Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of Justworks as an employer.

What you need

  • 5+ years of backend engineering experience building and operating production systems
  • Hands-on experience with LLMs and AI agents (orchestration, RAG, tool/function calling, or similar)
  • Strong API design and system integration skills
  • Proven ownership of complex projects in ambiguous, early-stage environments

Nice to have

  • Product-minded: questions requirements and contributes to product decisions, not just execution

What you get

  • Welcoming and casual environment
  • Great benefits
  • Wellness program offerings
  • Company retreats

Worth weighing

  • No specific mention of remote work options beyond hybrid
  • Fast-paced, early-stage environment may require adaptability
  • Role involves significant ownership and initiative without explicit instructions
