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.
