Careforce AI (aka Helpcare) | Senior Fullstack Engineer | REMOTE (US) Location: Remote (US) Remote: Yes (US Only) Willing to relocate: No Technologies: Python, FastAPI, React, Supabase, GCP, LLMs Résumé/CV: https://bookface.ycombinator.com/company/30124/jobs/78672 Email: Apply via link above

Description: Careforce AI is building autonomous AI agents that eliminate the manual administrative burden in healthcare (fax machines, scheduling, calling). We find, call, and schedule patients, breaking interoperability barriers that have plagued the industry for 40 years. We are a well-funded, YC-backed company with massive customer demand.

We are looking for a Senior Fullstack Engineer to be a foundational member of our small, ambitious team.

Decise | Principal Engineer & Technical Strategist | Remote (US) | Fully Remote | Contract (1099)

Decise is a hands-on advisory and delivery firm that helps organizations unlock the full value of their technology and improve business profitability.

We work directly with executives to define what should be built, then we build it. Our work spans software engineering, data platforms, analytics, and customer-facing digital products. We often operate as fractional CIOs and CTOs, guiding both the strategic direction and the technical execution of our clients’ technology initiatives.

Our clients rely on us to turn complex business problems into working systems — not slide decks.

We are intentionally small and senior. Everyone on the team is a builder who can operate independently, solve complex problems, and deliver finished systems that people actually use.

White-glove service. Blue-collar grit.

We’re looking for a principal-level technologist who can move between engineering, architecture, and client strategy. Most of your time will be spent building systems and writing production code. The rest will involve working directly with executives to shape technical direction and ensure the work creates real business value.

Typical technologies we work with include React, Angular, Next.js, Node.js, Go, Snowflake, SQL, dbt, Domo, Streamlit, AWS, Vercel, and modern AI-assisted engineering tools. The exact stack varies by client; the ability to learn quickly and move confidently across technologies matters more than any specific tool.

Strong candidates typically have 10–15 years of experience building production systems and are comfortable operating both as hands-on engineers and as technical advisors to executives.

This is a long-term, full-time independent contractor engagement (1099). Everyone at Decise — including the founders — operates in this structure. Compensation is designed to be competitive with senior engineering roles at leading technology companies.

The fastest way to stand out is to show us something you’ve built: a production system, GitHub repository, application, or data platform you designed.

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. At Trunk, our mission is to help teams create high-quality software quickly. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!

Our products:

  * Merge Queue: Ensure your PRs keep the builds you care about green at any scale.

  *Flaky Tests: Detect and eliminate Flaky Tests.
