What is the difference between Junior Fastapi Developer vs Junior Python Developer?

AspectJunior Fastapi DeveloperJunior Python Developer
Required CredentialsBasic Python knowledge, familiarity with FastapiBasic Python knowledge, possibly some frameworks
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?

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 is a Junior FastAPI Developer?

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

hatch I.T. is partnering with Expression to find a Senior AI Software Engineer. See details below:

About The Role:

Expression is seeking an experienced Senior AI Software Engineer and Technical Lead to lead the development of a prototype platform that performs intelligent data processing, distributed inference, and resilient edge computing in communication-constrained environments. The platform integrates software-defined radio (SDR) technologies, edge AI, distributed systems, and modern software engineering practices to enable autonomous processing and decision support at the tactical edge.

The ideal candidate is an experienced hands-on engineer who enjoys building complex systems from the ground up. You are equally comfortable designing system architecture, writing production-quality code, integrating hardware and software components, and mentoring other engineers while remaining deeply involved in implementation.

Security Clearance: Eligible to obtain Secret or Top Secret Clearance (U.S citizenship required)

About the Company:

Founded in 1997 and headquartered in Washington DC, Expression provides data fusion, data analytics, software engineering, information technology, and electromagnetic spectrum management solutions to the U.S. Department of Defense, Department of State, and national security community. Expression's "Perpetual Innovation" culture focuses on creating immediate and sustainable value for their clients via agile delivery of tailored solutions built through constant engagement with their clients. Expression was ranked #1 on the Washington Technology 2018's Fast 50 list of fastest growing small business Government contractors and a Top 20 Big Data Solutions Provider by CIO Review.

Responsibilities:
  • Lead the technical architecture and implementation of an edge-native intelligent processing platform supporting distributed sensing, edge inference, and resilient mission operations.
  • Design scalable software architectures supporting heterogeneous edge computing devices, software-defined radios, embedded compute platforms, and cloud-enabled mission services.
  • Develop high-performance backend services using Python, FastAPI, asynchronous programming, and modern distributed software engineering techniques.
  • Lead integration of Software Defined Radio (SDR) platforms (such as Ettus USRP, GNU Radio, or equivalent SDR ecosystems) into software pipelines for real-time data processing and analytics.
  • Design resilient distributed processing frameworks capable of operating under degraded, disconnected, intermittent, and bandwidth-constrained communications.
  • Develop intelligent data processing pipelines that reduce communication overhead through feature extraction, prioritization, and adaptive data management.
  • Design peer-to-peer communication services supporting decentralized collaboration across heterogeneous edge devices.
  • Implement secure synchronization, workload distribution, and fault-tolerant processing across multiple edge computing nodes.
  • Lead software integration across embedded Linux systems, containerized services, edge compute devices, and cloud infrastructure.
  • Establish software architecture standards, CI/CD pipelines, testing frameworks, DevSecOps practices, and engineering best practices.
  • Collaborate closely with AI engineers to integrate machine learning inference capabilities into production software.
  • Produce technical documentation, software architecture artifacts, interface specifications, and engineering design documentation.
  • Support technical demonstrations, customer engagements, and prototype evaluations.
  • Mentor junior engineers while maintaining significant hands-on software development responsibilities.
Qualifications:
  • Bachelor degree in Computer Science, Software Engineering, Electrical Engineering, Data Science, or related fields. An advanced degree is preferred.
  • 10+ years of professional software engineering experience designing and building distributed software systems.
  • Demonstrated experience serving as technical lead of complex software development efforts.
  • Strong Python experience including, asyncio and asynchronous programming, FastAPI, Pydantic, type hinting, and modern development practices.
  • Experience developing distributed systems, microservices, or event-driven architectures.
  • Proven experience implementing retrieval architectures.
  • Experience deploying applications using Docker and cloud-native services within AWS or Azure.
  • Experience implementing CI/CD pipelines using GitLab CI, GitHub Actions, or similar automation platforms.
  • Experience with Kubernetes, Infrastructure as Code (Terraform and Helm, or equivalent), and modern cloud-native deployment practices.
  • Experience integrating hardware and software systems.
  • Experience designing resilient software systems capable of operating under degraded or intermittent network conditions.
  • Strong written and verbal communication skills with the ability to produce technical documentation and communicate effectively with technical and executive stakeholders.
Preferred Qualifications:
  • Experience with Software Defined Radio (GNU Radio, USRP, Ettus, SoapySDR, UHD, etc.)
  • Experience developing edge computing applications.
  • Experience with embedded Linux.
  • Experience supporting DoD, Intelligence Community, or Federal programs.
  • Experience with distributed data synchronization technologies.
  • Experience with low-latency data processing pipelines.
  • Experience working with autonomous systems, ISR, electronic warfare, or sensor fusion applications.
  • Experience integrating AI/ML inference into operational software systems.
  • Experience supporting National Security or Federal Civilian customers.
