Original job description

Overview

LMI is seeking a talented and motivated Full Stack Software Engineer to join the team developing and advancing RAPTR®, LMI's innovative modeling, simulation, and analysis platform. RAPTR enables federal defense and national security customers to make faster, more informed decisions through advanced analytics, interactive visualizations, and rapid modeling and simulation capabilities.

As a Full Stack Software Engineer on the RAPTR team, you will play a critical role in designing, developing, integrating, and deploying scalable, secure, and high-performance software solutions that support complex mission requirements. You will work across the full technology stack, building intuitive web applications, robust backend services, and data-driven capabilities that transform complex information into actionable insights.

The ideal candidate is a technically strong, adaptable engineer who thrives in a fast-paced, collaborative environment, takes ownership of challenging problems, and is passionate about delivering innovative technology to support critical government missions. This position offers the opportunity to directly influence product capabilities, contribute to technical decisions, and work closely with customers and multidisciplinary teams to deliver meaningful mission impact.

This is a remote role. This position requires the ability to obtain a CBP BI clearance. You must be a U.S. citizen.

Responsibilities

Responsibilities:

Design, develop, and maintain scalable, secure, and high-performance full-stack applications supporting RAPTR's modeling, simulation, and analytics capabilities.
Build and enhance intuitive, responsive user interfaces using modern frontend frameworks such as Angular and React, delivering seamless user experiences and interactive data visualizations.
Develop and integrate robust backend services, RESTful APIs, and data pipelines using Python, Node.js, TypeScript, and PostgreSQL.
Collaborate with cross-functional teams, including software engineers, data scientists, product managers, and government stakeholders, to translate complex mission requirements into innovative technical solutions.
Support application deployment, automation, and continuous integration and delivery (CI/CD) processes using Docker, GitLab, and cloud infrastructure, including AWS GovCloud.
Troubleshoot complex technical challenges, optimize application performance, and implement secure coding practices to ensure reliability, scalability, and compliance with federal security requirements.
Contribute to technical architecture decisions, software design reviews, and product enhancements to continuously improve RAPTR's capabilities and support evolving customer needs.
Engage directly with government customers to understand operational challenges, gather feedback, and deliver software solutions that drive measurable mission impact.

Qualifications

Must be able to obtain and maintain a favorable U.S. Customs and Border Protection (CBP) Background Investigation (BI) determination.
Advanced proficiency in Python.
Extensive experience with PostgreSQL, including database development and management.
Proven experience with the MEAN stack and full-stack application development using TypeScript.
Experience developing modern web applications using Angular or React.
Experience developing backend services using server-side frameworks such as Node.js or equivalent technologies.
Experience designing, developing, and integrating RESTful APIs to support frontend applications and external data sources.
Strong knowledge of containerization technologies, such as Docker, and CI/CD pipelines using GitLab.
Familiarity with cloud deployment models, particularly AWS GovCloud, and/or experience working within DoD or federal environments.
Demonstrated ability to integrate software solutions with existing business processes, systems, and APIs.
Strong understanding of the software development lifecycle (SDLC), secure coding practices, and software security principles.
Ability to effectively manage multiple tasks, balance competing priorities, and deliver results in a fast-paced environment.
Demonstrated ability to work independently, take initiative, and operate with significant autonomy in dynamic environments.
Willingness and availability to travel to client sites as needed.

Preferred Qualifications

Current favorable U.S. Customs and Border Protection (CBP) Background Investigation (BI) determination.
Experience supporting federal government customers, with an understanding of their unique mission needs, operational challenges, and requirements.
Demonstrated ability to develop strategic relationships with key stakeholders and foster long-term customer partnerships.
Ability to clearly communicate complex technical concepts and articulate the value of software solutions to non-technical audiences.
Ability to provide strategic input on product enhancements and development priorities based on market trends and customer feedback.

Experience developing and maintaining continuous integration and continuous deployment (CI/CD) pipelines using tools such as GitLab.
Familiarity with container orchestration technologies, including Kubernetes and platforms such as EKS, AKS, GKE, Kops, or OpenShift.
Strong working knowledge of Unix/Linux operating systems.
Knowledge of AWS services and cloud capabilities, particularly within AWS GovCloud environments.
