Applied AI Engineer

Role Overview

You'll be one of the first dedicated AI engineers focused on agentic systems at Ascertain. Your near-term mandate is concrete: build voice agents that call payers on our behalf to check the status of prior authorization submissions, follow up on outstanding requests, and capture structured outcomes back into our systems.

What You Will Do

Design, build, and ship voice agents that conduct outbound calls to payers - handling IVR navigation, hold queues, multi-turn dialogue with human reps, and structured data capture. Integrate telephony, speech-to-text, text-to-speech, and LLM components into reliable end-to-end pipelines, and own them in production.

Why It Might Be a Fit

We're looking for an AI engineering generalist who's excited to start with voice and build outward from there. You'll have a hand in shaping how Ascertain builds, evaluates, and operates agents of all kinds—voice, chat, document understanding, internal tooling, and beyond.

Requirements

• 4+ years of professional software engineering experience owning production systems end-to-end—from design through deployment, monitoring, and iteration.
• 2+ years of professional Python experience building APIs, services, or data workflows.
• Hands-on experience developing or deploying LLM-based applications or RAG systems in a real production setting (not just prototypes).
• Comfort operating with ambiguity and shipping the first version of something that doesn't exist yet.

Benefits

• Meaningful work: Your work will directly impact healthcare organizations by reducing administrative burden and improving how care teams operate day to day.
• Ownership and growth: You’ll join Ascertain at an early stage, with meaningful equity and the opportunity to shape our product, technical direction, and how this function evolves over time.
• Competitive compensation: We offer a competitive salary, meaningful equity, comprehensive health benefits, and other standard benefits appropriate for a growing company.
• Flexible work model: This role is remote-friendly. For NYC-based team members, we support a hybrid model with regular in-office collaboration.
• Collaborative team: You’ll work alongside a thoughtful, mission-driven team with backgrounds spanning healthcare operations, product, and engineering.
