What does a Junior Python Flask Developer do?

A Junior Python Flask Developer assists in building web applications using the Flask framework and Python programming language. Their responsibilities typically include writing and maintaining code, debugging applications, working with databases, and collaborating with senior developers and designers. They are often involved in both the backend and parts of the frontend, helping to implement new features and ensure the application runs smoothly. This role is ideal for those who are early in their software development career and looking to gain hands-on experience in web development.

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

To thrive as a Junior Python Flask Developer, you need a solid understanding of Python programming, web development concepts, and familiarity with the Flask framework, typically supported by a relevant degree or coursework. Experience with tools such as Git for version control, RESTful APIs, and basic front-end technologies (HTML, CSS, JavaScript) is also important. Strong problem-solving skills, eagerness to learn, and effective communication help you collaborate with team members and adapt to new challenges. These skills and qualities are crucial for building robust web applications, contributing effectively to projects, and growing in a fast-paced tech environment.

What are some common challenges faced by Junior Python Flask Developers when working on team-based projects?

As a Junior Python Flask Developer, one common challenge is adapting to established codebases and adhering to team coding standards. Collaborating with senior developers often means integrating your work with theirs, requiring clear communication and frequent code reviews. Additionally, balancing the need to learn new frameworks or tools while delivering features on tight deadlines can be demanding. However, support from experienced team members and regular feedback sessions help foster growth and ensure successful project contributions.

Job description

Position Title: Full Stack Python Developer 
Job ID#: 26-1106
Clearance: Secret 
Location: Herndon, VA

What You’ll Do:
Navitas is seeking a Full Stack Python Developer to build and scale user-facing and backend applications that power AI/ML capabilities for the DoD Search Portfolio.
You will develop secure, cloud-native web services and UI experiences that integrate with LLM/RAG and semantic search pipelines. This role partners closely with ML engineers and data teams to productionize models through robust APIs, workflows, and operational tooling. You will help deliver mission-ready solutions that handle large-scale datasets with strong performance, reliability, and traceability.
The ideal candidate thrives in fast-paced environments and enjoys building end-to-end systems that make AI usable for real users.

Responsibilities will include but are not limited to:

  • Support CI/CD and DevOps practices (containerization, deployment automation, monitoring/alerting) to ensure stable releases and operational readiness.

  • Apply best practices for security, logging, auditing, and compliance aligned with federal/DoD standards across services and environments.

  • Design and develop Python backend services and REST APIs (e.g., Flask/FastAPI) to expose AI/ML and search capabilities to applications and mission systems.

  • Build full stack features (UI + API) that support search workflows, semantic retrieval, and results visualization for enterprise users.

  • Integrate backend services with Databricks/Spark pipelines and ML workflows to enable scalable inference, data processing, and batch/stream execution.

  • Implement and maintain integrations with Elasticsearch (search/indexing) and Neo4j (graph/relationship-driven experiences) to enhance relevance and discovery.

  • Collaborate with ML Engineers to productionize LLM/RAG-based features, including prompt/inference orchestration, embeddings services, and retrieval workflows.

  • Create clear technical documentation and communicate design decisions, trade-offs, and implementation approaches to both technical and non-technical stakeholders.

What You’ll Need:

  • Bachelor’s degree (or equivalent experience) with 5+ years in software engineering focused on Python and web application development.

  • Must have: Strong hands-on experience building Python APIs/services (Flask/FastAPI preferred) and integrating with databases, search platforms, and external systems.

  • Experience developing full stack applications using modern front-end frameworks (React/Angular/Vue) plus strong API design skills.

  • Familiarity with AI/ML concepts and integrations (LLMs, embeddings, semantic search, RAG workflows) and working closely with data/ML teams.

  • Must have: Working experience with cloud-native delivery (Docker/Kubernetes), CI/CD, Git-based workflows, and performance/reliability best practices; Databricks/Spark experience required.
