Senior Software Engineer, Front End

THE ROLE
We’re looking for a Senior Frontend Engineer who can operate with high autonomy and help shape the foundation of a new data-driven web application.
You’ll play a key role in building a data visualization and reporting platform that surfaces complex aviation datasets (airspace, flight trajectories, etc.) in a clear, intuitive, and performant way.
This role is ideal for someone who doesn’t just execute—but thinks architecturally, makes strong technical recommendations, and influences how the product gets built.
WHAT YOU’LL DO

• Design and build a modern React-based web application for data visualization and analysis
• Develop intuitive UI/UX patterns for complex, real-time aviation datasets
• Create dynamic, high-performance visualizations (e.g., airspace mapping, trajectory data)
• Collaborate closely with backend engineers working in Python and AWS-based systems
• Contribute to API design and integration (data flowing from AWS-hosted databases/services)
• Evaluate and recommend frontend frameworks, libraries, and tooling (e.g., D3.js, visualization frameworks)
• Help define frontend architecture, component structure, and best practices from the ground up
• Ensure performance, scalability, and maintainability of the application
• Operate as a senior voice on a small team—driving progress without heavy oversight

WHAT WE’RE LOOKING FOR

• 5+ years of frontend engineering experience, building modern web applications
• Strong expertise in React and modern JavaScript/TypeScript ecosystems
• Experience building data-heavy or visualization-driven applications
• Familiarity with visualization libraries (e.g., D3.js, Mapbox, or similar)
• Ability to design frontend systems—not just implement tickets
• Experience integrating with APIs and backend services (Python/AWS preferred)
• Strong understanding of performance optimization for complex UIs
• Comfortable working in a fast-moving, small team environment
• Strong communication skills and ability to collaborate cross-functionally

NICE TO HAVE

• Experience with geospatial data or mapping tools
• Familiarity with aviation, telemetry, or real-time data systems
• Exposure to AWS services (S3, ECS, SQS, etc.)
• Experience working in startup or early-stage product environments

Hiring Manager Notes: About two years ago the company went through a product pivot and is gaining some massive traction.  We need a strong full stack engineer who can help expedite some POC's that could have a massive impact on customer growth.  This person will be building out API calls to the DB which is all AWS systems.  As we are a Python shop I'd want this person to have that experience.  The big part is a very strong front end developer who can help visualize complex data (airspace, plane trajectories, and more) into a web app.  More than that since it's greenfield, someone who can make recommendations not only how to build the front end system but also any tooling/frameworks that might be advantageous. 
APiJET | Seattle, WA (remote)
APiJET is a Seattle-based leader in real-time aircraft data analytics, helping aviation companies unlock efficiency and reduce environmental impact through advanced data insights.
We’re a tight-knit, high-performing team coming out of a successful product pivot and entering a strong growth phase with increasing customer traction. As we expand, we’re investing in new product capabilities—including a modern data reporting and analytics platform.
This is an opportunity to build something greenfield, not maintain legacy code.
