A Python FastAPI Developer is responsible for designing, developing, and maintaining backend applications using FastAPI, a modern web framework for building APIs with Python. They work on creating high-performance APIs, integrating with databases, implementing authentication, and ensuring scalability. This role often involves working with asynchronous programming, cloud services, and containerization tools like Docker. Developers collaborate with teams to create efficient, secure, and well-documented API endpoints for web and mobile applications.
A Python FastAPI Developer typically spends their day designing, developing, and maintaining RESTful APIs to support web or mobile applications. This involves writing clean and efficient Python code, collaborating with frontend developers or other backend engineers to integrate new features, and ensuring the application meets performance and security standards. Developers also participate in code reviews, debugging, and continuous integration processes, while regularly communicating with product managers or stakeholders to align on project requirements. Staying up to date with FastAPI enhancements and industry best practices is also a common part of the role.
To thrive as a Python FastAPI Developer, you need strong proficiency in Python programming, experience designing RESTful APIs with FastAPI, and a background in web development concepts. Familiarity with version control systems like Git, containerization tools such as Docker, and knowledge of cloud platforms or SQL/NoSQL databases are commonly required, and certifications in cloud services or Python development can be advantageous. Excellent problem-solving skills, effective communication, and the ability to collaborate in agile teams help developers contribute efficiently to complex projects. These competencies ensure robust, scalable backend solutions and smooth coordination within development teams to meet business goals.

Ark is building the world’s highest-fidelity bioprocess simulation software to help life‑saving therapies reach patients faster. By democratizing complex AI and multi‑physics models in an intuitive software interface, we are ushering in a new era of digital bioprocessing.
With Ark, scientists can replace weeks‑long, costly ($10K–$1M+) bioreactor experiments with simulations that run in seconds. This enables researchers to explore thousands more scenarios, accelerate time to market, and ensure more medical breakthroughs make it from the lab to the world.
About the RoleArk is seeking a Fullstack Software Engineer to join our fast‑moving startup tackling some of the hardest problems in biomanufacturing. In this role, you’ll build end‑to‑end product experiences across the frontend and backend that power our digital bioprocess platform. You’ll work on performant, beautiful, and intuitive interfaces and the APIs, data models, and services that support high‑fidelity bioprocess simulations. You’ll collaborate closely with designers, engineers, and bioprocess modelers to bring complex scientific workflows to life—from browser to API to database. This is an opportunity to contribute to core product architecture and help shape the way scientists interact with high‑fidelity bioprocess simulations.
Key Responsibilities2–5 years of professional experience in software development, with meaningful work across frontend and backend. Strong proficiency with TypeScript and a modern UI framework (ideally React). Hands‑on experience with React Query / TanStack Query (or equivalent) for server‑state management—caching, invalidation, background refresh, and async workflows. Experience generating and using typed API clients from OpenAPI (or similar schema‑first approaches) in production. Backend experience in Python/FastAPI (or similar) and building reliable, well‑structured REST APIs.
