Principal Full Stack Developer information

What is a principal full stack developer?

A Principal Full Stack Developer is a senior-level software engineer who leads the design, development, and implementation of complex web applications across both front-end and back-end technologies. They possess deep expertise in multiple programming languages, frameworks, and cloud platforms, and often set technical direction and standards for their teams. Principal Full Stack Developers also mentor other engineers, collaborate with stakeholders, and ensure that solutions are scalable, secure, and maintainable. Their role is critical in bridging the gap between business requirements and technical solutions.

What are the key skills and qualifications needed to thrive as a principal full stack developer?

To thrive as a Principal Full Stack Developer, you need advanced expertise in both front-end and back-end development, strong coding abilities in languages like JavaScript, Python, or Java, and a track record of leading technical projects. Mastery of frameworks (such as React, Angular, Node.js), cloud platforms (AWS, Azure), and version control systems (Git), along with relevant certifications, are commonly required. Exceptional problem-solving, leadership, and communication skills help you mentor teams and drive architectural decisions. These abilities are critical for delivering robust, scalable software solutions and leading development teams effectively.

What are some common challenges faced by principal full stack developers when leading cross-functional teams?

Principal Full Stack Developers often face the challenge of balancing technical leadership with effective communication across diverse teams, such as frontend, backend, and DevOps. They are responsible for aligning various stakeholders, resolving architectural disagreements, and ensuring that project goals are met on time. Navigating differences in technical expertise and priorities requires strong interpersonal skills and the ability to mentor team members while upholding best practices. Additionally, they must stay updated with evolving technologies to make informed decisions that impact the whole stack.

What is the difference between Principal Full Stack Developer vs Senior Full Stack Developer?

In contrast, the Senior Full Stack Developer primarily executes development tasks, supports team members, and contributes to project delivery. Both roles require strong technical skills, but the Principal role emphasizes leadership and vision.

Job description

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 degree requirement).
  • Proven ability to lead the planning and execution of technical tasks, including task prioritization, schedule management, and providing direction to other team members.
  • 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:

  • Must possess an active Top Secret (TS) clearance with SCI eligibility
