Responsibilities

• Building intuitive, responsive, and maintainable user experiences using technologies such as JavaScript, TypeScript, React, Angular, and/or Vue
• Translating design mockups, user feedback, and defined system requirements into functional and intuitive user interfaces
• Developing clean, well-tested, and maintainable code while following established engineering practices and standards
• Owning small-to-medium features from development through testing and deployment, identifying edge cases and raising risks or dependencies along the way
• Building and improving APIs and backend services that support front-end applications and system capabilities
• Developing and maintaining backend functionality using technologies such as Python, SQL, RESTful APIs, and containerized architectures
• Collaborating with QA and other engineering disciplines to understand acceptance criteria, troubleshoot defects, validate functionality, and meet functional and technical requirements
• Writing and maintaining automated unit, integration, and functional tests to validate software functionality
• Participating in code reviews, incorporating feedback, and providing constructive feedback to teammates
• Making sound engineering tradeoffs within your area of ownership and seeking additional context or guidance when appropriate
• Communicating assumptions, dependencies, and technical considerations early to minimize rework and support successful delivery
• Contributing to improvements in product usability, quality, security, performance, and maintainability

Skills

• 2–5 years of professional web or software development experience using modern development approaches
• Strong front-end development fundamentals, including an understanding of modern UI development principles, component-based architecture, responsive design, performance, and usability
• Experience with JavaScript, TypeScript, HTML, CSS, and modern front-end frameworks such as React, Angular, and/or Vue
• Experience translating designs, user needs, and defined requirements into production-quality user experiences
• Full-stack development experience with exposure to backend systems, including Python, API development and integration, application architecture, and service-to-service communication
• Experience working with relational databases and SQL, including querying and integrating data into web applications
• Experience developing, consuming, and integrating APIs between front-end applications and backend services
• Familiarity with modern containerized and microservices architectures using technologies such as Docker and Kubernetes
• Experience collaborating with QA throughout the software development lifecycle, including working with acceptance criteria, troubleshooting defects, and validating functionality
• Experience writing automated tests and developing software against defined user, functional, and technical requirements
• Understanding of software engineering best practices, including code reviews, version control, automated testing, security, performance, and maintainability
• Ability to independently own well-defined features, prioritize work, identify edge cases, and communicate risks or dependencies
• Ability to make sound engineering decisions within familiar problem areas and recognize when additional guidance or clarification is needed
• Strong communication skills and experience collaborating with engineers, end users, and cross-functional teams
• Experience developing, testing, or deploying software within air-gapped or highly secure government network environments
• Ability to hold and maintain a U.S. Government TS/SCI clearance
• While this role is remote, the potential for travel may occur such as client visits, company gatherings, and other project related travel as needed may be required
• Must be a US Citizen and be able to obtain and hold a U.S. Top Secret security clearance and be eligible to obtain and maintain a TS/SCI clearance
• This position requires eligibility to obtain and maintain a U.S. security clearance
• To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C
• • 1157, or (iv) Asylee under 8 U.S.C
• 1158, or be eligible to obtain the required authorizations from the U.S. Department of State
• Experience designing and developing intuitive user interfaces featuring real-time, 2D/3D geospatial visualizations
• Experience building software for mission-critical, defense, aerospace, or other highly secure environments
• Actively hold a U.S. Government Secret clearance
