Our Mission

Frontera exists to close the care gap: every child, no matter where they live, should be able to access effective behavioral healthcare.

The Role

We are looking for a highly skilled and versatile Senior Machine Learning Engineer to join our team and play a key role in architecting, developing, and scaling our AI and ML capabilities. You will lead the development of core systems, including our chatbot and other ML-powered products, while collaborating closely with clinicians, product managers, and engineers to solve complex real-world problems in pediatric behavioral healthcare.

Responsibilities

  • Lead the design, development, and deployment of ML/AI-powered systems, including chatbots, workflows, and backend infrastructure.
  • Collaborate with ML researchers, product managers, and subject matter experts to translate prototypes into production-ready solutions.
  • Build, maintain, and optimize scalable data pipelines, model training frameworks, and workflow orchestration systems (e.g., Temporal, Airflow, Vellum).
  • Contribute to API/schema design, backend development (Python/Django), and web programming as needed.
  • Troubleshoot and resolve complex technical problems across distributed systems and ML pipelines.
  • Mentor junior engineers and help define best practices for engineering and ML operations within the team.
  • Adapt to evolving project requirements in a fast-paced, early-stage startup environment.

Qualifications

  • 8+ years of experience in software engineering, with strong backend and web development experience.
  • Proven expertise in Python, web frameworks (e.g., Django), GraphQL, workflow orchestration tools (e.g., Temporal, Airflow), and API/schema design.
  • Hands-on experience with ML pipelines, model training frameworks, and cloud infrastructure.
  • Experience working cross-functionally with product, engineering, and domain experts.
  • Strong debugging skills and ability to tackle hard technical problems.
  • Early-stage startup experience preferred, with flexibility, scrappiness, and willingness to pivot.
  • Excellent communication, mentoring, and collaboration skills.
  • Experience with LLMs, RAG frameworks, chatbots, or generative AI is a plus.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
