Principal Software Engineer

Principal Software Engineer (Technical Executive)

Fully remote “builder” role spanning the full technology stack—driving architecture, product delivery, and system reliability through hands-on execution.

Responsibilities

• Build and ship features across the stack: frontend interfaces, backend services, data layers, and AI-powered capabilities
• Design and implement architecture: service boundaries, data models, caching strategies, and infrastructure topology
• Own production systems end-to-end: diagnose and resolve issues across application servers, job workers, databases, and distributed systems
• Integrate AI capabilities into production: prototype, evaluate models, and deploy behind scalable APIs
• Develop and optimize data/ML pipelines: model training workflows and inference systems (performance, cost, scalability)
• Build payment & billing systems: subscription logic, webhook processing, and financial reconciliation
• Contribute across all layers: database migrations, API design, UI components, testing, and deployment workflows
• Establish engineering best practices for code quality, testing, and documentation
• Mentor and support engineers to unblock complex technical challenges

Requirements

• 8+ years shipping complex production systems
• Strong full-stack expertise: modern frontend frameworks, backend APIs, database design, and infrastructure management
• Proven ability to work across UI → backend → infrastructure
• Hands-on experience integrating AI/ML into production (model serving and inference pipelines)
• Experience building systems handling financial transactions (payments, subscriptions, reconciliation)
• Deep production experience: debugging performance, analyzing logs/metrics, maintaining reliability at scale
• Ability to design and scale systems under growing demand; strong system design skills and tradeoff evaluation
• Can operate independently and take ownership of high-impact decisions

Nice to Have

• Workflow orchestration / distributed job processing systems
• Self-managed infrastructure experience
• Experience with media/creator platforms or content-heavy systems
• Experience with cryptocurrency or alternative payment systems

Technology Stack (provided)

• React, Next.js, TypeScript, Tailwind CSS
• Node.js/NestJS, Prisma, PostgreSQL, Redis
• Temporal, Docker, Linux, plus cloud/storage platforms
• Python/PyTorch for AI pipelines
• Monitoring/observability and CI/CD tooling

Compensation

Typically $195K–$215K depending on experience.
