About The Position

As a Software Development Engineer III on the Platform team at Palmetto, you will play a key role in designing, building, and scaling the core services powering our entire product ecosystem. You’ll work within a microservices architecture built with NestJS, developing and maintaining APIs that are consumed by internal teams and integrated with a broad range of external partners and third-party systems. While this role carries a strong backend and platform focus, you'll also contribute to React-based frontend experiences, building out tools and interfaces that surface platform capabilities to both internal users and external professional teams. You'll collaborate closely with product, design, and fellow engineering teams who depend on the platform you help build and maintain. This role is ideal for a passionate, growth-minded engineer who thrives in an Agile environment, brings ideas to the table, is opinionated but collaborative, and has the technical depth to contribute to platform evolution and system scalability. You’ll work alongside, not for, other team members – contributing your ideas, code, and energy to shape solutions that drive business outcomes and customer satisfaction.

Requirements

• 5+ years of professional software engineering experience.
• Strong proficiency in JavaScript/Typescript (ES6+) and understanding of the JavaScript object model.
• Hands-on experience with NestJS - including modules, providers, dependency injection, guards, interceptors, and pipes.
• Proficiency with Node.js and proven experience designing and consuming RESTful APIs in a microservices or distributed systems context.
• Solid experience building and maintaining Single Page Applications (SPAs) with ReactJS, including component lifecycle, state management, and hooks.
• Experience integrating with external APIs and third-party services; familiarity with patterns for resiliency, retries, and contract management.
• Hands-on experience working with NoSQL/document-based databases (e.g., MongoDB).
• Solid understanding of core web fundamentals (HTML, CSS, security, performance).
• Strong unit and integration testing discipline.
• Familiarity with CI/CD pipelines, code versioning (Git), and modern development workflows.
• Excellent written and verbal communication skills.
• Strong problem-solving skills, a continuous learner mentality, and a commitment to team success.

Nice To Haves

• Experience with event-driven architectures and messaging systems (e.g., Kafka, RabbitMQ).
• Familiarity with API gateways and inter-service communication patterns.
• Knowledge of authentication and authorization patterns (e.g., OAuth, JWT, Auth0).
• Experience with server-side rendering or isomorphic React applications.
• Experience with front-end build tools (Webpack, Vite, Babel, etc.).
• Exposure to containerization (Docker) and cloud platforms (AWS, GCP, Azure).
• Practical knowledge of Agile methodologies and code review practices.
• Enthusiasm for building clean, scalable, and maintainable platform-grade code.

Responsibilities

• Design and implement scalable microservices using NestJS, with a focus on clean module boundaries, dependency injection, and service-to-service communication patterns.
• Develop React-based frontend features that expose platform capabilities, working closely with product and design to deliver polished user-facing experiences.
• Write high-quality, testable, and maintainable code across the full stack.
• Develop and maintain comprehensive unit, integration, and end-to-end tests.
• Diagnose and troubleshoot production issues and propose robust solutions.
• Stay current on emerging engineering capabilities and tools and leverage AI-assisted development tools (e.g., GitHub Copilot, Claude Code) to accelerate development velocity, improve code quality, and reduce time spent on repetitive implementation tasks.
• Participate in Agile ceremonies (planning, grooming, retrospectives) and contribute to meaningful story estimations.
• Engage in architectural discussions, technical design reviews, and contribute to Palmetto's engineering standards.
• Identify and advocate for opportunities to improve system performance, reliability, and developer productivity.
• Partner cross-functionally with product managers, designers, and QA to deliver well-rounded user-centric solutions.
