We’re looking for a founding engineer to help build our Parva product. Parva is a mental healthcare company and provides patients with continuous cognitive care in between clinician visits. This person will build and own full-stack features across our patient and clinician products, working directly with the founder.

The ideal candidate is based in New York City or the surrounding area and is comfortable working independently across the full stack, from database design to frontend. Prior healthcare or mental health experience is not required.

Responsibilities

  • Build and ship full-stack features across our patient-facing and clinician-facing web products.
  • Own features end to end, from database and API design through frontend and deployment.
  • Build AI-powered features, including LLM integrations and agent-style systems.
  • Design and maintain the data layer: schemas, migrations, and pipelines.
  • Collaborate directly with the founder to execute the product vision.
  • Fix bugs quickly and keep the product reliable and secure.
  • Help set engineering standards for architecture, testing, and code quality.

Qualifications

  • Based in New York City or able to work in-person in NYC.
  • Strong full-stack engineering skills, with shipped products or projects you can show.
  • Comfortable working without detailed specs and making decisions with incomplete information.
  • Proficiency with Python, TypeScript, React/Next.js, and Postgres.
  • Experience building with LLM APIs.
  • Ability to work independently, manage deadlines, and ship quickly.
  • Comfortable taking feedback and iterating on the same feature.
  • No prior healthcare or mental healthcare experience required.

Nice to Have

  • Experience as an early or founding engineer at a venture-backed startup.
  • Experience with health data, provider datasets, or other regulated/sensitive data environments.
  • Experience with data pipelines, behavioral or time-series data, or applied ML.

Submission Details

  • Full-time, founding engineer role with meaningful equity.
  • New York-based preferred.
