Overview: Lead Full-Stack Engineer Salary: $150,500-$178,000
We are seeking a
Lead Full-Stack Engineer with deep, hands-on expertise in
Next.js and Express.js to drive the development of a B2B e-commerce platform preparing for launch. This role is for a
highly technical individual contributor who owns complex problems end-to-end and leads primarily through
direct implementation and architectural decision-making, not task delegation.
You will work across the entire stack-from event-driven, React-based front-end experiences to secure, compliance-aware API logic-ensuring correctness, performance, and strict data-visibility enforcement in a regulated environment.
This position is ideal for a developer who prefers to stay
close to the code, takes personal responsibility for technical outcomes, and sets the technical bar for others through example.
Key ResponsibilitiesHands-On Technical Ownership - Serve as the primary technical owner of the platform's core functionality.
- Design, implement, and refine system architecture with a focus on correctness, security, and scalability.
- Make high-impact technical decisions and directly implement critical paths rather than delegating them.
- Review code and provide technical guidance to other engineers as needed, without functioning as a people manager.
Full-Stack Development - Build and optimize the Next.js front end, including:
- React-based, event-driven UI patterns
- Server-side and client-side rendering strategies
- Component architecture, performance tuning, and state management
- Design, build, and maintain Express.js backend services, including:
- API routing and request handling
- Dataset retrieval driven by dynamic parameters
- Robust data validation and error-handling strategies
Platform & Data Integrity - Implement and enforce granular access-control logic, ensuring correct user- and customer-specific data visibility.
- Own data correctness across all API responses and business workflows.
- Collaborate closely with QA and product to ensure strong test coverage, edge-case handling, and predictable system behavior.
Security & Compliance - Develop in alignment with CMMC objectives and secure-by-design principles.
- Ensure compliant handling of ITAR-controlled data across two operational sites.
- Implement secure coding practices, logging, monitoring, and auditability to support compliance and production readiness.
Collaboration & Delivery - Partner with product management and stakeholders to translate requirements into robust technical solutions.
- Drive the platform toward production readiness and launch through direct execution.
- Coordinate with DevOps on environments, deployment pipelines, and operational reliability while maintaining a strong development focus.
QualificationsRequired - 5+ years of hands-on full-stack development experience with strong proficiency in:
- Next.js (React-based)
- Node.js & Express.js
- Demonstrated ability to personally design and implement complex systems, not just oversee them.
- Strong experience with:
- Event-driven UI patterns
- REST API design and integration
- Secure data handling and fine-grained access-control logic
- High attention to detail, particularly around data correctness, authorization, and edge cases.
- Proven delivery of production-ready web applications.
- Clear communicator who can influence technical outcomes through code and technical reasoning.
Preferred - Experience working in regulated or security-focused environments.
- Familiarity with:
- CMMC compliance frameworks
- ITAR data handling requirements
- Experience with B2B, enterprise, or multi-tenant platform design.
- Strong working knowledge of relational databases (e.g., PostgreSQL, SQL Server).
- Exposure to cloud platforms such as Azure or AWS.
Nice-to-Have - Experience implementing RBAC or ABAC models.
- Knowledge of event-driven backend patterns (queues, workers).
- Practical DevOps familiarity (CI/CD, containerization, infrastructure as code).
