At LMI, we build mission-ready software solutions that make a difference. Our Forward Deployed 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 Active TS/SCI security clearance and availability to collocate with our defense and national security customers in the Pentagon.
