About Our Client

Our client is a leading AI-powered go-to-market platform used by millions of users and more than 500,000 companies globally.

Their platform helps sales, marketing, and revenue teams find prospects, engage customers, and convert opportunities into revenue. The company combines one of the largest B2B contact and company databases in the market with an AI-native platform built to help revenue teams operate with more intelligence, automation, and efficiency.

Our client is profitable, growing quickly, and rebuilding its product around AI and agents. This is an opportunity to join a high-performing engineering organization at a defining moment in the company's technical evolution.

About the Role

Our client is hiring a Principal Software Engineer to set technical direction across the engineering organization.

This is a senior individual contributor role for someone who can own the hardest, most ambiguous, and highest-stakes technical decisions across product, platform, infrastructure, and AI-native systems.

This person will help shape the product for years to come, partner with engineering and product leadership, and serve as a force multiplier across multiple teams. The right candidate has the technical judgment, architecture depth, and influence to align senior engineers and leaders around company-defining technical bets.

What You'll Do

• Own technical direction for the company's most critical and ambiguous engineering problems
• Make long-term architectural decisions across product, platform, distributed systems, and AI-native infrastructure
• Set technical strategy for rebuilding the platform around AI and agents
• Translate high-level technical strategy into direction that engineering teams can execute
• Raise the engineering bar through standards, patterns, architecture reviews, and technical decision-making
• Mentor and multiply the impact of senior engineers across the organization
• Partner with engineering and product leadership as a peer on long-term technical direction
• Use AI-assisted development and agents to move faster across design, investigation, and implementation
• Define practices that help other engineers adopt AI-native engineering workflows
• Identify opportunities where AI can reshape not just how fast the team ships, but how the product itself is built

What We're Looking For

• Proven track record setting technical direction across an engineering organization
• Experience shaping product or platform architecture across multiple teams
• Deep expertise in distributed systems, architecture, reliability, scale, and cost tradeoffs
• Strong judgment in ambiguous, high-stakes technical environments
• Ability to align teams and senior technical leaders around complex architectural decisions
• Experience multiplying the output of senior engineers through design, review, mentorship, and technical leadership
• Genuine, current fluency with AI-assisted development tools and agentic engineering workflows
• Clear point of view on how AI will change engineering, product development, and platform architecture
• Strong communication skills with the ability to influence engineering, product, and executive stakeholders
• Ability to operate at both strategic and technical levels without losing connection to execution

Relevant technologies include:

• React
• Ruby and Ruby on Rails
• Python
• MongoDB
• Elasticsearch
