Summary of Role

As a Software Development Engineer III at Palmetto, you will play a key role in designing, building, and scaling critical data ingestion pipelines and 3rd party integrations that connect hundreds of thousands of solar energy and HVAC systems to our platform. Working primarily with NestJS, TypeScript, MongoDB, and Google Cloud Spanner, you'll architect and maintain robust integrations with third‑party manufacturer APIs that power downstream systems across the entire company. You'll work hands‑on building resilient microservices, designing event‑driven architectures, and solving complex problems around data consistency and data ingestion at enterprise scale. Your work will directly impact product teams, analytics, customer support, operations, and business intelligence systems that depend on reliable, mission‑critical data.

This role is ideal for a passionate, growth‑minded engineer who thrives in an Agile environment, brings ideas to the table, 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 enable teams across Palmetto to deliver exceptional customer experiences.

• Diagnose and troubleshoot production issues and propose robust solutions.
• 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.

Team & Culture

• Actively participate in peer code reviews with a focus on knowledge sharing, mentorship, and maintaining high‑quality code standards.

• Demonstrate an ownership mindset by anticipating future needs and contributing to long‑term technical roadmap discussions.

• Experience with message queues and message brokers.
• Hands‑on experience working with NoSQL/document‑based databases (e.g., MongoDB).
• Expertise in solving complex problems related to data consistency and ingestion at enterprise scale.
• Strong unit and integration testing discipline; TDD experience is a plus.
• 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.

Preferred Qualifications

• Experience with NestJS or other Node.js frameworks beyond Express.
• Familiarity with server‑side rendering concepts and isomorphic React applications.
• Knowledge of authentication and authorization patterns (e.g., OAuth, JWT).
• 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, pair programming, and code review practices.
