Lead Backend Engineer, AI Platform

Overview

The Lead Backend Engineer on the AI Platform team plays a critical role in building, evolving, and leading the backend systems and engineering practices that power internal products, customer-facing capabilities, AI-enabled workflows, and operational decision-making across the organization. This role combines hands-on backend engineering depth with technical leadership, delivery ownership, and mentorship for engineers working on business-critical systems.


This role contributes to the development and evolution of core backend capabilities, including service-oriented architecture, APIs, workflow orchestration, event-driven integrations, identity and permissions, and operational tooling. In addition, the Lead Backend Engineer will drive buildouts of AI application infrastructure, LLM-powered product capabilities, agentic workflows, retrieval-augmented systems, evaluation pipelines, and shared platform patterns. Success requires strong technical judgment, sound systems thinking, and the ability to guide a team toward simple, scalable, and maintainable solutions in a cloud-based, regulated, high-stakes environment.


The Lead Backend Engineer is expected to operate effectively in a modern engineering environment, using automation, observability, CI/CD, testing, infrastructure-as-code, and AI-assisted development practices to deploy, manage, and improve backend systems. In parallel, this individual will help set technical direction, break down ambiguous problems, mentor engineers, raise the quality bar through design and code review, and partner closely with Product, AI, Data, Operations, and business stakeholders to build both with AI and on top of AI responsibly, securely, and pragmatically.


This is a fully remote position that offers a competitive salary range of $220,000 to $300,000 USD, plus an annual bonus. You'll also receive our excellent benefits package, which includes medical coverage starting on day one and a company-matched 401(k). Compensation may vary based on experience, location, and other job-related factors.

• Make sound technical tradeoffs that balance speed, simplicity, reliability, security, cost, and long-term platform leverage

AI Product & Platform Development

• Lead the design and implementation of LLM-powered backend capabilities, including retrieval, tool use, workflow orchestration, structured outputs, human-in-the-loop review, evaluation, guardrails, and production monitoring

• Establish patterns for integrating AI systems with core services, data stores, document workflows, permissions, audit trails, operational decisioning, and user-facing product experiences

• Use AI-assisted development tools thoughtfully to accelerate software delivery while maintaining strong standards for code quality, testing, security, maintainability, and human ownership of technical decisions

• Partner with AI, Data, Product, and Operations teams to translate model capabilities, business workflows, and user feedback into reliable product experiences that improve over time

Team Leadership & Delivery

• Lead, mentor, and develop backend engineers through technical guidance, design feedback, code review, pairing, coaching, and clear expectations for engineering quality

• Translate ambiguous business, product, and operational needs into clear technical plans, milestones, sequencing, risks, and execution paths for the team

• Coordinate delivery across engineers and partner teams, helping remove blockers, manage dependencies, clarify ownership, and keep work moving with urgency and discipline

• Help create a strong team culture grounded in ownership, high standards, candid feedback, pragmatic decision-making, and continuous learning

Cloud Deployment & Operations

• Deploy, operate, and improve backend services on major cloud platforms such as AWS, GCP, or Azure

• Use infrastructure-as-code, CI/CD, automated testing, and deployment automation to improve release speed, consistency, and reliability

• Monitor production services using logging, tracing, metrics, alerting, and observability tooling to proactively identify and resolve issues

• Support secure, resilient, cost-conscious, and well-documented operation of cloud-based backend infrastructure and application services

Reliability, Security & Compliance

• Build and lead systems with strong operational discipline, including attention to latency, availability, scalability, correctness, incident response, and production support

• Implement and review authentication, authorization, permissions, audit logging, data protection, and secure service-to-service communication patterns

• Establish and maintain standards for API documentation, service ownership, runbooks, operational metrics, change management, release readiness, and production support

• Contribute to practices that support security, privacy, auditability, compliance, and risk management in a regulated environment

Cross-Functional Collaboration

• Partner closely with Product, Engineering, Data, AI, Design, Operations, and business stakeholders to understand workflows, user needs, constraints, and delivery priorities

• Translate business and operational requirements into clean, scalable, maintainable, and secure backend solutions, while helping stakeholders understand technical tradeoffs and delivery risks

• Support downstream consumers of backend capabilities, including product teams, analysts, researchers, AI systems, operational users, and external integrations

• Communicate clearly with both technical and non-technical stakeholders about system behavior, tradeoffs, risks, dependencies, incidents, and delivery timelines

Qualifications

• 5-8+ years of experience building and operating production-grade backend systems, APIs, services, or distributed applications
