Lead Full-Stack Developer
Remote
This role supports a federal client and requires the ability to obtain a public trust clearance. No sponsorship is available.
We are seeking a Lead Full-Stack Developer to support a major federal modernization initiative focused on building secure, scalable, cloud-native applications on AWS. This is a remote, hands-on technical leadership role for someone who can lead architecture, mentor developers, define technical standards, and still contribute directly to full-stack engineering.
What You Will Do:
• Lead and mentor full-stack development teams supporting cloud modernization, product development, and solution architecture initiatives.
• Provide hands-on full-stack engineering and architectural oversight for secure, scalable, distributed applications built on AWS.
• Design and implement frontend and backend services using Python, JavaScript, Django, Vue.js, REST APIs, microservices, containers, and AWS-native services.
• Collaborate with clients, solution architects, product owners, UX designers, business analysts, platform engineers, and development teams to deliver resilient software products that meet functional and non-functional requirements.
• Define application architecture standards, development best practices, design patterns, and technical roadmaps across complex modernization projects.
• Ensure solutions align with AWS Well-Architected Framework principles, modern CI/CD practices, API-first design, event-driven architecture, and cloud-native engineering standards.
• Lead technical decision-making, evaluate design tradeoffs, provide escalation support, and guide implementation across multiple concurrent initiatives.
• Support proof-of-concept development, technical demonstrations, proposal efforts, RFP responses, and technical thought leadership.
What You Will Need:
• Ability to obtain a public trust clearance.
• No sponsorship available.
• Minimum of 8 years of relevant full-stack application development experience, including at least 4 years in technical leadership, architecture, or team lead roles.
• Bachelor’s degree required, or 12 years of relevant experience in lieu of a degree.
• Strong hands-on experience with Python and JavaScript.
• Experience leading or mentoring teams of 5 or more developers.
• Experience building frontend and backend services for cloud-native software products.
• Django experience preferred; Flask, FastAPI, Falcon, or SQLAlchemy may be considered as alternatives.
• Vue.js experience preferred; React, Svelte, or Angular 1.6+ may be considered as alternatives.
• Experience with microservices architecture, REST API design, Docker or Kubernetes, serverless computing, and CI/CD for enterprise applications.
• Familiarity with AWS SAM and design patterns such as MVC, Circuit Breaker, and Event-Driven Architecture.
• Ability to design, build, test, deploy, and architect custom AWS cloud applications.
• Strong understanding of Agile and Scaled Agile software delivery practices.
• Excellent communication skills, including the ability to explain technical tradeoffs to technical and non-technical stakeholders.
What Would Be Nice to Have:
• AWS Certified Solutions Architect – Professional.
• AWS Certified Developer – Associate.
• Experience with AWS Lambda, API Gateway, Step Functions, EventBridge, EKS/Kubernetes, RDS PostgreSQL, MongoDB, Redis, Memcached, Elasticsearch, Docker, and modern monitoring/observability tools.
• Experience supporting technical proposals, white papers, RFPs/RFIs, or consulting solution architecture efforts.
• Experience with performance tuning, capacity planning, and operational resilience for large-scale distributed systems.
• Contributions to open-source projects, technical publications, or cloud-native development thought leadership.
