Lead Software Engineer, AI Email Applications, Artificial Intelligence (AI) Required – Work From Home

As the Lead Software Engineer, AI Email Applications, you own the engineering layer that turns Artificial Intelligence (AI) capability into a reliable product. You will shape the architecture across backend services, APIs, and client applications, while leading a small team of senior engineers. This is a hands-on leadership role. You stay close to the code, make critical architectural decisions, and ensure the system remains fast, reliable, and coherent as it scales.

This position is 100% Remote.

MUST BE WILLING TO TAKE A 60 MINUTE CODING ASSESSMENT.

Lead Software Engineer Responsibilities:

  • Own the application engineering strategy and execution across backend, mobile, and desktop.
  • Design reliable systems for AI-powered workflows, including state, orchestration, tool use, retries, fallbacks, and failure handling.
  • Build the APIs and abstractions that connect Artificial Intelligence (AI) systems to real-world product experiences.
  • Lead a small, senior engineering team and raise the technical bar through design reviews, code reviews, and hands-on mentorship.
  • Make high-impact trade-offs across latency, reliability, cost, security, and user experience.
  • Establish strong production foundations: observability, monitoring, testing, and operational excellence.
  • Partner closely with Machine Learning (ML) leadership to turn model capabilities into robust, shippable product experiences.
  • Move quickly while keeping the architecture simple, maintainable, and ready to scale.

Lead Software Engineer Outcomes:

  • Production systems are observable, monitored, and stable under real-world load.
  • Decisions consistently balance speed, cost, reliability, and user experience.
  • Features across backend, mobile, and desktop work smoothly and reliably.
  • Latency and reliability improve measurably over time.

Lead Software Engineer

Qualifications:

  • Artificial Intelligence (AI) experience is required.
  • Significant experience leading application or product engineering for complex systems.
  • Strong hands-on background building and shipping backend systems used in production.
  • Experience building AI-powered products or systems that integrate with modern Machine Learning (ML)/Large Language Model (LLM) capabilities.
  • Strong technical judgment and the ability to make decisions with incomplete information.
  • Comfortable working across backend and client platforms, with deep expertise in at least one.
  • A strong bias toward ownership, shipping, and learning from real-world usage.
  • High standards for code quality, reliability, and engineering fundamentals.

Benefits include medical insurance, Dental, Vision, Savings Plan Options, PTO, etc.
