Senior Software Engineer (Full Stack)

About the role

Senior Software Engineer (Full Stack)

Location: New York City | In-office

THE MISSION

“Leading healthcare into the agentic era.”

Every day, patients call their clinic to schedule an appointment, ask a question, or request a prescription refill. Behind each conversation is a busy healthcare team coordinating people, information, and systems.

Taxo builds Voice AI agents that take on this administrative work. Our agents connect with EHR and practice management systems to help teams handle patient intake, complex scheduling, and refill requests, with reliable workflows and clear handoffs to people.

THE OPPORTUNITY: BUILD THE PRODUCT END TO END

As our Senior Software Engineer (Full Stack), you’ll build the application layer around Taxo’s AI agents. You’ll work across interfaces, application services, and product data, turning complex healthcare workflows into software that people can use every day. You’ll independently own features from discovery and technical design through implementation, launch, and production operation, building on shared healthcare services and connectors owned by the platform and Healthcare Intelligence teams.

WHAT YOU’LL DO

- Ship End to End: Independently design, build, and ship end-to-end features for healthcare teams, from clear interfaces to the services and data models behind them.

- Connect the Workflow: Develop application APIs and product workflows that use shared healthcare services and connectors to support scheduling, intake, and other operational workflows.

- Practice Product Engineering: Turn product requirements and customer feedback into practical technical designs and shipped software.

- Build for Reliability: Improve performance, reliability, and observability across the application and its external dependencies. Build secure sensitive-data handling, access controls, and auditability into the product.

- Set the Standard: Write tests, strengthen CI/CD, and make releases easier to validate and operate.

- Shape the Architecture: Collaborate with voice AI engineers and product colleagues, review code, and help the team make sound architectural decisions.

THE STACK

We move fast with a modern toolkit:

- Frontend: React, Next.js

- Backend: Node.js (TypeScript)

- Data & Infrastructure: PostgreSQL, AWS

- Intelligence: LLMs and Voice AI integration

WHO YOU ARE

- The Builder: A track record of independently owning production web applications across frontend and backend systems, from technical design through launch and ongoing operation.

- The Full Stack Engineer: Strong TypeScript and JavaScript skills, with hands-on experience in React or Next.js and Node.js.

- The Systems Thinker: Practical knowledge of relational databases, API design, authentication, authorization, and external integrations, with experience handling sensitive data securely and building auditable systems.
