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. You will have significant ownership working across the stack to build and scale the core of our AI agent platform. We are looking for builders with 5+ years of experience, preferably with an early-stage startup background (Pre-seed to Series A).
Kato is building a compliance-first AI servicing platform for the $24B lending market. While others treat regulatory guardrails as an afterthought, we’ve built a regulatory rules system with an AI decision engine on top. Our first product is a Voice AI agent currently handling loan servicing calls for major fintechs like Bilt Rewards and Parafin.
We are backed by Pear VC and angels from Brex, Bridge, and Square. You’ll be our second engineering hire, working directly with our CTO (ex-Google/Brex EM) and CEO (ex-Goldman/Brex).
The Role: As an early hire, you’ll own mission-critical projects across the entire stack. You’ll lead the architecture of our real-time voice processing system, optimize LLM integrations for compliance-aware conversations, and build out our customer-facing dashboards.
Tech Stack:
Backend: Golang, PostgreSQL
Frontend: Next.js, TypeScript, React, Tailwind
Infra: AWS, Terraform, Kubernetes, Docker
AI/ML: LLMs, Speech-to-Text, Text-to-Speech
Requirements:
2-5 years of production software experience.
Strong API design and architectural thinking.
An "owner's mindset"—we are a small, high-intensity team where everyone drives product direction.
Experience with WebRTC, real-time audio, or FinTech is a plus but not required.
Location: San Francisco (4 days/week in-person).

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. We've helped engineerings teams at: Google X, Zillow, and Brex to understand why their builds fail, which tests are flaky, and how to ship code faster without sacrificing reliability. 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.
Unlimited PTO (and we all actually take PTO), competitive salary and equity packages! Please apply here: https://trunk.io/jobs
