Vantor is forging the new frontier of spatial intelligence, helping decision makers and operators navigate what’s happening now and shape what’s coming next. Vantor is a place for problem solvers, changemakers, and go-getters—where people are working together to help our customers see the world differently, and in doing so, be seen differently. Come be part of a mission, not just a job, where you can: Shape your own future, build the next big thing, and change the world.

To be eligible for this position, you must be a U.S. Citizen. This position requires an active U.S. Government security clearance, applicants who do not currently hold the required clearance will not be eligible for consideration. Employment for cleared roles is contingent upon verification of clearance status.

Please review the job details below.

This position requires an active U.S. Government Security Clearance at the TS/SCI level with required polygraph.

We are seeking a Full Stack Developer with a strong frontend and data-integration focus to support the development of a mission-critical, web-based application used for data ingest, analytics, visualization, and dissemination. This role emphasizes building intuitive user interfaces backed by robust APIs and data-processing services in a fast-paced, customer-facing environment.

Responsibilities:

Collaborate with government stakeholders and product leadership to refine and document application requirements.
Design and implement modern, responsive user interfaces using Angular or comparable frameworks (React or Vue).
Build and integrate backend APIs using Node.js (Nest.js) and Python-based analytics services.
Integrate external data sources, analytics libraries, and query engines to support complex workflows.
Partner with UI/UX designers and power users to deliver intuitive, data-driven user experiences.
Participate in Agile development activities including sprint planning, daily standups, demos, and retrospectives.
Test and validate features to ensure functional, performance, and usability requirements are met.

Minimum Qualifications:

Bachelor’s degree in Computer Science or related technical field.
5+ years of professional software development experience.
Strong experience with modern frontend frameworks (Angular preferred; React or Vue acceptable).
Experience using UI component libraries (PrimeNG preferred) and/or Tailwind CSS.
Backend API development experience using Node.js (Nest.js or similar).
Experience integrating Python-based analytics or data processing services.
Hands-on experience with relational databases, particularly PostgreSQL.
Experience building and deploying applications in AWS environments.
Willingness to work onsite full time.

Preferred Qualifications:

Experience with data visualization and analytical presentation of results.
Familiarity with pandas or polars for data processing.
Experience with Trino or distributed query engines.
Experience implementing authentication and authorization in cloud-based systems.
Familiarity with Docker-based development workflows.

Pay Transparency: In support of pay transparency at Vantor, we disclose salary ranges on all U.S. job postings. The successful candidate’s starting pay will fall within the salary range provided below and is determined based on job-related factors, including, but not limited to, the experience, qualifications, knowledge, skills, geographic work location, and market conditions. Candidates with the minimum necessary experience, qualifications, knowledge, and skillsets for the position should not expect to receive the upper end of the pay range.

The base pay for this position within the Washington, DC metropolitan area is: $113,000.00 - $188,000.00 annually.

For all other states, we use geographic cost of labor as an input to develop market-driven ranges for our roles, and as such, each location where we hire may have a different range.

Benefits: Vantor offers a competitive total rewards package that goes beyond the standard, including a robust 401(k) with company match, mental health resources, and unique perks like student loan repayment assistance, adoption reimbursement and pet insurance to support all aspects of your life.
