agent frameworks and agentic AI workflows
Prior experience at a startup or in a 0-to-1 product environment
