Pay Range: $60–$65/hour W2 (No C2C or Sponsorship)

Duration: 12 Months



Introduction

The Planet Group is seeking a Backend Engineer to join a high-impact, remote-first team focused on leveraging Large Language Models (LLMs) to classify and structure massive content datasets. This team is building a scalable system to categorize various forms of user-generated content using state-of-the-art LLM techniques, including retrieval-augmented generation (RAG). If you're a backend developer with production-level LLM experience, strong Go and Python skills, and a desire to work on high-scale systems, this is a rare opportunity to join a fast-moving team at the forefront of AI-driven automation.



Required Skills & Qualifications


  • 4–8 years of professional experience developing distributed backend systems

  • Proven hands-on experience with LLMs, including prompt engineering, automation workflows, and multi-stage RAG pipelines

  • Strong programming skills in Python and Go (Golang)

  • Experience working with distributed systems, microservices, and high-throughput environments

  • Deep familiarity with AWS or Google Cloud, Kubernetes, Kafka, and Redis

  • Ability to debug large systems at scale and contribute across the full development cycle (design, build, test, deploy)

  • Strong communication skills and ability to work cross-functionally in a remote-first environment

  • Demonstrated ability to operate autonomously and unblock yourself without heavy oversight

  • Experience with modern software engineering practices including:

    • CI/CD

    • A/B testing

    • Unit/integration/E2E testing

    • Code reviews and technical documentation





Preferred Skills & Qualifications


  • Background in high-scale consumer platforms or large enterprise tech (e.g., fintech, social, data platforms)

  • Experience planning, managing, and estimating project timelines

  • Past involvement in content classification or information retrieval systems

  • Startup-friendly mindset: proactive, creative, and comfortable with ambiguity



Day-to-Day Responsibilities


  • Build automated systems to classify and tag massive volumes of unstructured content using LLMs

  • Develop backend pipelines that utilize multi-round RAG, vector search, and semantic retrieval techniques

  • Partner with cross-functional teams (Product, Data Science, Engineering) to define and launch new classification workflows

  • Architect durable, observable, and fault-tolerant backend services that scale with user growth

  • Manage and iterate on experiments, including A/B tests and performance tuning

  • Write clean, testable code in Python and Go, with strong documentation and observability

  • Continuously improve the team’s ability to deliver value quickly with high technical standards



Company Benefits & Culture


  • 100% Remote role with flexible working hours (3 hours PST overlap required)

  • Work on state-of-the-art LLM, AI, and content automation challenges

  • Access to cutting-edge tools and infrastructure in a large-scale cloud-native environment

  • Be part of a collaborative team that values innovation, autonomy, and ownership

  • Fast-paced, agile development culture with strong engineering practices
