Principal Full Stack Software Engineer (AI Developer Workflows)

Quick Facts

• Role: Principal Full Stack Software Engineer (AI Developer Workflows)
• Scope: Technical leadership across UI, developer tooling, AI agent/prompt design, backend systems, and cloud infrastructure

Description

Principal Software Engineer role focused on defining and building next-generation AI-powered software development workflows. You will set technical direction and lead major multi-quarter initiatives spanning client applications, backend services, agent systems, cloud infrastructure, and developer tooling—while staying hands-on in design and implementation. The work will shape architecture and influence how developers worldwide design, write, review, test, and maintain software.

Responsibilities

• Set technical and product direction for significant areas; translate evolving product vision into scalable architecture and engineering strategy
• Lead complex, multi-quarter initiatives across client, backend, agent systems, cloud infrastructure, and developer tooling
• Design AI-powered workflows that generalize across languages, codebases, environments, and organizations while remaining intuitive, reliable, and safe
• Make high-consequence architectural decisions under ambiguity, balancing rapid learning with long-term system quality
• Identify high-leverage opportunities across team/product boundaries and drive execution from exploration to launch and iteration
• Partner with product, design, research, infrastructure, security, and go-to-market to build coherent developer experiences from model capabilities
• Collaborate with developers, open-source maintainers, startups, and enterprise users to uncover unmet needs and foundational opportunities
• Establish patterns and standards for reliability, observability, performance, experimentation, and evaluation
• Review critical designs, mentor engineers, improve engineering practices, and act as a technical multiplier
• Contribute directly to implementation for novel or technically demanding problems requiring integration across layers

Requirements

You might thrive in this role if you have led technically complex, user-facing systems; combine deep engineering expertise with exceptional product judgment; create clarity in ambiguous spaces; remain hands-on while mentoring others; understand modern development workflows and AI-agent interaction/system needs; have experience building or operating AI-powered products (including nondeterminism, evaluation, latency, reliability, safety); make strong tradeoffs; learn from user evidence; and communicate effectively across cross-functional and executive audiences.

Benefits

• Highly product-oriented technical leadership role with major product and architecture impact
• Senior individual contributor position focused on both strategy and hands-on execution
• Opportunity to shape developer-facing AI workflow experiences across the software development lifecycle
