Work EnvironmentWeb backend development, API creationGeneral software development, scripting
Employer & Industry UsageTech companies, startups, web servicesBroad industry, including data analysis, automation
Common Search & ComparisonYesYes

The main difference is that a Junior Fastapi Developer specializes in building APIs using Fastapi, while a Junior Python Developer has broader Python programming skills without specific focus on web APIs. Fastapi developers typically work in web backend environments, whereas Python developers may work across various domains.

What are some typical challenges a Junior FastAPI Developer may face when joining a new team?

As a Junior FastAPI Developer, you may encounter challenges such as adapting to established codebases, understanding the team's API design patterns, and ensuring your code aligns with both FastAPI best practices and your organization's standards. Collaborating closely with senior developers and participating in code reviews can help accelerate your learning process. Additionally, you may need to quickly familiarize yourself with related tools such as Docker, Git, and testing frameworks, as well as the team's workflow for deploying and maintaining APIs in production environments.

What are the key skills and qualifications needed to thrive as a Junior FastAPI Developer, and why are they important?

To thrive as a Junior FastAPI Developer, you need foundational knowledge of Python programming, RESTful API concepts, and experience working with FastAPI frameworks, supported by a relevant degree or coding bootcamp. Familiarity with Git for version control, SQL or NoSQL databases, and containerization tools like Docker is typically expected. Strong problem-solving skills, eagerness to learn, and effective communication make candidates stand out in collaborative development environments. These competencies ensure efficient, high-quality API development and seamless teamwork in agile software projects.

What are Junior FastAPI Developers?

Junior FastAPI Developers are entry-level software engineers who specialize in building web applications and APIs using FastAPI, a modern Python web framework. They are responsible for writing, testing, and maintaining backend code, often under the guidance of more experienced developers. Their tasks typically include developing RESTful APIs, integrating databases, and ensuring application performance and security. Junior FastAPI Developers usually have a basic understanding of Python, web technologies, and REST principles. They play an important role in supporting projects, learning best practices, and growing their technical skills.

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.
