Overview

At LMI, we build mission-ready software solutions that make a difference. Our Field Software Engineers work directly with government partners to deliver secure, scalable applications that accelerate decisions, streamline operations, and support some of the nation's most critical missions.

Like a startup CTO in the field, you'll wear many hats : part backend developer, part full-stack engineer, part problem solver. You'll operate with autonomy, adapt to shifting requirements, and bring technical clarity to ambiguous problems-all while collaborating with mission stakeholders, data scientists, and the Chief Product Officer team. If you thrive at the intersection of customer impact, technical excellence, and operational speed, this role offers the chance to deliver software that matters.

This role requires an ActiveTS / SCI security clearance and availability to collocate with our defense and national security customers in the Pentagon.

LMI is a new breed of digital solutions provider dedicated to accelerating government impact with innovation and speed. Investing in technology and prototypes ahead of need, LMI brings commercial-grade platforms and mission-ready AI to federal agencies at commercial speed.

Leveraging our mission-ready technology and solutions, proven expertise in federal deployment, and strategic relationships, we enhance outcomes for the government, efficiently and effectively. With a focus on agility and collaboration, LMI serves the defense, space, healthcare, and energy sectors-helping agencies navigate complexity and outpace change. Headquartered in Tysons, Virginia, LMI is committed to delivering impactful results that strengthen missions and drive lasting value.

Responsibilities

Own technical delivery : Design and implement software solutions across multiple government deployments, from first prototype to stable mission use.

• Embed with customers : Partner with mission stakeholders to understand requirements, translate needs into technical approaches, and deliver capabilities that directly support operations.
• Full-stack development : Build and maintain scalable applications using Python, JavaScript / TypeScript, React, Node.js, and modern web frameworks.
• Backend architecture : Develop and optimize APIs, databases, and cloud-based services to support secure, high-performance mission applications.
• Deliver clarity under ambiguity : Scope projects, remove blockers, and make informed trade-offs between speed, scope, and quality.
• Contribute directly in code : Write and review production-grade software across backend and full-stack environments when clarity or momentum depends on it.
• Codify patterns : Capture reusable workflows, best practices, and lessons learned into playbooks, tools, and building blocks that scale beyond a single project.
• Shape the roadmap : Share field signal with LMI's product and research teams to guide the evolution of our engineering practices and software platforms.
