Principal Engineer / Technical Executive

Principal Engineer / Technical Executive

KORE1, a nationwide provider of staffing and recruiting solutions, has an immediate opening for a Principal Engineer / Technical Executive that is fully remote.

Overview

This role is designed for a highly experienced engineer who operates across the full technology stack while driving architecture, product delivery, and system reliability. You will combine deep technical expertise with hands-on execution, owning everything from frontend experiences to backend systems, infrastructure, and AI integration.This is a builder role—someone who moves quickly, solves problems across multiple layers, and leads through execution rather than delegation.

What You'll Do

• Build and ship features across the entire stack, including frontend interfaces, backend services, data layers, and AI-powered capabilities

• Design and implement system architecture, including service boundaries, data models, caching strategies, and infrastructure topology

• Own production systems end-to-end, diagnosing and resolving issues across application servers, job workers, databases, and distributed systems

• Lead the integration of AI capabilities from research through production, including prototyping, model evaluation, and deployment behind scalable APIs

• Develop and optimize data pipelines, model training workflows, and inference systems with attention to performance, cost, and scalability

• Design and implement payment and billing systems, including subscription logic, webhook processing, and financial reconciliation

• Contribute across all layers of development, from database migrations and API design to UI components, testing, and deployment workflows

• Establish engineering best practices by setting a high bar for code quality, testing, and documentation

• Mentor and support engineers across the team, helping unblock complex technical challenges

What We're Looking For

• 8+ years of experience building and shipping complex production systems

• Strong full-stack expertise, including modern frontend frameworks, backend APIs, database design, and infrastructure management

• Proven experience working across multiple layers of a system, from UI to backend to infrastructure

• Hands-on experience integrating AI/ML models into production systems, including understanding of model serving and inference pipelines

• Experience building systems that handle financial transactions, including payment processing, subscription management, or reconciliation workflows

• Deep understanding of production systems, including debugging performance issues, analyzing logs and metrics, and maintaining system reliability at scale

• Experience designing and scaling systems in real-world environments under growing demand

• Strong system design skills with the ability to evaluate tradeoffs and adapt based on evolving requirements

• Ability to operate independently, move quickly, and take ownership of high-impact technical decisions

Nice to Have

• Experience with workflow orchestration tools or distributed job processing systems

• Background working with self-managed infrastructure environments

• Familiarity with media, creator platforms, or content-heavy systems

• Experience with cryptocurrency or alternative payment systems

Technology Stack

• React, Next.js, TypeScript, Tailwind CSS

• Node.js / NestJS, Prisma, PostgreSQL, Redis

• Temporal, Docker, Linux-based infrastructure

• Cloud and storage platforms

• Python / PyTorch for AI pipelines

• Monitoring, observability, and CI/CD tooling
