Commission Backend Developer Python Jobs in Oregon

Overview

LMI is looking for a mid-level Full Stack Developer to help build and extend a portfolio of mission applications for a DoD customer on a DoD-accredited cloud platform in AWS GovCloud. You'll be an early member of a small, cross-functional application team working alongside an HCD researcher and a front-end developer to deliver mission tools that operate up to and including IL6 environments.

This isn't a maintain-the-backlog role. You'll own the API, authentication, and data connectivity layer between the application and the backend data platform, and you'll help shape how that integration pattern gets built for successive applications as the portfolio grows.

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.

This position requires an active Secret DoD clearance. This is a 100% remote role.

Responsibilities

What You'll Do

• Own the API, authentication, and data connectivity layer, designing and implementing RESTful services that connect mission applications to a backend data platform built on AWS GovCloud
• Build and ship full stack features across the application layer, working closely with the front-end developer who owns the UI implementation
• Integrate with backend data services including relational databases (Aurora or Amazon RDS), AWS Lambda-based processing pipelines, and AWS Glue
• Design and implement role-based access control, session management, and authentication patterns appropriate for environments up to IL6
• Collaborate directly with the HCD researcher and front-end developer in working sessions, shaping technical decisions that affect user experience rather than just implementing specs
• Contribute to backend architecture decisions across successive application builds, establishing repeatable integration patterns for the application portfolio

Qualifications

What We're Looking For

• Active Secret clearance
• 3+ years of full stack development experience; comfortable owning both backend services and application-layer integration
• Solid backend experience in Node.js and/or Python
• Experience designing and developing RESTful APIs and backend services that support scalable, maintainable integration across distributed application components
• Experience with relational databases; PostgreSQL, MySQL, Aurora, or Amazon RDS and including schema design, SQL development, and operational support
• Familiarity with AWS services relevant to application integration: API Gateway, Lambda, IAM, S3, RDS/Aurora, and related GovCloud services
• Experience implementing authentication and role-based access control in web applications
• Ability to move fast and iterate without heavy specs or detailed tickets

What Will Set You Apart

• Experience developing software in DoD or IC environments governed by federal security and compliance requirements, secure coding practices, access control, auditability, and deployment constraints in accredited systems
• Hands-on experience with AWS GovCloud, understanding of service availability differences, compliance boundaries, and GovCloud-specific constraints
• Experience building on IL4 or IL6 platforms, or familiarity with DoD Impact Level requirements and how they shape application architecture decisions
• Prior work alongside HCD or UX teams, experience translating validated design direction into application behavior rather than working from static mockups alone
• A portfolio of side projects, open-source contributions, or other evidence of a builder's disposition; we care more about what you've built than where you've worked
• SOF operator or SOF-support background with understanding of SOF core activities and mission sets
