Senior Full Stack Developer Python, React & AI

Senior Full Stack Developer Python + React + AI

Senior Full Stack Developer for an established organization building high-traffic digital products used by a broad national audience.

First things first: we need strong professional experience with both Python and React. (For Python, we mean writing production Python code for applications and backend services, not primarily scripting or automation.)

If you're a strong developer who wants to find a place to stay, grow, and do great work with people you enjoy, please read on. This is an unusually long-tenured, collaborative team, so we’re looking for someone who values that kind of stability, likes owning what they build, thinks beyond the ticket in front of them, enjoys solving problems, and is curious about how AI can make good developers even better.

The engineering team has a lot of autonomy and relatively little bureaucracy. Developers work directly with product owners and other stakeholders and typically see what they build through from idea to development, testing, launch, and ongoing improvement.

The technology environment includes Python, React, JavaScript, cloud technologies, databases, modern data tools, and AI-assisted development.

What You’ll Do

Build and improve full stack applications using Python on the backend and React on the front end

Design, write, test, and maintain production Python application code

Build and evolve user-facing features in React

Work across JavaScript, databases, APIs, and cloud technologies

Use AI-assisted development tools and automation as part of your everyday workflow

Collaborate directly with product managers, designers, analysts, testers, and other developers

Help make architecture and technical design decisions

Write clean, efficient, maintainable code

Review code and help improve overall engineering quality

Mentor other developers while remaining hands-on

Own meaningful work from development through launch and continued improvement

What We’re Looking For

You should have:

3+ years of professional full stack software development experience

Strong professional experience writing production Python code for applications and backend services

Strong React experience building production web applications

Modern JavaScript / ES6

HTML and modern CSS

Experience with relational databases such as PostgreSQL

Git/version control

Comfort working in Linux, macOS, or another Unix-based environment

Experience incorporating AI-assisted development tools or automation into your development workflow

Bachelor’s degree in computer science or a related field

You do not need every technology on the list, but Python and React are both important for this role.

If your Python experience has primarily been scripting, automation, or data analysis rather than building production applications, this particular position probably isn’t the right match.

Nice to Have

AWS or another cloud platform

CI/CD tools such as Jenkins

Data ingestion or transformation experience

Cloud-based data and analytics platforms

Experience building AI features into products

The AI Part

You do not need to be an AI/ML engineer.

We are looking for developers who are actively using AI-assisted tools in their development workflow and are interested in finding better ways to use them.

Curiosity matters here, along with the judgment to know when a tool is genuinely useful.

Why This Role

You get to stay hands-on, own meaningful work, and contribute to products that real people use.

You’ll be joining an engineering organization where strong developers are trusted to think, make decisions, experiment, and continue getting better at what they do.

This could be a particularly good fit for someone who wants to grow as a senior technical contributor without having to leave hands-on development behind.

Compensation & Benefits

Benefits include strong paid vacation, medical benefits, tuition reimbursement, training and professional development, plus additional company benefits.

Location

This is a true hybrid role based in Washington, DC or New York, with an expectation of working on-site 3–4 days per week.
