Job summary

Pivotal Health is hiring a back-end leaning Full-Stack Staff Software Engineer to help build new products from the ground up. The role focuses on APIs, backend systems, data flows, and AI-driven product surfaces.

You’ll own product behavior end to end and work across backend and frontend components in a fast-paced, high-ambiguity environment. You’ll collaborate with product, design, operations, and AI/ML partners to turn ideas into shipped experiences.

Qualifications

• Strong backend engineering skills with focus on API design and data modeling.
• Experience building scalable product backends and data-heavy applications.
• Proficiency in Python and modern backend frameworks (e.g., FastAPI).
• Experience with relational databases and data systems (PostgreSQL/SQLAlchemy).
• Familiarity with cloud environments (GCP) and frontend involvement is a plus.

Responsibilities

• Build new product experiences from 0 to 1 across backend services, APIs, integrations, and frontend workflows
• Design and implement backend systems that power product logic, orchestration, data access, and AI-enabled workflows
• Contribute to frontend product development in React-based applications, especially where frontend-backend iteration is tight
• Work closely with product, design, operations, and AI/ML partners to turn ambiguous ideas into shipped product
• Prototype quickly, then harden what works into maintainable product systems
• Build internal and customer-facing workflows that use AI, structured data, and software automation to increase leverage
• Help define product requirements through direct technical judgment, not just implementation after decisions are made
• Improve product quality through instrumentation, testing, thoughtful system design, and strong engineering hygiene
• Use AI actively in your own workflow for coding, debugging, investigation, product exploration, and iteration
• Raise the team's velocity by bringing AI-native working habits, practical engineering judgment, and strong product instincts
