Overview of Opportunity 

Two Six Technologies is actively seeking a Lead Full Stack Developer to join our team. The team is composed of intellectual individuals, passionate about developing reverse engineering tooling, system architecture, technical leadership, and complex software implementation. The team is growing and looking for someone with a full-stack background who has an understanding of how to synthesize program requirements into actionable tasks and lead technical teams through implementation and scaling. If you are actively using modern frontend frameworks, Python, and cloud-based architectures, the team wants to talk to you!

What you will do:

• Serve as a technical lead, bridging the gap between high-level visionary goals and tactical implementation for critical national security research programs.


• Support the Principal Investigator by breaking down complex deliverables into actionable tasks and overseeing the full stack development process from inception to deployment.


• Lead technical implementation teams 100% in-office, with a primary focus on hands-on lab operations in Arlington and occasional travel to Herndon.


• Ensure the successful completion of program deliverables through sound technical judgment and the leadership of functional engineering staff.

What you will need (basic qualifications)

• Bachelor’s degree in Computer Science or a related field and 7+ years of experience in a similar software engineering role (extensive experience in Software Engineering, Computer Science, or related field may substitute for a specific degree).

• Advanced proficiency in development programming languages such as Python and JavaScript, with extensive experience working in Linux-based environments.


• Deep understanding of the software development lifecycle, including version control (git), containerization and scaling (Kubernetes), and CI/CD automated tools (Jenkins, GitLab).


• Must possess an active Top Secret (TS) clearance with SCI eligibility and be willing to work 100% in person and in a lab environment.


• This role is based in-person at our Arlington, VA office, with a planned transition to our Herndon, VA lab facility in the future. Candidates must be able to commute to both locations.

Nice to have (preferred)

• Experience designing and deploying scalable applications within AWS, OpenStack, or other cloud-based architectures.


• Strong professional experience with modern frontend frameworks, specifically Vue.js.


• Familiarity with Infrastructure-as-Code practices and tools such as Ansible, Terraform, or OpenTofu to optimize service delivery.


• Prior experience supporting DoD or national security R&D projects, particularly in transitioning technology to operational end-users.


• Demonstrated success in providing technical mentorship and guidance to junior and staff-level engineering staff.

Security Clearance:
