Job Level

Lead

About the role

  • Own the technical direction and execution of Lime’s CX Automation platform, spanning self-service, AI-driven decision-making, and human-in-the-loop workflows.
  • Architect and build scalable backend systems that integrate internal APIs and third-party platforms to automate high-volume rider issues and reduce manual support effort.
  • Design and operate decision engines and automation workflows that take real actions (e.g. ending trips, issuing refunds) with clear guardrails for fraud, abuse, and rider trust.
  • Partner with Product and CX Operations to translate support policies and edge cases into executable automation logic, prioritizing work based on volume, cost impact, and risk.
  • Drive foundational platform investments (e.g., API coverage, workflow infrastructure, observability) required to scale automation reliably.
  • Measure and improve automation effectiveness using data

Requirements

  • 6+ years of professional software engineering experience with a track record of owning and operating production systems at scale.
  • Strong backend engineering experience building reliable, scalable services and APIs that support high-volume, customer-facing workflows.
  • Experience building applied AI or automation systems in production, including decision logic, workflow orchestration, or human-in-the-loop processes (deep ML research experience is not required).
  • Demonstrated ability to set technical direction and drive multi-quarter initiatives, making sound architectural and tradeoff decisions in complex, ambiguous environments.
  • Proven judgment in designing systems with real-world constraints, including cost efficiency, operational risk, abuse prevention, and customer trust.
  • Clear and effective communicator who can collaborate across Product, Operations, and Engineering to solve business problems.
Benefits
  • Comprehensive Health & Wellness: A choice of medical, dental, and vision plans. We also provide company-paid life and disability insurance and company-funded mental health benefits.
  • Financial & Retirement Planning: 401(k) plan with both pre-tax and Roth options, and access to a Health Savings Account (HSA) with a monthly company contribution.
  • Family & Fertility Support: Paid parental leave for birthing and non-birthing parents, plus fertility and family-forming benefits.
  • Paid Time Off: Unlimited vacation, paid leaves, and 10 company holidays.
