Job description

Senior Backend Engineer (GenAI / LLM Workflows)
Compensation: $170,000-$230,000 base + equity
Location: San Francisco, CA or (open to remote to start)
About Our Client
Our client has built a leading AI-powered clinical documentation platform for home health, used daily by thousands of clinicians and reducing documentation time by 80%+. By giving clinicians their time back, the platform helps home health organizations deliver better care to older adults who want to remain at home.
The company is growing quickly, backed by top-tier investors, and shipping new capabilities into real clinical workflows every week. They're now hiring a Senior Backend Engineer to scale the core services that power the platform and build new Generative AI / LLM-driven workflows clinicians will rely on every day.
The Role
This is a backend-heavy role for an engineer who enjoys solving real production problems: scalability, reliability, data integrity, and building practical AI-enabled workflows that directly support patient care.
What You'll Do
  • Ship complex backend services using FastAPI with MongoDB and/or Postgres
  • Build APIs and infrastructure that interface with LLMs and Generative AI models
  • Leverage AI-assisted development tools (e.g., ChatGPT/Copilot-style tooling) to increase engineering velocity without sacrificing quality
  • Prototype MVPs quickly, then harden them into secure, scalable, reliable production systems
  • Improve backend architecture, observability, and code quality standards
  • Deploy and operate services using Docker and AWS
  • Collaborate with senior engineers and mentor junior developers as the team scales

What Our Client Is Looking For
Must-Have Qualifications
  • 7+ years of professional software engineering experience with deep backend expertise
  • Startup experience shipping real features in high-growth environments
  • Experience designing distributed systems and/or data-heavy backend architectures
  • Experience working with Generative AI / LLM-powered systems in production or a strong desire to learn and build in this space
  • Strong product mindset and comfort partnering with cross-functional teams
  • Ability to operate in ambiguity and move quickly without sacrificing quality
  • High standards for reliability, clarity, and maintainability when real users depend on your code

Why Join
  • Platinum health, dental, and vision insurance
  • Flexible PTO
  • Opportunity to be at the forefront of LLM innovation in healthcare
  • Founded by AI researchers (Cornell and Amazon Alexa backgrounds)
  • Direct impact on clinicians and patients-software that meaningfully improves care delivery
  • Mission-driven team backed by strong AI talent and reputable investors

If you want, I can also produce a tight LinkedIn version + a screening scorecard (must-have signals, interview questions, red flags) specifically for Senior Backend + production LLM experience.
