At Expedition Technology (EXP), we're looking for a Senior Software Engineer to help design, build, and deliver mission-critical systems supporting the United States Government. This role is for engineers who think beyond writing code. Successful candidates understand that great systems require thoughtful architecture, maintainable software, reliable deployment pipelines, strong observability, and operational resilience. You are comfortable moving between application development, cloud-native platforms, deployment automation, and technical leadership as mission needs evolve. EXP is an AI-enabled engineering organization. We encourage engineers to leverage modern AI-assisted development tools such as GitHub Copilot, Claude Code, OpenCode, and similar technologies as part of their daily workflow. Successful candidates should be comfortable using these tools to improve productivity while maintaining strong technical judgment, code quality, and ownership of delivered solutions. What You'll Do: - Design and implement scalable software systems, services, and internal tools using Python and modern engineering practices - Lead architectural decisions across application, deployment, infrastructure, and operational domains - Design systems with maintainability, security, resiliency, scalability, and observability as first-class concerns - Build and improve CI/CD pipelines and deployment automation workflows - Design, deploy, and support cloud-native applications running in containerized and Kubernetes-based environments - Establish and champion engineering best practices around testing, automation, monitoring, reliability, and software quality - Collaborate with software engineers, platform engineers, and mission stakeholders to deliver complete solutions - Troubleshoot and resolve complex issues across development, deployment, and production environments - Mentor engineers and provide technical leadership across projects and teams - Contribute to verification, validation, testing, and evaluation environments supporting mission needs Skills and Experience You Bring: - U.S. Citizenship - must be a US citizen to fulfill clearance requirements - Active TS/SCI security clearance - Bachelor's degree in Computer Science, Engineering, or a related technical discipline - 8+ years of professional software engineering experience - Expertise in one or more modern programming languages and the ability to quickly become productive in new technology stacks - Strong software engineering fundamentals independent of language or framework - Experience designing and delivering production software systems - Strong background in software architecture, system integration, and distributed systems - Experience building, deploying, and supporting containerized applications - Experience deploying and operating applications in Kubernetes-based environments - Experience building CI/CD pipelines and deployment automation solutions - Experience implementing monitoring, logging, tracing, and observability capabilities - Experience operating within cloud environments such as AWS - Strong troubleshooting, communication, and technical leadership skills Preferred Qualifications: - Infrastructure-as-Code experience using AWS CDK, Terraform, CloudFormation, or similar technologies - GitLab CI/CD experience - OpenTelemetry experience - Experience supporting highly available or mission-critical systems - Experience mentoring and developing engineers - Experience incorporating AI-assisted development tools into engineering workflows ## About Expedition Technology ## Company Overview - **One-liner**: Expedition Technology (EXP) applies AI/ML, signal processing, and computer vision to deliver signals intelligence and multi-INT solutions for the U.S. defense and intelligence communities. - **Entity Type**: Private (Bootstrapped) - **Headquarters**: Herndon, Virginia, USA - **Founded**: 2013 - **Founders**: Not publicly available ## Core Business - **Primary Industries**: Defense & National Security, Artificial Intelligence, Advanced Signal Processing, Intelligence, Surveillance, and Reconnaissance (ISR/C4ISR) - **Target Customers**: U.S. Department of Defense, Intelligence Community (IC), and prime defense contractors (B2G/Enterprise) - **Mission or Purpose Statement**: Build innovative, advanced signal, image, and multi-INT solutions to solve customers’ most complex, demanding, and urgent C4ISR challenges, preserving national safety. ## Products & Services EXP is a research and development (R&D) services and product-oriented company. They do not market off-the-shelf consumer products; they develop custom, mission-focused solutions: - **Signal Processing Solutions**: Combining traditional signal processing with machine learning algorithms to process gigasamples of data at the edge and in the cloud. - **Computer Vision Solutions**: Detecting and tracking real-world objects across multiple sensing modalities, capable of performing with scarce training data. - **Deep Learning Solutions**: Researching and deploying novel neural networks for real-time, raw sensor data challenges. - **Embedded Systems Solutions**: Implementing FPGA and GPU subsystems for image and signal data classification. - **Web / Cloud / DevOps**: Building robust, secure solutions using Docker, Kubernetes, and CloudFormation with a focus on CI/CD and automation. ## Market Standing - **Valuation**: Not publicly available (private, non-VC-backed entity). - **Key Metric**: Over a decade of sustained operations (founded 2013) with a strong reputation in the defense tech sector. - **Notable Clients/Partners**: U.S. Department of Defense, Intelligence Community (IC), and prime defense contractors. The company’s work is classified and unclassified. - **Growth Signals**: Active hiring in multiple technical areas (Computer Vision, Deep Learning, Embedded Systems, Cloud) indicates consistent demand and growth. The company states their skills are “in high demand.” ## Competitive Advantages - **Deep Domain Expertise**: Specialized in a highly technical intersection of AI/ML, signal processing, and national security, creating a high barrier to entry. - **Research-Driven Culture**: Actively performs applied research to advance the state of the art, differentiating them from pure implementation contractors. - **Unique Organizational Model**: Operates as a “team of teams” using coaches instead of traditional managers, designed to foster autonomy, continuous learning, and rapid reconfiguration for specific project goals. - **Product-Oriented Mindset**: Unlike many government-services firms, EXP focuses on seeing ideas through to actualized, deployable products. ## Strategic Focus - **Continuous Research & Innovation**: Keeping pace with and pushing the boundaries of AI/ML, sensor processing, and edge computing to solve urgent national security problems. - **Talent Retention & Development**: Investing heavily in a unique coaching and benefits model to attract and keep top-tier technical talent in a competitive defense-tech labor market. - **Agile, Client-Centric Delivery**: Maintaining flexibility in project planning to meet specific, unique mission requirements of the DoD and IC. ## Why Work Here - **Unique Management Structure**: Replaces traditional “bosses” with “coaches” who advocate for career progression and connect employees to learning opportunities. Employees choose their own coach annually. - **Exceptional Benefits & Flexibility**: - **Individual Benefit Account (IBA)**: Employees receive a pool of funds to allocate as they wish across healthcare, PTO, and a bonus. Unused IBA dollars are paid out at year-end. - **Flexible Cash PTO**: Can take up to 45 days of PTO per calendar year and can cash out unused time. - **Retirement**: Up to 12% contribution to a 401(k) (employer match/profit sharing) plus student loan repayment plans. - **Parental Leave**: 12 weeks paid for primary caregivers; 2 weeks for secondary. - **Learning Culture**: Autonomy to guide careers with support from coaches. Benefits include tuition assistance, conference attendance, and internal “brown bag” discussions. - **Mission-Driven Work**: The opportunity to work on cutting-edge technology that directly impacts national security. - **Work Policy**: Likely on-site or hybrid, given the classified nature of much of the work (Herndon, VA location). - **Commitment to Accessibility**: Explicit accommodations policy for candidates with disabilities. ## Sources 1.
