About the Role

Tesoro AI is recruiting a hands-on Senior Software Engineer to join a U.S. healthcare technology company building AI-enabled applications and operational workflows.

We are looking for an application-oriented engineer who can contribute directly to an existing production codebase, build backend services and integrations, solve complex production problems, and take ownership of software quality after deployment.

Direct experience with Voice AI, healthcare, or Salesforce is valuable, but it is not required. Strong candidates may come from other AI-enabled, real-time, distributed, enterprise, or regulated environments.

What You Will Do
- Build, improve, and maintain production applications, backend services, APIs, and integrations.
- Contribute to AI-enabled functionality used in real operational workflows.
- Improve application performance, reliability, scalability, and response times.
- Investigate and resolve production issues across application, data, integration, and infrastructure boundaries.
- Develop automated tests and strengthen regression prevention,



monitoring, observability, and release verification.
- Identify potential failure modes and implement safeguards, fallbacks, or human-review mechanisms for AI-enabled features.
- Work with product, operations, and technical stakeholders to clarify problems and translate them into practical solutions.
- Contribute to real-time and low-latency workflows, including voice-related applications.
- Own technical work from problem clarification through implementation, deployment, and production validation.
- Use modern AI-assisted development tools responsibly while verifying the quality and reliability of generated code.

What We Are Looking For
- Strong hands-on experience building and maintaining production applications or backend systems.
- Meaningful production experience with Python, including services, APIs, integrations, application logic, debugging, or data-processing workflows.
- Demonstrated
